    摘要: A printed circuit board is designed to meet the following requirements. A front-back copper foil residual rate difference a−b falls within a range of −10% to 10%, where the insulative board is divided into a plurality of divisions, in which front and back surface copper foil residual rates of each division are a % and b %, respectively. A difference (a−b)−(c−d) between front-back copper foil residual rate differences of adjacent divisions falls within a range of −10% to 10%, where the front and back surface copper foil residual rates of a division adjacent to the each division are c % and d %, respectively. There are not three or more consecutive divisions for which the difference between the front-back copper foil residual rate differences goes beyond a range of −5% to 5%.
