ABSTRACT:
Methods and devices are provided for repairing a damaged contact pad that is located on a first surface of a printed circuit board and connected to a via that passes through the circuit board. According to the method, a countersink hole is created in the first surface of the printed circuit board in a location that is substantially centered on an axis passing through the via, and a replacement structure is inserted into the countersink hole. The replacement structure has a stem portion, a head portion, and a shoulder portion that connects the stern and head portions, with the angle of the shoulder portion substantially matching the angle of the shoulder of the countersink hole. The stem portion of the replacement structure is permanently attached to sidewalls of the via so as to electrically couple the head portion of the replacement structure to the via.
