Patent ID: 7518235

Claim:
An integrated circuit chip mounting structure comprising: a circuit board; a chip carrier electrically connected to said circuit board; an integrated circuit chip mounted on said chip carrier; a heat spreader having a bottom surface connected to a top surface of said integrated circuit chip, wherein said heat spreader has a top surface, opposite said bottom surface, that is larger in surface area than said top of said integrated circuit chip; a thermally conductive adhesive on said top surface of said heat spreader; a thermally conductive device thermally connected to said thermally conductive adhesive; a rigid frame positioned on said chip carrier, wherein said frame is adapted to impart, on said chip carrier, force transmitted from said thermally conductive device; spring-loaded alignment posts connected to said thermally conductive device, wherein said spring-loaded alignment posts extend through openings in said circuit board and openings in said frame, wherein said spring-loaded alignment posts comprise springs positioned between tops of said spring-loaded alignment posts and a bottom of said thermally conductive device, and wherein said alignment posts are positioned outside a periphery of said chip carrier; and compressible support members positioned between said bottom of said thermally conductive device and said frame, wherein said spring-loaded alignment posts pass through said circuit board, said frame, and said compressible support members, and wherein said frame contacts said chip carrier, said spring-loaded alignment posts, and said compressible support members.
