APPARATUS FOR CONTACTING DEVICES TO TEST SOCKETS IN SEMICONDUCTOR TEST HANDLER

摘要

A device connecting apparatus of a semiconductor device test handler is provided to connect a semiconductor device to a test socket of a test head with the exact power, by detecting that the test head is combined to a test site and exactly setting the moving distance of a contact push unit according to the combined state of the test head. A device connecting apparatus of a semiconductor device test handler is composed of a test head(100) provided with a test socket(110) connected with a semiconductor device and detachably combined to one surface of a test site; a contact push unit(200) installed at the test site with facing the test head, to contact the semiconductor device to the test socket of the test head by pushing; a push unit driving part moving the contact push unit in the desirable distance; a control unit controlling the operation of the push unit driving part; and a distance measuring unit measuring the relative distance between at least one spot of the contact push unit and the test head.
