PRINTED CIRCUIT BOARD

摘要

The present invention relates to a printed circuit board capable of minimizing the thickness of the printed circuit board and protecting a circuit pattern by constituting the circuit pattern of the printed circuit board to be embedded in a surface of an insulating layer. The printed circuit board of the present invention comprises: an insulating layer; and first and second external circuit patterns embedded in one surface and the other surface of the insulating layer respectively. The insulating layer additionally includes a groove, and the first and second external circuit patterns are formed in the groove.
