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

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

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

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

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
