			<content:encoded><![CDATA[<p>“<a href="http://nepp.nasa.gov/whisker/background/">Tin whiskers</a>” is not an imaginative, fanciful term for some aspect of electronics manufacturing.Tin <a href="http://en.wikipedia.org/wiki/Whisker_%28metallurgy%29">whiskers</a> 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.</p>
<p><a href="http://www.eetimes.com/design/military-aerospace-design/4230652/Understanding-and-mitigating-tin-whiskers">Understanding and mitigating tin whiskers</a> 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.</p>
<p><a href="http://nepp.nasa.gov/whisker/photos/pom/2004april.htm"><img src="http://www.epanorama.net/blog/wp-content/uploads/2012/01/2004april-hot-dip-limits.jpg" alt="2004april-hot-dip-limits" title="2004april-hot-dip-limits" width="352" height="263" class="alignnone size-full wp-image-8452" /></a></p>
<p><a href="http://www.nytimes.com/2011/02/09/opinion/09wed2.html?_r=1">Toyota has had problems with uncontrolled acceleration</a>. Earlier report have said that the <a href="http://www.nytimes.com/2011/02/09/opinion/09wed2.html?_r=1">acceleration problems that led to the recall of nearly eight million Toyota cars and trucks in 2009 and 2010 were mechanical</a>. <a href="http://www.leftlanenews.com/a-closer-look-at-toyotas-sudden-acceleration-problem.html">Yet some believe that the issue goes beyond the floor mats</a> and some new material on that has just surfaced. <a href="http://www.edn.com/article/520531-Toyota_accelerations_revisited_hanging_by_a_tin_whisker.php?cid=NL_EE+Times">Toyota accelerations revisited—hanging by a (tin) whisker</a> article tells that a <a href="http://nepp.nasa.gov/whisker/reference/tech_papers/2011-NASA-GSFC-whisker-failure-app-sensor.pdf">NASA paper</a> 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 &#8220;failed&#8221; sensor from a 2003 Camry and at least two other similar units that did not malfunction. The <a href="http://nepp.nasa.gov/whisker/reference/tech_papers/2011-NASA-GSFC-whisker-failure-app-sensor.pdf">NASA paper</a> gives further insight by detailing tin whisker physical behavior as well as outlining guidelines and methods of detecting whiskers. </p>
<p><a href="http://nepp.nasa.gov/whisker/reference/tech_papers/2011-NASA-GSFC-whisker-failure-app-sensor.pdf"><img src="http://www.epanorama.net/blog/wp-content/uploads/2012/01/toyotawhisker.jpg" alt="toyotawhisker" title="toyotawhisker" width="450" height="331" class="alignnone size-full wp-image-8454" /></a></p>
<p><a href="http://www.eetimes.com/design/military-aerospace-design/4230652/Understanding-and-mitigating-tin-whiskers?Ecosystem=communications-design">Understanding and mitigating tin whiskers</a> 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.</p>
<p>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. </p>
<p>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. </p>
<p>Here are some <a href="http://nepp.nasa.gov/npsl/Prohibited/na-044.pdf">suggestions for reducing the risk of tin whiskers</a>:<br />
1. Do not use pure tin. <a href="http://nepp.nasa.gov/npsl/Prohibited/na-044.pdf">Studies have shown that alloying tin with a second metal reduces the propensity for whisker growth</a>. (minimum of 3% lead by weight is acceptable)<br />
2. Do not rely on the order paperwork. Use <a href="http://en.wikipedia.org/wiki/X-ray_fluorescence">x-ray fluorescence</a> (XRF) to verify finish on all critical parts.<br />
3. Refinish a pure tin-finished part with a hot-solder dip. <a href="http://nepp.nasa.gov/npsl/Prohibited/na-044.pdf">Stripping and replating is a recommended approach and is a service offered by some of the original part manufacturers</a>.<br />
4. Use some type of encapsulation or conformal coating. <a href="http://www.xmultiple.com/Application%20Notes/Application%20Note-724%20Tin%20Whiskers.pdf">Uralane 5750 conformal can provide some benefit by reducing the growth rate, but tin whiskers can grow through conformal coating</a>.</p>
<p>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. <a href="http://www.eetimes.com/design/military-aerospace-design/4230652/Understanding-and-mitigating-tin-whiskers">Because of the potentially dangerous and unpredictable risks of pure tin, it is not presently used in medical devices</a>.</p>
<p>NASA has lost satellites due tin whisker. <a href="http://nepp.nasa.gov/whisker/">NASA Tin Whisker (and Other Metal Whisker) Homepage</a> has more details on that. <a href="http://www.te.com/customersupport/productcompliance/pdf/tyco_lf_customer_packet_whiskers.pdf">Tin Whiskers in Electronics Components</a> white paper from <a href="http://www.te.com/">Tyco Electronics</a> is also good reading with lots of pictures.</p>

