EDS Show doesn’t disappoint in new venue The Electronic Distribution Show or EDS, certainly didn’t disappoint anyone with its switch in venues this year. Hosted within the posh confines of the new Cosmopolitan Hotel and Casino (across the street from its former locale - Paris Hotel), this year’s EDS seemed to exude a little more energy. I’m not sure if it was the art deco vibe of the facility or a renewed hope vibrating within distribution circles?

“The industry relies on EDS to facilitate the goals they want to accomplish,” says Bob Willis, EDS vice-president and EVP/CTO, ECIA. “Our job is to provide the right venue and then get out of the way. The Cosmopolitan was the right venue and it provided a new level of excitement.”

“Every move to a new location has is unknowns and challenges,” added Bob Walsh, show president and president of Coakley, Boyd and Abbett. “We were pleasantly surprised at the professionalism of the Cosmopolitan staff and they met all of our challenges — resulting in one of our best EDS events.”

More than 3500 individuals represented 900 of the world’s top manufacturers of electronic components and their distributors and sales representatives at the meetings show – one of the industry’s longest running events. The emphasis at EDS is on forging and maintaining business relationships through scheduled, one-onone meetings, but the event is also filled with important product exhibits and networking opportunities. There’s no doubt that the spacious conference rooms with state-of-the-art technology made it a pleasure to do business.

Among the top-of-mind issues facing the electronics manufacturing supply chain included pending conflict minerals legislation.

Component makers and suppliers must be increasingly aware of the origin of the minerals such as tantalum, used primarily for the production of capacitors. Industry pundits believe this is one of the most significant government regulations to affect the industry since RoHS. Consumers want to know that component makers are not using tantalum from mines in eastern Congo, where more than 50% of mining sites are run by armed rebel groups illegally extorting and coercing civilians (and young children) to work in horrible conditions.

Counterfeit components continues to be another scourge belaboring the supply chain. Persistence of fake parts has even penetrated the US Military supply streams and forced US Congress to pass the National Defense Authorization Act. The act required the US department of defense to take action to detect and avoid counterfeit electronic parts.

In the end, buying customers of components want to know what these regulations mean and are about. As a result, it is expected that component representatives are educated and aware.

Canadian-born display technology takes intuitive to the next level

Endress+Hauser Canada donates $1.4-million to SAIT’s trades and technology complex

A new Canadian-born technology called ShadowSense from Mississauga ON-based Nytric/Baanto International Ltd. is being touted as the world’s largest and most intuitive multi-touch screen technology.

The new technology was literally on display for attendees to the Discovery 12 conference, showcased recently at the Metro Toronto Convention Centre.

“Shadowsense technology has the potential to lead advancements in multi-touch technology and ultimately change how consumers around the world see and use that technology,” says Dr. Tom Corr, president and CEO of Ontario Centres of Excellence (OCE), organizers of the event which provides a meaningful exchange for entrepreneurs and business mentors.

ShadowSense boasts a staggering 18 simultaneous touch inputs and unlike traditional touch technology that requires bare finger touch or a stylus, the technology intuitively recognizes almost any touch mechanism, says Av Utukuri, CTO and founder of Nytric and Baanto.

“It is a better and more cost-effective technology than any mid to large-size multitouch device currently on the market,” Utukuri says.

Nytric/Baanto have applied ShadowSense to what is believed to be the world’s largest multi-touch screen at a massive 193 x 72inches. In partnership with Christie Digital Systems USA Inc., the video wall is comprised of 32 Christie-brand MicroTiles, each of which is scalable, can be stacked or clustered to create custom shapes while maintaining full-motion.

“ShadowSense solves many of the technical shortcomings of existing touch technologies,” Utukuri adds. “By rethinking the traditional hardware and algorithms commonly used in optical touch solutions, we have created what we believe to be the most robust optical touch-sensing technology available today.”

west tech report

DDS looks to the ‘Cloud’ for continued success In Bill Gates’ “Business @ The Speed of Thought”, he writes that “the most meaningful way to differentiate your company from your competition ... is to do an outstanding job with information. How you gather, manage, and use information will determine whether you win or lose.”

For Digital Dispatch Systems (DDS) Inc., Richmond BC, they looked to the Cloud for a solution. It may not be a new trend, but Cloud Computing is dramatically and inevitably changing the way in which services and solutions West Tech are delivered to customers. Digital Dispatch is a global leader in providing Columnist, taxi fleet management solutions, having installed more than 80,000 mobile Sohail Kamal devices and 225 systems on four continents.

