Patent ID: 7579826

Claim:
A test socket for a semiconductor device ( 10 ) comprising: conductive substrates ( 40 ) electrically connected to terminals ( 11 ) of the semiconductor device ( 10 ) and lead terminals ( 21 ) of a test board ( 20 ); an insulating elastic element ( 50 ) to fix the conductive substrates ( 40 ); and wherein the conductive substrates ( 40 ) have contact point parts ( 41 ) exposed to the outside of the test socket on upper and lower surfaces of the insulating elastic element ( 50 ) to be in contact with the terminals ( 11 ) of the semiconductor device ( 10 ) and the lead terminals ( 21 ) of the test board, the conductive substrates have slant parts ( 44 ) provided to connect the contact point parts ( 41 ) on upper and lower surfaces of the insulating elastic element ( 50 ) so that the conductive substrates ( 40 ) are each in the shape of Z, and the conductive substrates alternately face in opposite directions so that adjacent pairs of the conductive substrates are symmetrically and repetitively positioned to face each other.
