  • Publication number: 20120320540
    Abstract: A printed circuit board of a card edge connector type includes interconnections formed on a surface of a substrate to be electrically coupled to respective connecting terminals formed by electrolytic plating on an edge of the substrate, and connecting terminal-forming wirings being respectively in connection with the interconnections, when the connecting terminals are formed by the electrolytic plating. The interconnections are electrically isolated from the connecting terminal-forming wirings by process openings formed in the substrate.
