Abstract
When a test handler loads semiconductor devices of user trays onto a test tray, the test handler adjusts a front/rear pitch or a right/left pitch between the semiconductor devices, adjusts the right/left pitch or the front/rear pitch, and loads the semiconductor devices. The test handler can sequentially adjust individually the front/rear pitch and the right/left pitch between the semiconductor devices, thereby reducing the apparatus weight and the loading time.
