Patent ID: 7119143

Claim:
A method for choosing the materials comprising a silicone thermal pad for use between a heat sink and an electronic component comprising the steps of: a. choosing a vinyl functional fluid product having R groups of H, OH or Me; b. choosing a hydrogen-capped polysiloxane product for addition to said vinyl functional fluid having R groups of H, Me or OH whereby to extend the chain of said vinyl functional fluid, said hydrogen-capped polysiloxane also partially cross linking said vinyl functional fluid; c. choosing a reactive silicone polymer cross linker containing the silicon-hydride groups whereby to enhance the cross linkage of said vinyl functional fluid; d. choosing an amount of powder in the form of thermally conductive particles to enhance heat conductivity; f. adding an inhibitor to control the reaction of said elements, if required; g. mixing said elements of said preceding steps to produce a thermal compound; h. de-airing said compound; i. adding a platinum catalyst, if required; j. mixing said compound in a manner to avoid air entrapment; k. heating said compound to accelerate curing, if required; l. fabricating said compound into a thermal pad; wherein said thermal pad is adapted for positioning between a relatively flat surface of a component and a relatively flat surface of a heat sinks wherein said vinyl functional fluid is approximately 25.7% by weight, said hydrogen-capped polysiloxane is approximately 1.5% by weight, said cross linker is approximately 0.7% by weight, and said aluminum oxide powder having particles of approximately 17.5 microns therein of approximately 70.6% by weight.
