In addition, thermal greases do not require post-processing. However, some of the disadvantages associated with thermal greases are their tendency to "dry-out" and "pumpout" during prolonged periods of operation. Several factors affect the in-situ performance of thermal greases, one of them being the surfaces that interface with the grease (heat spreader/sink and silicon device or heat sink and heat spreader). In this paper, the effect of the surface characteristics of heat spreader/sink and silicon device on thermal and reliability performances is reported. The thermal and reliability tests designed for this study are also described.
Key words: Thermal grease, reliability, accelerated testing
