Tin whiskers cause problems

Wednesday, February 1st, 2012

Tin whiskers” is not an imaginative, fanciful term for some aspect of electronics manufacturing.Tin whiskers are real, and they pose a serious problem for electronics of all types. Tin whiskers can could cause short circuits. The switch to alternative solders (away from traditional tin+lead solder) in order to achieve RoHS compliance has created some challenges for the semiconductor industry, especially tin whiskers.

Understanding and mitigating tin whiskers article says that tin whiskers are almost invisible to the human eye and are 10 to 100 times thinner than a human hair. They can bridge fairly large distances between electrical device leads, and in so doing, can short out the conductors. They can grow fairly rapidly; incubation can range from days to years.

Toyota has had problems with uncontrolled acceleration. Earlier report have said that the acceleration problems that led to the recall of nearly eight million Toyota cars and trucks in 2009 and 2010 were mechanical. Yet some believe that the issue goes beyond the floor mats and some new material on that has just surfaced. Toyota accelerations revisited—hanging by a (tin) whisker article tells that a NASA paper delivered at the International Tin Whisker Symposium last year reported on tin whisker growth in Toyota accelerator pedal position sensors that could lead to unintended acceleration. The whiskers were found in a “failed” sensor from a 2003 Camry and at least two other similar units that did not malfunction. The NASA paper gives further insight by detailing tin whisker physical behavior as well as outlining guidelines and methods of detecting whiskers.

Understanding and mitigating tin whiskers paper tells that tin whiskers are real, and they pose a serious problem for electronics of all types. Connectors, passive and active components, switches, and relays now must all be lead-free, and the switch to alternative solders in order to achieve RoHS compliance has created some challenges for the semiconductor industry, especially tin whiskers. Pure, tin-plated electronics have become ubiquitous over just the past five years. When used as a finish material for electronic components, pure tin can spontaneously grow conductive whiskers.

When a whisker grows between two conductors, the whisker usually fuses (disappears), creating a momentary short circuit. In some cases the whisker forms a conductive path, creating false signals at an incorrect location. In very rare cases, rather than disappearing like a fuse link, the whisker can instead form a conductive plasma.

Because the electronics industry does not really know what causes tin whiskers, cannot predict their appearance other than to say whiskers are likely to form on pure tin. Also higher the altitude, the more rapid the whisker formation.

Here are some suggestions for reducing the risk of tin whiskers:
1. Do not use pure tin. Studies have shown that alloying tin with a second metal reduces the propensity for whisker growth. (minimum of 3% lead by weight is acceptable)
2. Do not rely on the order paperwork. Use x-ray fluorescence (XRF) to verify finish on all critical parts.
3. Refinish a pure tin-finished part with a hot-solder dip. Stripping and replating is a recommended approach and is a service offered by some of the original part manufacturers.
4. Use some type of encapsulation or conformal coating. Uralane 5750 conformal can provide some benefit by reducing the growth rate, but tin whiskers can grow through conformal coating.

The shift away from lead solder presents risks for high-reliability applications, particularly in the form of tin whiskers on tin-containing finishes. When a tin-bearing finish is used, conformal coatings have been somewhat effective in fighting this problem. Because of the potentially dangerous and unpredictable risks of pure tin, it is not presently used in medical devices.

NASA has lost satellites due tin whisker. NASA Tin Whisker (and Other Metal Whisker) Homepage has more details on that. Tin Whiskers in Electronics Components white paper from Tyco Electronics is also good reading with lots of pictures.

Home electronics is expected to become a new status symbol (Kodinelektroniikasta uusi statussymboli) article tells that consumer electronics demand will increase further in 2012 according to market research by Deloitte. Latest digital technology will also become a status symbol in homes. In particular, tablets, and smartphones Deloitte expects record sales.

Mobile phones with advanced features start to replace traditional separate devices for different functions. This is happening for small digital cameras and video cameras. 2012 At the end of 2012 there is the more navigation capable mobile phones than the stand-alone GPS navigators according to Berg Insight. Berg Insight calculates that the sales of separate GPS navigators started to decline already in 2011. Nav equipment manufacturers have responded to the situation by bringing the software to mobile devices.

How apps for your appliances represent the next opportunity article tells that Samsung Electronics not only pushed its smart TVs at CES, but a whole line of smart appliances, including washers and refrigerators. If Samsung Electronics is right, developers may flock to smart appliances as the next opportunity. That included music apps such as Pandora on the refrigerator and an app on the washer that can ping you when a load is done.

