FROM PIC16f877 TO PIC16f18877, TWENTy yEARs OF PIC EVOluTION author: lucio di Jasio, Microchip Technology INTRODUCTION the Pic16f877 microcontroller (Mcu) family was designed in 1997 as one of the very first flash microcontroller products from Microchip. it has been featured in countless projects, articles, books and blog posts in many languages around the world. twenty years later, the Pic16f877 is still in production and its product page is one of the most visited on the company web site! this is despite the availability of several newer generations of microcontrollers (with similar features) having been introduced on an almost regular cycle: Pic16f877a, Pic16f887, Pic16f1938 and eventually the Pic16f18877 model. clearly this is a testimony of the appreciation that embedded control designers have for Microchip’s “customer driven obsolescence” program. that program is the stated commitment not to end the life of any product that is selling. as long as orders are being placed for a device, even if only in minimal quantities, Microchip will continue to provide the device for customers. this is a great reassurance for those who have a working product and would prefer to spend their time and resources developing something new with the potential to generate additional revenue. While an old product cannot benefit from the latest advancements in innovative technology such as core independent Peripherals, a design team gains the freedom to manage the innovation cycle rather than being forced re-work the same product in an endless loop because their original part is no longer available. 6

PIN-TO-PIN AND BACKWARD COMPATIBIlITY if you did not already know about Microchip’s focused mandate on backward compatibility, then you’re in for a very pleasant surprise. as the newer generations of Pic microcontrollers continued to be released over the years, Microchip has ensured that its design teams provide pin-to-pin and even binary backward compatibility for previous generations of Pic devices. the extent of the efforts required to guarantee such a long term migration strategy are perhaps not obvious, but the fact that more than

BASIC fEATURES TABlE COMPARISON at this point you might be tempted to make the direct comparison between the datasheets of the two extremes of the time continuum: the Pic16f877 and its latest [re]incarnation, the Pic16f18877. incidentally at 660 pages the ‘18877 preliminary datasheet is almost triple the size of the ‘877 datasheet and is destined to grow larger as the full characterization data (graphs and charts) are added. but nobody has time to read datasheets anymore. Most will briefly gaze at the summary table, characteristically offered at the bottom of the first datasheet page:

table 1: Side-by-side comparison 250 diverse models exist of Pic microcontrollers (in a 40-pin package alone) that all fit in the same exact DiP socket - defined back in 1989 – should give you pause. that is commitment.

looking at table 1, the general increase in all kinds of memory sizes and in the number of peripherals present is obvious. flash memory has quadrupled, effectively filling up the entire addressable space 64 Kb of a Electronica Azi international | 5/2017


typical 8-bit architecture. raM memory has grown almost 10 times the size! While this is not according to Moore’s law, let me remind you that these are embedded devices, where robustness and power consumptions are much tighter constraints than the typical desktop Pc/consumer industry would demand. there is also an apparent explosion in the number of timers (and PWMs). timing is an important matter in embedded control where real time performance is valued more than the ability to process large amounts of data or computational performance. in fact, upon closer inspection of the datasheet, it is revealed that the new devices have a complex internal clock system comprised of as many as seven oscillators and two Pll circuits capable of producing accurate clock signals without use of any external components where the original devices had none. the newer devices can also execute code faster – almost doubling the speed – although, as we will see, MiPs figures can be deceiving. C lANGUAGE SUPPORT the greatly increased use of c programming language in the development of embedded applications can certainly be blamed for some of the growth in memory demand. to adapt to requirement changes over the past decade, the Pic architecture has changed under the hood. With the Pic16f1 series, new instructions have been added to the Pic core with the sole purpose of increasing its code density. they address the need to better support pointers and larger amounts of raM. Most notably the raM banking scheme for which the Pic is famously known - so handy for very compact assembly coding - has been paired with a more compiler friendly linear memory addressing. note that the old banking mechanism is still available and continues to guarantee backward compatibility for those legacy assembly applications. further, the new linear addressing scheme is unifying the data and program memory space of the Pic16f1. this allows for definition of large data tables in flash memory, unlimited size raM arrays and generic pointers. interestingly these major architectural changes have gone un-noticed to most c language Pic developers, after all this is exactly the kind of detail compilers were meant to abstract. this is one of the reasons why the MiPs figures of the old ‘877 microcontroller cannot

be compared directly anymore to the MiPs figures of the newer f1 cores in table 1. INTERRUPT ChANGES the other architectural element that has seen a significant improvement is the interrupt management system. While the newer Pic16f1 core maintains the original singlevector interrupt design, a new set of four shadow registers has been added to streamline the interrupt context save and restore sequences. listing 1 shows the traditional Pic16 prologue / epilogue: ; ISR: SWAPF CLRF MOVWF MOVF MOVWF CLRF


; Prologue

; ;(Interrupt Service Routine code here) ; MOVF PCLATH_TEMP, W ;Epilogue MOVWF PCLATH SWAPF STATUS_TEMP, W MOVWF STATUS SWAPF W_TEMP, F SWAPF W_TEMP, W listing 1: Prologue and epilogue sequence for interrupt context saving the standard interrupt prologue and epilogue used to take as many as 56 clock cycles. With the new Pic16f1 shadow register mechanism the need for the two sequences is completely eliminated and the cost of an interrupt is reduced to the basic four cycles required for the cPu branch. the result is a considerable increase in the microcontroller responsiveness or its real-time performance by as much as an order of magnitude. flEXIBIlITY careful observation at the bottom of table 1 reveals another interesting detail: the number of general purpose i/os available for the two devices is different despite the claimed pin to pin compatibility. it turns out that the new devices are multiplexing three more pins, previously reserved to a crystal oscillator and an external reset, which are now available optionally as a general purpose i/os. but only a deeper study of the datasheet will reveal the true golden nugget: All digital peripherals input/outputs are now multiplexed on each device pin! this feature

