Abstract: Printed circuit board assemblies must be tested before being sold to consumers. Yet, the assemblies have various shapes and input/output configurations. Thus, a need exists for a general apparatus and method for testing a variety of assemblies. The present tester uses a test enclosure which contains the necessary test electronics. The front of the enclosure includes a personality board which is designed to interface with the device under test.

Abstract: A method for testing printed circuit boards (PCBs). The PCBs are initially transported to a reorienting apparatus that aligns the PCBs to accommodate automated test equipment (ATE). The ATE consists essentially of two stations interconnected by a conveyor. At the first station testing of PCBs occurs sequentially at two test wells that are vertically movable between respective idle and testing positions. Upon being discharged from the first test station, a predetermined number of PCBs are concatenated along the conveyor that connects the first test station to the second test station. The concatenated PCBs are delivered to the second test station that simultaneously performs a second test on the predetermined number of PCBs. Inasmuch as the first test is of a duration substantially shorter than the second test, the concatenation of a number of PCBs prior to performance of the second test compensates for the difference in respective durations.
