A heat sink/electronic component system using a phase change interstitial material (thermal interface material) can be optimized by using an adaptive clamping system that adjusts to the flow of the phase change material as it sets with a rise in temperature. The particular thermal clamping system being evaluated in this white paper is that of a servo motor inverter. This thermal system consists of a standard heat sink-fan forced air cooling system. This concept could be applied to any system requiring a phase change thermal interface material.