For companies that implement the cloud effectively, it allows for a faster time to market for applications and flexibility to deal with changes in business demand, which for anyone who has spent time waiting for a cab knows, is critical in the taxi industry.

DDS has introduced TaxiBook using Cloud infrastructure, which allows for scaled implementation depending on the number of taxis in a fleet. This reduces the startup costs for Taxi operators, allowing them to focus on business critical tasks such as growth. I recently had the chance to talk to Viji Maini, VP operations at DDS, about the firm’s recent success with its TaxiBook offering.

What product keeps DDS at the forefront of the fleet/taxi dispatch management?

With the introduction of TaxiBook, “DDS has utilized the same expertise and technology as used for our very large enterprise customers,” says Maini. Taxibook is a Cloud-based product that uses both DDS’s hardware and software for Taxi companies for dispatching, tracking and credit card payments. Maini explains, “This gives an extremely powerful, reliable and resilient solution for a fixed low price.” TaxiBook allows DDS to effectively manage the technology portion of customer’s operations so that customer can concentrate on managing their customers and drivers.

Gas Gauges Low-Dropout (LDO) Regulators Safety Devices

What is TaxiBook’s niche – what size companies does it serve?

“The TaxiBook product serves Taxi companies that are not interested in having IT infrastructure and IT services within their business structure. It is for cab companies that don’t have capital for investment or are startup companies,” explains Maini. “DDS has companies that started with 25 cars and have grown to over 100 on Taxibook - as the benefits of such a system are realized.” By harnessing Cloud Computing, DDS has been able to create a scalable solution that allows smaller operators to benefit from DDS’s products. The size of taxi companies can range from 5 to more than 250.

One of Canada’s leading process measurement and automation suppliers Endress+Hauser Canada is investing in the next generation of skilled workers by delivering a $1.4-million donation to the new SAIT Polytechnic Trades and Technology Complex in Calgary.

The donation will fund the Endress+Hauser Process Lab, which will provide state-ofthe-art training to students attending the prestigious SAIT’s MacPhail School of Energy.

The Lab is located in the Johnson-Cobbe Energy Centre, which is the West Wing of the new complex. It will be outfitted with the latest flow and interface measurement technologies, in addition to guided-wave radar instruments and nuclear density profiling systems. The company will also provide guest lecturers and various training materials that explain the different measurement technologies.

“Endress+Hauser has a long history of supporting the development and training of the industrial automation workforce,” says Richard Lewandowski, president of Endress+Hauser Canada. “Because of this culture, getting involved with SAIT was natural. By providing students with the best measurement equipment and training materials, we believe that we are in turn investing in our future employees.”

The labour shortage in this specialized trade coupled with the growing demand in the coming decade, make the donation and support of SAIT’s Trade and Technology Complex very timely, Lewandowski adds.

“Without the support of partners like Endress+Hauser we would not be able to provide such a first-class facility to our students,” says Mary MacDonald, Dean, MacPhail School of Energy. “We continue to be committed to providing state of the art technology and a skills-oriented education. SAIT has always been known as a trailblazer in research and innovation and we feel that this new facility is very reflective of that.”

Endress+Hauser has begun installation, commissioning and start-up of all instrumentation and systems in the lab. The company expects the facility, which is more than 1,800-square-feet, to be completed and operational by mid-August 2012.

What has helped a veteran OEM stay successful in a competitive global environment?

“DDS has been in the Taxi business for more than 25 years, with over 80,000 terminals installed and our products have grown to serve the particular needs of the Taxi business,” says Maini, who explains that their use of not just new technology, but improved manufacturing has helped sell terminals with greater functionality. “The Mobile data terminals used in TaxiBook are ruggedized and integrate seamlessly with Taxi meters and payment terminals.”

And DDS is hoping to avoid letting their recent success lead to complacency. Maini describes new features which include, “SMS Text Back to customers when their taxi arrives at their door, web-booking capabilities, iPhone booking capabilities and specific branded Gift Cards that can be used for Taxi rides.”

