  • Patent number: 7737367
    Abstract: Holes having the same diameter as via holes are formed in predetermined positions in advance when forming wiring patterns on releasable carriers. The carriers with the wiring patterns are bonded on an insulating material, and a laser beam is irradiated from the side of the carrier using the holes in the wiring pattern as a laser mask to form via holes in the insulating material. The via holes and the holes in the carrier are then filled with a conductive paste. With the holes in the carrier that are matched in position with the via holes, lands in the conductor layers are precisely positioned relative to the via holes. A multilayer circuit board thus produced has lower electrical connection resistance and excellent mountability with improved performances. Also a manufacturing method thereof is achieved.
