Brave New World?

Posted by Nazita Saye

Nazita Saye I live and work in the burbs but I go into London every week. I usually hang out where my friends live. But from time to time work takes me to the square mile. The square mile is where most of the financial services industry is based in London. On days where I find myself in that neighborhood I feel like a country bumpkin. You see I tend to walk just a nudge slower than the masses – I’m used to … Read More

LEDs

3 Jan, 2012

Robin Bornoff LED based lighting is now a very hot topic (believe me, in electronic thermal management circles that used to be funny, the first few times). Control of packaged IC junction temperatures will always have a bearing on reliability but for LEDs thermal also effects functional performance in terms of brightness and colour. The hotter they get, the dimmer they appear. A particular contradiction in the context … Read More

John Wilson Just a quick note that I will be participating in an EDN Editorial Webcast on Friday, June 25, 2010.  There are four panelists that offer up some valuable insight into the challenges associated with the reliability of LEDS.  LEDS are a relatively new technology when compared to other semiconductor devices and standards for testing and reliability prediction are not yet universally accepted. You can … Read More

MCPCB, Reliability, LEDs, Thermal Testing

Nazita Saye Let’s see a show of hands. How many of you know what I’m talking about? Yes, this was the call to action for Speedy Gonzales, the fastest cartoon mouse (and before the lawyers get involved, Speedy Gonzales and Looney Tunes are trademarks and or trade names of Warner Brothers. All rights reserved). A direct translation of it means: Up! Up! Go on! Go on! And he’d usually yell it out before speeding off … Read More

CFD, Airflow, LEDs

24 Mar, 2010

John Parry Thermal management of LEDs (Light Emitting Diodes) is an important application for CFD software, which is helping designers use LEDs for high-power lighting applications. However, LEDs are changing our lives in so many more ways than simply providing more energy efficient or more aesthetic lighting solutions. Last year I posted about a light therapy device that desensitizes the nasal passages, inhibiting … Read More

John Parry It was very interesting to read this article about the work IBM are undertaking together with École Polytechnique Fédérale de Lausanne (EPFL) and the Swiss Federal Institute of Technology Zurich (ETH) on a 3D stacked architecture for multiple cores. The four year collaborative project, called CMOSAIC, promises to deliver an interconnection density from 100 to 10,000 connections per square millimetre … Read More
