Abstract
A pusher provided in an autohandler presses a semiconductor device toward a socket to allow the electrodes thereof to contact the socket pins of the socket during testing the electric characteristics of the semiconductor device. The pusher includes a rigid pusher body and a balloon receiving therein fluid and provided on the front end of the pusher body. The pressure inside the balloon is controlled to allow the balloon to press the semiconductor device with a uniform pressure.
