Trevor Galbraith Editor-in-Chief

2010 gets off to a flying start Barely had the ball dropped in Times Square or the chimes of Big Ben finished welcoming in the New Year than I was off on the first of my many trips this year—this time to Brazil, a fascinating country that has enjoyed eight straight years of strong growth, achieving 5.1% in the last quarter without the aid of any stimulus bill. Indeed, Brazil was largely unaffected by the global economic downturn, and as future hosts of the FIFA World Cup (2014) and the Olympics (2016), the country is bubbling with enthusiasm and activity. But the reason for my visit was not to take in the cultural sites, but to follow up on the many reports we had received from customers about the strong manufacturing growth in Brazil and Argentina. After months of intensive research, we were confirming the final details on Global SMT & Packaging’s first major trade show and the only focused electronics manufacturing event in Brazil. GEM (Global Electronics Manufacturing) Expo Brazil 2010 will be held October 5-7 at the Expo Center Norte in Sao Paulo. This state-of-the-art venue is located close to the major international airport and is the premier site for major engineering events in the city. A comprehensive technical and training program is planned to be held alongside the exhibition and we hope to bring you more information on that in the coming weeks. GEM Brazil will be managed by our new director of global events, Delio Destro, and his assistant, Cibele Brognoli Duarte. Both bring a wealth of experience of the electronics manufacturing in Brazil and events organizing. Meanwhile, over on another continent—this time India, we are celebrating the addition of some new team members ahead of the impending launch of Global SMT & Packaging— South East Asia. This quarterly magazine

will be published out of our New Delhi office, in English and will be distributed free of charge to EMS manufacturers in India, Thailand, Malaysia, Singapore, The Philippines and Hong Kong. With such large commitments as we leave the world recession behind, many of you may think that we are being extremely bold hiring new people and launching major new endeavors at this time. You are right—but it is only through bold initiatives such as this that we will grow and prosper as the world returns to growth. All the economic indicators and the electronics indicators are pointing in a positive direction, although most pundits are predicting a slow growth pattern. I certainly agree, but the recent wave of new enticing electronics tablets, 3D TVs and other gizmos at CES last month gave me even greater hope that, for electronics manufacturers at least, the economic downturn is truly behind us. —Trevor Galbraith

Title

Simple solderability testing of package on package (PoP) devices

Bob Willis Some subcontractors have been asked to build stacked packages where customers do not have a dipping process for PoP assembly or are not confident with the process. They have felt more comfortable with the pre-stacking process being undertaken first.

Simple solderability testing of package on package (PoP) devices Solderability testing of stacked packages that have already been through a prestacking process can be fairly simple to perform. The test may also be applied to single parts prior to stacking or parts due to be stacked. The test method is subjective but can prove very effective, and with care, the tested components do not necessarily need to be scrapped. When the components are originally made, the solder paste or balls are reflowed in a nitrogen atmosphere which will maintain a solderable surface and not increase the oxide formation. In some cases, the stacking process of multiple parts may be conducted in a process with a higher concentration of air. Some subcontractors have been asked to build stacked packages where customers do not have a dipping process for PoP assembly or are not confident with the process. They have felt more comfortable with the prestacking process being undertaken first. A suitable quality PoP dipping paste can be placed on the surface of a glass slide or ceramic tile using a mini stencil with an opening of 0.020” and foil thickness of 0.004”. Alternatively, placing the package terminations of the pre-pasted package on a test substrate previously coated with a defined thickness of the paste is the best solution. Just like the dipping process used in production it provides a similar volume of paste used in manufacture rather than using a stencil. This allows a test of the paste performance for solder balling after reflow inspection can be conducted through the glass around the balls. If a ceramic tile is used, the package must be removed from the tile before balling can be

assessed. Although many pastes are designed for nitrogen, suppliers are offering air reflow products, which is what the industry needs. One of the challenges to the producer is that most pastes have very small particle size, increasing surface area and oxide formation possibly leading to increased solder balling and fines. The lower metal content can also increase the level of paste slump during preheating. Solderability testing method Select the PoP package for solderability

assessment and place the component on to the dip paste surface. The thickness and surface of the paste must be defined and duplicate the production conditions. The components are then placed on the surface of the test substrate for testing. Place the slide on the surface of a sample board and, using the same profile parameters, pass the substrate through the reflow process. Care needs to be taken for component floating off the surface of the test substrate. This is more likely on vapour phase than with convection.

Figure 3. Example of poor flux and paste coated package balls rejected during inspection. There are two options: throw the components away or clean the parts for reuse. Often subcontractors are not provided any contingency by customers!!!!

After reflow, the sample components are lifted from the surface and the balls on the package can be examined for satisfactory wetting. Close examination of the tile will show any evidence of solder balling in the flux surface. Ideally there should be no evidence of solder on the glass or in the flux residues. All the solder should have wetted and full coalesced with the balls. A further reason for conducting this test is for possible use when components have been cleaned after being found as spit-outs from the placement process after dipping in paste or dip flux. A recovery process that may be a reality for some users!! The Package On Package Design, Assembly and Defect Guide CD will be released during the IPC APEX 2010 Exhibition in Las Vegas.

The index was set to average 100 in 2000. The indicator, comparable to the company’s other global regional semiconductor industry indicators for North America, Asia Pacific and Japan, is a forward-looking composite index that forecasts six months ahead, on average, business activity in the region for sales for semiconductors. www.e-forecasting.com Semiconductor inventories set to remain lean in Q1 After dramatically cutting bloated inventories in 2009, global semiconductor suppliers are expected to maintain lean stockpiles in the first quarter of 2010 in order to maintain profitability amid uncertain economic conditions, according to iSuppli Corp.

Days of Inventory (DOI) among semiconductor suppliers are expected to decline to 68.3 at the end of the first quarter, down from 68.5 for the fourth quarter of 2009. With DOI already 2.9 percent below the historical average in the fourth quarter, first-quarter inventories are expected to be 6.9 percent less than the norm. While inventory in the first quarter will remain at about equilibrium level with demand, stockpiles will be at very low levels—even bordering on shortages for a few specific devices. Continued tight management of inventories will help the semiconductor industry to attain double-digit percentage growth in 2010. After a decline of 12.4 percent in 2009, worldwide semiconductor revenue is set to rise by 15.4 percent in 2010, iSuppli predicts. www.isuppli.com Digi-Key, Spectra Symbol announce worldwide distribution agreement Electronic components distributor Digi-Key Corporation and Spectra Symbol signed a global distribution agreement.

Metallization options for optimum chip-on-board assembly

Metallization options for optimum chip-on-board assembly Mukul Luthra, Waterfall Technologies, Halton Hills, Ontario, Canada When COB is merged within mainstream SMT, the choice of metallization has to serve both the SMT process and bonding—that choice can be a make or break factor. In the initial migration of die bonding onto organic substrates, the Au/Au and Au/AlSi system was more or less defacto—‘inherited’ from the packaging backend. Driven by cost pressures, alternative metallic systems have come under scrutiny, the options refined and made viable. This paper examines and explains to the SMT professional the strengths, limitations, pros and cons and science behind the goldgold, gold-aluminum, goldcopper, gold-silver, aluminumaluminum, aluminum-nickel and copper-aluminum systems and examines how each produces different metallurgical interactions with the various die pad and substrate metallizations and how the resulting intermetallic structures and growth impact reliability & cost.

Keywords: Chip On Board, SMT, Metallization This Paper was published in the proceedings of the SMTA International Conference on Soldering and Reliability, Toronto, May 2009

Technology acquisition Within the mainstream SMT (surface mount technology) assembly process, wire bonding of bare dies directly on the PCB (printed circuit board) substrate alongside other soldered components has long since been practiced and continues to be deployed across a vast scope and range of COB (chip on board)-SMT applications. These applications range from the very low end, low cost ‘throw away’ items to high performance, complex assemblies. The IC (integrated circuit) backend industry, with its decades of maturity and understanding of metallurgy related in particular to wire bonding, finds itself acquiring and adapting SMT know-how to the field of packaging. It is interesting to note that content of leading technical journals aimed at the IC industry now extending into SMT areas with appearance of articles on subjects such as solder paste & printing and reflow ovens.1-3 The SMT industry however may find it relatively harder to deal with the complexities of wire bonding associated with the COB-SMT merge—this information has been generally acquired through much ‘hands-on’ and trial basis. This paper reviews the metallization options and interactions for COB while considering the needs of the bonding process and soldering. Several real life product examples using COB-SMT are included to illustrate the metallization used covering a diverse range of product positioning. The content is meant to serve the SMT professional familiar with soldering process interactions but requiring an understanding of the COB-SMT merge. Market environment & trends A principal factor driving the phenomenal growth of the electronics consumer segment are mobility and hand held products that have been flooding the market, with each successive generation

offering performance and features at prices unimaginably by yesterday’s standards. Associated with this growth are short product life cycles and steady price erosion—a trend that has become deeply entrenched in the consumer mind and taken for granted. This prevailing market ‘flavor’, in particular as associated with mobility products, is a predominant driver of (and in turn been enabled by) the migration from lead frame based packaging towards organic based interconnection trends. A convergence between IC backend processes and ‘traditional’ SMT PCB assembly has surfaced, the boundaries of the two becoming diffused. Apart from the size and footprint advantages, organic based packaging offers a significant spin off—it is a platform readily adaptable by the IC backend towards attaching multiple dies and other active and passive components on a substrate within an IC (ball grid arrays or chip scale packages in the modern context). After over-molding, the resulting assembly creates a highly functional device. SiPs (systems in package) and MCMs (multi chip modules) are examples exploiting this advantage.