IPv6 is becoming more important. One of the driving forces behind the move from IPv4 to IPv6 has been low-cost embedded devices, which are going online at an accelerating pace. Support for this technology will be crucial for the success of many forthcoming connected embedded devices. IPv6 on a microcontroller article gives some tips how to implement IPv6 on small microcontroller.

The science fiction future of medical implants is here article tells that semiconductor solutions contained in hand-held consumer product innovations are now finding their way into medical implantables: wireless data and power transmission as well as analog, microcontrollers and transducer capabilities.

App Servers and Lua Scripting Speed Rich Web Applications for Small Devices article tells that with ever more smart devices connecting to the web, even small embedded devices must be able to serve up rich graphical presentations of the data to satisfy user expectations. This creates a new challenge for designers of small embedded systems as a new task. With time and space at a premium, a scripting approach can be invaluable. LAMP (Linux, Apache, mysql, PHP) setups work well in full-up web server implementations (at least around 65 Mbyte of memory), but for small embedded system we need something that uses less resources. Smartphones have set the bar ridiculously high when it comes to how sophisticated the application interface should be.

We’re on the cusp of an era that offers better-than-ever display technologies for an excitingly immersive viewer experience. Just as we’ve seen the emergence of 3DTV for consumers and higher than HDTV resolutions are to be tested in 2012 London Olympics. Xilinx Making Immersive 3D and 4K2K Displays Possible with 7 Series FPGA System Integration press release tells that Xilinx just introduced new 28nm Kintex™-7 Field Programmable Gate Array (FPGA)-based targeted reference designs and a new development baseboard for accelerating the development of next-generation, 3D and 4K2K display technologies at 2012 International CES. The network infrastructure will need an overhaul in 2012 due to the increasing amounts of high-definition video and other traffic.

ARM processor becomes more and more popular during year 2012. Power and Integration—ARM Making More Inroads into More Designs. It’s about power—low power; almost no power. A huge and burgeoning market is opening for devices that are handheld and mobile. The most obvious among these are smartphones and tablets, but there is also an increasing number of industrial and military devices that fall into this category. ARM’s East unimpressed with Medfield, design wins article tells that Warren East, CEO of processor technology licensor ARM Holdings plc (Cambridge, England), is unimpressed by the announcements made by chip giant Intel about the low-power Medfield system-chip and its design wins. Android will run better on our chips, says Intel. Look out what happens in this competition.

Bill McClean: Don’t broad-brush the semiconductor market article tells that year 2011 started off great, full of optimism and high growth expectations for the semiconductor industry. But that mellowed as the year progressed (total semiconductor market at 2% growth for this year, although smartphone increase very much). Going into 2012, there’s not a lot of optimism. Any thoughts on 2013? A: We’re thinking it’s going to be a little slower than 2012. So, we’re looking to a slower market—not a disaster.

Chip sales flat in 2011, will grow (a wee bit) in 2012 article tells that the prognosticators at Gartner have ranked the chip makers of the world by 2011 revenue and are calling the market for 2012, with a reasonably upbeat forecast for next year’s chip sales, but (paradoxically) a dreadful forecast for companies that make the gear to bake the chips. Disk shortages are expected to slow down PC sales for several quarters. Smartphones, tablets, and flash will represent more than three-quarters of the revenue growth between now and 2015.

There are also some more optimistic predictions for chip sales. Malcolm Penn, founder and chief analyst with semiconductor market analysis firm Future Horizons Ltd, is more bullish than most other market analysts. Bullish Penn sees chip market growth of 8% in 2012 article tells that Malcolm Penn has predicted that the global chip market will rise on an annual basis by 8% to $323.2 billion in 2012. Penn said that after a flat first quarter he expected the chip market to bounce back in the second half of the year. He considers that 8% growth is a “safe bet,” and indicated that annual growth “could easily be 20%.” For 2013 Future Horizons forecasts 20% annual growth.

EDN magazine writes in PC boards: Materials and processing are now a hot technology article that exotic substrates and fabrication methods are now commonplace. A dozen layers, thick copper, fine lines, and buried vias are just the processing side of the modern high-tech PCB. There are many processing options that have made PCBs truly a hot technology. Also the substrates themselves are now high tech. Traditional FR-2 (phenolic resin bonded paper) or FR-4 (glass-reinforced epoxy laminate) are not the only widely supported choices anymore. You could always specify Teflon or polyamide substrates for high-speed circuits. In addition to the old high tech like flex circuits, there are a host of improvements that make a whole new set of high-tech PCB designs that are truly a hot technology.

