Patent ID: 6922049

Claim:
A testing method for a printed circuit board, said testing method comprising: (A) forming first and second conductive traces on a board body of the printed circuit board, the first and second conductive traces being configured for transmitting a high-frequency differential signal and having segments parallel to each other, each of the segments having opposite first and second ends, an inner edge extending continuously between the first and second ends of a respective one of the segments and that is proximate to the segment of the other of the first and second conductive traces, and an outer edge extending continuously between the first and second ends of the respective one of the segments and that is distal from the segment of the other of the first and second conductive traces, the inner edges of the segments of the first and second conductive traces having a uniform distance maintained therebetween; and (B) forming a pair of conductive pads on the board body of the printed circuit board, each of the conductive pads being disposed between the first and second ends of a respective one of the segments, and being disposed proximate to and being connected electrically to the outer edge of the respective one of the segments.