Semiconductors & ICs

Innovation, packaging and assembly in the semiconductor industry Being conservative will cost you in the long run

In

By Danny Hacohen, VP business development & marketing, RED Micro Wire

2011, worldwide semiconductor revenue was projected at $315-billion, a 5.1 percent increase from the 2010 revenue of $299-billion, according to Gartner, Inc. Consumer demand for 'gadgets' has given birth to new semiconductor applications and has largely been responsible for the overall industry growth. In such an expansive, high-demand, proven market, one would assume that the industry trend would be to further increase revenue by reducing costs. But are semiconductor companies really looking for more cost-effective solutions to meet market demand?

The semiconductor industry is historically very conservative, and in the

past years the packaging and assembly sector has seen little change and innovation. The semiconductor industry mindset stands in stark contrast with other aspects in the hi-tech industry where there is a persistent drive towards “faster, smaller, better,” where changing and being different is the name of the game.

The semiconductor packaging and assembly sectors tend to stick to the attitude of ‘slow and steady wins the race,’ which can be a very costly mindset.

In the semiconductor industry, quality, reliability and functionality are the key factors – cost-effectiveness, although widely acknowledged as very important, comes after. Innovation tends to focus on improving the silicon manufacturing process. Change and improvement in semiconductor packaging and assembly

The ramifications of the possibility of relaxed design rules are yet to be fully understood but are obviously far reaching. In addition, the wires themselves are highly scalable, opening additional possibilities of miniaturization.

For example, the move to copper bonding wire occurred because the prohibitive cost of gold wire drove the market to look for an alternative. Change occurred as a result of external pressures, not from an internal drive for improvement and change.

Delivering innovative technology to a new generation of programmers with the $35 Raspberry

Pi computer February 29, 2012 was a memorable Leap Day. Twitter, the BBC in the UK, and other news channels around the globe were literally buzzing about the imminent launch of the Raspberry Pi. The story behind this ‘second-by-second’ buzz of excitement was a small, low-cost but powerful computing device that would be a catalyst for a new generation of programmers, stimulating curiosity and sparks of innovation worldwide.

My phone was nearing meltdown. As a member of Premier Farnell’s element14 launch team, I was receiving calls, texts and tweets from professors, high school teachers, programmers, design engineers, and anyone else who simply loved the idea, congratulating us on the launch. The concept behind the Raspberry Pi that had captivated colleagues at the Raspberry Pi Foundation since October 2011, was a global hit! Demand was running at 700 orders per second and we were off to a flying start.

‘What makes the Raspberry Pi so popular?’ exclaimed many people in the subsequent hours and days after the launch. While

there is much technology commentary on the web on what was ‘the killer app’ for Raspberry Pi, I believe it’s the right mix of a few things that contribute to its success.

The Vision: Technology with a mission

By Bee Thakore, technical marketing, Newark/element14

runs Linux and is supported by Debian GNU/Linux, Fedora ARM, Arch Linux Operating Systems. It gathered much deserved momentum from the Linux developer community.

Broadcom was an early supporter of the Raspberry Pi program, and although not an ‘official’ sponsor, much of the technical work on the processor was carried out by Broadcom engineers. The chip featured on the Raspberry Pi is a special version and is aimed at allowing developers to port their own Operating System software, as well as for users to understand Linux Kernel sources. Broadcom also invested in the PCB design and production of the first 50 (alpha) prototype boards. The Raspberry Pi Model B is now available, and the Model A version without Ethernet is optimized for educational use and will be launching later this year.

On closer inspection, the pcb design of the Raspberry Pi is a piece of modern, tactile electronic art. In creating the pcb, Pete Lomas, trustee and vice president of engineering for Raspberry Pi, had to factor in complexity, high-performance parts and power densities in a small form factor with limited space. In an exclusive conversation with element14 on the eve of the Raspberry Pi launch, Lomas noted that one of the biggest challenges was escaping the 0.65mm BGA on a 6-layer board, while keeping good solid power and ground planes, as well as large (cost minimum) track and gap specs.

The inspiration for the Raspberry Pi single board computer (SBC) was ignited about five years ago from founder Eben Upton’s days as an academic Raspberry Pi computer board working in the Computer Science department at the University of Cambridge. He began to notice the applicants he was interviewing for degree courses didn’t really know enough about how computers worked, or they lacked a necessary level of programming skills. So he thought, “Could you design a product that would make computing more vibrant, more exciting and more accessible at a cost low enough for prospective students to buy it?”

A simple idea with a powerful vision.

Looking for inspiration, Upton recalled his own interest in programmable computing machines in the early 80s – the BBC Micro, ZX Spectrum and Commodore 64. When he thought about what they offered then and what was available today, he saw a gap in the market. The analogy was simple; we are A delicious name teaching people to read but are we teaching them Another interesting part of the story behind the to write?