www.globalsmt.net


Metallization options for optimum chip-on-board assembly

Thus after decades of packaging typically a single die on a metal lead frame, the face of IC backend is being permanently transformed and acquiring the flavor of a PCBA (printed circuit board assembly)-like process, albeit one involving dies and SMT all within the package itself. Other than the final over-mould and ball attach if applicable, the process replicates the COB-SMT concept as deployed within the mainstream SMT industry. COB metallization layout considerations—some basics In the commonest COB layout (Figure 1), bond fingers pads are arranged in an array around the die (fan out only). P (power) and G (ground) rings may be included within the Signal I/O (input/output) bond finger ring. Several P & G rings may be allowable; however when present, rings must be covered by solder mask except of course at the bonding sites. This not only protects the metallization but also prevents any inadvertent shorts. Bond finger pads must respect PCB design rules for line spacing and width. Solder mask openings in the bond finger are only as to allow bonding in the open areas. (Figure 1 bottom left). Further information may be found in Reference 10. Die placement area metallization If electrical conductivity to die is required— then die placement area metallization is needed. Figure 2 shows a typical example of pad sizing, wire lengths and layout based on a real example in a pocket dictionary for one of the dies of approximately 9.5 mm by 5 mm with an I/O count of 184. The pad length shown enables a one time re-bond (rework). For reliability reasons, re-bonds are never done over the previously bonded spots on the pads.4 In high reliability, industrial applications or areas such as packaging, this metallization must provide a barrier to Cu (copper) migration into Si (silicon) die. Au (gold) over Ni (nickel) is used for high end applications with Ni providing the needed barrier for Cu migration but for the low end spectrum Ni alone (without Au) is used and is adequate for low cost applications. As a generic rule in COB, dies for power applications are not advised, due to the significant Cte (coefficient of thermal expansion) mismatch between the Si die and organic substrates4. Over-molded assemblies such as SiPs or MCM are more robust and tolerant to this aspect. Placement metallization may be designed to improve thermal performance if needed

for a specific situation. This would take the form of vias (copper filled) in the placement metallization connected to the bottom and/or inner layers. If electrical conductivity to the die itself is NOT required, placement areas with solder mask become feasible. The significant variable to consider are the compatibly of the die bonding material to the mask, the mask cure condition, absorbed moisture and contamination all of which can affect the surface activation energy and hence the adhesion of the die to the substrate. With solder mask the coplanarity in the placement area becomes an important variable—even a few mils of die tilt can lead to mis-bonds during wire bonding process.4 Bonding variables fishbone diagram Figure 3 shows the variables’ fishbone tree. An SMT professional can readily appreciate that the process itself is far more complex and sensitive to any encountered in the mainstream SMT world. When the variables for both the SMT process and COB are combined, the resulting fish bone diagram appears formidable. Solder joint reliability is to the SMT world as bond reliability is to the bonding process—the latter co-related to bond pull strength. Clearly as evident from Figure 3 the choice of metals and the resulting bond metallurgy play a significant role in attaining this important success parameter. Understanding of both the metallurgical interactions in COB as well as soldering metallurgy is essential in the field of process development and in failure analysis.

on. Amongst the important mechanical considerations influencing bonding wire selections are: 1. Tensile Properties 2. Elongation (EL) 3. Break Load (BL) [Ref: ASTM (American Society for Testing & Materials) Standard F72] Electrical properties are application dependent; however it must be borne in mind that each material produces different metallurgical interactions with the die pad metallization and substrate metallization. Since substrate metallization interacts uniquely with different solder alloys it is therefore an important consideration in

balancing the needs of wire bonding and soldering. Bulk properties comparison of various materials appears in Table 1. Gold bonding wire The ductility of gold provides the flexibility needed for good loop formation. Gold has excellent electrical and thermal properties and being inert (gold is a noble metal) makes it well suited to the bonding process. Gold wire is widely used in bonding applications in both ball bonding and wedge bonding applications producing very reliable bonds to both Al (aluminum) and Au (gold) surface metallization. The needs of flexibility, loop retention and bondability have to be balanced.

Pure gold wire is too soft and is usually stabilized with dopants such as Be (Beryllium) of around 5-10 PPM (parts per million) or Cu (copper) around 1030 PPM. Based on purity, gold wire is classified into various ranges from 99 % (2N gold) to 99.99 % (4N gold). Beryllium doped Au wire is 10-20 % stronger than Cu doped and hence better suited for higher stress applications like high speed automated bonders. Gold wire is typically supplied in an annealed condition to prevent unwanted break offs during initial bond formation. Table 2 is an example of a comparison of the properties of 4N versus 2N gold as developed by one particular supplier for ‘ultra stiff’ gold wire bonding applications3. It is interesting to note the differences in the minor and the major dopants levels (none in the case of 4N wire). Considerations with gold wire bonding Surface cleanliness and contamination are both critical to bond strength. Surface finish of the bonding metallization is critical to prevent bond tool capillary clogging. Some of the trade—offs with gold bonding wire are: a. It is an expensive material b. Uses expensive bonding tools—ceramic for ball bonding, titanium carbide for wedge bonding c. High temperature bonding is needed which is a possible source of die stress. d. Limitations in heating the PCB (organic) substrate metallization Although gold wire bonds can be made without substrate or wire heating, reliable gold bonding requires heating the bonding metallization and wire to a high temp. Ball bonding requires a temperature in the range of 220-250˚C while reliable Au wedge bonding can be accomplished at a lower temp of around 150˚C. Heating a metal lead frame or die pad (for example pre-plated Cu lead frames as used in IC manufacturing) given the form factor, high thermal conductivity and uniform thermal mass is relatively easier compared to organic substrates. Organic PCB substrates variables—lower thermal conductivity, complex thermal mass distribution, size, Cte, and whether the PCB is populated or unpopulated make it non-ideal to create localized heating at the substrate pads. The process may slow down throughput and/or lead to higher stress conditions marginalizing the over-all assembly reliability.

Figure 4. Al-Si phase diagram.

Al -Si (silcon) bonding wire Small diameter Al wire is often used for wedge bonding and offers relatively good fatigue resistance. As in the case of gold, pure Al is too soft to draw into small wires so it is alloyed with approx 1% Si (silicon) to provide the desired properties of load and elongation. Lightweight Al-Si wire is very reliable but is much lower in cost compared to Au. It is used extensively with low cost wedge bonding tools (tungsten carbide) and since Al bonding can be done at room Temp. It is a process well suited to organic substrates and therefore an ideal default choice in a most low to mid cost COB applications. Figure 4 shows the Al-Si phase diagram. As can be seen, 1 % Si exceeds the solid solubility limits of Si in Al at room temp. Si precipitation can cause stress risers and possible wire fracture and is one of the failure mechanisms associated with heel cracks. Small diameter Al-Si wires are usually heat treated (partially annealed) to disperse Si uniformly. Large diameter wires are heat treated before and after final drawing. Al-Mg (aluminum-magnesium) bonding wire Al alloying with Mg is an alternate to alloying with Si and actually offers certain advantages. Figure 5 shows the Al-Mg Phase diagram. Mg solid solubility in Al is better than the 1 % maximum of Si dissolved in Al. Al with 1% Mg can be drawn into fine wire with similar strength as Al with 1% Si. Al-Mg gives satisfactory bonding and is superior to Al with 1% Si in fatigue failures. It also shows superior ultimate strength after high temperature exposure. Despite the Al-Mg wire alternative

with some of its advantages its use has remained less prevalent in the industry compared to Al-Si, which has become widely accepted in the industry. Copper bonding wire Cu (copper) ball bonding has seen more recent usage and in particular Cu ribbons have been receiving considerable attention. Cu is economical, has excellent heat and electrical conduction—hence smaller wires possible—and is resistant to sweep during plastic encapsulation. Cu to Cu bond is possible, but with Cu the major issue remains bondability. Since Cu oxidizes readily, bonding in inert atmosphere is needed, which somewhat negates the cost advantages with Cu bond wire. Cu-Al intermetallic growth rate is lower than Au-Al, and provided the initial bondablity issue is addressed via inert gas, Cu offers better reliability than Au wires to Al pads with 0.4-4.0 mil wire diameters. However Cu is harder than Ag and Al (Table 1) and risks die cratering or pad metallization damaged—a harder pad metallization is required for Cu wire bonding. Currently Cu usage is limited to mainly high-end usage (CSPs, QFNs)—it has limited usage in COB applications at the moment. Metallurgical systems The next section reviews the metallurgical interactions in the bonding process, the substrate metallization options together with soldering considerations in the light of the COB-SMT merge.

Gold wire-gold plated pads The gold-gold bond being a mono metal system is extremely reliable. It is not

subject to interface corrosion—there is no intermetallic formation and no bond degradation. Even a marginal Au-Au bond performs well despite time and temperature. As mentioned before Au is best bonded with heat. Cold ultrasonic Au-Au bonding is possible but is less reliable. Thermosonic bonding is preferred and is most common, however thermo compression bonding is possible. Bonding is highly affected by surface contamination. Au-Au bonding is used in high-end COB application and within the IC industry for applications such as SiP and MCMs. Use of plasma etching to improve surface activation is extensively used in the high-end process. Au plating thickness for the bond pad metallization is target application (reliability) dependent. For high reliability bonding an ultra pure, soft Au (hardness 60-80 Knoop) in the range of 30-100 micro-inches is typical. Soldering vs. bonding on gold pads This subsection examines the Au metallization in its SMT soldering aspects and conflicts and options vis-à-vis wire bonding. Au offers excellent co-planarity, fine features, and high-density circuits; it is essential in HF (high frequency) applications. Au can withstand multiple reflows, has good corrosion protection and excellent wetting. The main issues with Au are high cost and hard-to-manage plating process. ENIG: Many segments of the industry have (or are) shying away from the ENIG (electroless nickel immersion gold) process as a surface metallization for fears of ‘black pad’ defect, an issue which has received considerable attention and continues to be debated. With the prevalent use of the

