Abstract:
A heat transfer apparatus for coupling to a pin grid array (PGA) device including an integrated circuit and mounted within a socket, wherein the socket is mounted upon a surface of a printed circuit board (PCB) and comprises two latching projections extending from opposite side surfaces, the heat transfer apparatus comprising:a thermally conductive heat sink, comprising: an opening in an underside surface for housing the PGA device and the socket; a lip surrounding the opening for thermally coupling to the PCB about the socket; a pair of holes extending through the heat sink from an upper surface of the heat sink into the opening; a spring clip for holding the heat sink in place relative to the PGA device, wherein the spring clip comprises two side members, and wherein each side member is adapted for attaching to a different one of the latching projections of the socket; and wherein each of the pair of holes in the heat sink is adapted to receive a different one of the side members of the spring clip.
