Abstract:
1. A method for mounting a heat sink to a heat source comprising the steps of: providing a heat source and a heat sink, said heat source having an area of heat concentration, determining an optimum size for a thermal interface material as a function of said area of heat concentration, placing said optimally sized thermal interface material between said heat source and said heat sink, and applying compression to said optimally sized thermal interface material between said heat source and said heat sink said step of determining further comprising the steps of establishing values that represent fixed characteristics for behavior of said thermal interface material in response to compression, establishing constraining equations for an initial size of said thermal interface material, a thickness of said thermal interface material as a function of said compression, and a thermal resistance of said thermal interface material, wherein said step of determining said optimum size for said thermal interface material comprises minimizing said thermal resistance of said thermal interface material.
