Chip Handler in Semiconductors are primarily used to for sorting, testing and transferring chips with the simple electrical interface diagram: ATE → ITA → DUT (package) ← Handler. And these machines are capable of processing thousands of chips in an hour. Normally, packaged parts use a handler to place the device on a customized interface board, then IC chip handler transfers finished chips to the inspection equipment for final visual and electrical performance test and then sort the chips into good, bad or other bins based on test results. Note: ATE: Automatic Test Equipment; ITA: Interface Test Adapter; DUT: Device Under Test.