EDA industry predictions for 2012 mentions that 28-nm design starts will increase by 50% in 2012 and more people will be dabbling with 20 nm. The increased design sizes and complexity will create all kinds of pressure in the verification and test fields.

The rise in fake parts is also contributing to engineers’ fears that their products will be corrupted. Counterfeit electronic components were big issue in 2011, and the problem does not go away this year.

EDA industry predictions for 2012 mentions a trend, and one that has been going on for some time, is a continued migration of functionality from hardware to software. Dr Markus Willems of Synopsys attributed this to “the needs to support multiple standards simultaneously (wireless, multimedia), use the same hardware platform for product derivatives (automotive), quickly adjust to evolving standards (wireless), and react to changing market demands (all applications).” Increased rate of adoption of new technologies such as tablets, ultra-books, and their inherent demand for low-power solutions will help the EDA industry improve their importance. Electronic system-level design tools (ESL) continues to be an important thrust for the EDA industry. Increased adoption of the TLM 2.0 (Transaction-level modeling) standard is a popular theme. Several EDA companies have been busy writing books recently and self-publishing them.

Product Lifecycle Management (PLM) tools are taking product design to the next level (especially in automotive, aerospace, and defense). PLM was launched more than a decade ago with the lofty vision of creating an enterprise-wide, central repository for all product-related data, from the earliest customer requirements feedback through quality and failure data collected in the field by maintenance and support personnel. Product lifecycle management, sometimes “product life cycle management”, represents an all-encompassing vision for managing all data relating to the design, production, support and ultimate disposal of manufactured goods. What 2012 holds for Product Lifecycle Management? article tells about current PLM trends.

The prototype comes of age article tells that a radical change is about to happen in the typical development of an electronic system. The hardware-development flow will no longer be the center around which everything else revolves. The rising size and complexity of systems and the limitations of using a single-purpose model—the hardware-design model—have fueled the growth of new prototyping technologies. Among the changes now taking place in this area is the migration to higher levels of abstraction for hardware design. The ability to derive several implementations from a single high-level description is also desirable. Many hardware blocks now come with sophisticated software stacks, and they also must be integrated into the software flow.

‘KISS’ Among Engineers’ Top 2012 Concerns article tells that Rich Merritt agrees that we’ve forgotten the KISS principle especially in automation sector. “We’ve made everything so complicated, complex, and convoluted that we’ve entered the age of ‘transoptimal engineering,’ ” he says. “That is, things are so advanced and have so many features, they don’t work anymore.” Business development manager Herat Shah sees the pressures for complexity and price converging in an unhealthy manner. “The biggest issue for the automation and control supplier is to design and engineer something that’s the cheapest and the best,” he says. “Practically, this is not possible.” In addition to this there are security concerns: Stuxnet targeted controllers, and made engineers realize that factories aren’t immune to security threats.

How do you manage the Internet of you? article claims that electronics has gotten to the point (in the consumer space) where the only innovations are the mundane, the enhancements, the extensions. A computing device today (whether a tablet, a phone or a PC) can do what telephony, typewriters, pen and ink, film (motion and still), cameras, television, radio (basically all major mediums) did a generation ago. And yet… And yet we still innovate. We still build. We still buy. The devices in one sense feed the worst part of a personality: compulsiveness. They suppress pause and reflection. Think about it.

Car Electronics 2012

Wednesday, January 18th, 2012

The Year of The EV article tells that We can dub 2011 the year of the EV (electric vehicles) and gives a timeline what happened 2011. The end result is that today there are enough Volts on the road (along with competitors like Nissan’s Leaf, various hybrids, and an electric Ford Focus) that it might be safe to suggest that the electric car is here to stay.

There has been many different car charging connectors in use on electronic vehicles. Electric Car Charging Standards Split article tells that many car manufacturers have agreed on a single EV charging port connector standard that has been in development by the Society of Automotive Engineers (SAE) for several years. European car companies have been divided on standards for both AC and DC charging. The new single connector will support fast DC charging as well as be backward compatible with the J1772 AC charger that is standard on many plug-in electric vehicles today. I think that use of that standard will rise in 2012, and common charging standard will speed up the EV deployment.

Automotive electronics: What’s hot in 2012 article tells that in automotive electronics, 2012 looks to be a year of consolidation as technologies introduced previously become more widespread across model lines. In particular, voice recognition, with different features and interfaces, is seen as a way of distinguishing one brand from another, while electrified power trains in the form of hybrids and pure electric drives will be available in more models. In keep costs down driven auto industry the more mature the technology that goes into a car, the less risk of failure and costly warranty claims.

