Abstract

Abstract A chip carrier socket comprises a frame which defines and surrounds a space for receiving a chip carrier. A plurality of elongated contacts are carried by the frame, the contacts each defining a first section which resides within the inner surface of the frame, and are positioned to conductivity engage peripheral contacts of a chip carrier carried in the space. The contacts also each define a second section positioned on one side of the chip carrier socket to engage conductive members of a circuit board when the socket is carried thereon. The second sections each define a contact end which projects inwardly. The chip carrier socket defines an open aperture within and through the frame adjacent the inner surface so that the inwardly projecting contact ends are visible while the socket is carried on a circuit board.