ENP (electroless nickel phosphor) process, which co-deposits phosphor in the Ni plating, the impact of phosphor content in the ENP plating on bond reliability and solderability has been the subject of several studies.8 Traditionally 6-8% P content has been used, but some recent studies show otherwise with use up to 10-12% P content producing a more favorable, corrosion resistant Ni surface morphology, an important variable, making it less prone to attack by the subsequent Au plating layer or by the eventual soldering process.8 In the author’s experience and from a metallurgical standpoint, a well controlled9 and specified ENIG process offers an excellent surface finish for both soldering (with Sn/Pb and Pb free solders) and wire bonding, but the ideal thickness requirements for the gold film are quite different for the two interconnection methods. For soldering purposes, the Au must be a dense (not porous), thin film whereas for bonding it should be thick, pure ‘soft’ gold. The general structure favored for soldering applications is a ‘dense’ gold of around 2-4 micro-inches over an underlying Ni layer of around 200-240 micro-inches6-9. The MIL QQ-N290A Standard specifies 200 micro-inches of Ni between the Cu and Au layer as a Cu diffusion barrier. The IPC 4552 ENIG Standard specifies a minimum Au thickness of 0.05 μm (2 micro-inches) to statistically allow for process variability. It also caution on possible appearance of ‘black pad’ issues when immersion gold thickness approaches 0.25 μm (10 micro-inches). The Au layer acts as a sacrificial film, protecting the underlying metal and needs to be thin enough to be ‘consumed’ by the Sn during soldering, with the resulting AuSn IMCs dispersing into the bulk solder fillet. The bond is thus formed to next layer—Ni or Cu as the case may be—which

must be active other wise the Au purpose is defeated. Soldering to thicker Au films meant for bonding application results in a large percentage of AuSn IMC precipitating at the solder joint to pad interface risking solder joint embrittlement and low cycle life. So with COB-SMT, the ideal practice with Au would be to follow the structure desirable for soldering combined with selectively plated ‘thick’ gold at the bonding sites. This process is costly and used mainly in the high end, ‘pricey’ COB applications (Figure 12). If the product positioning does not justify it, a compromise has to be made in which case the ‘thin’ gold favoring soldering is chosen—it provides a product life cycle commensurate with product expectation. DIG (direct immersion gold): This is a relatively new process to the industry and plates the Au directly over the Cu7. The Au film properties (thickness, porosity, morophology, etc.) apply to the DIG process as in as much as they do to the ENIG; however during soldering the Sn bonds to the Cu forming SnCu IMC which have been documented to have a higher growth rate than the SnNi IMC layer11, hence a lower reliability may be expected compared to ENIG, but it may well meet the life cycle of many products depending on their price position. DIG field experience is limited at this stage in COB applications but it ‘appears’ well suited and cost effective. Gold wire-aluminum die pads Gold-aluminum is very common in wire bonding process for COB applications. However, there are reliability issues over time. It is easily subject to Au-Al IMC layers and Kirkendahl voids. IMC formation is accelerated with operating time and temp. and 5 IMC layers are formed as listed below (Figure 6). Au5 Al2 (tan color) [some studies suggest Au8Al3] Au4Al (tan color) Au2Al (metallic grey color) AuAl (white color) AuAl2 (deep purple color) It is believed that initially AuAl2 forms at the Au-Al interface then transforms to other IMCs with time & temp. Gold-aluminum intermetallic growth In a well control ball bond process, gold aluminide IMC growth shows relatively planar morphology. IMC initial growth

rate is believed to be parabolic settling to about 3-4 μm (micrometer) over time. At high temperatures (175˚C), the Al pad converts to IMC-Au5Al2 (gold side) and Au4Al (pad side) predominate in the IMC layer. Au4Al may also grow by consuming Au5Al2—see Figure 6. Au4Al is susceptible to corrosion by epoxy molding compounds used in COB and may also oxidize. Gold wire-copper pcb pads Gold bonding to Cu copper pads is rarely used in COB but is possible. 3 IMC phases are formed: Cu3Au AuCu Au3Cu Formation of IMC decreases bond strength at high temperatures (200 to 325˚C). Kirkendahl voiding can occur due to Cu migration. Bond strength degradation is dependent on micro-structure, bond quality and impurities in the Cu. Cleanliness is extremely important for bondability and reliability when bonding to Cu. Use of inert gas (argon) shielding improves bondability and reliability, prevents Cu oxidation, and is needed for curing polymer die attach material. Soldering Aspects: While Cu with OSP (organic solderability preservative) would be a good choice for soldering for products aimed at the low end spectrum, OSPcoated pads are not useable ‘as is’ for wire bonding. The alternatives of Cu/OSP pads for soldering and selectively plated (Au , Ag or Ni ) pads for wire bonding, while feasible, again negates the cost advantage and is hard to justify. Use of inert gas is not justifiable by products at this low price point. Gold wire-silver pads The Au-Ag is very reliable for long-term at high temperatures. Au-Ag do not form intermetallic compounds. Au wire bonds to Ag lead frames or Ag-plated pads have been successfully used in high volume production for many years. Ag bondability issues are caused by contaminants like sulphur, which tarnish the silver plating. Au-Ag high temperature thermosonic bonding is done at approx. 250˚C and improves bondability by displacing the tin sulphide films. Use of Ag is currently not prevalent in COB applications for cost reasons and thermosonic bonding requirement. Soldering Aspects: The IAg (immersion silver) process is similar to ISn (immersion tin) except it uses electroless silver deposits. IAg is being promoted as an alternative to

Au (due to ‘black pad’ fears with ENIG— see the relevant section further on)—and it can be adopted into COB applications. However, Ag metallization on solder pads is not free of solder joint reliability issues. Microporosity at the Ag-Cu interface occurring from the silver plating process (corrosion of the Cu surface) is being reported and deemed as a reliability threat to solder joints. Ag solderability can easily degrade in contact with Sulphur compounds. Thickness depends on two types chemistry for I-Ag: “Thin” silver, minimum 0.05 microns [2 micro-inches] “Thick” silver, minimum 0.12 microns [5 micro-inches] These thickness values are expected to guarantee a minimum one-year shelf life. Upper thickness limits for both types I-Ag were not established in the initial release of the IPC-4553 Immersion Silver Standard. However I-Ag is not an allowable finish for Class 3 acceptance. Another reason why Ag is being promoted is to eliminate tin whisker issues. Costs are similar or marginally more than immersion tin. Use of Ag is relatively new and not common in the high volume, cost sensitive COB segment. It needs further field experience & volume usage to

understand the long term impacts. Aluminum wire-aluminum die pads Al-Al bonding is an extremely reliable system. Being a mono metal bond, it is not prone to IMC formation and it is not prone to corrosion. Al-Al bond is best done ultrasonically. Al-Al thermocompression bond is possible by high deformation. Al-Al wedge bonding is very predominant in COB applications—it is the mainstay of the low cost, “throwaway” product range and also often used in the mid-end products.4 Aluminum wire-nickel pcb pads Al-Ni bonds are typically made with large diameter wires greater than 75 mm (3 mils). Large wires bonds are less prone to Kirkendahl voids and galvanic corrosion. Ni provides bonds that are more reliable than Al-Ag or Al-Au. Electroless Ni on pads from boride or sulfamate base systems gives reliable bonds Al to Ni pad bonding remains very popular in COB applications-it is low-cost yet reliable. Bondability is affected by Ni surface oxidation and measures to improve Ni pad

Soldering aspects with Ni Pads: Measures mentioned above to improve bondability also apply to improve solderability. electroless nickel coated components have a short shelf-life (less than 24 hrs to meet solderability to Mil 893C specs!) unless protected over by gold. Issues also relate to the P content in EnP plating (Ref ENIG subsection). Storage conditions are important as is FIFO (first in/first out). Use within six months from date of manufacture remains a related concern with Ni. Copper bond wire-aluminum die pads The Cu-Al system is prone to various IMC failures similar to Au-Al system IMC growth in Cu-Al is lower than in the Au-Al system, and no Kirkendahl voiding is seen in Cu-Al IMC. Brittle CuAl2 in IMC layer lowers shear strength at 150-200˚C at 300-500˚C excessive IMC growth significantly reduces bond strength. Cu-Al IMC is impacted by atmospheric composition. Presence of O2 creates Cu oxides which inhibit bondability by growth of void like grooves under bond. Cl (chlorine) contamination

and H2O (moisture) can produce corrosion of the Al and Cu-Al IMC layer. Metallization and product positioning—real life examples Several diverse applications of COB-SMT are show in Figures 7 to 12. The Figure 7 PCBA is from a hand-held toy fan with motion activated flashing lights that sells for under US $4. Figure 8 shows the PCBA from a computer mouse selling around US $10. Both Figures 1 and 2, the products use a single-sided BT PCB with Cu OSP solder Pads and Ni over Cu COB pad metallization. Both products are low cost and low profile and made possible by COB-SMT with appropriate materials and metallization typical of products in this low end product category. At the next higher level of product hierarchy, a mid-priced product example, Figure 9, shows the COB in a personal digital assistant (PDA) using a multilayer FR 4 PCB with uniform Ni metallization at both soldering and wire bond sites with AlSi wire bonding process. Moving further up the ladder, Figure 10 is the display and control module from a microwave oven (with a US $100 product sales tag), and Figure 11 shows the main and remote control PCBAs from a mini -disk player. Both products use ENIG pads for both soldering and wire bonding. At the highest level, Figure 12 is the PCBA from a high-end heart rate monitor (a US $150 product) using ENIG at the solder sites and selectively plated soft pure gold at the COB sites. So far the author hasn’t encountered any real life examples using ENEPIG (electroless nickel, palladium, immersion gold)5 or DIG metallization, but that may be because both are relatively new. The common factor in each of the shown products is COB; however, metallization choices in each are dictated by product positioning, product life, reliability expectation and price point. The low end of the spectrum is very cost sensitive and uses metallization that leans in favor of the soldering process. Other examples (not shown here) relate to the IC industry, such as SiPs and MCMs. Common goals in integration. In the denouement, the goal for both IC packaging and the PCB assembler remains the same, that is, the ability to address the market demand with greater value add, increased performance & functionality while lowering cost.

Whichever way it is approached, attaching dies alongside SMT short cuts the final interconnection enabling functional integration with shorter time to market, PCB real estate savings and a slimmer form factor. Most COB applications involve (proprietary) ASICs (application specific integrated circuits), and the COB route provides a much shorter time to market and greater intellectual property protection so the ‘first to market’ can retain market leadership for a longer period. Conclusion COB merged with SMT is a very versatile process deployed currently across the very wide range of applications. That millions of products are being profitably produced and sold using COB is testimony of its robustness. Wire bonding is certainly not out of steam yet given the improvements seen in latest generation of bonders.6 The choice of metallization can help provide the right balance between wire bond reliability, soldering yields, and solder joint reliability. At the mid to low cost spectrum there is tendency to lean towards metallization aligned towards soldering process. Despite this compromise, the wire bonding process, for this product class, proves robust enough for the application. The required metallization for reliable wire bonding is not necessarily the same as that needed for high quality solder joints. In the case of ENIG (and its evolution, the ENEPIC (electroless nickel, palladium, immersion gold) process but limited to SAC alloy soldering) provided the nickel and gold plating control has been carefully maintained7-9 when combined with selective pure thick gold on the wire bond sites provides the highest reliability for both soldering and wire bonding but also incurs the highest cost. At the next lower level, ENIG is an option for both soldering and wire bonding without selective plating on the wire bonding sites. The ENIG metallization yields an excellent solder joint quality and while not ‘the’ best for wire bonding, it proves adequate for mid end product needs. At the low end where cost sensitivity is acute, either OSP over Cu for solderability with selective Ni or Au plating on the bond sites or simply a uniform Ni as a common soldering and bond site finish together with aluminum wedge bonding provides the lowest cost alternative. The target application, its reliability, life cycle, cost and price positioning must all be considered to obtain the optimum balance.