Raspberry Pi is its name. According to Upton, the Upton started to work on this idea, and in 2006 trustees brainstormed for a short while and wanted to there were early concepts of the Raspberry Pi SBC build upon the tradition of naming computers after based on the Atmel ATmega644 microcontroller. As the versions iterated, Upton’s vision galvanized a continued on page 14 small group of academics, designers and computer enthusiasts, and the Raspberry Pi Foundation was born.

Irwin unveils new headquarters, signs Schlegel

CSC Intl merges with Sygnum Technologies

Electronic hardware distributor Irwin Industrial Ltd., officially unveiled its gleaming new headquarters in Aurora ON last month.

The 22,697-square-foot building includes a two-story sales and administrative portion along with a substantive warehouse area that will serve all the fulfillment requirements of its Ontario-based clients. Situated on 2.2-acres, the building was constructed with scalable design for future expansion to 40,000-sq. ft. The facility is located at 221 Don Hillock Drive in Aurora ON. Irwin also recently signed a sales agreement with Schlegel Electronic Materials (SEM) Inc., Rochester NY, leading supplier of EMI, RFI shielding, plus conductive tapes and adhesives.

Two Markham ON-based sales representative firms will meld their highly technical sales efforts into one as CSC has announced its plans to merge its operations with Sygnum Technologies Inc., provider of products and services to original equipment manufacturers (OEMs) through an engineering based approach.

The merger is designed to provide more product-focused coverage to the Canadian market, coast-to-coast,” according to Sygnum president Gerry Iuliano, “Collectively, our two sales organizations are now positioned to provide a broader and deeper CSC International and Sygnum range of products and services to meet our become one, Frank Sultana (on left) customer needs. The merger will provide scale and Gerry Iuliano announce the in addition to greater customer service and sup- merger of both their firms during the recent EDS Show in Las Vegas. port,” Iuliano says.

With a full complement of ‘double E’ technical sales personnel and a strong linecard comprised of semis, IP&E components, the newly merged companies, will be marketed under the name Canadian Sygnum Corp. or CSC. The sales group intends to extend beyond the typical reach of sales agencies, often delivering customizable engineering solutions, says CSC vice president Frank Sultana.

“We are enabling technology partners,” Sultana adds. “We’ve always been two firms that think outside-the-box and the merger of CSC and Sygnum exemplifies that.”

Irwin’s new headquarters is located on Don Hillock Drive in Aurora ON.

fruit and food such as Apple, Apricot and Acorn. The Pi then symbolizes a connection with Python.

The visual identity of the device has been its logo, which features the pcb and a Raspberry shaped as a buckyball with 32 faces, symbolizing a 32 bit device.

The visible 11 faces or segments of the Raspberry reflect the fact that it is based on the ARM 11 architecture. Similar to the collaboration provided on the element14 community, the Raspberry Pi logo design was crowdsourced from its community of supporters and developers.

Innovation is the freedom of creativity One of the best features of the Raspberry Pi is its simplicity. It’s about understanding the actual possibilities of what you’re able to do with a low cost, powerful, easy-to-use, and visually engaging computer. Raspberry Pi, in its stand-alone form, puts an end to the idea that computing devices are closed off and do not spur a desire to tinker, to change or explore different ways of using them. Users can engage the device with a number of different peripherals (monitor, adapters, keyboard, or mouse), giving them the option to fully build on the capabilities of the Raspberry Pi (see system map, pictured).

As of late April, the Raspberry Pi units are shipping and they have the potential to become a tool as powerful and versatile as the humble LEGO brick; this time equipping kids with the ability to imagine, program and code the future (in crystal clear HD quality).

Following the vein of food and fruit that is part of this story, I am hopeful that the Raspberry Pi, coupled with creativity and imagination, will sow the seeds for a new, comprehensive programming tool suite – a hardware/software programming paradigm that drives new collaboration and captures the hearts and minds of the next generation.

Precision photo chemical machining Production of metal parts with NO hard tooling or press required There’s an alternative method to produce precision parts today – PCM – Photo Chemical Machining also known as chemical blanking.

With the fastest response time and lowest photo tooling costs available, PCM is suitable for both prototyping and manufacturing medium / large production quantities of metal parts. Instead of stamping or laser cutting, PCM produces highly accurate and identical components for small and large batches. Chemical etching has no effect on magnetic properties or deformation whether internal stresses or thermal resulting a burr free component.

