ABSTRACT:
A pusher for a match plate of a test handler is disclosed which assists a tester to test the produced semiconductor devices. The pusher includes: a body part installed to an installation plate; and a pushing part that extends forward from a front side of the body part, for pushing a semiconductor device placed on an insert of a test tray. The pusher forms: an air through hole that extends through from a rear side of the body part to the front side of the pushing part, for guiding air of a certain temperature, supplied to the rear side of the body part from a duct, to be supplied to the semiconductor device; and at least one or more air outflow holes that extend through from at least one side of the pushing part and communicate with the air through hole, for allowing part of the air supplied from the duct through the air through hole to flow out to a test site. The pusher can reduce the temperature deviation of semiconductor devices at the test site.