is known cryptically as Peripheral Pin select (PPs) and provides a quantum leap in flexibility to the Pic16f18877 devices and several similar Pic16f1 families. similarly the new Pic16f1 devices’ aDc module is now coupled with a [very] large analog input multiplexer that makes as many as 35 of the same pins available as possible analog inputs. this effectively means that each analog and/or digital signal directed to/from the microcontroller can now be routed optimally on the Pcb to control noise, increase robustness, simplify (speed up) layout and possibly reduce the number of layers and vias, ultimately helping to reduce cost. CORE INDEPENDENT PERIPhERAlS unfortunately the sole analysis of table 1, row by row, will never reveal the true game changing features found on the latest generation Pic16f1 devices. this is the presence of core independent Peripherals or ciPs for short. More than the individual peripherals’ features: sMt, Hlt, cWg, nco, clc … about which we could (and did) write entire books and the new datasheet spends most of the 400 additional pages – it is the design philosophy behind them that matters. the new peripherals are different because they are designed to be directly interconnected to each other and to perform autonomous functions, independently of the core. ciPs are meant to provide a hardware assist to the microcontroller to avoid the cPu bottlenecking of the system. When core independent Peripherals are connected among each other to perform a function, interrupts are not simply being executed faster, but rather they are completely removed from the application. the result is a more balanced design where configurable hardware efficiency and parallelism is matched by software flexibility. additionally, there are additional core independent Peripherals (not shown in the figure above) that are available on other Pic microcontrollers, allowing designers to pick the solution that best fits their needs. ROBUSTNESS a significant portion of the new hardware modules found on the Pic16f18877 is devoted to increasing the robustness of the microcontroller. the traditional watchdog circuit is replaced by a windowed system with a rich selection of scaling options. 7

EMBEDDED SYSTEMS the brown-out reset (bor) circuit has several thresholds, low-power modes and a dedicated crc scan circuit can be used to constantly monitor, in the background, the integrity of the memory content - without impacting the Mcu’s performance. lOW POWER While maintaining the ability to operate at 5V and drive even higher continuous currents on its i/os (up to 50ma), the electrical characteristics of the Pic16f18877 device tell us about much lower active power consumption figures (approximately by a factor of four) when operating over the entire voltage range (1.8V – 5.5V). the passive (stand-

tinuous and every application is connected! the most important feature of the newer Pic16f18877 devices might well be the availability of rapid development tools to automate and speed up the code generation by order of magnitude over what was possible before. the latest generation Pic microcontrollers are supported by MPlab® code configurator (or Mcc). this is a tool that can speed up the tedious process of initializing each device’s peripheral in minutes rather than hours, and some claim can eliminate entirely the need to read the datasheet (or at least a good portion of that time). further, a complete cloud-based toolchain, MPlab Xpress, is available to make the eval-

Every developer is empowered to decide if and when to revise an existing design or to simply maintain it as-is and focus instead on creating new products that can bring fresh new business opportunities / revenue. but when launching a new design, it is important to realize that by selecting the same trusted and true (popular) microcontroller model might mean missing out on a lot of new features and possibilities. the company consistency over the years and the obsessive commitment to [backward] compatibility might have had you believe that Pic microcontroller architectures have not changed much over the past

Intel® Compute Card a small-format PC Author: Mario Klug, Senior Marketing Manager, Embedded Boards & Systems

new designs in the it market are considered to be revolutionary if they enable new device concepts and applications that were previously either impossible or only possible to a limited extent in this new form. the ongoing miniaturization of chip designs and the resulting ever-increasing concentration of more and more computing performance in ever-shrinking spaces have been associated with new device concepts in the past that have heavily influenced the usability of computer systems. Whether one takes a tablet computer or smartphones as an example: these concepts first changed the consumer market before advancing into the industrial market in the next step, where they also opened up new ways of applying computer technology. However, all of these concepts involve completely new device classes that enable innovative application scenarios. looking at the approach to mobility in computer technology thus far, we can find various concepts that still coexist, but at best merely complement each other. When traveling on holidays, we tend to bring a tablet, which is complemented by a smartphone. in the work environment, notebooks, convertibles, or slimbooks are part of the standard repertoire. closer examination of a business trip quickly reveals different scenarios in which one needs to access computer technology and must therefore employ different concepts. When traveling by air, people sit in airport lounges and work on presentations on a 10

notebook while writing messages using the messaging services on a smartphone. When on board the aircraft itself, people are generally cut off from communicating with the outside world and continue using a laptop to prepare for meetings etc. on arrival at the destination, they must then connect the notebook to a projector or monitor for the presentation. the hotel room, on the other hand, is equipped with a more or less interactive television that connects via the hotel's Wlan with a tablet, notebook, and smartphone to allow us to carry out workrelated as well as personal tasks. one can therefore assume with a degree of certainty that most people always carry two to three different devices with them when they travel, and that these devices spend most of their time either switched off or running in power-save mode given the low average utilization across all devices.

UNIVERSAl SOlUTION fOR BUSINESS AND PERSONAl USE How much more practical would it be if just one computer replaced all these devices? one that can do virtually everything that the other devices can also do? one that is also as small and handy as a credit card, therefore not only saving space and weight, but also enabling greater utilization. this is precisely where the intel® compute card comes in: it is a fully-functional computer with external dimensions of 95 × 55 × 5 mm − roughly the size of a credit card −, a power consumption of below 10 W as well as a standardized interface that offers a completely new approach to mobile computing. it is clear that this concept is unlikely to catch on without a widely available eco-system. this is the very point where we need to consider the possibilities of this concept. as mentioned at the outset, designs previously classified as revolutionary were devices that functioned more or less out-of-the-box without any notable eco-system, and this

One for all

enabled them to gain acceptance quickly. this is not the case with the intel® compute card because the card requires docking facilities. assuming that the eco-system partners can make suitable devices available to coincide with the launch of the card and that these circulate rapidly in the market, the following scenario is conceivable: CARD INSTEAD Of ChAOS apart from a smartphone, the only thing you need to carry with you is the intel® compute card. You complete your final preparations the day before your departure via the docking station at your desk in the office. ideally, you simply insert the card into the card slot in the monitor. at the end of the day, you simply remove the card from the slot, put it in your bag, and set off on your trip the next morning. in the airport lounge, you insert the compute card into small monitors with compatible slots that are provided at the seats or in the restaurants and continue working until it's time to check in. on the aircraft itself, the entertainment system will ideally also have a slot for the card so that you can also continue working here. on arrival at your destination, you simply insert the card for the meeting and presentation into the slot on the monitor and give your presentation. the television set in your hotel room also has a compatible slot so that you can continue working on the big

