    摘要: A method of manufacturing a printed circuit board is disclosed. Using the method, which includes embedding a first circuit pattern and a second circuit pattern in one side and the other side of an insulation substrate, forming a via hole by removing portions of the insulation substrate and the first circuit pattern, and electrically connecting the first circuit pattern and the second circuit pattern by forming a plating layer in the via hole, it is possible to form high-density circuits, as circuitry may be formed in portions that might have been occupied by lands, and more circuitry may be implemented for a given area of insulation substrate, whereby a fine-patterned printed circuit board may be implemented that has a high degree of integration. Also, a printed circuit board can be produced which allows good signal transfers between layers and with which fine circuit patterns can be implemented with inexpensive costs.
