    摘要: Disclosed herein is a method of manufacturing a printed circuit board, including: providing a carrier including an insulation layer, first metal foils formed on both sides of the insulation layer, adhesive layers respectively formed on the first metal foils and made of a thermoplastic resin, and second metal foils respectively formed on the adhesive layers; applying resists having openings for forming metal posts onto both sides of the carrier; forming metal plating layers for forming the metal posts in the openings; grinding surfaces of the resists; removing the resist and forming insulation layers on both sides of the carrier; and grinding surfaces of the insulation layers. The method is advantageous in that both sides of a carrier are simultaneously layered, it is possible to prevent a substrate from warping during the process of manufacturing the printed circuit board.
