A thermoelectric cooler integrated with IHS on a FC-PBGA package
2007
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 TEC were also compared. Moreover, a series of experiments have been carried out to investigate the effects of air velocity and the input current of thermoelectric device. The results showed that the integrated thermoelectric device can reduce the thermal resistance of FC-PBGA package significantly.
