A device test handler and a method for operating the same provide a significant reduction of the picking up and placing time periods, and reduce possible damage to the devices being tested. Devices and methods embodying the invention facilitate room temperature and high temperature testing within one device test handler to maximize testing efficiency. A test handler embodying the invention may include a pre-heater for pre-heating the devices on a loading shuttle as the loading shuttle passes to a test chamber. An indexing device in a test chamber of the device is used for successively transferring the devices from a loading shuttle to the test socket, and tested devices from the test socket to an unloading shuttle. Heat supply means may be provided for supplying a high temperature heat to the test chamber when the devices are required to be tested in a hot state. An unloading part having a plurality of trays movably fitted on the base is used to transfer devices from an unloading shuttle to output trays based on the testing results. |
