  • Patent number: 8535547
    Abstract: A printed circuit board manufacturing system and a manufacturing method thereof are disclosed. A method of manufacturing printed circuit board, comprising: providing a substrate that comprises a pad and an insulation layer covering the pad; acquiring an image of the substrate; acquiring location information of the pad by analyzing the image of the substrate; forming a via hole by removing a part of the insulation layer that corresponds the location information of the pad; and forming a via by filling the via hole with a conductive material, provides improved process conformity, even if the substrate has partial or nonlinear deformation, by considering the location information of the pad in the via hole forming. The improved conformity may allow more flexibility to substrate design and more integrity for circuitries on printed circuit board.

  • Publication number: 20090027864
    Abstract: A printed circuit board and a method of manufacturing the printed circuit board are disclosed. A printed circuit board, which includes an insulation layer, a circuit pattern formed on a surface of the insulation layer that includes at least one pad, and a solder resist which covers the circuit pattern, and in which an opening is formed that exposes a portion of a side and a surface of the pad, can ensure a sufficient amount of attachment area for the pads and the solder resist, to strengthen the adhesion of the pads. Also, the adhesion can be increased between the electronic components and the printed circuit board, and heat release characteristics can be improved.
