摘要： A method of manufacturing a circuit board is disclosed. The method may include: forming a relievo pattern, which is in a corresponding relationship with a circuit pattern, on a metal layer that is stacked on a carrier; stacking and pressing the carrier onto an insulation layer with the relievo pattern facing the insulation layer; transcribing the metal layer and the relievo pattern into the insulation layer by removing the carrier; forming a via hole in the insulation layer on which the metal layer is transcribed; and filling the via hole and forming a plating layer over the metal layer by performing plating over the insulation layer on which the metal layer is transcribed. As the relievo pattern may be formed on the metal layer stacked on the carrier, and the relievo pattern may be transcribed into the insulation layer, high-density circuit patterns can be formed.

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.