COMPUTE CARDS monitor. What is the major difference to the now more commonplace docking stations designed for smartphones? Very simple: flexibility in the choice of operating system and applications used. With Microsoft continuum, the choice of software is limited by the processor platform and small number of smartphones available with Windows 10, while the docking concept by samsung for the galaxy s8 is tied to android. for the time being, the performance of smartphones is unlikely to be sufficient for emulations and VMs, which means in most cases that these concepts do not offer the required added value. the advantage consists solely of only having to carry one device around. this − at least up to now − has not been satisfactorily achieved. PERfECT PERfORMANCE, SPECIfIC SCAlING it's a different story with the compute card: the scaling of the celeron® n3450 all the way to the vPro™-enabled core™ i5-7Y57 enables performance to be adjusted to the majority of day-to-day applications. the interfaces provided via the docking connector enable the device manufacturers to connect both usb 3.0 host connections as well as Ethernet and up to two displays to the card, one of which can even be controlled at up to uHD resolution with 60Hz. as with the intel® bluetooth 4.2 and Wifi already integrated in the cards, this means that the interfaces required for the card to be used for the intended purpose in every docking system are available. However, use of the intel® compute card is not confined to the applications described in the specified scenario. the continuation of this concept, which intel® has already confirmed will include future processor generations, means that the compute card is also available for other applications that call for scalability, flexibility in the choice of operating system and programs used, as well as the possibility of easy upgrades to newer processor technology. one example is digital signage installations, most of which are currently realized by means of connected external Pc systems, oPs modules in the monitors or boards integrated in the system. Each of these concepts has its advantages and disadvantages. Disadvantages include the complex and interference-prone wiring of the external systems on the one hand, and the cost of upgrading the internal board to new technology on the other. this is why the

oPs concept was long expected to prevail. However it has proved to be too costly and complex to implement. although new approaches such as Mini oPs improve the solution in principle, they do nothing to change the rather poor availability in the market. assuming that the intel® compute card is available in sufficient numbers at market launch, the situation for applications in which robustness is not an essential − in which case external fanless box Pcs or fanless Mini oPs modules are the better choice − should be more positive.

COMPUTE CARD IN ThE IoT if we cast the net a little further to include everyday domestic appliances in our homes, interactive and networked televisions as well as interactive refrigerators would be the ideal candidates to use the intel® compute card. these appliances could also be upgraded to the latest processor technology and software after a few years. likewise, the compute card from work could be connected to the domestic television set, which would allow you to continue working on a large screen at home. naturally, you can already connect a tablet via HDMi to the television and use it as a monitor. but you are still restricted to the respective platform. if the development in the field of roll-up or folding olED screens continues to progress and if these types of concepts are brought to market maturity, there would also be no obstacles to the mobile use of the intel® compute card in conjunction with these types of display solutions. ultimately, the availability in the near future of an eco-system that is as diverse as possible will determine the success of this revolutionary design. in this context, rutronik is on hand to advise device and system manufacturers about developments - be it implementation in a new digital signage system or in the very latest high-end refrigerators. our colleagues on the ground are only too happy to advise you of the possibilities that the use of an intel® compute card in your application could provide.

18V Micro Dc/Dc 18V, 500ma synchronous step-Down Micro Dc/Dc converter at coDico

XCl225/26 series With an operating temperature range of up to +105°c and a quiescent current of only 12μa, this new 18V, 500ma buck Micro Dc/Dc from torEX is a welcome addition to the ever expanding range of ultra-small Micro Dc/Dcs from torEX! the Xcl225/26 series is a 1.2MHz synchronous step-down Micro Dc/Dc converter with integrated inductor in an ultra-small 3.0× 3.0×1.6mm Dfn3030-10b package. integration of the inductor simplifies the board layout and minimizes any unwanted radiated noise. a stable and efficient power supply circuit can be configured by simply adding only two ceramic capacitors externally thereby contributing to Pcb space saving and the shortening of development time. With a P-ch High side switch to ensure low voltage operation and 100% max duty ratio, the Xcl225/26 can operate from 3.0~18.0V and deliver loads up to 500ma making it an ideal replacement for inefficient linear regulators used in many industrial applications. output voltage is set externally within a range of 1.0~15.0V and the new Xcl225/26 is designed for very high efficiencies at low output loads. in addition, this new Micro Dc/Dc features low quiescent current (12 μa) and ultralow output ripple voltage. the Xcl225/26 includes over current and short-circuit 12

protection, adjustable soft start and a power good output. the operating ambient temperature range is -40°c~+105°c. Many traditional mid-voltage Dc/Dc converters use an n-ch MosfEt for the High side switch. Whilst an n-ch fEt is excellent for High speed switching it normally needs a special bootstrap circuit to drive it. a bootstrap circuit has the advantage of being simple and low cost, but it also has limitations. the duty-cycle and on time is limited by the requirement to refresh the charge in the bootstrap capacitor, which means the maximum duty ratio can never be 100% and this has implications when the input voltage goes below Vout. the Xcl225/26 uses a P-ch MosfEt for the High side switch that does not need a bootstrap circuit, so the maximum duty ratio can be 100%. this means that the output remains stable even when the input drops beneath Vout. the Xcl225/26 output follows the input when it goes below Vout and this can be important when the Vin source has a high impedance (i.e. due to a long cable). for more information, please contact our coDico regional sales Manager ivan Mitic.

Embedded and industrial computing applications are becoming smaller while offering more features with each new introduction. However, they still need to support legacy input/output (i/o) such as parallel ports 14

and even, in some cases, floppy Disk controllers (fDcs). these needs are addressed by super i/o controllers on the motherboard. a super i/o controller is a type of semiconductor chip, first used in

personal computer motherboards, that combines interfaces for a variety legacy i/o functions. these functions include a parallel port (commonly used for printers), serial port uarts, keyboard controller and Ps/2

