A PCB assembly which allows economical and reliable rework. The PCB assembly contains a soldermask and a trace with a portion of the trace exposed by a soldermask relief. When one needs to rework the PCB assembly, one bonds a rework wire, using conventional intermetalic bonding materials, to the portion of the trace exposed by the soldermask relief. There is no need to bond a rework wire to a component. Further, there is no need to scrape off the soldermask and possibly damage the traces and/or vias. The bonds are high reliability bonds, and the labor required to perform such bonds are minimal.
