Test tray transferring apparatus for a test handler, test handler, and method of transferring test trays for a test handler

摘要

A test handler is disclosed. First and second gripping blocks for respective front and rear test trays to be transferred along a circulation path move together in a circulation direction, but move independently in a direction perpendicular to the circulation path and grip and release independently. The test trays can be transferred by a single power source and interference between an assisting a test and a transferring can be minimized.