ports for keyboard or mouse interfaces. in addition to these functions, super i/o controllers may also include some low-speed devices such as temperature, voltage and fan speed sensors, automatic fan speed control, infrared port controllers, watchdog timer and general Purpose input/output (gPio) pins. today’s super i/o devices use the low Pin count (lPc) bus for communication with the central processing unit. combining many functions in a single chip reduces the number of parts needed on a motherboard, thus reducing the cost of production. Microchip has introduced a family of feature-rich and flexible super i/o controllers, the scH322X family, customized to address the challenge of providing advanced functionality while meeting the space and cost constraints specific to your design. Each product in the family contains a different feature set, combining serial ports, parallel port, and Ps/2 with flexible gPio capability and world-class temperature and voltage monitoring to assist with developing more cost-effective industrial applications. Designed to operate with the x86 architecture, the scH322X family includes six devices tailored for different applications: the scH3221, scH3222, scH3223, scH3224, scH3226 and scH3227. some of the choices they offer include a varying number of serial ports, combined with hardware monitoring, and with and without keyboard controller functionality. the scH3227 is the most full-featured device in the family. it is a 3.3V super i/o controller with an lPc interface that operates from 19MHz to 33MHz to support legacy and the current x86-based architecture. the scH3227 includes a keyboard controller, hardware monitoring capabilities, power control logic and motherboard glue logic. the device also provides a parallel port, four full serial ports and the option for two additional 4-pin serial ports. the serial ports are fully functional ns16550compatible uarts that support data rates up to 1.5 Mbps. this device also offers hardware monitoring capability to track temperature, voltage and fan speed. this feature also provides programmable, automatic fan control. three fan tachometer inputs and three pulse-width modulator (PWM) fan control outputs are available. it has the ability to alert the system to out-of limit conditions and automatically control the speed of multiple fans in response. as illustrated in figure 1, the fans are used to monitor and control the temperature of the host processor, power supply and memory of the system. additional system related functionality is available via the 40 gPio control functions available with the scH3227. these gPios can serve as additional i/o ports, interrupt steering inputs, power lED outputs and even infrared pins. this next-generation family features smaller packages than previous super i/o devices. the scH3227 is available in a 144-Wfbga (9 × 9 mm) package and in commercial and industrial operating temperature versions. Devices in this family are also offered in area-efficient bga packages to further enable the most compact board designs. combining both legacy and advanced i/o functions in a single chip, these i/o controllers reduce the overall number of devices required to implement your design cost effectively.

tion and utilization, the Pt578 has built-in circuitry making it possible for the user to select if the power unit will be used in “single Mode” or “Parallel mode with droop current sharing.” this also reduces the number of products to keep in inventory as well the space used in the power rack. Depending on the application, the output protection may need a different type of configuration (switch off, Hiccup mode or constant current), which is one of the features included in the Pt578. based on firmware defined profiles and the output protection the mode of operation can be selected via a DiP switch with factory default settings though, in case of specific demand, it is possible to reconfigure any of the profiles at one of our PrbX configuration centers.

the unit also includes a Dc oK signal and a potential free relay contact for fault protection. a front lED indicates power unit status (oK or fault). When constant current mode selected, the Pt578 behaves as a current generator and is suitable for high capacitive loads, driving Dc motors, and as well an ideal solution to charge a second level battery backup for critical equipment such as navigation systems. Pt578 will operate with wide ac input voltages of 90 to 265Vac and with a Dc bus voltage of 125 to 375VDc. the input ac frequency is of 47-63Hz, and for naval airborne 440Hz with reduced Pfc. covering a large range of Marine applications, from sea to air, the Pt578 is specified to operate up to 10.000 feet and up to 30.000 feet in non-operating. two versions with adjustable output voltages are available in standard, 24VDc (23 to 29VDc) and 48VDc (47 – 56VDc) with an output power of 500W with peak power up to 750W during 10 seconds. Designed to meet international Marine requirements, the Pt578 complies with vibration specified in the DnV-gl table 7 High vibration strain, class b, ±1.6mm displacement, 2-25Hz, 4g; 25-100Hz (1 octave/ min). Protected by a conformal coating the Pt578 works in a humid environment of up to 100%, condensing at all relevant temperatures and meets the iEc60947-2 2kV, 60s. the product has an isolation of 3000Vac input to output and 2000Vac input to chassis. using high density integration building practice, the Pt578 is housed in a 132 × 67 × 128 mm (excluding the Din-rail mounting device) cassette-box, which is one of the most compact 500W power supply in its category, saving critical space in the power shelf to fit more functions per rail. the Pt578 also meets and complies with related chapters of the En61000-3 and -4, EMc Emissions En60945 conducted & radiated, conducted lf iEc60533 3VrMs, 50Hz-12kHz, EMc Directive 2014/30/Eu and DnV-gl temperature class D, -25 – +55°c; Humidity class b, up to 100%, condensing; Vibration class b, ±1.6mm displacement, 2-25Hz, 4g; 25-100Hz; EMc class b, class guiDElinE, DnVgl-cg0339, Edition november 2015.

rEnEsas ElEctronics EXPanDs 3D graPHics clustEr MarKEt to EntrY-class cars WitH r-car D3 sYstEM-on-cHiP renesas Electronics, a premier supplier of advanced semiconductor solutions, today announced its high-performance r-car D3 automotive infotainment system system-on-chip (soc), designed to expand the use of 3D graphics instrument clusters (3D clusters) that support 3D graphics displays in entry-class cars. the r-car D3 achieves both high-performance graphic capabilities and contributes to significant reduction in overall system development cost. the new soc includes a high-performance 3D graphics core that enables a high-quality 3D display and lower system costs equivalent to the bill of materials (boM) costs of developing with 2D graphics instrument clusters (2D clusters). by adopting the r-car D3, system developers can re-use their 3D graphics development assets, including software and graphics designs from high-end vehicles that adopt high-performance rcar H3 or r-car M3 socs to entry-level cars. this scalability enables development of easy-to-use and high visibility entry cluster 3D graphics at approximately the same level cost as the existing 2D clusters. in addition, renesas collaborates with industryleading partners in the instrument cluster field to further reduce development steps and costs. the increasing number of connections between the instrument cluster and the various sensors and control devices allows more information about the vehicle and its surroundings to be captured and displayed on the instrument cluster. However, this increases the need for improved visibility from a safety point of view. currently, entry-class vehicles feature mostly 7- to 10-inch liquid crystal displays (lcDs) that support mainly 2D graphics. in the

future, advancements in automotive lcDs size, resolution, and prices will support an anticipated explosive demand in 3D clusters to meet the growing need for clearer and highly visible designs on a large screen, particularly in the chinese market. in the meantime, system developers working with automotive instrument clusters must manage an increasing number of development steps and costs, as 3D clusters for entry-class cars are required to meet both the strict cost and high-performance as existing 2D clusters but with 3D graphics drawing requirements.

