Abstract
A test handler decreases an index time in testing IC devices and improves a positioning accuracy for placing the IC devices on a test position of an IC tester. The test handler includes a turn table having a plurality of openings each of which is equally distanced from the other, and at least one of the openings is positioned right above a test socket provided on the IC tester, a plurality of carrier modules attached to the corresponding openings of the turn table where each of the carrier modules has a center opening to receive an IC device to be tested, and a press mechanism provided above the test socket of the IC tester to press the IC device in the carrier module downward so that pins of the IC device contact the test socket. The center opening of the carrier module has tapered walls at the periphery thereof where an upper portion of the center opening is wider than a lower portion of the center opening, and a plurality of guide slits are provided on the tapered walls of the center opening for guiding the pins of the IC device therethrough when the IC device is pressed by the press mechanism.
