Estimating the term…
An article of manufacture comprises a composite, layered, and compressible TIM differentially adhered to a heat-spreader surface and a heat-source surface, such as a circuit card, where at least one of the surfaces comprises an uneven surface, and the TIM is compressively bonded to the uneven surface. The adhesive strength of the TIM to the heat-spreader surface is unequal to the adhesive strength of the TIM to the heat-source surface, and is adjusted so that the heat-spreader surface and the heat-source surface can be separated without damaging the heat-source surface. A process comprises manufacturing the article of manufacture.
An article of manufacture comprising a thermally conductive composite material to conduct heat between a first surface and a second surface in which the adhesive strength between said composite and said first surface is not equal to the adhesive strength of said composite and said second surface.
An article of manufacture comprising a composite, layered, and compressible TIM differentially adhered to a heat-spreader surface and a heat-source surface, wherein the adhesive strength of said TIM to said heat-source surface is not equal to the adhesive strength of said TIM to said heat-spreader surface and said adhesive strength of said TIM to said heat-source surface and said adhesive strength of said TIM to said heat-spreader surface is adjusted so that said heat-spreader surface and said heat-source surface can be substantially separated without damaging said heat-source surface.
A process for manufacturing a device comprising forming a composite, layered, and compressible TIM having substantially opposed surfaces with different adhesivity, positioning one said surface of said TIM on a heat-spreader surface and the other said surface of said TIM on a plurality of heat-source surface, wherein at least one of said heat-source surfaces or one of said heat-spreader surfaces comprises an uneven surface, compressively bonding said TIM to said heat-spreader surface and said heat-source surface, the adhesive strength of said TIM to said heat-spreader surface and said heat-source surface being adjusted so that said heat-spreader surface and said heat-source surface can be substantially separated without damaging said heat-source surface.
