Abstract:
1. A memory module comprising: a printed circuit board substrate having first and second sides and one or more electronic components on at least one of the first and second sides; at least one thermally-conductive interface assembly comprising a flexible heat-spreading material between first and second layers of soft thermal interface material, which is conformable to a mating surface; and the at least one thermally-conductive interface assembly disposed relative to at least one of the first and second sides of the printed circuit board substrate such that the soft thermal interface material contacts and conforms to the mating surface of at least one of said one or more electronic components on the printed circuit board and such that there is a thermally-conductive heat path from one or more electronic components on the at least one of the first and second sides to the first layer of soft thermal interface material; wherein the flexible heat-spreading material comprises a perforated graphite sheet; and wherein the soft thermal interface material comprises thermally-conductive polymer gap filler that encapsulates the perforated graphite sheet and forms a polymer-to-polymer bond through one or more perforations in the perforated graphite sheet, and that is configured with sufficient conformability to closely conform to a mating surface when placed in contact with the mating surface, including a non-flat, curved, or uneven mating surface.
