Abstract:
Semiconductor mounting apparatus comprising:a printed circuit board having first and second opposing surfaces and having a plurality of conductive contacts arranged in a predetermined pattern on said first surface; a socket having a plurality of contacts arranged in said predetermined pattern, said socket being disposed on and aligned with said printed circuit board first surface such that said socket contacts are in conductive abutting relation with said printed circuit board contacts; an integrated circuit having a contact surface, a heat transfer surface and an upper surface, said integrated circuit having a plurality of contacts on said contact surface arranged in said predetermined pattern, said integrated circuit being disposed in said socket and positioned such that said integrated circuit contacts are in conductive abutting relation with said socket contacts; a pressure plate disposed in abutting relation with said integrated circuit upper surface, said pressure plate having an opening therethrough; a load cell including a first spring member, said load cell disposed adjacent said second surface of said printed circuit board; a linkage extending through at least one opening in said printed circuit board and coupling said load cell to said pressure plate, said load cell being operative to apply to said upper surface of said integrated circuit a first force through said linkage and said pressure plate; a heat sink having a bottom surface extending through said opening in said pressure plate and abutting said heat transfer surface of said integrated circuit when said heat sink is disposed in a mounting position with respect to said pressure plate; at least one second spring member coupled to said pressure plate, said second spring member abutting said heat sink and urging said heat sink bottom surface toward said heat transfer surface of said integrated circuit with a second force.
