Abstract:
1. A side-docking type test handler comprising: a loading unit for loading untested semiconductor devices into a test tray which is at a loading position; a soak chamber for per-heating or pre-cooling the semiconductor devices loaded in the test tray transferred from the loading position in a horizontal state; a test chamber for allowing the untested semiconductor devices, which are loaded in the test tray transferred from the soak chamber, to be tested therein; a desoak chamber for recovering the temperature of the semiconductor devices loaded in the test tray transferred from the test chamber; an unloading unit for unloading the semiconductor devices, which are loaded in the test tray transferred from the desoak chamber to an unloading position, into customer trays while classifying the tested semiconductor devices into several classes depending on test results; a descending mechanism for lowering the horizontally postured test tray, which has been transferred into the soak chamber, down to a descent finish position; a vertical posture changing mechanism for changing the posture of the test tray, which has been lowered to the descent finish position, from the horizontal state to a vertical state, to transfer the test tray into the test chamber; and a horizontal posture changing mechanism for changing the posture of the test tray from the vertical state to the horizontal state before the test tray is transferred to the unloading position.
