Patent ID: 7335030

Claim:
A semiconductor device socket comprising: a semiconductor mounting portion: a casing configured to hold the semiconductor device mounting portion and further configured to detachably hold on the top thereof either one of first and second pressing mechanisms of different types for pressing a semiconductor device onto the top of the semiconductor device mounting portion; a contact terminal probe pin cartridge selectively and detachably coupled to the lower end of each of said plurality of kinds of pressing mechanisms, said cartridge having at least first and second substrates for holding a plurality of probe pins to be electrically connected to terminals of the semiconductor device mounted to the semiconductor device mounting portion; a first set of fasteners for holding said first and second substrates together and to said casing; and a second set of fasteners for holding said first substrate to said casing and mounting portion without also holding said second substrate to said first substrate to thereby permit selective detachment of said second substrate to permit selective replacement of said pins.
