Abstract
An automatic loading and unloading apparatus using servo motors allows simultaneous loading and unloading of two or more semiconductor device packages into and from test devices. The loading and unloading apparatus has a feeding mechanism which has a feed container carrying two semiconductor device packages which have not yet been tested; a loading tool for transferring those two semiconductor device packages from the feed container to a centering position; a DC test contact tool; an insertion tool; a removal tool; and a sorting station for sorting the semiconductor device packages depending on results of a burn-in test. The tools of the apparatus are driven by the action of servo motors, thereby allowing independent movements thereof in the vertical and horizontal directions.
