Title:
TEST SYSTEM WITH TEST TRAYS AND AUTOMATED TEST TRAY HANDLING
Document Type and Number:
WIPO Patent Application WO/2013/119394
Kind Code:
A3
Abstract:
A test system may be provided in which devices under test (DUTs) are loaded into test trays. Test trays may be tested at test stations. Test trays may be moved between test stations using a conveyor belt system. Each test station may include test equipment for testing DUTs and automated loading equipment for latching incoming test trays moving along the conveyor belt. The automated loading equipment may include a first movable arm configured to pick up a test tray from the conveyor belt and a second movable arm. The first arm may hand off (transfer) the test tray to the second arm. The second arm may move the test tray towards associated test equipment for testing. Upon completion of testing, the second arm may drop off the test tray onto the conveyor belt. Multiple layers of test stations may be stacked on top of each other for improved test throughput.