BGA assembly reliability—PWB quality is the key

BGA assembly reliability— PWB quality is the key Tom Clifford, TJB Associates The quality of the circuit board‘s pad is a critical factor in the reliability of the solder joint attaching the BGA. The solder-joints are hidden, and therefore the resultant BGA solder-joint quality cannot be easily visually verified, in contrast to conventional SMT constructions. This paper provides a gallery of photographs illustrating many types of defects, suggestions for acceptance thresholds, and a review of the consequences of defective BGA pads. Further, this paper discusses quality control protocols, sampling considerations, supplier interactions and inspection methods, all targeted to improve the durability and reliability of high-value electronics assemblies utilizing BGA-type connections. Keywords: BGA, Ball Grid Array, Pads, Defects

Introduction BGAs are rapidly becoming the dominant SMT high-performance package. BGA solder joints are critical to reliability and durability, but those solder-joints are essentially uninspectable because the solder balls/ joints are obscured under the package, This situation is similarly encountered with other hidden-joint constructions, including land grid arrays and QFNs. Defects of the pad can render the solder non-wettable, induce stress-risers and reduce the effective fillet area, etc., all jeopardizing performance and long-term reliability. The importance of inspection, outgoing from the fab as well as incoming by the user, is critical. These defects cannot typically be ruled out simply because a carefully selected sample or batch was selected for, and passed, some high-visibility “qualification” test protocol. These defects arise randomly, in different locations on a board, from board to board, and from lot to lot. Vigilance is necessary. Inspection protocols, at the fab and the user must accommodate appropriate sampling, performed by calibrated eyes, reinforced by real-time communication feedback. Further, the methods of inspection are critical. Magnification level, lighting, focus, clarity and image enhancement/capture are all pivotal parameters and must be defined and shared between supplier and user.

Even more important, the accept/reject threshold for each attribute must be clearly understood throughout the supply chain. The consequence, in terms of final product quality, of each level of each defect is often shrouded in crude “cause” data: e.g. “failure attributed to defective solderjoint”. This “defective solder joint” really failed because the plating popped loose from the PWB substrate, or the solder fillet was resting on a big caramelized resin goober, or a fiber acting as a stress-riser, etc. The user must determine the real root cause, and if it involves the PWB, he must share that with the fab/supplier. This paper does not dwell on the fab’s processes and likely causes of the pad defects. That is typically unknown by the user—irrelevant at that point—and is well known to and under the control of the fab. Note that technology evolves. New geometry, new solder alloys and new board platings and finishes will arise, as will defects that are not exactly those shown below. Nevertheless, the guidance contained herein should be mostly transferable. More importantly: the pace of shrinking geometries is inescapable. Fine pitch BGAs, flip-chips and waferlevel packaging for high-value assemblies will demand more fine-scale finesse in detection, discrimination and control. The paper provides the scope, then the

gallery of images with discussions, then QC reasonings and protocols with referee considerations. Scope This paper is primarily a photo-gallery of BGA pad defects, plus interpretations, consequences, and inspection advice. The acronym BGA (ball grid array) is used here to include the basic collapsing-ball plastic BGA as well as non-collapsing ball ceramic BGAs and column grid array constructions. Examples are shown from several board finishes, at pitches down to 0.4 mm (0.016”), but the criticality of a proper receiving pad, plus the reasonings and protocols are applicable to finer pitches, to other hidden-fillet constructions, to HDI bump pads and flip-chip substrates and to

other (increasingly ”green”) platings and finishes. Note also that the defects shown will also occur on pads for other SMT joints, with similar consequences. Those might be more inspectable, but many of these defects will result in compromised joints, even if visually apparently OK. These BGA pad images are offered in this paper because at this writing no industry standard is available to provide appropriate guidance. Defects Plating: surface condition or plating appearance The physical aspects of the pad, besides the size, are obviously important attributes. Lumps and dimples, for instance, can themselves compromise the integrity of the joint, and also can reveal internal weak-

nesses in the integrity of the pad’s plating which can cause further issues later. Figures 3 through 7 illustrate several types of defects, as well as their degrees of severity Figure 3 shows examples of the “awning” effect, where broken-off fragments of metal could get loose and cause electrical mischief. Figure 4 shows extreme edge-flaking. Figure 5 shows a case of a completely missing pad. Sad fact is that the BGA solder ball might stick to its trace long enough to pass a functional test, but would release/fail later in service. Figures 6 through 11 show other types of surface conditions caused during fab. Figure 6 shows “mouse-bites”, on the pad edge. Figure 7 shows dimples plus a double-level pad condition. Figure 8 shows a couple seriously compromised pads.

Figure 9 some sort of systematic massive damage or condition, eliminating the top of the pad. These conditions, at certain levels of severity, will compromise physical and electrical integrity, short or long term. External damage A damaged pad is clearly a concern. The impact depends on many factors, of course. Some damage (a scuffed HASL surface. for instance) might look dramatic but will reflow nicely with no ill effect). A scuffed silver plating can expose a troublesome base metal, subject to long-term failure. Images, interpretations, and communications are crucial. Figures 12 through 15 show examples of these situations. Figure 12 shows what looks like damage from a clumsy test-probe. Figure 13 shows some sort of deep linear gouge, and Figure 14 show damage that similarly exposes underlayers of base metal. Figure 15 shows a scuffed-surface situation, which might be rejectable. The point of this exhibit is the different appearance of the attribute depending on the lighting. A dramatically different image (in this example, plus a range of others not shown) is seen depending on side-lighting, intensity,

diffusion, polarization, etc. Are those light-on-dark, or dark-on-light? Are these black-on-copper, or white-on-gold? Acceptreject decisions might have been crafted naively to specify one or the other. The human eye/brain system can resolve the situation rationally, but AOI systems, or rigid defect-text language could be seriously misleading. Careful consideration of lighting subtleties is crucial for surface and color characterization, permanent-records and decision-making. Metallic contamination Usually the type of contamination can be identified visually, and the distinction between “metallic” and “non-metallic” can serve a useful purpose. Figures 1 and 16 through 18 show what looks to be metallic contamination, from process or tramp sources. These defects can be troublesome in two ways. They can upset the stencil-printing process by holding the stencil up off the board surface, which can impact solder volumes and registration. They can act as stand-offs at/during BGA placement, preventing or proper solder-fillet formation. More directly, in the extreme, they will compromise the mechanical strength and durability of the solder-joint. Figure 1 shows a large splash of a metal

or some material on the pad surface, leaving a probably non-wettable condition and likely compromised joint quality. Figure 16 shows a fairly common lump condition, which at this level is probably not rejectable. Figure 17, a tramp solder blob would probably negatively affect stenciling, but might reflow later with no appreciable ill effect. Figure 18 shows a hard metal point with probable impact on stenciling and solder-joint integrity. Non-metallic contamination This broad category can typically be sub-classified in terminology into specific defect types by appearance; and oftimes by supposed source or cause. However, these, and the other images in this paper, are presented solely as useful exhibits, with no pretense at a suggested terminology standard. In some fortuitous cases, polymeric contaminants will fall off in handling, or will be washed away in a board cleaning process. However, some cling fiercely, and will have their impact later in process or in service. Figures 19, 25 and 27 show some of the worst offenders: the resin (probably adhesive or maskant) will resist any likely bare-board cleaning process and will doubtless resist the flux/solder process, leaving very compromised solder

joints, good enough to squeak past final functional test before being deployed, as guaranteed early-failers, into service. Figures 20 and 22 show particulate FOD that might dislodge in handling, might be displaced by hot flux/solder, and might leave no deleterious reside; but why take a chance? Figure 26 and Figure 2 from the introduction, show unarguably rejectable conditions: solder-joints will form, if BGA placement isn’t disrupted, but will be seriously compromised, long term. Figure 21 shows a condition clearly originating in the plating process, which cannot be a good thing. Figure 23 is the author’s favorite: a QC stamp, doubtless signifying top quality, which is imprinted right on a soldering surface. Possibly the hot flux/ solder will remove it during assembly, but again, why risk it? Defects related to via-in-pad Unlike many of the FOD and point-defect conditions shown earlier, these VIP-related conditions are more systematic, are directly caused by the particular fab process, and will be recognizably similar in all BGA pads in that lot. That said, they will vary in severity, and acceptance thresholds must be established for new process qualification, routine

process control and final QC, Via-in-pad constructions and processes and materials are numerous, and the resulting reliability implications of the extremes examples are mostly uncharacterized. Deep open dimples can gobble solder, deep dimples full of chemical residue can pump unknowable materials into solder joints, bumps can impact stenciling, dimples and undulating pad contours can disrupt CTE-mismatched solder-fatigue shear planes and also trigger stress-riser situations. Thoughtful engineering considerations, backed by solid data, are necessary to establish proper acceptance thresholds, “Teaching” an AOI system to characterize dimples and lumps can be an interesting proposition. Solder mask defects The application of solder mask (design limits, materials, process control. QC, etc) has been a troublesome SMT challenge, particularly in recent times for BGAs. Figures 31 and 32 are clearly the result of an out-of control mask-application process. Figures 33 and 35 shows a very common and relatively minor case of an unintentional “solder-mask-defined” condition, related to bad registration and

Figure 20. ? something.

possibly inappropriate target dimensions and tolerances. Figure 34 shows a similar condition, made worse by a brittle condition, which leads to flakes of soldermaskant becoming FOD. Quality control reasonings and protocols The OEM—the name on the label—is responsible for the quality of the product. He must ensure that all the tiers in the supply-chain ladder do their respective quality assurance jobs: in-process during fab, at final at the fab, and at incoming by the user. A good baseline sampling view is that each fab batch is different, each board within that batch is different, each location and each pad on the board is different. A single sample-point is never enough. In every case, the inspection protocol sampling must be tailored, iteratively, to accommodate the type and distribution of defects likely to arise in the process as well as the actuals being encountered for that particular technology and design. Often the detection of a specific attribute can trigger a deeper sampling, to further characterize the severity and distribution of the attribute. Also, typically most point defects are rare; but rarity is slim comfort.

