Abstract
A test handler is provided, which comprises a test tray, at least one opening unit, and a position changing apparatus. The test tray aligns a plurality of inserts on its side. Each insert loads at least one semiconductor device thereon. The opening unit opens inserts at one part of the one side of the test tray. The position changing apparatus moves at least one opening unit in such a way that the at least one opening units can be located at another part of the one side of the test tray, such that the at least one opening units can open inserts at said another part of the one side of the test tray. The present invention can reduce the number of replaced parts according to change in the semiconductor device size, production cost, and part replacement time.
