Abstract:
A semiconductor device test board comprising:a circuit board for carrying at least one semiconductor device to be tested, the circuit board including wiring for transferring signals and a supply voltage to the semiconductor device; andat least one indicator mounted on said circuit board, associated with one of said semiconductor devices carried by the circuit board, for visually indicating a result of testing of the semiconductor device, the indicator retaining the result of the test after the supply voltage is disconnected from the semiconductor device, the indicator including:an indicator arm rotatably mounted on a first pivot on the circuit board, the indicator arm having a free end and a pivot end;a latch arm rotatably mounted on a second pivot on the circuit board, the latch arm having a free end, a pivot end, and a catch located at the free end of the latch arm, the catch engaging the free end of the indicator arm;exerting means for exerting a force on the indicator arm in a direction for retaining the indicator arm in a rest position engaging the latch arm; andreleasing means for disengaging the latch arm from the indicator arm when a test result of the semiconductor device associated with the indicator indicates a failure in the semiconductor device.