			<content:encoded><![CDATA[<p>Our society relies increasingly on information technology (IT). In such a society, it is important that we, as citizens, trust and are satisfied with services utilizing IT. Unfortunately, IT problems in the use of services are part of our daily lives and. And they are frequently reported by the mass media. </p>
<p>Usually most of the IT problems visible to society are the same ones that system and service providers perceive to be the most problematic. Compensation alone will not satisfy users when the incident creates unpredictability and uncertainty for them. After service degradation, users are eager to use the service again if they receive relevant information. Information and knowledge thus play a significant role in incidents. Users will continue to IT after the failure, using a service, most likely, when they get the problem situation in a sufficient factual information.  </p>
<p>This is stated in a recent Finnish study, <a href="http://herkules.oulu.fi/isbn9789514296994/isbn9789514296994.pdf">doctoral thesis</a> <a href="http://urn.fi/urn:isbn:9789514296994">Information technology incidents in the present information society : Viewpoints of service providers, users, and the mass media</a>, which examined the users&#8217; thinking and intentions of the services provided at the time of their IT-related problems after the failures.</p>
<p><a href="http://herkules.oulu.fi/isbn9789514296994/isbn9789514296994.pdf"><img src="http://www.epanorama.net/blog/wp-content/uploads/2011/12/itservice.jpg" alt="itservice" title="itservice" width="450" height="110" class="alignnone size-full wp-image-6976" /></a></p>
<p>Clear information can bring significant competitive advantages over other service providers.</p>

			<content:encoded><![CDATA[<p>You can see quite often in big events that PA speakers are hidden behind large banners. Often times the event organizers want the speaker stacks covered with some client-related graphics. The question which comes to mind is how much does this kind of covering hurt the sound quality? What is the reality? <a href="http://www.controlgeek.net/blog/2012/1/27/do-graphic-vinyl-banners-affect-sound-transmission.html">Do Graphic Vinyl Banners Affect Sound Transmission?</a> article at <a href="http://www.controlgeek.net/">John Huntington&#8217;s Blog</a> takes a practical approach to test what is the effect. The end result was that it never seemed that this vinyl affected the sound all that much. Normally the wind, humidity, and other factors outdoors have a far greater impact on the quality of the sound than these banners. The <a href="http://www.controlgeek.net/blog/2012/1/27/do-graphic-vinyl-banners-affect-sound-transmission.html">article has some measurement results</a> (using SMAART) for those interested in them.</p>

