Testing method for a printed circuit board formed with conductive traces for high-frequency diferential signal transmission

摘要

A testing method is provided for a printed circuit board that includes a board body formed with first and second conductive traces thereon. The first and second conductive traces are configured for transmitting a high-frequency differential signal and have segments parallel to each other. Each of the segments has an inner edge proximate to the segment of the other of the first and second conductive traces, and an outer edge distal from the segment of the other of the first and second conductive traces. Each of a pair of conductive pads formed on the printed circuit board is disposed proximate to and is connected electrically to the outer edge of the segment of a respective one of the first and second conductive traces.
