Abstract:
1. An IC socket, comprising: a package guiding member provided with a package containing member for placing a semiconductor device at a predetermined location, said semiconductor device being provided on one face thereof with a plurality of external connection terminals; a plurality of contacting terminals arranged on a lower face of said package containing member so as to correspond to said plurality of external connection terminals of said semiconductor device placed in said package containing member with said face down; a pressurizing member comprising a weight and a shaft with a ball/rotating member for exerting pressurizing force downward onto said semiconductor device placed in said package containing member through a mass of said pressurizing member, said pressurizing member being movable with respect to said package guiding member such that said IC socket has an open position and a closed position; and a pressurizing member supporting system for holding said pressurizing member over, and not in contact with, said semiconductor device when said IC socket is in said closed position and subsequently gradually lowering said pressurizing member to bring said pressurizing member into contact with said semiconductor device.
