Abstract:
A test carrier for mounting thereon a semiconductor device having first terminals on a surface for the purpose of testing said semiconductor device, comprising:a carrier base; a contact sheet disposed on said carrier base, opposed to said semiconductor device, and having second terminals to be in contact with and connected to said first terminals of said semiconductor device and external electrodes for testing; a pressure applying member for applying predetermined contact pressure between said first terminals and said second terminals; a retaining member for detachably retaining said pressure applying member, said semiconductor device being enclosed with said retaining member and said pressure applying member; and a securing member for securing said contact sheet on said carrier base, wherein said retaining member is secured to said carrier base with said securing member and wherein the center of thermal expansion of said contact sheet secured by said securing member is offset from all said second terminals.
