Abstract:
1. A test contactor for testing a semiconductor device comprising: a cylinder; a piston which is configured to reciprocate between a first position and a second position according to a change in pressure in the cylinder; a pressing part which is configured to change its location according to the reciprocating motion of the piston, wherein the pressing part is configured to be in contact with the semiconductor device when the piston is located at the first position, and wherein the pressing part is configured not to be in contact with the semiconductor device when the piston is located at the second position; and a guide block, wherein the guide block comprises a V-shaped guide groove configured to guide a path of the pressing part, wherein the V-shaped guide groove forms an obtuse angle, wherein the pressing part included at least one protrusion formed thereon which is insertable into the V-shaped guide groove, and wherein the at least one protrusion is configured to move along the V-shaped guide groove.
