“Authorities in the US have instructed Sony to conduct a recall of its Vaio laptops, after problems with overheating were reported.” started this article on the BBC’s web site. There is a saying, ” the news is never as good or as bad as it is first reported”. And so it is with this story. It’s not a product recall, as the story later goes on to explain, but what grabbed my attention was that the problem … 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

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

Just a quick post to let you know yours truly will be giving a presentation on: Thermal Design: A Key Part of the Electronics Design Flow At the UK Solutions Expo at the Heritage Motor Centre in Gaydon on 12th November. Miniaturization continues to increase power densities at all packaging levels, forcing design teams to identify new methods of cooling. The challenge remains consistent at all levels … Read More

It’s been a while since I posted on the BBQ. It’s not laziness per se, rather a combination of laziness and working on simulating the BBQ. This is just a quick post to point out a recent article in Electronic Design Magazine on the link between thermal management and product reliability which you can find here. Traditionally companies have sought to improve product reliability by reducing steady-state … Read More