BGA assembly reliability—PWB quality is the key

One bad pad in a million (1 ppm) on a big, busy two-sided high-value board containing many big BGAs is a good predictor of one field failure in every few hundred boards. Not a good situation. Inspection finesse and training is key. The method depends on many factors, in addition to product volume and the value of the PWB. X-ray can deal with feature sizes and gross edge defects. All else must be dealt with optically, either visual aided by microscopy, or by patternrecognition video systems, “taught” by

visual calibration and establishment of accept-reject thresholds. Specific details and guidance depends on the defects being encountered. The acceptance threshold, (i.e. how severe is too severe?) is not necessarily the same for all similarappearing attributes, nor the same for all product families. Each situation deserves careful consideration. Note also that the appearance of many types of surface defects is profoundly influenced by the lighting: polarization, side-lighting, point vs. ring vs. diffused, focus, intensity, etc.

Simply specifying a “magnification level” is naive and inadequate. These factors, unless acknowledged and controlled, will trigger serious mis-interpretations, in both visual and optical/electronic methodologies. All this must be resolved and communicated effectively between the fab, the user, and any third-party lab or processor. Note that this paper—a gallery of images—does not dwell on the causes and corrections of these defects arising within the fab’s process. Typically the user need not care, and certainly cannot solve the

For new and/or borderline cases, engineering testing might be needed before accept/reject decision thresholds can be established and communicated.

Title Global business climate: most indicators point north

Walt Custer and Jon Custer-Topai

Growth “across the board” (relative to last year’s disaster) Forward-looking economic data are looking better and better. While we are not “out of the woods” yet, most global indicators support a broad 2010 recovery. Bloomberg’s Professional Global Confidence Index (Chart 1) and The Conference Board’s CEO Confidence Index (Chart 2) both finished 2009 on an optimistic note. Purchasing Managers’ indices for key industrial economies (Chart 3) also indicated that a global manufacturing upturn is well underway. Electronics equipment shipments were up 20% for Taiwan-listed OEMs in December 2009 vs. December 2008 and all other regions are headed back into growth modes (Chart 4). Yes, there will be a normal post-holiday seasonal downturn but its magnitude and duration should be muted (compared to last year’s disaster). Semiconductor shipment growth by region (Chart 5) has now either moved into positive territory or will do so shortly. Manufacturers of SEMI capital equipment (who had very difficult times in 2008 and 2009) are also now seeing increasing orders as their growth mirrors global semiconductor shipments (Chart 6).

Printed wiring board shipment growth (Chart 7) is similar to that of other members of the electronic food chain. All major regions are seeing PCB growth at or near “break even” levels vs. the same period a year earlier. In all cases we must remember that these growth figures are relative to a chasm in late 2008/early 2009 but at least our industry is expanding again. Chart 8 provides my colleague Ed Henderson’s most recent electronic equipment production growth forecast by region by year. Everything looks positive from 2010 to 2012.

Solar Manufacturing Products (tie) WINNER: KIC’s SunKIC with Spectrum KIC developed a very easy to use tool for the solar industry that has almost unlimited flexibility, so that it will continue to be productive for customers as they are changing the way they want to manufacture their solar cells in the future. One example is that the SunKIC will calculate “the area under the curve” for each profile. This may turn out to be a critical number. If yes, it will be calculated automatically. If no, the customer will not select that dimension, and hence it will not clutter the more important data. The SunKIC with Spectrum will optimize on conveyor speed allowing the manufacturers to run the fastest speed within the limitations of the process window and furnace capabilities. www.kicthermal.com WINNER: KIC’s e-Clipse TC attachment has a significant influence on the accuracy of the thermal profile readings, as well as their repeatability. The e-Clipse TC attachment fixture offers repeatable profile data, convenient TC attachment, and utilizes the user’s existing solar wafers. It features four spring loaded TCs within a lightweight fixture that also holds the solar wafer. The TCs have disk-shaped beads, rather than the traditional spherical shaped beads. These flattened TCs offer a more reliable contact to the surface of the solar wafer, as well as a greater number of repeatable profile readings. www.kicthermal.com

ALWAYS PERFECT JOINTS

Technology focus: The

rise of solder paste jet printing

In the face of a developing industry, screen printing using stencils is raising concerns. Long lead times, a lack of flexibility, printing errors and difficulty in coping with complex board designs have opened up a technology gap. Enter solder paste jet printing. As a software-controlled, stencilfree technology, jet printing has quickly established itself on the SMT market. It offers an unprecedented level of flexibility and a significant reduction in customer response times. Users have the ability to optimize solder paste deposits on every individual pcb pad. The result is improved solder joint quality and an ability to tackle difficult packages and the most complex board designs. In 2009, MYDATA’s solder paste jet printer (MY500) achieved 50% sales growth while the screen printer market fell by 63% (PROTEC). It seems that solder paste jet printing has come of age. But what is it about the technology that makes it a genuine alternative to conventional SMT stencil printing? The most obvious difference to screen printing is the fact that jet printing is stencil free. It offers an entirely new approach to solder paste printing for electronic circuit board assembly. A unique ejector mechanism travels over the board depositing solder paste droplets at extremely high speeds. Similar to an ink-jet printer, it is completely non-contact and is

entirely software driven. The software control and additional features provide users with unprecedented flexibility. Response times can be measured in minutes, rather than days. Jet printing is also able to meet increasing board complexity and highest quality demands, providing users with the ability to optimize solder paste deposits for every individual component pad on a PCB. Adding value in the production mix While jet printing has the flexibility to support a range of production set-ups, it is most effective in a high mix production environment. It is designed to keep pace with an assembly line running 30,000 components per hour. It is also capable of applying a wide range of leaded and leadfree solder pastes, as well as surface mount adhesives. In high volume production set-ups, it is well suited to in-line, add-on jet printing. Or it can be used in a secondary line for short-run and prototype production. Like all production-oriented sectors, the SMT industry is in a constant state of transition. Whatever the production mix, every manufacturer needs to respond to the challenges of a changing landscape. Three of the most important issues faced by today’s manufacturers include customer demands for quicker response times, improving solder joint quality and increasingly complex board designs. The

70 – Global SMT & Packaging – Celebrating 10 Years – February 2010

rise of solder paste jet printing can be linked to its impressive response to each of these issues. Meeting shorter response times “EMS companies are increasingly looking for flexible SMT equipment that is capable of handling the constantly changing product mix.” This comment from a spokesperson at the Fraunhofer Institute for Silicon technology ISIT in Germany is today echoed across the industry. Lead times associated with the ordering and delivery of stencils is measured in days. Lost stencils, cutting errors and last minute changes to layout all necessitate reordering. Cleaning between jobs also uses up valuable time. Jet printing provides greater responsiveness and an ability to switch between tasks more efficiently. Response times can be measured in hours. A new order can be taken in the morning and finished boards delivered the same day. With jet printing, CAD or Gerber data is imported off-line and used to prepare a new print job in a matter of minutes. Full software control also means last minute changes to board designs are quick and simple to implement. Jet printing is also well equipped to support lean manufacturing and just-intime production through the ‘intelligent’ use of information, a reduction in down time and elimination of non-value

Technology focus: The rise of solder paste jet printing

adding activities. In this respect, MY500 complements other MYDATA solutions that support lean manufacturing. Jet printing allows production to be broken down into smaller batch sizes to meet downstream production requirements without reducing machine utilization. And with changeovers taking less than a minute, manufacturers have the capability to produce emergency jobs and run prototypes with minimal disruption to ongoing production. Ensuring solder joint quality Solder joint quality is a key factor in ensuring the final quality of any printed circuit board assembly. Even within welladjusted processes, stencil printing is the most commonly cited cause of all soldering errors. One reason for this is that screen printing with stencils always requires a compromise between the optimal amounts of solder paste required by large components compared to smaller ones. While stepped stencils provide a certain degree of optimization, they do so at extra cost and with limitations regarding volume variation and minimum ‘keep out distances.’ In contrast, jet printing provides full control over solder paste application including three-dimensional printing (by dispensing paste droplets on top of each other). Default settings are provided based on CAD data. The user, however, has the freedom to fine-tune the volume, position, area coverage and height of solder paste for each individual pad, component or package on the PCB. This allows for optimized solder paste deposits on even the most complex and densely populated boards. For example, one customer uses jet

3D CAVITIES

www.globalsmt.net

printing for a product that carries 69 components on a square centimeter. Quality is further improved by the fact that it is a closed system. Jet printing significantly reduces the number of variable parameters, and, hence, the associated potential for human error, compared to stencil printing. Software control ensures that optimal printing is achieved extremely quickly. On-the-spot revisions to paste volumes can be affected in a matter of seconds. In addition, print programs are automatically stretched and aligned according to PCB fiducials. The noncontact technology also nullifies the effect of any board warpage. Supporting increasing complexity There is an unmistakable trend in the SMT industry toward miniaturized packages and complex board designs with higher component density. These types of challenging applications are a move away from the traditional strengths of screen printing technology. A fact recently reinforced in a report from the International Electronics Manufacturing Initiative (iNEMI), which stated, “Screen printing is reaching its limits when it comes to mixing technologies on a board.” With optimized solder paste volumes, jet printing can reliably handle difficult components such as QFNs and pin-in-paste components. At the same time, it also opens up new design opportunities. One example is the increasing use of cavities in three dimensional boards in order to reduce final assembly height. Jet printing is oftentimes the only automated solution capable of achieving this. Package on package designs represent another difficult challenge. Dipping

QFNs

PIN-IN-PASTE

components in flux or paste is both messy and operator intensive, and is rarely a satisfactory solution for higher volume production. Jet printing not only automates this process but can also compensate for any component warpage through the optimization of paste height and volume for each solder joint. An ability to handle difficult components and packages means the technology is ideally suited for use as an add-on jet printer, depositing solder paste onto previously screen-printed boards. This allows manufacturers to eliminate costly and time-consuming manual processes. Achieving return on investment Investment in new technology should be carefully matched to current and expected future needs. It is easy to over-invest in raw throughput capacity, ‘just in case’ it is needed. But if the entire production process is not set up to match that level of throughput, expensive equipment will be underutilized. Jet printing can help manufacturers to improve their overall production flow through greater flexibility, shorter set-up and changeover times and increased equipment utilization. It provides the ability to easily and consistently achieve high quality solder joints, even for demanding applications and complex board designs. Add to this a significant improvement in customer responsiveness and jet printing offers excellent potential for achieving an early return on investment. It is little wonder then that an increasing number of manufacturers are choosing to replace their out-dated screen printers with new jet printing technology.

