Abstract:
A thermal interface positionable at a juncture between an electronic component and a heat sink for facilitating heat transfer from said electronic component to said heat sink comprising:a) a generally planar substrate consisting essentially of a single layer having first and second surfaces and defining a first continuous peripheral edge, said peripheral edge having a portion thereof extending beyond the juncture between said electronic component and said heat sink; b) a first layer of a beat conductive composition formed substantially about said first surface of said substrate, and a second layer of a heat conductive composition formed substantially about said second surface of said substrate, said first and second layers further being formed upon said portion of said substrate extending beyond said juncture between said electronic component and said beat sink, said heat conductive composition comprising: i) 60% to 90% by weight of paraffin; and ii) 10% to 40% by weight of graphite; wherein said heat conductive composition has a melting point of approximately 51Â° C.; and c) a layer of adhesive formed upon a portion of a respective one of said layers of heat conductive material, said adhesive layer being localized upon said portion of said peripheral edge defined by said generally planar substrate extending beyond said juncture between said electronic component and said heat sink.
