  • Patent number: 7419378
    Abstract: Example embodiments of the present invention include a socket for testing a semiconductor package. The socket comprises a body having a through hole. A lower magnet is disposed in a lower region of the through hole, and a first type magnetic pole of the lower magnet is directed upward. An upper magnet is disposed in an upper region of the through hole, wherein the first type magnetic pole of the upper magnet is directed toward the lower magnet. The upper and lower magnets are structured to absorb a shock wave which is generated when the semiconductor package is arranged for testing. A conductive medium is disposed between the lower magnet and the upper magnet to electrically couple contactors of the semiconductor package to a base substrate of the socket.
