Abstract
A printed circuit board includes a signal layer, a dielectric layer, and a reference layer. The signal layer includes a pair of differential signal lines. The dielectric layer is sandwiched between the signal layer and the reference layer. A first void is defined in the reference layer between projections of the pair of differential signal lines. Two second voids are defined in the reference layer at opposite sides of the projections of the pair of differential signal lines.
