  • Test fixture with permanent circuit board extractor thereon
    Patent number: 5446394
    Abstract: A circuit board extractor particularly suitable for extracting "burn-in" boards from a test fixture is attached to the front of the test fixture between the tester connector assembly and the burn-in board, or burn-in board frame rails, for movement of a movable member between first and second positions. The first position of the movable member occurs when the pin connectors on the edge of the burn-in board are inserted into corresponding pin receptacles on the front of the test fixture. Movement of the movable member from the first position thereof to its second position pushes the burn-in board away from the front of the test fixture to cause withdrawal of the pin connectors on the edge of the burn-in board from the pin receptacles on the edge of the test fixture without damaging the burn-in board or the test fixture.
