Abstract

A test handler is disclosed. A posture changing unit for changing a posture of a test tray on which semiconductor devices have been loaded changes the posture of the test tray in a soak chamber. While the posture of the test tray is changed, the devices can be pre-heated/pre-cooled, thereby reducing the soak chamber length and the pre-heating/pre-cooling time.
