Claim Text:
1. A package for an integrated circuit chip module comprising: a generally planar substrate having first and second opposing surfaces; a plurality of integrated circuit chips mounted on said first surface of said substrate; a first heat sink provided with a plurality of pockets to accommodate and provide thermal communication with said plurality of integrated circuit chips, said first heat sink having sides forming a perimeter; a second heat sink located opposite said first heat sink with respect to said substrate, said second heat sink having sides forming a perimeter which is in continuous direct contact with the perimeter of said first heat sink such that said first and second heat sinks together substantially surrounding said integrated circuit chips on all sides; and thermal interface material disposed in a gap between said first heat sink and the at least one of said plurality of integrated circuit chips, wherein said gap has a dimension which is determined by at least one support rib of said first heat sink which forcibly abuts said substrate.