NEWS on sEMiconDuctor introDucEs WorlD’s first HigHlY scalablE faMilY of nEXt-gEnEration autoMotiVE iMagE sEnsors on semiconductor announced a cMos image sensor platform that brings new levels of performance and image quality to automotive applications such as aDas, mirror replacement, rear and surround view systems and autonomous driving. the HayabusatM platform features a ground-breaking 3.0-micron backside illuminated pixel design that delivers a charge capacity of 100,000 electrons, the highest in the industry, with other key automotive features such as simultaneous on-chip high dynamic range (HDr) with lED flicker mitigation (lfM), plus real-time functional safety and automotive grade qualification. the high charge capacity of this pixel design enables every device in the Hayabusa family to deliver super-Exposure capability, which results in 120-decibel (db) HDr images with lfM for high image fidelity in the most challenging scenes without sacrificing low-light sensitivity. the simultaneous HDr and lfM capability is especially important in enhancing safety as it ensures that all objects and potential hazards can be identified in both very dark and very bright areas of the scene. With the widespread use of lEDs for front and rear lighting as well as traffic signs, the lfM capability of the platform makes certain that pulsed light sources do not appear to flicker, which can lead to driver distraction or, in the case of front facing aDas, the misinterpretation of a scene by machine vision algorithms. the Hayabusa product family also features real-time, iso26262compliant functional safety capabilities to alert the system processor if the sensor has any issues or potential errors. these features enable system designs rated up to asil-c. the real-time capabili-

ty enables errors to be identified immediately rather than waiting for the full image to be transferred to the processor and then waiting for image analysis. this faster response time means the system processor can take immediate action to remedy the issue, which is crucial when considering that a vehicle moving on a freeway easily covers 100 feet in less than one second.

EFFICIENTly POWERING sENsORs IN IoT With the arrival of industry 4.0, cyberphysical systems, the internet of things and cloud computing have found their way into modern factories. operating as integrated communication networks, cyberphysical systems take decisions and act, while communicating in real-time with other systems as well as with humans. one of the main reasons for the rapid technological progress over the last few years is the drop in price of sensors of all types. only ten years ago, sensor technology was the preserve of highly specialised applications. today, sensors are a mass product. this development has made it possible to integrate more and more devices into networks where they combine, process and exchange ever larger volumes of data. However, every single sensor in such a network must be supplied with power â&#x20AC;&#x201C; be it through a central power supply, battery or energy harvesting devices.

figure 1: The R-78S boost switching regulator prolongs not only the service life of batteries in IoT applications but squeezes the last bit of power out of the cells. 28

Without sensors, there would be no internet of things (iot). they measure and record temperature, brightness, movement and many other parameters and transfer the data to the smart control devices. sensors however need power. although their power consumption is generally very low, they cannot work without it. Making sure that battery-operated sensors keep running for many years without any maintenance is quite a difficult task. this article describes how the service life of batteries can be significantly extended. The myth of the 3V coin battery Many iot and industry 4.0 applications run with 3V coin batteries, which are not only cheap but also very reliable. such batteries need however to be changed quite frequently. a fully charged cr2032 coin battery supplies approximately 3.2V. after only a few operating hours, the voltage drops however to below 3V, which might not be sufficient for certain wireless modules

(Wlan, bluetooth, loraWan, etc.). as a result, transmission can become unreliable or the signalling range might suddenly be limited. Extending the service life of batteries by using switching regulators the r-78s boost switching regulator from rEcoM (figure 1) has been specially developed for battery-powered iot devices. Electronica Azi international | 5/2017


the plug&play module provides a stable output of 3.3V from input voltages of as little as 0.65VDc to 3.15VDc, squeezing the last bit of energy from the battery cell. the r-78s thus enables users to run microprocessors, Wlan/bluetooth modules and iot systems with a single 1.5V battery or cell, which has a much longer service life

the capacitor charge drops below a certain limit, the circuit is briefly activated for recharging. this technology guarantees reliable, maintenance-free operation for periods of 10 years and more. as converters are affordable, the extra investment pays for itself in no time thanks to much lower battery and maintenance costs.

vise the machines and notify incoming interferences automatically to each other. they make use of predictive analytic models to trigger a corrective action. turning away from wires and batteries, these sensors could be supplied by micro generators (MEMs), which harvest energy of up to 4ma through environmental conditions, such as vibrations, heat, light, or temperature differences. this concept is called Energy scavenging or Energy Harvesting.

figure 3: In combination with an energy harvesting device the R-78S boost switching regulator provides a stable voltage to a sensor application. an r-78s from rEcoM is ideal to support the MEMs in providing a stable output voltage to the sensor application.

During these short times, the entire circuit consumes around 600µW. When not sending data, the circuit is in sleep mode. During these times, the r-78s is powered by a buffer capacitor and consumes only 7µa. if

Condition based maintenance condition-based maintenance is a system, which aims to provide information about a machines’ condition to conduct maintenance only if actually needed and falls in the category of predictive maintenance. to achieve this, typically many sensors are needed to communicate different types of signals. in future systems, intelligent sensors will super-

RECOM SWITChING REGUlATOR, 0.65 → 3.15V DC INPUT, 3.3V DC OUTPUT, 100MA the r-78s is a Dc-Dc boost converter designed to run from single cell batteries. the input voltage range of 0.65V-3.15V means that alkaline, nicd, niMH, zinc-carbon or lithium chemistry cells can be used to generate a stable 3.3 V output to power microprocessors, Wlan/bluetooth modules and iot systems. the high efficiency and low standby consumption can be used to extend battery lifetimes until the “last gasp” to get the maximum available energy out of the cell. the wide operating temperature of 40°c to +100°c, short circuit protection, otP, class a EMc and 3-year warranty round off this high performance converter.

Conclusion as the internet of things is really an internet of sensors, it depends on innovative power supply solutions. rEcoM offers intelligent components that help safe battery power with the r-78s boost switching regulator. these regulators squeeze the last bit of energy out of the battery, so that applications can be run for more than a decade without problems and no need for servicing.

SMT Productronica 2017: asM leads the way to the smart sMt factory

Many new solutions and eight integrated workflows under the motto “check-in to the smart factory”, technology leader asM assembly systems will present innovative solutions for all areas of modern electronics production at the 2017 Productronica trade show. With the company’s “Quick factory check”, visitors can compare the processes in their own plants with those in award-winning smart factories and identify the workflows that will have the greatest potential impact on costs, efficiency and quality. new products being rolled out include improved siPlacE tX high-speed placement modules and siPlacE placement heads, a new JEDEc tray feeder, and innovations like the asM Production Planner, offline Printer Programming, onboard Pcb inspection, touchless Placement, or siPlacE command center. With the HErMEs and aDaMos initiatives, asM also underscores its trailblazing role in open data integration and the industrial internet of things (iiot). asM will also show for the first time a complete solution chain for advanced packaging that enables electronics manufacturers to enter an attractive growth market. as a supplement to its booth at the Munich trade fair centre, asM will show off additional process innovations in the sMt center of competence at its Munich headquarters.

