ABSTRACT:
A printed wiring assembly rework tool and method which eliminates the need to remove a component from the printed wiring assembly in order to isolate a component pin from one or more printed circuits in the printed wiring assembly. The rework tool is able to mill or cut away a plated through hole and/or the area of the printed wiring assembly immediately surrounding the component pin without removing the component. Using the rework tool, the operation continues until the rework tool has either cut to a sufficient depth in the printed wiring assembly to sever a particular electrical connection, or the tool has cut all the way through the printed wiring assembly in order to completely isolate the component pin. The rework tool includes a pilot hole which accommodates the component pin as the tool cuts into the printed wiring assembly.
