. Most fabrication shops require a minimum annular ring of 0.35 mm (15mil) over the hole size. Making the plane anti-pad annular ring smaller couldcause the drill hole to be too close to the copper plane and making it largerremoves important plane copper that carries the signal return path fortransmission lines
