Apparatus and method for reworking printed wire circuit boards.

摘要

A flexible applique or patch (30) is used to modify a circuit board (10) by attaching the flexible applique to the back side of a circuit board needing rework. The flexible applique has circuit paths (28') on both its front and back side. The flexible applique also has circuit paths which pass from the front side to the back side of the applique or patch. If additional electrical components are required by the rework, the back side of the applique or patch is provided with pads to which surface mount electrical components are easily attached. Implementing the rework using the applique or patch is simple and easy. The front side of the patch is positioned on the back side of the circuit board, and then attached to the back of the circuit board either by soldering down points along the edge of the patch or by providing an adhesive on the front side of the patch. Using this method, both simple and complex reworks can be quickly accomplished. <IMAGE>