Virtually all aerospace, medical and electronics devices contain a precision metal part. Shimifrez was established 30 years ago specifically to manufacture high precision chemically etched components.

PCM provides precision custom-designed metal parts of any complexity and is very well suited to several applications covering almost every market segment including: medical and micro-electronic devices for which parts like EMI/RFI shielding, sieving and metal grids, nozzle heads and lead frames are required. In general this technology is particularly convenient on thicknesses between 0.01mm up to 1mm (0.0005” to 0.039”), when geometries are very complex, tolerances are very tight and time to prototyping and production is very short.

Process outline The PCM manufacturing process begins by cleaning the metal and coating it with a light-sensitive resist. The coated sheet is then exposed to ultra violet light through the photo master from both sides, hardening the photo resist where exposure takes place. The unexposed areas are developed away, thereby removing the resist and leaving the metal bare where etching will occur. Etching solution is sprayed under pressure onto the top and bottom surfaces, accurately producing the component by removing the unwanted metal. The resist is then removed to leave burr- and stress free precision components.

Precision Photo Etching Inexpensive and quickly-produced Photo tools, used in photo-chemical machining, replace conventional steel tools and dies. Photo tools can be generated in a matter of hours from a customer-supplied CAD drawing or data file.

Prototyping cycles can be reduced from weeks to days compared to hard tooling.

Flexible and fast From initial tooling to finished parts, the entire photo etching cycle can be completed in days. Given a normal backlog, typical lead times for new parts are 2-3 weeks. Often, repeat orders can be processed more quickly. Prototypes orders may be done in several days or even hours.

Consistent tolerances The photo tool is the foundation of accuracy. A photo tool is like a stencil.

Its only working exposure is to light. So there is no tool wear that needs to be

monitored. Dimensional tolerances are a function of the thickness of the material. Typically, dimensions can be held to ±10% of the thickness of the material.

Complexity made simple PCM can produce complex parts that would be either impossible or impractical to produce by stamping or laser cutting.

The etching process produces parts that are free of burrs and mechanical stress.

Investment upfront is very low since the cost of photo tooling is an order or two less than in competing technologies.

Material properties unaffected Chemical etching imparts no mechanical stresses on metal substrates. Where stamping, punching and die-cutting impart shearing deformation, and laser and waterjet cutting can leave ablative deformation, photo-chemical machining simply dissolves the unneeded metal, leaving a flat and burr-free part.

Materials Virtually all materials can be etched, although some are etched more easily than others. Etching is basically rapid, controlled corrosion. Thus corrosionresistant materials are difficult to etch and require extremely corrosive etchants.

However, many materials such stainless steels, beryllium copper, nickel alloys and brass, used commonly in manufacturing, can be etched readily by using aqueous solutions comprising ferric chloride.

Three-dimensional products Hand-foldable, etched bend channels are one of the unique features that Shimifrez can incorporate into a RFI/EMI shielding enclosure (board level shielding). Etched bend channels allows users to bend the sidewalls of a shield from a 2D flat part to a 3D finished shield, quickly and precisely. Bend channels can offer the designer several benefits such as the etched bend channels that are typically intended to create 90º right angle bends. They can also be used to create acute angle bends between 0º and 90º.

Or since the enclosure can be formed without the need for any traditional forming tooling, users can typically save hundreds of dollars in tooling and several days of delivery lead time for prototype and production needs.

Finally the etched bend channels exhibit a zero inside radii when formed.

Designers can save space on a board or the instrument by reducing the clearance necessary between the part and the components within it. This technique has been used successfully in many technical applications.

Intricate, thin PCM parts The resolution of etched parts depends on material thickness and thus the most intricate parts are fabricated from the thinnest materials. Photo etching has been the most general method for micro metal fabrication. This method needs a

By Hassan Nojoumi, president, Shimifrez Inc., Concord ON

masking process for the selective removal of material. As this method is based on a chemical reaction, undercuts or overcuts can be generated depending on the density of the chemical material and the duration of etching.

Electroforming Electroforming is a specialized process Shimifrez uses to produce precision metal parts that are 4 to 5 times more accurate in getting to tight tolerances than chemical etching. Electroforming is a metal forming process that grows metal through the electroplating process. The process creates an electroform piece through electro-deposition of a mandrel in a plating bath (nickel, gold or copper) onto a conductive patterned surface.

