Abstract

The present invention provides a method of manufacturing a printed circuit board. The method includes the steps of preparing an insulating substrate having a front surface and a back surface and a layer of metal foil formed on each of the front surface and the back surface; selectively forming a plating layer for forming a land on at least one of the metal foils; adjusting a thickness of the plating layer; and forming the metal foils into lines.
