Abstract:
A heat transfer assembly consisting essentially of:a substrate having an upper surface; a heat-generating source mounted on the upper surface of said substrate, said source having a first heat transfer surface disposed in confrontation with the upper surface of said substrate and an opposing second heat transfer surface of predefined margins; and a thermal dissipator mounted in heat transfer contact with the second heat transfer surface of said source, said dissipator comprising: a generally planar thermal dissipation member formed of a thermally-conductive, electrically-nonconductive ceramic material, said thermal dissipation member having an outer periphery, and including a top surface and a bottom surface defining a thickness dimension therebetween of less than about 100 mils (2.5 mm), said bottom surface having a central portion; and a pressure-sensitive adhesive layer interposed between said thermal dissipation member and said source to bond at least the central portion of the bottom surface of said thermal dissipation member to the second heat transfer surface of said source, wherein said thermal dissipation member is in heat transfer contact only with said source, wherein said ceramic material is aluminum oxide and wherein the outer periphery of said thermal dissipation member extends generally coterminously with or within the margins of the second heat transfer surface of said source.
