Abstract: A printed circuit board, especially for a computer keypad, and method for avoiding electromagnetic interference include conductive signal traces positioned on a surface of one of a nonconductive layer that is other than the outward facing surface of an outer nonconductive layer, and vertical interconnect accesses extending through the outer nonconductive layer and connecting the signal traces to the outward facing surface of the outer nonconductive layer, wherein each vertical interconnect access includes a conductive portion on the outward facing surface of the outer nonconductive layer, and the conductive portion has an area no greater than 1/10 the area of the asociated signal trace. Keys selectively connect pairs of vertical interconnect accesses.