“standalone solutions for machines and lines, setup preparation areas, warehousing and other central operations in electronics plant block the way to the smart sMT factory. That’s why we decided to focus on eight core processes in electronics manufacturing at this year’s Productronica: four line workflows – planning, virtual production, process optimization, and production – and four factory workflows – material management, preparation, factory monitoring, and factory integration,” explains Gabriela Reckewerth, senior Director global Marketing.

Gabriela Reckewerth, senior Director global Marketing: “Productronica visitors can learn more about our broad spectrum of networked and integrated solutions that enable them to improve their processes and KPIs” “Productronica visitors can run our “Quick Factory Check” to analyze the status of process integration in their own plants before taking guided tours and visiting expert stations to learn more about our broad spectrum of networked and integrated solutions that enable them to improve their processes and KPIs.” 30

MORE flEXIBlE SIPlACE TX AND PlACEMENT hEADS Even the smartest factory needs powerful equipment. that’s why the asM booth will feature two sMt lines: one with siPlacE tX placement modules for high-volume applications like mobile phones, computers or lEDs, and one with siPlacE sX placement modules for high-mix applications with small lot sizes and frequent product changeovers. fIRST-hAND INfORMATION: Customers demonstrate optimized core processes smart, consistently optimized and heavily automated workflows provide the greatest efficiency benefits in modern electronics production. that’s why technology leader asM provides visitors of its booth with a process-oriented look at its extensive portfolio of solutions and its many innovations. in eight core processes, asM will demonstrate how the right combination of hardware of software can automate and improve processes. the focus will be on four line workflows (planning, virtual production, process optimization, and production run) and four factory workflows (material management, preparation, factory monitoring, and factory integration). as for another feature making it special, asM’s rolled out its “sMt smart network” last year, a global group of reference plants that work closely with asM’s experts to improve production processes and implement the smart sMt factory. reference of these smart reference plants will be present at the asM booth to convey first-hand information about their workflow solutions and their impact on their respective KPis.

AsM has rolled out its “sMT smart Network” last year, a global group of reference plants that work closely with AsM's experts to improve production processes and implement the smart sMT factory. INNOVATIONS fOR All PROCESSES for all eight workflows, asM will present innovations that make users’ processes more effective and efficient. two examples from workflow planning are the asM Production Planner and offline Printer Programming. With the asM Production Planner, users can import jobs from their ErP and MEs systems so that the setups can be scheduled and optimized across multiple lines with sicluster Multiline. With offline Printer Programming, users can create printing programs offline and store them in a central database

irrespective of specific lines and configurations. this reduces nonproductive preparation time on the line as well as program selection errors. before the programs are downloaded to the printer, the system checks automatically whether the printer’s equipment and configuration are suitable for the respective job. among other innovations being shown at the asM booth are asM remote smart factory, a comprehensive and secure solution for remote support, touchless Placement, a new process for placing highly sensitive components with a force of 0 n, and onboard Pcb inspection, a feature that inspects Pcbs for cleanliness and makes sure that solder pads were printed properly and previously placed components placed correctly before large components, bgas and shields are placed. OPEN AND READY fOR ThE fUTURE: Data integration with OIB, hERMES and ADAMOS With siPlacE oib as an open machine interface and HErMEs as an open and modern data standard and sMEMa successor for non-proprietary communication between line components, asM pursues a transparent data integration strategy on the shop floor. asM will also provide information about its participation in the aDaMos joint venture as well as its extensive activities in the iiot (industrial internet of things) field. aDaMos ag was founded in cooperation with other major technology companies like DMg Mori, software ag, Zeiss ag and Dürr ag to provide high-security cloud platforms and develop apps for industrial applications. the first results of these iiot activities will be demonstrated at Productronica in the form of mobile apps for monitoring asM machines. ADVANCED PACKAGING: Complete solution chain for a new growth market at another station, asM will provide information about advanced packaging, i.e. the assembly of chips into subsystems with combinations of bare dies, flip-chips and classic sMt components. asM’s experts expect many EMs companies to expand into this lucrative growth market over the coming months and years as it displaces the semiconductor industry’s classic wire-bonding in many areas. asM will demonstrate solutions for the complete process chain at the Productronica, starting with extremely demanding printing and bumping processes with DEK printers and DEK E-form stencils. at the heart of this process chain will be the extremely precise siPlacE ca with its combined placement of bare dies and flipchips directly from the wafer and sMt components from classic tapes. the placement process is followed by molding, singulation, testing and taping. With its orcas, laser 1205 and sunbird machines, asM backend solutions provides powerful and complementary equipment for these processes that has proven itself in many installations in the semiconductor industry. for more information about the Productronica program and the in-house events at asM headquarters in Munich, visit us online at Information about sIPlACE: Information about DEK: Information about AsMPT:



suitability of an enhanced low melting point alloy for a handheld device Current lead-free soldering temperatures can damage temperature sensitive components. Moreover they can cause a shift in the properties of some components which can impact the functionality of sensitive electronic devices. An easy way to solve this problem is to use a soldering alloy with a lower melting point that allows for lower soldering temperatures. Currently however these alloys have limitations in shock and vibration resistance. This case study investigates the suitability of the new enhanced lMPA™-Q alloy for a handheld high accuracy measuring device from the company Megger Instruments ltd in the uK.

By: Steven Teliszewski, technical sales Manager, Interflux® Electronics N.V. it is a well-known fact that current lead-free soldering temperatures can damage temperature sensitive components and even Pcb board materials. nearly every electronic unit has some critical components on it. these can for example be: capacitors, bgas, lgas, fuses, displays, crystal oscillators, lEDs, displays, components with a plastic body, coils and transformers ...

Figure 1: Megger’s electronic unit of a high accuracy hand held measuring device

Damage by thermal stress after soldering can in most cases be determined by either visual, optical, X-ray, ict or functional testing. it is a less-known fact that current lead-free soldering temperatures can also cause a shift in the properties of some components which can impact the functionality of sensitive electronic circuits like e.g. measuring devices. these kind of failures are often harder to determine. an easy way to solve problems related to too high soldering temperatures is to use a soldering alloy that has a lower melting point. lower melting points allow for lower soldering temperatures. currently however these alloys have limitations in mechanical strength. shock and vibration resistance tend to be the weakest points. this limits the field of use of these alloys. the lMPa™-Q low melting point alloy has been specifically developed to overcome these limitations. this case study investigates the suitability of the lMPa™-Q alloy for a handheld high accuracy measuring device from the company Megger instruments ltd in the uK. this device is currently being soldered with an snag3cu0,5 alloy and is sensitive to the heat in the soldering processes. furthermore the device needs to be shock resistant in the field. ASSEMBlY Of ThE ElECTRONIC UNIT the electronic unit consists of a double sided i-ag finished Pcb board with sMD and through hole components. the temperature sensitivity mainly lies in the different capacitors on the board that are all somehow affected by heat. the boards are printed with the DP 5600 lMPa™-Q solder paste with rol0 classification. the units are reflow soldered in a full convection oven without nitrogen and with a profile with a peak temperature below 205°c. this reflow profile will indulge the t°-sensitive components. the through hole components are being soldered with lMPa™-Q solder wire.