The electroformed part can be stripped off the mandrel, once the material is plated in the desired thickness. The electroforming process allows extreme precise duplication of the mandrel. This results in perfect process control, high quality production and very high repeatability. This makes electroforming perfect suitable for low cost production and high volumes.

The highly resolution of the conductive patterned substrate allows advanced geometries, tighter tolerances and higher edge definition. When requirements call for extreme tolerances, electroforming is very effective.

Compared to other metal forming processes like laser cutting, photo etching or stamping.

Precision products PCM has provided a major, rapidresponse service to supply components to the microelectronics, mechanical and electronic engineering industries over the past several decades. The demand has been for thin (< 1mm thick), complex, precision parts at an economic price. Leading examples can be items such as sieves and meshes, shims, washers, optical encoders and filters, EMI/RFI shielding enclosures (folded boxes), belts , sputtering and deposition masks to name a few.

Micro engineering products PCM is now also used to fabricate components used in micro systems technology and micro electro mechanical systems (MEMS), medical diagnostic equipment and biomedical engineering applications such as body nozzle heads, X-ray light choppers and grids to IC leed frames for semi conductors, gimbals and micro channels are some names to declare.

Aesthetic products In addition to the above, PCM can provide parts with intrinsic aesthetic value and is much used for the production of jewellery, signage or decorations and name plates. Very often, the etching process is combining with electroplating, anodising or painting processes to give additional colour and difference.

Pitfalls of counterfeit-part epidemic exposed Companies attempting to manage the growing challenge of counterfeit electronic components face a range of government- and industry-related pitfalls that make it virtually impossible to eliminate all risk associated with the plague of fake parts, according to experts speaking at the 2012 ERAI Executive Conference held in Las Vegas last month.

The event was co-hosted by IHS. Speaking to a sold-out crowd of more than 300 industry participants, presenters from information providers, standards organizations, defense contractors and distributors detailed the challenges associated with the rising tide of counterfeit and fraudulent devices. While much of the discussion focused on the impact of fake parts on the military/aerospace sector amid new defense department regulations, the presentations also examined the effect of counterfeits on the broader commercial electronic markets.

The scale of the counterfeit problem has grown dramatically in recent years, with reports of fake parts quadrupling from 2009 to 2011. Supply chain participants in 2011 reported 1,363 separate verified counterfeit-part incidents worldwide, a fourfold increase from 324 in 2009. Much of the counterfeit-parts problem can be traced back to the enormous amount of electronic waste (e-waste) generated each year, according to Bob Braasch, senior director, supply chain, for IHS. “People don’t hold onto their old electronic devices,” Braasch told the event attendees. “A three-year-old cellphone is ancient, so people are constantly upgrading to the latest device. As the world economy improves and as technology continues to develop, people increasingly will be looking for the latest technology. All of this electronics consumerism translates into e-waste.”

Braasch noted that 58% of e-waste generated by the US is shipped to developing countries. All too often, electronic components such as semiconductors are culled from this waste and then returned to the US and other developed countries in the form of counterfeit parts. As the number of counterfeit parts has grown, government regulations covering fake parts have grown more stringent. The US National Defense Authorization Act (NDAA), which was signed into law on Dec. 31, imposes strict regulations and severe criminal penalties on counterfeits supplied for government military and aerospace programs. While this phenomenon is impacting all electronics market, including consumer, communications and computing devices, much of the attention has been focused on defense, due to the NDAA.

Cadmium replacement coating targeted for MILAero connectors EN-PTFE composite coating exhibits equivalent, or better, properties than cadmium and nickel-cadmium

With the last remaining loopholes closing rapidly, the opportunity for connector manufacturers to find an optimum cadmium replacement is here. Even those that produce or distribute aerospace and military-grade connectors are under mounting pressure to meet the tightening requirements of the European RoHS directives, which are pushing towards elimination of cadmium altogether.

“The first European RoHS standard came out in 1996, but excluded the military and some aerospace applications,” says John Schnepf, president, Corsair Electrical Connectors Inc., Irvine CA. “Since then, however, the stance of RoHS against cadmium content in electrical and electronic equipment has continued to intensify. The EPA is not quite there as far as the requirements are concerned, but you can see the trend. It is coming.”