Report: Meeting the technical and regulatory challenges of global environmental legislation

Report: Meeting

the technical and regulatory challenges of global environmental legislation

Nigel Burtt, Enjaybee Associates ERA Technology, now known as Cobham Technical Services, has been running an annual conference event in the UK concentrating on the effect of environmental regulation on the electronics industry since 1999. The two-day event organised at a hotel near London Heathrow airport held in late November 2009 was thus the tenth of its kind. The continuing demand for such a conference is a measure of the importance and influence of this subject matter. There were 18 presentations delivered on the current status of a variety of regulations originating mainly from the EU, such as REACH, RoHS, EuP and WEEE, but that are now being recognised in legislature elsewhere in world, such as in the USA and China. In November 2009, I attended, as a representative of both the International Association of Broadcast Manufacturers (IABM) and the SMART Group, an excellent two-day conference event on global environmental regulation organised by Cobham Technical Services, perhaps still better known formerly as ERA Technology. The conference was opened by Dr. Chris Robertson, one of the organisers, who began by comparing the mostly nascent environmental regulation ten years ago when ERA Technology first ran this event, with the status today. Back then, he said, the WEEE and RoHS Directives were still merely draft proposals, but the industry was already preparing to move over to lead-free solder in anticipation of enforcement and to promote a “green” brand image, the latter being an aspect which is still very important in guiding corporate attitudes to environmental issues. Where the EU in the 1990’s had

identified the need to tackle the waste stream created by the disposal of electrical and electronic equipment, Chris reminded us that product energy usage and efforts to tackle climate change were now the focus of much global political thought and it would be foolish to ignore this. The first presentation was given by Dr. Johan Nouwen, who works for the European Chemicals Agency (ECHA), the body responsible for the administration of the REACH regulation. Explaining the reasons and mechanisms behind REACH and the benefits claimed was something of a thankless task—especially given some of the comments on REACH in other presentations and during questions from delegates—but having someone from ECHA do so was illuminating. The complaint often voiced about the slow start-up by ECHA was partly answered by hearing that the IT systems they had put in place had been totally over-stretched as they had received 20 times more pre-

registrations than anticipated. In fact Dr Nouwen’s presentation noted that 2.75M pre-registration requests have been received for 143,000 different substances and from 65,000 different companies. This put the huge scale of REACH into stark perspective for me, as this is just the very start of its process. The second speaker was Dr. Phil Hope of the European Chemical Industry Council (Cefic), whose presentation looked at the interaction between the RoHS Directive and the REACH regulation. He was the first of many speakers to discuss the on-going work to “recast” the RoHS Directive. “Recasting” is a process in EU legislation allowing defined sections of a regulatory instrument to be amended, retaining the unchanged portions and repealing the old version entirely once the new text is agreed. The European Commission proposed and published recasts of both the RoHS and WEEE Directives in December 2008, and the

work since then has involved both the Environment Committee of the European Council and the European Parliament. The final texts need to be agreed as a co-decision process between these two. The original proposed recast Directive text called for no new restrictions, but did identify four substances for priority review and suggested that these and any further additions should be reviewed using the same methodology required by the REACH regulations. The MEP, Jill Evans, is the person responsible for drafting the proposed final text (the Council’s “rapporteur” for RoHS.) She agrees with those arguing that this recast should ensure new electronic equipment is free of all PVC and halogenated flame retardants and claims support for this from many consumer product manufacturers who, in turn, are being lobbied on this matter by public green pressure groups. In fact I discovered in writing this piece that she was speaking at an interesting conference, “Greening Consumer Electronics—from Hazardous Material to Sustainable Solutions” hosted at the European Parliament, the same day as we were meeting in London. Her intentions with regards to this were signalled even more clearly by a draft report she submitted to the Parliament in December 2009. Dr. Hope offered a summary of the position that Cefic had submitted in terms of both the recast ROHS Directive and the REACH regulation. They, in common with other industry bodies, supported the suggestion that future substance restrictions should be reviewed using procedures specified by the REACH regulation. Feodora von Franz then spoke, representing TechAmerica Europe, who are also in favour of alignment of RoHS with the procedural elements of REACH when reviewing substances. They have also made very strong representations that the very latest compromise text of the RoHS Directive, current at the time of the conference, where the scope has been expanded to include all EEE unless specifically excluded, was not at all acceptable unless subject to adequate assessment in advance with the involvement of all stakeholders. The next speaker discussed the Ecodesign Directive. Davide Minotti works for the UK government and has direct responsibility for this. An important recent change to EU legislation, he noted, was that the Energy Using Products Directive (EUP) was, as of October 2009, now known as the Energy Related Products

www.globalsmt.net

(ERP) Directive, having itself been subject also to a recast process. Some advice on practical steps for compliance with the Eco-design Directive was then given by Paul Ellis, of Kingfisher, a global DIY product retailer, whose presentation was centred on a real-life case study of Kingsfisher’s efforts which found that the voluntary phase-out period, prior to the relevant regulations being implemented, though supported by industry and encouraged by government, actually created more problems because they had to work with their supply chain without being able to point to fully defined product performance requirements. Next to speak to us was Georg Karl, presenting on behalf of COCIR, a medical equipment trade association. He gave a case study example of portable ultrasound equipment where voluntary product changes in progress were already expected to give environmental and financial benefits in advance of and better than the proposed EUP Directive implementing measures. Another case study presentation, this time concerned with the REACH regulation and its effect of the aerospace manufacturing industry, was given by Terry Palmer of Lockheed-Martin in the UK. He spoke of the special challenges for his industry that REACH presents with products that are required to have a lifetime of at least 25-30 years, fully traceable throughout to safety and airworthiness certification standards. Competing companies had co-operated in order to tackle these difficulties, via ADS in the UK, ASD in Europe and AIA in the USA. Together they had created two standards for the collection and verification of REACH data for the global aerospace industry and such was the seriousness of the business risks anticipated that this took just six months to develop and agree. He informed us that these organisations have produced a regularly updated guidance document for the industry which is free to download from their websites. In common with others who had already commented after the ECHA presentation, however, Terry’s case study showed that only 50% responses were received to initial supplier surveys on REACH. On a more positive note, 51% of those who did respond said they already had a compliance process in place and 44% provided additional helpful comments which aided understanding of the issues. Terry explained an escalation procedure that could be employed to

demonstrate due diligence if your supply chain won’t respond in time with the REACH data you need for tracing content of Substances of Very High Concern (SVHC): 1. Start with sub-tier suppliers first, then if they don’t respond; 2. Go up the supply chain to the next level, checking you have the correct supplier contact details each time and if possible establish the corporate REACH contact point in advance before submitting the query; 3. If the supply chain queries fail to provide the answers you need, thoroughly check all your own company history records, internal documents, data and resources held on the item; 4. Then check external resources (e.g. similar parts, substances, or suppliers); 5. Finally, consider testing the item in-house or using an external laboratory for the presence of SVHCs. One option open to the aerospace industry is if the substance or article is necessary for the purpose of a defence application, since the REACH regulation specifically allows Member States to grant an exemption in this case. It is however not mandatory for EU Member States to allow exemptions, nor to recognise an exemption from another Member State—Denmark, for example, had not found it necessary to grant any, thus far. This is a concern in such an industry which often requires international co-operation. The first speaker on day two of the conference was Iain Nichol, a UK government employee with lead responsibility for UK RoHS policy and part of the team working on the recast Directive. He also has responsibility for BIS policy related to the Eco-design Directive. Iain explained the latest status of negotiations on the RoHS Directive in meetings between the European Parliament and the Council. This recast was needed if only because of commitments in the original Directive to consider bringing product categories 8 and 9 (medical devices, and control and instrumentation equipment) within the scope of the Directive. These products were expected to be brought within scope without dissent; however the UK were arguing that the implementation dates for this, and other time-limited changes in the text, must alter and move further out, if the negotiations are protracted and delay the publishing date and final approval of the amended Directive.

Report: Meeting the technical and regulatory challenges of global environmental legislation

He gave us details of the “New Legislative Framework” (or NLF) which entered into force on January 1st 2010 and said that the recast RoHS Directive would be expected to adopt the approach and mechanisms laid down by this. The NLF also includes a “toolbox” of measures for conformity assessment, referred to as “Requirements for Accreditation and Market Surveillance” (RAMS.) The implementation of these measures is intended to increase the visibility of non-EU manufacturers and minimise the number of non-compliant products on sale. Chris Smith of the National Measurement Office (NMO) in the UK spoke next. NMO are the RoHS Directive enforcement body in the UK and would be using the NLF and RAMS. He explained that hand soldering with tin-lead solder remains the most common cause of noncompliance with the RoHS Directive, but NMO also often find evidence of fraudulent declarations or misinterpreted test reports. Chris cited an example of documentary evidence of compliance presented to NMO in the form of a test report that a company had commissioned but clearly never read, because the report clearly stated that the parts tested were non-compliant. NMO are also the UK body tasked with the enforcement of the Batteries Directive, which came into force in September 2008, and had just been appointed a few weeks beforehand as the body for the EUP/ERP Directive and the Energy Labelling Framework (ELF) Directive. Brian Spencer of OKI Europe then explained that their three main manufacturing facilities in Asia were able to claim officially that the printers they produce are “manufactured at a Carbon Zero facility” thanks to a validated CO2 emission offsetting project. Brian explained the work that OKI had done to meet and go beyond the requirements of global environmental regulation. The expenditure to meet this had been €2.5M in 2008 and was expected to rise to €3M this year. Julian Lageard of Intel pointed out that the EUP Directive actually states that in drafting implementing measures any existing industry voluntary agreements or codes of conduct must be considered if they may achieve the Directive’s objectives faster or at lesser expense than mandatory requirements. He gave an example of a current voluntary code of conduct being drawn up for IT Data Centres, which Intel were participating in.

