Abstract

A printed circuit board having improved vias for improving signal transmission characteristic by reducing reflections of input signals includes a first signal layer, a second signal layer, one via, a plurality of input signal traces arranged on the first signal layer and a plurality of output signal traces arranged on the second signal layer. The via includes a drill hole and two pads. One of the pads is electrically connected with the input signal traces, and the other of the pads is electrically connected with the output signal traces. A diameter of the pad electrically connected with the input signal traces is smaller than a diameter of the pad electrically connected with the output signal traces.
