Abstract
A circuit board comprises a substrate with opposite first and second sides. A pair of plated through holes (PTHs) extends along z-axis. A pair of signal traces are made on the first side of the substrate and electrically coupled to the pair of the PTHs respectively to form a differential pair. A ground metal is made on the second side of the substrate, the ground metal has a clearance made therein. The ground metal extends fully overlapping with the full signal traces to eliminate reflection noise caused by a boundary between the clearance and the metal ground.