Cars and smartphones start to communicate using MirrorLink technology to allow new features. MirrorLink™ has been developed with the objective to provide a technology, offering seamless (extremely simple from the consumer perspective) connectivity between a smart phone and the in-vehicle infotainment system. It uses IP technologies in order to be independent of the physical transport mechanism and supports many car connectivity solutions (Bluetooth, WLAN, USB etc.). Whereas MirrorLink™ does allow any legacy application on the mobile device to show-up on the car display, it specifically enables easy development of mobile device based automotive applications.

Ethernet for Vehicles is gaining momentum in in the car. Ethernet for Vehicles Advances article tells that Ethernet technology in the car (a concept that was once unthinkable for the automotive industry) has been gaining momentum lately. Special interest group, known as the OPEN (One-Pair-Ether-Net) SIG, is aimed at driving broad-scale adoption of Ethernet in vehicles, largely to serve the expected boom of camera-based applications in cars. Many vehicles now have backup cameras, and many others are going to add cameras for such applications as lanekeeping, adaptive cruise control, and collision avoidance.

There is going to be an increasing number of Driver Information applications that involve displaying complex images and graphics. Xilinx Paves the Way for a New Generation of Automotive Driver Assistance and Infotainment Systems at CES 2012. World’s first Field Programmable Gate Array (FPGA) based Ethernet Audio/Video Bridging (EAVB) network implementation optimized for carrying high-speed data traffic within the automobile was shown at CES 2012. The IEEE 802.1 EAVB standard is already gaining the attention of a number of leading automotive manufacturers even though the specifications are still being finalized. OMG! Amazing home displays and automotive Ethernet AVB stuff from Xilinx article gives some more details what is expected in near future.

New electronics features are making challenges for developers. Automotive Electronics: Do We Really Need All This Stuff? article tells that everyone in the auto industry knows that the number of electronic control units (ECUs) in vehicles is nearing the point of unmanageability. Low-end vehicles now incorporate between 35 and 40 ECUs, while luxury cars may have 80 or more. “We’re right up against the limit right now. We need to find unique ways to integrate features and functions, and give our customers what they want without overloading our controllers.” The number of automotive features and functions keeps rising.

Would Cellphone Ban Secure Car Safety? article tells that the proliferation of in-car entertainment technologies (internet routers, smartphone links, MP3 connections, capacitive touch screens, etc.) are great for selling cars. Auto executives understand what consumers want: Many people don’t want a car with no extra features. Those new extra features have also sparked a serious debate about driver distraction dangers. “According to NHTSA [the National Highway Traffic Safety Administration], more than 3,000 people lost their lives last year in distraction-related accidents.” “You’re dealing with human nature here. People want what they want. And sometimes they want more than they should have.”

SparkFun: Why Open Source?

Telecom trends for 2012

Wednesday, January 4th, 2012

What can we expect for the fast-moving telecommunications market this year?

There are many predictions. I started looking for information from Twelve 2012 Predictions For The Telecom Industry and Top 12 Hot Design Technologies for 2012 articles. Then I did some more research on what is happening on the field and decided to make my own list of what is expected this year. You can go to the original information sources by clicking the links to see where all this information comes from.

The global telecommunications services market will grow at a 4% rate in 2012 (was 7% in 2011).

Mobile growth does not stop. The number of global mobile subscriptions will pass the 6 billion mark in February. India will pass China to become the world’s largest mobile market in terms of subscriptions.

The mobile handset market will surpass the $200 billion mark. Smartphones are most heavily used by people under 45, and that age group increasingly sees the smartphone or tablet as a portal to Facebook and Twitter, among other social networks. The demand for the chips that generate and process that data in smartphones is increasing (sales of smartphone applications processors surged to $2.2 billion in the third quarter of 2011). Six Companies Want Supremacy On The Smartphones Chip Market! Qualcomm Look Out!

There is lots of competition on mobile OS marker, but I expect that thing continue pretty much as 2011 ended: Android continues to boom, RIM and Microsoft decline. Symbian’s future is uncertain although Symbian started and finished 2011 as the undisputed king of mobile OSs (33.59%). Windows Phone will try to get to market and Leaked Windows Phone Roadmap gives us a peek into the future. Java Micro Edition making a comeback according to the NetApplications report because large number of low-cost feature phones. The real mobile application battle lines of 2012 will be drawn across the landscape of HTML5.Tizen open source project tries to push to mobile Linux market (first version Q1 2012) with ideas from Meego, LiMo and WebOS. Cars and smartphones start to communicate using MirrorLink technology to allow new features.