			<content:encoded><![CDATA[<p>ARM processor becomes more and more popular during year 2012. <a href="http://www.rtcmagazine.com/articles/view/102403?utm_source=ePubXpress&#038;utm_medium=email&#038;utm_term=Power+and+Integration%E2%80%94ARM+Making+More+Inroads+into+More+Designs&#038;utm_content=RTC+Magazine+Digital+E-Newsletter&#038;utm_campaign=120103_rtcenewsletter_jms">Power and Integration—ARM Making More Inroads into More Designs</a>. It’s about power—low power; almost no power. A huge and burgeoning market is opening for devices that are handheld and mobile, have rich graphics, deliver 32-bit multicore compute power, include Wi-Fi, web and often 4G connectivity, and that can last up to ten hours on a battery charge.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. </p>
<p>The rivalry between ARM and Intel in this arena is predictably intense because try as it will, Intel has not been able to bring the power consumption of its Atom CPUs down to the level of ARM-based designs (Atom typically in 1-4 watt range and a single ARM Cortex-A9 core in the 250 mW range). <a href="http://www.edn.com/article/520584-ARM_s_East_unimpressed_with_Medfield_design_wins.php?cid=NL_Newsletter+-+EDN+Today">ARM&#8217;s East unimpressed with Medfield, design wins</a> 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 <a href="http://www.engadget.com/tag/medfield/">Medfield</a> system-chip and its design wins. On the other hand <a href="http://www.edn.com/article/520600-Android_will_run_better_on_our_chips_says_Intel.php?cid=EDNToday_20120118">Android will run better on our chips</a>, says Intel. Look out what happens in this competition.</p>
<p><a href="http://confidential.eetimes.com/news-updates/4234202/Windows-on-ARM-Spells-End-of-Wintel">Windows-on-ARM Spells End of Wintel</a> article tells that Brokerage house Nomura Equity Research forecasts that the emerging partnership between Microsoft and ARM will likely end the Windows-Intel duopoly. The long-term consequences for the world&#8217;s largest chip maker will likely be an exit from the tablet market as ARM makes inroads in notebook computers. <a href="http://www.osnews.com/story/22704/Intel_Atom_vs_ARM_Cortex-A9">As ARM is surely going to keep pointing out to everyone, they don&#8217;t have to beat Intel&#8217;s raw performance to make a big splash in this market, because for these kinds of devices, speed isn&#8217;t everything, and their promised power consumption advantage will surely be a major selling point.</a></p>

The University of Washington and Microsoft Research published a <a href="http://www.cs.washington.edu/homes/dhalperi/pubs/halperin_flyways_sigcomm11.pdf">paper at the Association of Computing Machinery&#8217;s SIGCOMM 2011 conference</a> late last year about their tests of 60GHz wireless links in the data center.

			<content:encoded><![CDATA[<p>Packet capture is one of the most fundamental and powerful ways to do network analysis.</p>
<p>If you think that <a href="http://www.tcpdump.org/">tcpdump</a> has been made obsolete by GUI tools like <a href="http://www.wireshark.org/">Wireshark</a>, think again. <a href="http://www.wireshark.org/">Wireshark</a> is a great application; it&#8217;s just not the right tool for the job in every situation.</p>
<p><a href="http://www.tcpdump.org/">tcpdump</a> uses a &#8220;one-off-command&#8221; approach that lends itself to quick, on-the-spot answers. You can run it through an SSH session, doesn&#8217;t need X and is more likely to be there when you need it.  And, because <a href="http://www.tcpdump.org/">tcpdump</a> uses standard command-line conventions (such as writing to STDOUT, which can be redirected), <a href="http://www.tcpdump.org/">tcpdump</a> can be used in all sorts of creative, interesting and extremely useful ways. </p>
<p><a href="http://www.tcpdump.org/"><img class="alignnone size-full wp-image-8284" title="logo" src="http://www.epanorama.net/blog/wp-content/uploads/2012/01/logo.png" alt="logo" width="956" height="103" /></a></p>
<p>You can even use <a href="http://www.tcpdump.org/">tcpdump</a> and <a href="http://www.wireshark.org/">Wireshark</a> together by <a href="http://www.wireshark.org/docs/wsug_html/#AppToolstcpdump">capturing the network data with tcpdump for viewing with Wireshark</a>. To ensure that you capture complete packets, use the following command:</p>
<pre>
tcpdump -i &lt;interface&gt; -s 65535 -w &lt;some-file&gt;
</pre>
<p><a href="http://www.linuxjournal.com/content/tcpdump-fu">tcpdump fu</a> article introduces some of the basics of packet capture and provide a breakdown of tcpdump syntax and usage. <a href="http://www.tcpdump.org/tcpdump_man.html">Manual page of tcpdump</a> lists you all the command line options you can use.</p>
<p>If you are embedded Linux system developer, remember that you can easily fit the <a href="http://www.tcpdump.org/">tcpdump</a> program inside a small embedded Linux system without too much problem (which is not the case with <a href="http://www.wireshark.org/">Wireshark</a>, because it is a huge program that needs GUI and has many dependencies).</p>