Dae Young Park then provided advice concerning Asian regulations, explaining that China was currently issuing the most individual regulations of all countries in the world. However, he explained that this fact was misleading because one EU legal text might equate to 20-40 different Chinese pieces of related legislation to achieve the same ends. He compared the size of the REACH regulation at 278 pages with the current equivalent from China, which was just four pages long and had a much narrower scope. REACH, he said, was having a major impact on the amount of global chemical management policy being produced. Around 580 different chemical policies and regulations had been introduced in 2008, but again this data had to be qualified by seeing that 42% of these came just from EU Member States having to bring out or amend existing national legislation to comply with REACH. He showed that Japan, Korea, Taiwan and China were, however, producing chemical regulations that would have similar industrial influence to REACH. Dealing with China’s chemical control regulatory system is difficult even for Chinese domestic industry because around nine different government agencies are involved in producing and enforcing the legislation. The same multi-agency problem exists with China’s version of RoHS. The recent publication of the first draft of the so-called “China RoHS Catalogue of Products,” he said, came from one ministry only and appeared to be just “testing the water,” hence the relatively few products listed so far. He was sure that the list will be added to quickly and the number of affected product categories will increase if this first draft is successfully adopted. Jennifer Wallace, from a global environmental law practice, updated us on the progress of similar legislation in the USA, detailing existing state laws with similar intent to RoHS and noting that such laws were now being proposed at federal level. Recently, the HR2420 Federal Environmental Design of Electrical Equipment Act (EDEE) has been proposed. This is very akin to the RoHS Directive and aims to create a law which would prevent confusion and disparity between the various different RoHS-like State laws. EDEE is strongly supported the Association of Electrical and Medical Equipment Manufacturers. However, a timely reminder of the behind the scenes negotiations that may affect such regulation was made, in that the current text specifically exempts certain

74 – Global SMT & Packaging – Celebrating 10 Years – February 2010

medical equipment, so this body will be keen to have this exemption in place for its members, pre-empting any other law that may come later. Of course, this is happening just as the recast RoHS Directive looks set to bring medical equipment within its scope. Moving on to WEEE, she said that nearly 40 states have similar legislation enacted already or are in the process of doing so, but that federal law is being introduced too. Federal regulation similar to EUP/ERP was also in progress with one recent addition having some measures very similar to the EU’s Eco-design Directive, in relation to external power supplies and battery chargers. Stéphanie Zangl of the Öko Institut spoke to us about her organisation’s reviews of the RoHS exemptions on behalf of the EU. She admitted the granting and review process is very lengthy and bureaucratic. She hoped that the recast Directive would streamline the review, involving industry as early as possible to examine the practical aspects of removing an existing exemption or granting a new one. She also felt it was highly likely that the European Parliament would insist on adding restrictions for halogenated flame retardants and PVC to reduce the amount of this material ending up in the WEEE stream. Adrian Beard of Clariant looked at various industry projects in progress to allow us to move away from restricted halogenated types. REACH, the RoHS recast and consumer and market demand pressures will, of necessity, drive flame retardant manufacturers to produce newer and better types, he claimed. Dr Paul Goodman of Cobham Technical Services looked at various substances that were already banned or being considered for bans and what industry could use instead to replace them. One example he gave was Dibutyl phthalate (DBP), a widely used plasticiser. This is restricted in the USA and was on the REACH SVHC candidate list because it is classified as reproductive toxin. Many of the suggested substitutes were also being restricted, but some possibilities did exist, such as Tri-2-ethylhexl trimelliate (TOTM)—still classed as a lower grade reproductive toxin but already approved in the USA for medical product use. The conference was concluded by Dr. Chris Robertson who thanked all the participants and delegates and said that full conference proceedings would be available for purchase on the Cobham Technical Services website within the next few months.

Report: Microscan open day reveals a company on the fast track

Report:

Microscan open day reveals a company on the fast track

Just a few short miles over the Massachusetts border into New Hampshire is the North East Technology Center for the Renton, WA, headquartered vision systems company, Microscan. The new Technology Center was formally opened in a ceremony presided by company president Jeff Timms and guest of honor Andrew Wilson, editor of Vision Systems Design magazine. Indeed, editors from all of the leading US publications travelled to New Hampshire to join the Microscan team in celebrating the opening of the new center. Microscan has a long history in the barcode and automatic identification technology industry, and in 2008 expanded into machine vision industry with the acquisition of Siemens’ Machine Vision Business Unit. The acquisition occurred in late 2008 when the company was sold to Microscan. As a matter of note, Jeff Timms

was vice president and general manager of the Electronics Assembly Division of Siemens Energy and Automation until the end of 2007. Timms wasted no time in surrounding himself with a pool of talented people from the electronics and automation sectors. He recruited former competitors such as John Macrina (VP global sales), formerly director of Panasonic Factory Automation and Mark Regard (sales manager), formerly a general manager at Universal Instruments. He also brought some of his key people from the Siemens stable, including Al Silva (director of Latin America) and John Cooley (manager of strategic accounts). With this new talent, combined with the historical strength of Microscan, Timms set about to evaluate and focus on growth for the entire company. The strategic goal is to be to become a market leader in data acquisition and control solutions in the business verticals of life sciences, electronics and automotive. To help achieve this, Microscan set out to bolster the product portfolio to add software, middleware and networking solutions, in addition to maximizing the combined intellectual property and know-how to bring new hardware products and solutions to market. As part this, in addition to releasing 11 new products last year, they have developed a strategic alliance with Cogiscan to provide middleware and networking solutions to meet the track, trace and control needs of the entire factory floor. In 2009, while most companies were scaling back and seeking to protect themselves from the global economic downturn, Microscan was aggressively investing in R&D and creative application projects. The team includes 42 engineers, of which four hold Ph.Ds. The company has 85 patents and a further 30 in the pipeline. The demonstrated benefit of this decision was the release of 11 new products to the market in 2009. One key product line introduction

76 – Global SMT & Packaging – Celebrating 10 Years – February 2010

was the Hawk series of DPM products, which include the MINI Hawk, the QX-Hawk liquid lens full-function imager, and the Mobile Hawk highend handheld imager. In addition, the company released smart camera and GigE camera-based vision solutions with the industry-leading machine vision platform Visionscape®. Jonathan Ludlow Ph.D., product manager for Visionscape said all of Microscan’s smart cameras, frame grabbers and integrated systems used the same Visionscape platform, unlike their competitors. The smart camera has built-in communications (8 I/O’s), is networkable and is IP67 waterproof. The latest release, Visionscape 4.1, can digitize and transmit packets of images up to five megapixels over 100 meters. The Intellifind feature can locate the presence, orientation and read the component numbers in a barcode using edge location or fiducials. To summarize, Microscan is certainly one of the companies that is really hot right now. The company is planning some major new product launches at APEX in April. Make sure and add them to your list of “must-visit” companies at this year’s show. —Trevor Galbraith.

Title Interview

Interview—Fred Hume, Data I/O

Data I/O are a global supplier of device programmers probably best known for their Roadrunner product that fits into modern pick and place machines the same way a regular feeder does. Trevor Galbraith spoke to CEO Fred Hume at Productronica about how the company managed the economic downturn and what the future holds for Data I/O. The last 12 months have been particularly difficult for most capital equipment companies. How did Data I/O manage the downturn? We had an organization structure in 2008 that was appropriate for our revenue levels at the time, but knew we were top heavy with management for the lower levels of revenue that we could expect in 2009. So, we eliminated three vice president positions and reduced the number of outside directors from five to three. With fewer levels from the bottom to the top, we improved the flow of information and made faster decisions. That change reduced our breakeven. We also reduced our financial exposure by managing down inventories and receivables, which generated cash. We actually generated cash from operations throughout the downturn. Then we increased our investment in state-of-the-art development tools for our engineers. We implemented options to our

enterprise requirements planning system to provide better information for our sales force. We did not resort to mass layoffs. We did not cut working hours, and although we delayed scheduled salary increases, we did not cut salaries. We did not cut back on investment in the company’s key strategic initiatives; instead we increased it. We added people with critical skills, particularly in software, to strengthen our ability to execute our plans. I believe you also introduced a new grass roots strategy to educate your workforce. Can you explain this to our readers? We provided training to our employees on how to interview customers and particularly non-customers. Then we increased the amount of time our entire management team was in the field in front of customers. Every member of our management team (approximately 25%

78 – Global SMT & Packaging – Celebrating 10 Years – February 2010

of our total number of employees) from supervisor to vice president including purchasing, accounting, engineering, marketing, production, human resources, and administration with the possible exception of one or two individuals has been in the field calling on customers and non-customers so we understand the needs that we are meeting and those we aren’t. That information is shared widely within the organization and it guides our investment to ensure that we are meeting the customer needs today and into the future. Flashcore III is your latest programming platform. What are the theoretical and practical thresholds of this technology? We have a wonderful advantage with our FlashCore architecture. Its inherent design allows us to modify the design to use the latest FPGA technology while still retaining backward compatibility

