ABSTRACT:
A system for reducing the number of points to be tested on a dual sided printed circuit board. The circuit board includes a top and a bottom surface and a plurality of network traces extending across both sides of the printed circuit board. Each network trace includes end points. The system provides for identifying the end points of a network trace extending on both sides of the printed circuit board. The mid-point along the network trace which is common to both sides of the printed circuit board is identified. Structure is provided for independently testing each side of the printed circuit board between one end point and the mid-point on the top surface of the printed circuit board and between the mid-point and the second end point on the bottom surface of the printed circuit board.