Figure 2: Reflow profile for LMPA™-Q 32

VIBRATION AND ShOCK RESISTANCE TESTING Handheld devices need to have good shock resistance in the field. in the past this particular property has proven to be the weak point of traditional low melting point alloys. Hence, the suitability of lMPa™-Q alloy for this device will be tested accordingly. Electronica Azi international | 5/2017


the electronic unit is submitted to vibration and shock resistance testing according to the test standards described in bs En 60945 and bs En 60068. for objectivity purposes, the test are performed by a third party specialized testing lab. the Half sine shock test will perform shocks in both directions of all three axes. shocks will last 11ms with a peak acceleration of 30g or defined by practical limitations of the test setup. in this case, the shock in the X-axis was limited to 10g due to breaking off of the measuring sensor with higher peak accelerations. shocks in Y and Zaxis were at 30g. as a reference, 10g is equal to 4 times the shock a mobile phone experiences when dropping from 1 m on a concrete floor. the vibration test will start with a resonance frequency search on the electronic device in all 3 axes. the resonance frequency for a device is this frequency on which it experiences the highest forces. it is different for each single device and also for each axis. a 2H vibration endurance test with a peak acceleration of 3g will be performed on the found resonance frequency. if no resonance frequency is found, a standardized endurance frequency of 30Hz will be used with a peak acceleration of 3g. in this case, only for the X-axis a resonance frequency of 82.92Hz was found.

from these results can be concluded that the lMPa™-Q alloy has sufficient mechanical strength for handheld devices. However, to get a better idea how the lMPa™-Q holds up against the snag3cu0,5 alloy, comparative vibration endurance tests were started up. comparative shock testing is more difficult due to the previously mentioned limitations of the test setup. shock and vibration resistance tend to go hand in hand as vibration actually is a Figure 5: SAC solder joint failure fast sequence of shocks. SAC305 vs lMPA™-Q 30min X-axis vibration endurance Test sequence frequency Acceleration lMPA™-Q SAC 305 1 30Hz 18g Pass Pass 2 30Hz 20g Pass Pass 3 30Hz 21g Pass Pass 4 30Hz 22g Pass Pass 5 50Hz 25g Pass fail Table 1: sAC fails first in comparative vibration testing the same handheld high accuracy measuring device was chosen for this test. Electronic units soldered with snag3cu0,5 and lMPa™-Q were provided to the test lab as vibration in the X-axis is expected to be more critical, it was chosen as the only axis for this comparative test. a standard test frequency of 30Hz in combination with a peak acceleration of 18g was used as an initial setting for a 30min vibration endurance. after visual inspection, the acceleration or frequency was stepwise increased, until a first failure was noticed. the first failure manifested itself on an electronic unit soldered with the snag3cu0,5 alloy at a frequency of 50Hz and a peak acceleration of 25g.

Figure 3: Vibration & shock testing

RESUlTS AND CONClUSION as the lMPa™-Q alloy passes the required shock and vibration tests and the snag3cu0,5 alloy fails first in comparative vibration testing, the lMPa™-Q alloy is suitable for the production of Megger’s handheld high accuracy measuring device. the lMPa™-Q alloy allows for lower soldering temperatures in the soldering processes and temperature sensitive components are less affected by heat. this results in a more reliable production process and higher quality of the electronic device. based upon the good results, Megger instruments ltd has started the procedure to homologate the lMPa™-Q alloy for more processes and products.

MicrocarE EXPErt EDucatEs tHE ElEctronics inDustrY on oPtiMiZing bEncHtoP clEaning Removing contamination from printed circuit boards remains a huge reliability and warranty issue for PCB manufacturers. One of the cleaning experts from MicroCare Corp., the industry’s leading manufacturer of critical cleaning products, addressed that specific issue at the Texas Cleaning and Reliability Workshops in Austin and Dallas on Oct. 23rd and 25th, 2017. russell claybrook, regional sales manager for Microcare, stated that process control remains a major deficiency in the cleaning of Pcbs, whether it be on the benchtop or in an automated cleaning system. With more than 27 years of experience working in the industry, claybrook has expertise in both Pcb assembly and rework. He presented methods and tools for creating an effective ‘Process control Program’ for Pcb cleaning. “Bench top cleaning still is performed with the same methods companies used 40 or 50 years ago,” he explained. “It’s ironic that manufacturers devote enormous amounts of energy and capital into process control at printing, placement and reflow, only to abandon that discipline at the bench − the final assembly area most circuit boards pass through before shipping to end users.”

method really is being called into question.” “Any cleaning process should be defined with a specific quantity of cleaning materials for each cleaning task,” he added. “Furthermore, the process must stress the four steps for successful cleaning: wet, scrub, rinse and dry” cited in “to Kill a circuit board: Perils in Manual soldering and cleaning Process” by cheryl tulkoff. this paper was a major resource for claybrook’s presentation. originally Presented at sMtai 2014 in chicago, Ms. tulkoff wrote: “Manual soldering and cleaning processes are among the least controlled processes in printed circuit board assembly. as a result, they create special challenges to both quality and long term reliability. “if flux residues must be removed manually,

a four step process of wet, scrub, rinse, and dry is recommended. use some form of dispensing system for the solvent to control the flow and volume,” Ms. tulkoff concludes in her paper. the workshop gave Microcare the opportunity to push this message forward and to share its expertise on the best cleaning methods for the industry. for automated cleaning, Microcare recommends vapor degreasing processes using a modern, environmentallyprogressive low-boiling solvent. on the benchtop, the best method is a controlled dispensing systems such as the triggergrip™ system, which attaches onto an aerosol and delivers faster, better and safer cleaning, which costs less and cleans better than sloppy dip-and-brush cleaning.

