Author Clemens J.M. Lasance, Guest Editor Fact: many papers discussing LED thermal management issues report values of about 100 W/cm2 and use the same arguments that are valid for ICs to demonstrate that some critical value has been reached. The question to be addressed: is this indeed a fact, or can it be shown to be a fairy tale, and hence do we need different … [Read more...]
Understanding the Thermoreflectance Coefficient for High Resolution Thermal Imaging of Microelectronic Devices
Authors Kazuaki Yazawa, Microsanj/Purdue University Dustin Kendig, Microsanj Peter E. Raad, TMX Scientific/SMU Pavel L. Komarov, SMU Ali Shakouri, Purdue University Introduction Thermoreflectance thermal imaging is an optical technique for measuring, with external illumination, the relative change in the surface reflectivity as a function of temperature for a … [Read more...]

Nanoscale Device Recycles Waste Heat into Power
Researchers from the University of Rochester in New York have proposed a “new type of nanoscale engine” that recycles heat emitted from a device and uses it to power the same device. According to Andrew Jordan, a theoretical physics professor at the University of Rochester, the new nanoscale engine would use quantum dots—manufactured systems that act as “artificial atoms” … [Read more...]
“Golf Ball Dimple” Cooling Fans Added to Distribution Portfolio
Luso Electronics, a distributor of thermal management products, has announced the addition of Zaward Corporation’s patented “Golf Fan” products for thermal management in computing and industrial applications. According to Luso Electronics, the design for the new fans is based on “the dimpled surface of a golf ball” and “shows improved airflow and low noise at the same rotating … [Read more...]