Mobile campaigns to be hot in 2012 presidential race article tells that though mobile advertising not seen much on the campaign trail, mobile strategy is expected to be important for attracting younger voters. Social networks played an important role in the last U.S. presidential election, but the explosive growth in smartphone usage and the introduction of tablets could make or break the candidates for president in 2012. Expect to see specialized apps to help campaign groupies follow the candidates.

Text messaging has been very profitable business for mobile phone operators and making them lots of money. Text Messaging Is in Decline in Some Countries tell that all signs point to text messaging’s continuing its decline. There has been already decline in Finland, Hong Kong and Australia. The number of text messages sent by cellphone customers in USA is still growing, but that growth is gradually slowing, “SMS erosion” is expected to hit AT&T and Verizon in this year or next years. The fading allure of text messaging is most likely tied to the rise of alternative services, which allow customers to send messages free using a cellphone’s Internet connection.

EU politicians want to ban roaming charges according to Computer Sweden magazine article. If the proposal becomes law in the EU, it takes away slippery roaming charges for mobile data (could happen earliest at summer 2012, but I expect that it will take much more time). Roaming robbery to end – 2015 article tells that the goal is that the mobile roaming fees should be completely abolished the 2015th.

Near Field Communication (NFC) is becoming available in many mobile phones and new flexibility via organic materials can help in implementing NFC. NFC-enabled SIM cards are expected to become a worldwide standard. Electronic wallet in smartphones probably takes a step forward with this. Google, opened the game with Google Wallet service. According to research firm ABI Research estimates that in 2012 NFC phones is growing 24 million to 80 million units. There is still years to wait until mass market on NFC wallets starts. ABI Research estimates that there is 552 million NFC enabled devices at year 2016.

The 4G technology WiMax will see the beginning of its end in Asia. Like operators in other regions, Asian operators will opt for the rival 4G technology LTE instead.

The number of active (installed) PCs worldwide will pass the 2 billion mark. Broadband penetration continues to increase. Broadband penetration of the world’s population will pass the 10% mark globally. IPTV (Internet Protocol TV) penetration of the world’s population will pass the 1% mark. Broadband technologies are fundamentally transforming the way we live. UN wants two-thirds of the world online by 2015.

Today’s Cable Guy, Upgraded and Better-Dressed article tells that the cable guy is becoming sleeker and more sophisticated, just like the televisions and computers he installs. The nearly saturated marketplace means growth for cable companies must come from all the extras like high-speed Internet service, home security, digital recording devices and other high-tech upgrades.

Ethernet displaces proprietary field buses. As Ethernet displaces proprietary field buses to facilitate the operation of the digital factory. Ethernet switches are the ubiquitous building block of any intelligent network. Ethernet has also become the de facto networking technology in industrial automation even in mission-critical local networks. Modern Ethernet switches have added significant new functionality to Ethernet while decreasing port prices. Ethernet for Vehicles also becomes reality largely to serve the expected boom of camera-based applications in cars.

Operators’ growth will increasingly depend on their having a cloud computing strategy, an approach for the high-growth IT service market and a clear value proposition for the enterprise market. Data center technologies will be hot topic. 10GBase-T Technology will become technically and economically feasible interface option on data center servers. 10GBase-T Technology allows you to use RJ45 connectors and unshielded twisted pair cabling to provide 10Mbps, 100Mbps, 1Gbps, and 10Gbps data transmission, while being backward-compatible with prior generations.

40/100 Gbit/s Ethernet will be a hot topic. Carriers and datacenters have been clamoring for the technology to expand their core backbone networks. 2012–A Return to Normalcy and Pragmatic, Power Conscious 100G article mentions that in 2010 and 2011, the industry saw the first real roll-outs of 100G transport solutions based on Coherent Detection and FPGA-based Framers. In 2012 we’ll start to see 100G taking a bigger place in the build out of new and existing networks around the world. The initial deployments of 100G are clearly too costly and too power hungry to be widely deployed as the primary transport technology, so optical transport marketplace will move to much lower power and lower cost Direct Detection optical transport solutions. The average WDM link for 10G is dissipating about 3.5W per optical module, the average WDM link per 100G is dissipating about about 100W.

