Abstract
A system and method is disclosed that transfers carrier boards in a handler that supports the testing of electronic devices. A carrier board can be transferred from the transfer start position to one of the mid transfer positions and the transfer final position. Carrier boards, which are spaced apart from each other in a chamber, can be gathered adjacent to each other in the circulation direction of carrier board. The transfer speed and the total circulation speed of the carrier boards can be enhanced. The transfer speed of carrier board can be easily controlled according to the test conditions.
