Patent ID: 7484285

Claim:
A system for mating and demating a plurality of socket board connectors mounted on a common surface of a socket board with respect to a plurality of corresponding motherboard connectors mounted on a motherboard where the socket board and the motherboard are provided in a semiconductor testing apparatus, the mating and demating system comprising: an adapter that is arranged opposite to a reverse side of the surface of the socket board on which the socket board connectors are mounted and is moved forward and backward in a direction to mate and demate the socket board connectors; and pulling means that is mounted in a protruding manner on the adapter or the socket board and engages with an engaging hole formed on the socket board or the adapter; wherein by moving the adapter backward, the pulling means pulls the socket board in a direction in which the socket board is separated from the motherboard, wherein a semiconductor component to be tested is placed on the socket board so that test signals are supplied to the semiconductor component through the socket board and the motherboard when they are connected with each other, wherein the pulling means has a shaft portion mounted in a protruding manner slidably with respect to the adapter and an bulging portion formed on a tip of the shaft portion and having a diameter larger than that of the shaft portion, wherein the engaging hole of the socket board has a passing hole through which the bulging portion of the pulling means can pass and a sliding hole which is continuous with the passing hole, allows the shaft portion of the pulling means to pass through, and disallows the bulging portion to pass through, and wherein the bulging portion passing through the passing hole of the engaging hole is moved to the sliding hole by sliding the shaft portion thereby to engage with the sliding hole such that the bulging portion can not drop.
