  • Apparatus and method for testing printed circuit boards
    Patent number: 4947112
    Abstract: Apparatus and method for electrical testing of a printed circuit (PC) board having a circuit layout wherein circuit paths interconnect selected plated through holes and components are mounted on the board by insertion of component leads through predetermined plated through holes in the board. The test apparatus includes a test board having a circuit layout identical to the circuit layout of the PC board. The test board does not have components mounted on it, but has instead test probes extending through predetermined plated through holes on the test board. The test probes are soldered to the circuit paths on the test board establising electrical connections between predetermined test probes via circuit paths on the test board.