“The workshops were great for bringing together local circuit board assemblers, with cleaning experts from across our industry in an educational forum,” claybrook added. “It provided me with an opportunity to share ideas for writing a PCB cleaning process while showing some of the tools MicroCare can offer for quantifying materials used in that process.” the symposiums were well attended with about 100 registered participants. the richardson (Dallas) workshop included attendees from across the spectrum of electronics and semiconductor manufacturing. Engineers and experts from Elbit systems, fujitsu, Qorvo semiconductor, raytheon and many others participated. “’Dip-and-brush’ cleaning has been the de facto standard for PCB cleaning for years,” russell explained. “But with today’s new solvents, new PCB designs, new component configurations, new fluxes and pastes, the efficacy and cost-effectiveness of this old-fashioned

Through hole wetting on an osP finished Pcb in a lead-free selective soldering process Although, the OsP finish possesses some very interesting properties, it is seen by many as a low cost solution for low cost electronics. The main reason for this is that the solderability of the OsP coating degrades quite quickly after a lead-free reflow process. This can result in problematic through hole wetting in wave and selective soldering. This case study focusses on finding the limitations of an OsP coating in terms of through hole wetting in a selective soldering process with two different lead-free alloys. A standard snCu based alloy and the new enhanced low melting point alloy lMPA™-Q.

By: Steven Teliszewski, technical sales Manager, Interflux® Electronics N.V. the ever increasing packaging density on Pcb boards and the changeover to leadfree alloys have played a major role in the evolution and choice of Pcb board finishes. the correct choice of a Pcb finish usually involves the assessment of the pros and contras that are inherent to each finish and in most cases depends on the application and its requirements. these requirements can for example be: mechanical strength of the solder joint, planarity of the finish, pollution of the solder bath, storage time, degradation of the finish after reflow and last but not least cost. Despite its limitations in planarity, the Hal finish has succeeded to maintain a fairly wide acceptance on most markets. also niau has established itself as a reliable finish, although au pollution in the solder bath or solder joint might be of concern to some. Where i-sn appears to be more popular in Europe, i-ag seems to have the preference in the americas. the osP- finish is being used quite a lot in asia but has less acceptance in the rest of the world. although, the osP finish possesses some very interesting properties, it is seen by many as a low cost solution for low cost electronics. the main reason for this is that the solderability of the osP coating degrades quite quickly after a lead-free reflow process. this can result in problematic through hole wetting in wave and selective soldering. beside this disadvantage however, the coating has very interesting properties. the application process of osP in Pcb manufacturing is easy and has little impact on the solder mask, it has very high planarity, good 38

storage stability and it is cheaper than all the other finishes. this case study focusses on finding the limitations of an osP coating in terms of through hole wetting in a selective soldering process with two different leadfree alloys. a standard sncu based alloy and the low melting point alloy lMPa™-Q TEST SETUP a double sided fr 4 board with an osP coating commonly used in asia was chosen as a test board.

• time between ageing in reflow and selective soldering is 48 hours. in practice, osP degradation is sometimes already witnessed after 4 hours. • an sn finished DDr3 connector was chosen because of its high pin density of 240 pins with a 2 mm pitch. this will allow for enough results to assess the through hole wetting performance. a secondary difficulty for this connector is bridging but this was not the scope of this case study. a DDr3 connector is often used in computer technology for board to board connections. • selective soldering tests will be performed on a Kurtz Ersa Ecoselect 1 machine with a standard sncu based alloy and the low melting point lMPa™-Q alloy.

Figure 1: OSP test board with DDR3 connector • the test board has through holes for a DDr3 connector that are connected to cu-mass planes on both sides of the board for a more realistic thermal behavior. • the boards will be soldered in three different conditions: fresh, two times aged with a reflow profile with peak temperature of 200°c and two times aged with a reflow profile with peak temperature of 240°c. • the reflow profile of 200°c will simulate the ageing of the osP coating when submitted to a double sided reflow process with an lMPa™-Q solder paste. • the reflow profile of 240°c will simulate the ageing of the osP coating when submitted to a double sided reflow process with a standard lead-free solder paste.

Figure 2: Kurtz Ersa Ecoselect 1 • a 14 mm nozzle allows to solder the connector in one stroke. the wettable nitrogen flooded nozzle provides for stable and repeatable soldering conditions. • the water based selective soldering flux selectif 2040 was used for all boards. • lower preheating temperatures compared to wave soldering are sometimes used in Electronica Azi international | 5/2017


selective soldering in combination with higher soldering temperatures to gain process time. a preheating temperature of 80°c measured on the top side of the Pcb board will be used for all boards. • the test will start with a soldering temperature of 285°c for both alloys. this is a common soldering temperature for selective soldering with standard lead-free alloys. the soldering temperature will be stepwise reduced. • for each soldering temperature the soldering speed will be stepwise increased starting from 5mm/s.

have consistently worse through hole filling performance than the boards aged with a peak of 200°c • there is hardly any difference between the through hole filling performance of the fresh boards and the boards aged at a peak of 200°c. • furthermore, signs of non wetting of the osP on the solder side are nearly only witnessed on the boards aged with a peak of 240°c. • the lMPa™-Q alloy has better through hole wetting performance than a standard sncu based alloy at similar settings. this result is anticipated because of the lower melting point of the lMPa™-Q alloy and hence bigger thermal process window.

TEST RESUlTS AND DISCUSSION • all boards are visually inspected under a microscope and by X-ray. • through hole wetting performance is CONClUSION divided into 4 categories: the degradation of osP after reflow is influ1) + means that the barrels are filled with a enced by the peak temperature of the filet to the top side of the through hole. reflow profile. a standard lead-free reflow 2) 100% means that barrels are filled without profile has drastically more impact on a filet to the top side of the through hole. through hole wetting and non wetting than a 3) -100% means that the barrels are filled in low melting point reflow profile. boards between 70% and 100% aged with an lMPa™-Q reflow profile 4) - 70% means that the barrels are filled achieved nearly the same soldering results less than 70% than boards that were not aged.

* First signs of non wetting of the OSP on solder side of the PCB • in the table with the soldering results, signs of partial non wetting of the osP on the solder side of the through holes are marked with a red asterisk (*). • the results clearly show a difference between the boards aged with a standard lead-free reflow profile and the boards aged with a reflow profile for the low melting point alloy lMPa™-Q. • the boards aged with a peak of 240°c

using low melting point alloys can eliminate the degradation problem of osP and facilitate the overall use of this finish. a secondary conclusion is that the lMPa™Q alloy allows for lower soldering temperatures and faster soldering speeds to get good soldering results. this can substantially increase the throughput capacity of selective soldering machines.
