Abstract
A device and a method for testing a switch matrix used in semiconductor equipment and its ring connector are provided by the present invention. The switch matrix contains a test fixture adapter and the ring connector, and the ring connector comprises a plurality of first connecting pins on one end of the ring connector. The method is to first place a probe board on the test fixture adapter, and a plurality of testing pins are positioned on the probe board, each of the testing pins having one corresponding first connecting pin. Then, a resistor is electrically connecting between each of two adjacent testing pins, and electrically connecting the first connecting pins with the corresponding testing pins. Finally, a testing circuit is used to test each of the resistors so as to judge the operations of the switch matrix.
