MULTI-LAYER PRINTED CIRCUIT BOARD AND METHOD OF MANUFACTURING THE SAME
Abstract:
Disclosed herein are a multi-layer printed circuit board and a method of manufacturing the same. In the multi-layer printed circuit board and the method of manufacturing the same, circuit layers formed in a plurality of insulating layers are electrically interconnected through vias formed in a lump, thereby making it possible to secure bonding reliability of an interlayer circuit layer and more stably secure performance of the printed circuit board. In addition, since a stacked type via structure may be implemented by performing a via hole drilling process, a desmear process, and a copper plating process only one time after an insulating layer and an circuit layer are stacked, a manufacturing process, a manufacturing time, and manufacturing costs of the stacked type via structure may be reduced.
