Patent ID: 8918991

Claim:
A method for providing an electrical connection between traces disposed on different layers of a circuit board, the method comprising: forming in the circuit board a via hole that interconnects a pair of electrically conductive traces disposed on different layers of a circuit board, wherein an inner sidewall of the via hole includes electrically conductive material thereon, and wherein the via hole extends between the different layers; and removing a first portion of the electrically conductive material from the inner sidewall by removing a first portion of the inner sidewall, wherein, after removing the first portion of the inner sidewall, a remaining portion of the electrically conductive material on a remaining portion of the inner sidewall interconnects the pair of electrically conductive traces, and wherein the remaining portion of the electrically conductive material has a corresponding width that is substantially similar to a width of each electrically conductive trace of the pair of electrically conductive traces.
