Abstract:
1. A replacement structure for repairing a damaged contact pad on a printed circuit board, the structure comprising: a head portion with a substantially planar upper surface for electrically and physically contacting an electrical component; a sloping shoulder portion having an angle for substantially matching an angle of a countersink hole in the circuit board, the shoulder portion being connected to the head portion; and a stem portion for insertion into a remaining portion of a via that is in the circuit board below the damaged contact pad, the stem portion being connected to the shoulder portion so that the replacement structure has a generally T-shaped configuration, wherein the sloping shoulder portion slopes at a constant angle from a lower surface of the head portion to an upper surface of the stem portion, and the head portion, shoulder portion, and stem portion combine such that the replacement structure has a length that is substantially equal to the distance from an upper surface of the damaged contact pad through the via to a bottom surface of the circuit board so as not to protrude from the bottom surface of the circuit board.
