Compliant multilayered thermally-conductive interface assemblies and memory modules including the same

Abstract

A thermally-conductive interface assembly is suitable for dissipating heat from a memory module or other components. Thermal interface material is disposed on or along one side of a flexible thermally-conductive sheet. The thermally-conductive sheet can be bonded to, encapsulated within, or sandwiched between first and second layers of the thermal interface material. The thermally-conductive sheet may be a flexible perforated graphite sheet. The thermal interface material may be thermally-conductive polymer. The perforations in the graphite sheet may enable a polymer-to-polymer bond to form that may help mechanically bond the first and second layers to the graphite sheet and/or may help provide heat conduction between the first and second layers. The thermally-conductive interface assembly may include flexible thermal discharge material having a first side, a second side and perforations, and may be sandwiched between the first and second layers of the thermal interface material. Part of the thermal interface material may be disposed in the perforations. The thermally-conductive interface assembly may be positioned with respect to the components, so as to provide a thermally-conductive path from the components to the first layer of the thermal interface material.
