ABSTRACT:
An aligning apparatus for a semiconductor device test handler is provided which reduces semiconductor device loading and unloading time. An exchange unit of the handler includes a pair of aligners which operate independently to continuously transfer devices to a test site of the handler for test, and then away from the handler upon completion of the test. Both horizontal and vertical movement of each of the aligners facilitates the loading and unloading of semiconductor devices. This aligning apparatus provides for simplified design and operation of the aligners, and improves loading and unloading speed, thereby enhancing test efficiency.
