Patent ID: 7908747

Claim:
A method for assembling testing equipment for a semiconductor substrate comprising the steps of: overlaying a contact block on a dowel member and changing substrate, wherein said contact block is adjustable relative to said dowel member by the provision of a gap between the contact block and a screw that fixes the contact block and the dowel member and said contact block having a group of connection terminals to be electrically connected to circuit patterns in a semiconductor substrate and further having a mark detection hole having a predetermined positional relationship to said connection terminal group, said changing substrate having a group of electrodes to be electrically connected to said connection terminal group; making a positioning mark formed in said changing substrate to coincide with said mark detection hole by sighting through said mark detection hole and adjusting said contact block relative to said dowel member by the provision of the gap between the contact block and the screw, said positioning mark being formed in correspondence to said mark detection hole in said disposed contact block to have a predetermined positional relationship to the position of said electrode group; and coupling said contact block and said changing substrate so that said positioning mark and said mark detection hole coincide with each other and to a printed wiring board for supplying test signals to said electrode.
