Patent ID: 7365985

Claim:
A memory module assembly comprising: a memory module printed circuit board assembly (PCBA) including: a substrate having opposing first and second surfaces, a plurality of first wiring traces formed on at least one of the first and second surfaces, each of the first wiring traces being connected to an associated metal contact pad formed along a connector edge of the substrate; and a first plurality of first integrated circuit (IC) devices and a second plurality of said first IC devices disposed on the first surface of the substrate such that upper surfaces of the first and second pluralities of first IC devices define a first plane that is parallel to the first surface of the substrate, and a second IC device disposed on the first surface between the first and second pluralities of first IC devices, the second IC device having an upper surface defining a second plane that is parallel to the first surface of the substrate, wherein the first plane is located between the second plane and the first surface of the substrate; a first heat-sink plate including first and second recessed regions respectively defining first and second planar underside surfaces, and a raised pocket region defining a third planar underside surface, the pocket region being disposed between the first and second recessed regions and first and second adhesive portions, the first adhesive portion being sandwiched between the first planar underside surface and the upper surface of at least one of said first plurality of said first IC devices, and the second adhesive portion being sandwiched between the second planar underside surface and the upper surface of at least one of said second plurality of said first IC devices, whereby the first heat-sink plate is rigidly secured to the memory module by the first and second adhesive portions.