Interview

with our installed base of thousands of algorithms and adapters. FlashCore III, our latest version provides the capability to program the latest NAND Flash devices in approximately one-tenth the time of FlashCore II. As devices get faster, we just upgrade the FlashCore hardware/firmware to stay ahead with the technology. Roadrunner has been Data I/O’s workhorse product for a number of years. What upgrades and changes have you made to keep up with modern pick and place systems? RoadRunner has been a wonderful product for us. As you know, it fits inside of the SMT equipment and operates “inside” the process window, unlike other after-placement programming solutions that don’t and therefore add time to the process and reduce manufacturing velocity. The physical appearance of the RoadRunner hasn’t changed much over the past ten years because the form has to fit inside of the placement machine. We have extended the line with versions to support the latest Fuji NXT and Siemens X-Series, as well as a new version for MyData machines. We introduced a large format version to support the very large microcontrollers used in automotive applications. Beneath the outside cover, the RoadRunner has been changed with the new FlashCore III programmer, the adjustable tape input module, and with improvements to the output transport belt to handle very small devices. What challenges are you facing from new devices coming into the market? One of our biggest challenges is keeping pace with the large number of bad-block management schemes that our customers need for the latest NAND-Flash devices. We now support more than one-hundred bad-block methods, probably more than any other firm. At what point does it become practical for an EMS company to move from manual programming to an automated system? If an EMS company is only programming a few thousand devices a year and is willing to live with inferior quality, then manual programming might be a viable alternative. The problem with this approach is that there are about 40 mistakes that can be made with manual programming from selecting the wrong data file to process errors that allow blank, defective, or mis-programmed parts to get onto circuit boards. This impacts yield at test and often field quality. The manual process provides

www.globalsmt.net

no easy way to track yield or other quality measures. Automated programming eliminates the process miscues that reduce yield and quality so scrap and rework are substantially lower. If a company is striving for very low DPMOs it needs to be using automated programming. And automated programming provides the burst programming capacity needed for rush jobs. There are many ICT test machines with a programming capability. Why do we need independent programmers? I love this question. Many companies program at ICT because they think it is “free,” since they are using existing equipment. Large data files, however, may take minutes to program at ICT, and that has a direct impact on manufacturing velocity. Programming then consumes a substantial amount of the ICT capacity and may become a bottleneck on the line. Management of bad-blocks for NANDFlash is particularly tricky for ICT and dynamic data such as serialization adds considerable complexity to the ICT software that has to be written. That complexity has to be supported over the product lifecycle by the internal test engineering department. So there are a lot of hidden costs with ICT programming. Using dedicated programming equipment eliminates the potential bottlenecks and the hidden costs. There are a number of programming houses that undertake contract programming. Why should manufacturers buy their own equipment versus using a contract house? Manufacturers that use contract programming typically carry one to two weeks of additional inventory float. That inventory is at-risk for code changes. The devices may have to be re-programmed if the code changes and if the one-timeprogrammable space has been already programmed the devices may have to be scrapped. The reduced ability to directly control the production flow with contract programming leads to increased safety stocks to buffer forecast uncertainties. So inventory with contract programming is often significantly higher than with programming in house on purchased equipment. Programming in-house allows manufacturing to be more responsive when code changes particularly when validation time is considered. Priorities are controlled locally. Code is also retained in house

minimizing the risk of intellectual property loss. Then, programming in house generally results in the lowest life-cycle cost. I believe you now offer a rental scheme. Can you explain how that works? We have offered rental programs for several years. The customer commits to a minimal rental period, typically a minimum of three months. They also purchase the consumables (mostly adapters) and algorithms as they are used and needed. It is a good program for EMS companies that may need capacity for a short-term contract. Data I/O has weathered the economic downturn better than most. What can we expect to see in the future? During the downturn we maintained our focus on three horizons of growth. As a public company we are evaluated by the market on quarterly performance, so we have to pay attention to it. But without a focus on the longer term we would fail to build long-term shareholder value. So we keep our sights on the intermediate one to two year term as well. Here we focus on the major new products we are developing that satisfy the needs of existing customers and those that take us into new market space. We also keep our eyes on the long-term, three years or more. That is the horizon where we take options on the future. This is the area of corporate development where we consider adjacent markets, explore the impact of emerging technologies, and where we consider acquisitions of technologies, product lines, or even other firms that could transform our business. We refused to let the economic downturn as severe as it was distract us from our intermediate and long-range goals. As a result, our plans remain intact and the company as one team together is executing on those plans. Our customers will reap the benefit of those investments in the form of new solutions for their business problems. That will ultimately return rewards to our shareholders and employees as well. Fred, many thanks for talking to us today. Trevor Galbraith.

The HA-/HA-s (highly accelerated whatevers), beware of the unstated caveats

Werner Engelmaier “The allure of quick results carries with it the danger of quick, but misleading.”

The HA-/HA-s (highly accelerated whatevers), beware of the unstated caveats I have been writing about accelerated testing of various kinds for a long time; in particular, about the difficulties of interpreting the results obtained with testing conditions much harsher than the actual operation conditions [Refs. 1-4]. Of course, I have not been the only one recognizing the problem [Refs. 5 & 6]. Recurrent issues with inappropriate accelerated testing that are brought to me by clients clearly indicate the need to reiterate the basic concepts of accelerated testing. Hopefully, this will serve to alleviate the misconceptions of what accelerated tests can and cannot do. Unfortunately, the allure of quick results, of getting ‘something for nothing,’ is too strong to eliminate the problem with “highly accelerated (HA)” tests which carry with them together with the promise of fast results the danger of results that are misleading. Traditionally, the functions of testing are of two quite different purposes: (1) to determine the reliability of a product (design) under the operating conditions expected, and (2) to screen out manufacturing anomalies that produce latent defects leading the premature failures during normal operation. The first purpose is best served using ‘Accelerated Reliability Testing,’ also referred to ‘Accelerated Life Testing’ (ALT). Properly carried out, the damage mechanism deemed responsible for anticipated product failures is accelerated by using the same but more severe loading conditions to reduce the test time for properly designed test vehicles. The second purpose is served by subjecting product with suspected latent

defects from inadequate manufacturing to loading conditions to precipitate failure in order for them to be detectable; this allows repairs and/or scraping of the affected product prior to shipping to the customer. The loading conditions for screening tests, often referred to ‘environmental stress screening’ (ESS), is typically not related to product operating conditions, but aimed at causing the latent defects to fail without significantly degrading good product. In the previous paragraphs terminology is used that had best be defined for proper understanding: • Failure Mode: The location, type and appearance of the failure. • Failure Mechanism: The physical process(es) producing the damage leading to failure, e.g., low-cycle fatigue (LCF), high-cycle fatigue (HCF), creep-fatigue, creep, overstress, conductive anodic filaments (CAF), ‘black pad,’ lack of solderability, insufficient wetting, etc. • Physics-of-Failure: The type, source and magnitude of loading that together with the active failure mechanism(s) is causing the failure. • Root Cause: The total information of design parameters, processing details and loading conditions leading to the failure mode(s), failure mechanism(s) and physicsof-failure observations that allow determination of solution options. It needs to be understood, that different failure mechanisms can produce identical failure modes; thus, having the same failure mode is not an indication that the same

80 – Global SMT & Packaging – Celebrating 10 Years – February 2010

failure mechanism caused the failure. Reliability testing, even accelerated life testing, takes a long time and lots of resources if properly done. This, of course, presents difficulties in keeping the product development cycles short, and puts tremendous pressure on engineers to produce answers—any answer, quickly. This led in the mid-1980’s to developments for “highly accelerated” tests [Refs. 7 & 8], which however were meant for qualification and screening purposes to identify defective components. Hobbs Engineering commercialized HALT around 1988 with testing regimens far beyond Rama Munikoti’s original concept at Northern Telecom. The purpose of many of these tests was to produce failures quickly, sometimes utilizing various step stress loading sequences, that then were used to make the product more “robust.” When I was a student at MIT, there was a contest to package a raw egg in such a way that it could be dropped three stories onto a marble floor without breaking. The winning designs certainly were very ‘robust,’ but there was no real need for this ‘robustness,’ nor would they have been commercially viable. Further, in many cases the HALT tests are so severe and unconnected to real use conditions, that failures are produced that are not pertinent to the reliability of the product, but cause significant confusion as to the actual meaning of them. The cracks in Figure 9 of last month’s column [Ref. 9] were produced in this fashion. This drive to often meaningless ‘robustness’ was—and still is—sufficiently alarming that industry documents were

The HA-/HA-s (highly accelerated whatevers), beware of the unstated caveats

produced to counsel for more appropriate testing [Refs. 10 & 11, see also Ref. 12] or even eliminating the need for such testing altogether with an up-front ‘Design for Reliability (DfR)’ [Ref. 13]. Unfortunately, the perceived need to produce test results and the ‘need’ for quick results has not diminished, and in many cases nowadays even reliability activities are outsourced without the necessary full attention on reliability issues by anybody [Ref. 14].

How do you expect to see business performing in your territory over the next 12 months? I think we are definitely through the worst of this recession, Etek’s range of customers are now almost back to full production equivalent to 2008. Our customers are starting to look at budget for new equipment in Q1 & Q2, 2010. This is really an exciting time to be involved in the European electronics industry. Some of our competitors did not make it through the hard times of 2009, which left a great opportunity to pick up both service & sales personnel to grow Etek’s technical team. Etek has also managed to position itself in 2009 to be prepared for the boom of 2010.

Mike Nelson

What are the technical trends in your industry? At Etek we are seeing a great deal of investment in new equipment starting in October 2009, mainly in AOI, cleaning, contamination testing, screen printing, fume extraction and x-ray. High reliability products have been the least affected during this downturn, but even our automotive and aviation customers are back with a bang....

How do you expect to see business performing in your territory over the next 12 months? This is hard to answer...I have visited many manufacturing companies in the last few months, some of whom are very busy and others are finding the current economic climate very challenging. However, our pick and place machines are ideally suited to the way in which UK manufacturing has gone in the past few years, so I believe that we are ideally placed to benefit from the market recovery in the SMT assembly business. Of course as well as manufacturing pick and place machines (Europlacer) and stencil printers (Speedprint), we are now becoming more generally accepted as a distributor of other compleAndy Jones mentary products within the market, from AOI, paste inspection, reflow (vapour phase and conventional) and on to new product lines that we are adding (selective soldering, PCB laser marking and barcode placement). What are the technical trends in your industry? In the last year, technical trends have taken a bit of a back seat in my experience. This year seems to have been a year of consolidation, with companies more interested in maximizing their existing capital investments, and to squeeze as much as possible without spending too much! That being said, there has been some movement toward inspection of product, and we have a great deal of interest in AOI.

www.globalsmt.net

How do you expect to see business performing in your territory over the next 12 months? We believe that the French market will be good in 2010 because for a few reasons. Since October, we’ve seen investments in the electronics industry coming back. The French government is helping smell to medium sized companies finance their investments through a dedicated public structure, OSEO. Subcontractors are seeing their order books increasing again, and they’re starting to have a medium-term view on their production plans. Finally, pick and place machines currently in production are usually seven to ten years old and need to be updated, particularly with the increase in use of 0201 components.

Alain-Michel Ceretti

What are the technical trends in your industry? Big volumes left France for low-cost countries. Today, customers need more “four wheel drive” equipment than Formula 1 machines. A contractor can’t afford refuse business because the volume is too low for his high-speed machine. Flexible machines covering 100% of the component range, including exotic applications, is THE key to surviving the PCB business right now. Small and medium companies will have to invest in AOI in 2010 to remain competitive.
