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 … [Read more...]
Self-Healing Electronics Could Work Longer, Reduce Waste
A team of University of Illinois engineers has developed a self-healing system that restores electrical conductivity to a cracked circuit in less time than it takes to blink. Led by aerospace engineering professor Scott White and materials science and engineering professor Nancy Sottos, the researchers published their results in the journal Advanced Materials. As electronic … [Read more...]
IBM Retiree Wins Award from Engineers Society
Robert E. Simons was named the 2011 winner of the Allan D. Kraus Thermal Management Medal given recently by the committee that manages the annual award for the American Society of Mechanical Engineers. Simons is a retired IBM senior technical staff member who has had a 45-year career in the management of heat in electronics and holds more than 130 patents. He joined IBM in 1966 … [Read more...]
Editorial: Looking Back
In the editorial in the fall issue of ElectronicsCooling, my good friend and colleague Clemens Lasance wrote, “It is the privilege of an editor to discuss any subject that comes to mind, as long as it is (remotely) linked to the theme of the journal.” So, as the editor responsible for this issue of the magazine, I want to avail myself of this privilege. As I contemplate what I … [Read more...]
Thermal Facts and Fairy Tales: Heat Sinks, Heat Exchangers and History
As far as history goes, the field of electronics cooling does not have a very long past. A rather quick look through my personal reference material that is strictly geared towards cooling electronics had at the earliest some US Navy documents from the 1950s [1]. Comparing the solution techniques available today to those available then shows that we have both much better tools … [Read more...]
