Nowadays the demand for thermal standards for power LEDs is increasing. On the one hand metrics for fair comparison of competing products are needed, on the other hand, designers of power LED based applications demand reliable and meaningful data for their daily work. Todaypsilas data sheet information does hardly meet any of these requirements. Part I compares the current situation in the LED world...
The increasing need for standardisation of thermal characterisation of LEDS and LED-based products. Manufacturers and end-users alike are crying for fair and useful thermal data, but for different reasons. It goes without saying that the LED-business is growing exponentially, in fact, much faster than analysts predicted five years ago. Unfortunately, the progress in thermal characterisation has not...
The present work aims at studying the cooling performance of a thermoelectric device that integrated with integrated heat spreader (IHS) on a flip-chip plastic ball grid array (FC-PBGA) package. The new thermoelectric device herein is fabricated on the metal substrates by flip-chip assembly process. Thermal performance of the new package was comprehensive studied. The thermal resistances of IHS with/without...