5 Major Changes Facing the Internet in 2012 article tells that 2012 is poised to go down in Internet history as one of the most significant 12-month periods from both a technical and policy perspective since the late 1990s. This year the Internet will face or can face several milestones: root servers may have a new operator, new company could operate the .com registry, up to 1000 new top-level domains will start being introduced, additional 10,000 Web sites will support IPv6 and Europe will run out of IPv4 addresses.

No IPv6 Doomsday In 2012. Yes, IPv4 addresses are running out, but a Y2K-style disaster/frenzy won’t be coming in 2012. Of course there’s a chance that panic will ensue when Europe’s RIPE hands out its last IPv4 addresses this summer, but ‘most understand that they can live without having to make any major investments immediately. Despite running out of IPv4 addresses we will be able to continue to use IPv4 techniques (Asia depleted all of its IPv4 address space already April 2011). ISP’s and hosting companies will not run out of IPs. This only means that the price per IP will start to slowly grow. Forward thinking enterprises can spend the year preparing for the new IPv6 protocol (USA is expected run out of addresses next year). Comcast has said it will offer production-quality IPv6 services across its nationwide network in 2012.

Operators start to pay more attention to the business opportunity of “M2M” (machine-to-machine connections). Investment and innovation in M2M (think smart energy meters and fleet trackers for logistics) will follow.

Smart Grid technologies include smart power management and architecture system components are already hot. Smart meter deployment on the rise globally. The global power utilities are the next mega-market moving from analog, standalone systems to digital networked technology. The opportunities are huge in everything from wireless components in smart meters to giant power electronics. First cut of some very basic framework standards have been drafted and lots of works needs to be done (ensure safety!). Forward-looking utilities and such vendors have now put business units and plans in place. IPv6 is seen as a needed technology in implementing Smart Grid communications. IPV6 has become a buzz word for smart grid firms.

You Will See A Ton Of Hype Around “The Internet Of Things” article tells that “The Internet Of Things” is a catchy term revolving around the idea that most everyday objects around us will be equipped with internet-collected electronics, and this will open up new applications. You Will See A Ton Of Hype Around “The Internet Of Things”, and it is hard to say if The Internet Of Things will be a huge business or a passing fad. NXP Semiconductor’s vision of Internet of Things starts with lightbulbs. Wireless sensor networks will get attention. EE Times article Top ten Embedded Internet articles for 2011 gives you links to articles that help you to catch on those topics.

Security issues were talked about lot on 2011 and I expect the discussion will continue actively during year 2012. There are still many existing security issues to fix and new issues will come up all the time.

Self-healing electronics

Tuesday, January 3rd, 2012

One tiny fault inside battery or IC usually makes an entire electronics device is unusable. Scientists from University of Illinois have come up with an interesting solution to this. They have developed a technology to repair broken conductors instantly and automatically, without the people even notice the problem.

Self-healing electronics could work longer and reduce waste article tells that self-healing electronics uses microcapsules full of liquid metal sit atop a gold circuit. When the circuit is broken, the microcapsules rupture, filling in the crack and restoring the circuit.

This news was also mentioned by Tietoviikko and Prosessori.

Many great people died in 2011

Wednesday, December 28th, 2011

At year 2011 we saw the passing of many of the electronics and computer industry’s greatest engineers and inventors.

Jim Williams, who was considered one of the best analog circuit designers in the world, suffered a stroke and passed away on June 12, 2011. An Analog Life: Remembering Jim Williams article gives you information who he was. In Analog guru Jim Williams dies after stroke EDN’s Paul Rako and industry EEs reflect back on the life and work of Jim Williams, an engineer’s engineer and analog expert. Jim Williams, Circuits as art is a great article about Jim William’s artistry from the February 1987 edition of EDN. Cassidy: Jim Williams’ workbench captures his life and Silicon Valley article shows the Williams’ museum-worthy mess working table. His bench is now on exhibit at the Computer History Museum in Mountain View. Newnes has announced the publication of a 960-page book of Jim Williams’ application notes that span decades of Jim’s work.

Bob Pease was icon in the analog design world. Bob Pease was remembered for Pease Porridge and a whole lot more. Pease was the author of eight books, including Troubleshooting Analog Circuits, and held 21 patents. Analog engineering legend Bob Pease killed in car crash article tells that Bob Pease died in a car accident, which occurred as he was leaving a memorial service for his friend and fellow analog expert Jim Williams. Bob has a legacy as one of the greatest analog engineers in history due to his unique experiences.

Computer History Museum honors Jim Williams and Bob Pease.

C and Unix pioneer Dennis Ritchie reported dead on October.
