Abstract: The present invention relates to a printed circuit board including: a substrate; a circuit pattern formed on a surface of the substrate; a dummy pattern formed on the surface of the substrate, where the circuit pattern is not formed, to be spaced apart from the circuit pattern by a predetermined interval; and a plurality of heat radiating vias formed along an outer edge of the substrate to electrically connect the dummy patterns through the substrate, and it is possible to suppress generation of electromagnetic waves or shield the electromagnetic waves and improve heat radiating characteristics at the same time.

Abstract: Disclosed herein is a method for manufacturing a multilayer circuit board, and more particularly, is a method for manufacturing a coreless multilayer circuit board that forms a support including a separating layer made of a thermoplastic resin and allowing the support to be simply separated, thereby being advantageous in processing a subsequent process, regardless of a size of the board, and economical in the manufacturing process of the support and the manufacturing costs thereof.
