ABSTRACT:
A tool is described for facilitating the cutting of printed circuit board wires necessitated by changes in the circuit design or the occurrence of electrical faults. The tool is particularly useful with circuit boards having high density wiring, where it virtually eliminates damage to printed wires adjacent to those being severed. Comprised of a guide pin centrally disposed with respect to an annular cutting edge, the tool uses the former for registration with the component and via holes in the circuit board, and the latter, to sever the printed wires from the electrically conductive pads surrounding the holes. The depth of the cut is carefully controlled by the tool and may be chosen to eliminate electrical faults lying below the surface in a multilayer board.