According to Schnepf, Corsair and other connector manufacturers are more than willing to eliminate cadmium or any other contaminants from products. The issue, however, is finding a suitable alternative

to cadmium and nickel-cadmium at a reasonable price point that delivers the equivalent (or better) conductivity, corrosion protection, compatibility, wear resistance, lubricity and low coefficient of friction.

“There are any number of platings that meet the corrosion resistance requirements of cadmium,” explains Schnepf.

“However, most do not meet the electrical requirements for conductivity, or meet the conductivity requirement, but not the corrosion resistance. A few of the more recent alternatives do well in both areas, but still do not meet RoHS standards due to use of Hexavalent Chrome and even Cyanide in the plating process.”

lubricity, wear resistance, conductivity, EMI shielding, and galvanic compatibility.

However, Cadmium is particularly dangerous when airborne in dust form. It can cause lung disease, kidney failure, and even death. Any maintenance process that releases cadmium into the air exposes personnel and the environment to this hazardous material. Furthermore, the Cadmium plating process often incorporates the use of cyanide in the process and Hexavalent Chromium as a sealant.

In 1993, cadmium became one of six hazardous substances restricted by Europe through its RoHS directive and the EPA has classified cadmium as a Group B1

compound (probable human carcinogen).

Since then, legislation in Europe and the United States has increasingly focused on banning and limiting the use of cadmium, along with other harmful substances. DOD, US dept of labor, RoHS and REACH policy all intend to restrict, control exposure or ban use of cadmium.

Connector manufacturers seek cad alternative To replace the cadmium content while maintaining conductivity and corrosion continued on page 24

Dangers of cadmium Cadmium, and in particular nickel-cadmium, can be electroplated relatively thinly and evenly on fine and coarse threads and complex geometries, making it ideal for use on connectors. Cadmium’s advantageous properties include excellent corrosion resistance even in salt atmospheres,

Cadmium replacement coating

continued from page 20

resistant properties, Corsair is working with CSL Inc. (Santa Clara, CA), a supplier that offers over 40 different plating processes. CSL is one of the few independent third party processors in the U.S. that develops proprietary custom coatings.

As a manufacturer specializing in circular connectors with crimp-removable contacts for military, commercial aircraft, and other aerospace applications, Corsair’s original specifications were MIL-C-26482 and MILC-5015. Today, however, the company is in the process of qualifying MIL-DTL-38999, one version of which is a circular connector with a cadmium-class finish.

The solution Corsair is currently testing is a nickel Teflon (EN-PTFE) composite coating developed by CSL over a decade ago.

This EN-PTFE composite coating is not to be confused with standard nickel Teflon plating which is available from multiple sources. A simple 1-2 layer of EN-PTFE will not suffice in harsh environments.

CSL’s EN-PTFE composite coating, on the other hand, forms a monolithic barrier that is self lubricating, scratch resistant, and anti-galling without galvanization.

CSL’s composite EN-PTFE coatings meet the conductivity and lubricity requirements of Cadmium while reportedly exceeding the wear resistance and corrosion protection attributes of Cadmium or Nickel Cadmium plating. It can cross mate with stainless steel, aluminum, PEI, and PEEK and can be applied to most metals and composites.

“We are currently investigating the composite nickel-PTFE alloy as an alternative to cadmium,” says Shnepf. “CSL has developed a plating process that apparently can deliver both electrical conduction and corrosion resistance and is RoHS compliant.” According to Shnepf, Corsair is currently entering the qualification phase of the testing with CSL. “Given that this coating meets all the performance characteristics outlined, we expect it will have a very favorable response in the military and aerospace market as a cad alternative,” adds Shnepf.

Connector manufacturers are not the only ones testing EN-PTFE. Over the past 15 years, Lockheed, Boeing, and Sikorsky have tested it and it is already a spec for connectors for harsh environments under MIL-DTL-38999. CSL’s EN-PTFE products are use on Navy ship programs, the F35 Joint Strike Fighter, Sikorsky helicopters, and Boeing Aerospace programs.

Standardizing on a cad alternative Standardization of product line features can be a major advantage for the connector industry from a manufacturing and marketing standpoint. As the military becomes more of an international collaboration, US connector manufacturers will have to become more responsive to RoHS and some of the other standards adopted by the European nations other NATO Alliance partners.

By standardizing on a replacement for cadmium plating embraced by both Europe and the US, connector manufacturers can enjoy manufacturing economies while making life easier for global distributors by simplifying inventories.