<p>ARM processor becomes more and more popular during year 2012. <a href="http://www.rtcmagazine.com/articles/view/102403?utm_source=ePubXpress&#038;utm_medium=email&#038;utm_term=Power+and+Integration%E2%80%94ARM+Making+More+Inroads+into+More+Designs&#038;utm_content=RTC+Magazine+Digital+E-Newsletter&#038;utm_campaign=120103_rtcenewsletter_jms">Power and Integration—ARM Making More Inroads into More Designs</a>. 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. <a href="http://www.edn.com/article/520584-ARM_s_East_unimpressed_with_Medfield_design_wins.php?cid=NL_Newsletter+-+EDN+Today">ARM&#8217;s East unimpressed with Medfield, design wins</a> 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 <a href="http://www.engadget.com/tag/medfield/">Medfield</a> system-chip and its design wins. <a href="http://www.edn.com/article/520600-Android_will_run_better_on_our_chips_says_Intel.php?cid=EDNToday_20120118">Android will run better on our chips, says Intel</a>. Look out what happens in this competition.</p>
<p><a href="http://www.edn.com/article/520266-Bill_McClean_Don_t_broad_brush_the_semiconductor_market.php?cid=NL_Newsletter+-+Electronic+News+Today">Bill McClean: Don&#8217;t broad-brush the semiconductor market</a> 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. </p>
<p><a href="http://www.theregister.co.uk/2011/12/20/gartner_2011_semiconductor_forecast/">Chip sales flat in 2011, will grow (a wee bit) in 2012</a> 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&#8217;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. </p>
<p>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. <a href="Bhttp://www.edn.com/article/520658-Bullish_Penn_sees_chip_market_growth_of_8_in_2012.php?cid=EDNToday_20120123">Bullish Penn sees chip market growth of 8% in 2012</a> 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 &#8220;safe bet,&#8221; and indicated that annual growth &#8220;could easily be 20%.&#8221; For 2013 Future Horizons forecasts 20% annual growth. </p>

<p>EDN magazine writes in <a href="http://www.edn.com/article/520298-PC_boards_Materials_and_processing_are_now_a_hot_technology.php">PC boards: Materials and processing are now a hot technology</a> 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 <a href="http://en.wikipedia.org/wiki/FR-2">FR-2</a> (phenolic resin bonded paper) or <a href="http://en.wikipedia.org/wiki/FR-4">FR-4</a> (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.</p>

The increased design sizes and complexity will create all kinds of pressure in the verification and test fields. </p>
<p>The <a href="http://www.epanorama.net/blog/2011/10/19/counterfeit-parts/">rise in fake parts</a> is also contributing to engineers&#8217; fears that their products will be corrupted. <a href="http://www.epanorama.net/blog/2011/10/19/counterfeit-parts/">Counterfeit electronic components were big issue in 2011</a>, and the problem does not go away this year. </p>

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. <a href="http://www.design-reuse.com/news/8653/esl-tools-eda-giants-game.html">Electronic system-level design tools</a> <a href="http://www.edn.com/blog/Practical_Chip_Design/41559-EDA_industry_predictions_for_2012.php?cid=NL_Newsletter+-+EDN+Today">(ESL) continues to be an important thrust for the EDA industry</a>. <a href="http://www.edn.com/blog/Practical_Chip_Design/41559-EDA_industry_predictions_for_2012.php?cid=NL_Newsletter+-+EDN+Today">Increased adoption of the TLM 2.0</a> (<a href="http://en.wikipedia.org/wiki/Transaction-level_modeling">Transaction-level modeling</a>) standard is a popular theme. <a href="http://www.edn.com/blog/Practical_Chip_Design/41573-An_interesting_trend_with_EDA_books.php?cid=EDNToday_20120123">Several EDA companies have been busy writing books recently and self-publishing them</a>.</p>

<p><a href="http://www.edn.com/article/520449-The_prototype_comes_of_age.php?cid=NL_Newsletter+-+EDN+Today">The prototype comes of age</a> 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. </p>
