Granted: 2021-10-21
Abstract: The present invention is related to a universal match plate for test handler and has a base, two guide plates, four guide blocks, four fasteners and two pushers. The base has a board and a fixed block. The guide plates are respectively disposed between the board and the fixed block. The fasteners respectively fix the corresponding guide blocks to the corresponding guide plates. The pushers are respectively mounted on the corresponding guide plates. Therefore, the user only changes the corresponding guide plates when the amount and positions of the pushers are required to be changed to match the amount and positions of a test socket of a different circuit board. Therefore, the user does not prepare different and complete match plate sets and does not remove and replace different match plate for different circuit boards. The test cost and the removing and replacing time are also decreased.
