Description

Positioning apparatus for test tray of test handler

The present invention relates to a test handler.

The test handler is a device that supports semiconductor devices manufactured through a predetermined manufacturing process to be tested by a tester. The test handlers load semiconductor devices loaded in a customer tray into a test tray and transfer them to the test chamber, and the test chamber Complete semiconductor devices are unloaded from the test tray to the customer tray.

The test handler passes through the inner chamber before the test tray is transferred to the test chamber, and the test tray passing through the test chamber is transferred to the desequing chamber.

The inner chamber is for heating or cooling the semiconductor devices loaded on the test tray to a desired temperature, and the desock chamber is for reducing the heated or cooled device to a room temperature state.

The test tray heated or cooled to a predetermined test temperature condition in the inner chamber is transferred to the test chamber by a transfer means, and at the same time, the test tray of the test chamber is transferred to the desequence chamber. At this time, the decommissioning chamber is provided with a position setting device for completely introducing the test tray transferred from the test chamber to a desired position in the desuxing chamber.

If the test tray does not reach the correct position of the de-chamber chamber, further transfer of the test tray in the de-chamber may not be performed smoothly. Here, the additional transfer operation refers to lowering the test tray by a separate transfer device, or moving the test tray by one step in the de-chamber chamber to transfer the test tray to the unloading position.
