    Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing a printed circuit board for a semiconductor package capable of simplifying steps and improving mounting reliability, by eliminating all of a masking process or minimizing it on plating each pad in a surface processing operation of the printed circuit board for the semiconductor package.
    SOLUTION: A printed circuit board for packaging is provided including a certain circuit pattern formed thereon including pads for wire bonding and for SMD mounting. A solder resist layer is formed in a part except for the pads for wire bonding and for SMD mounting of the printed circuit board. Nonelectrolytic nickel and gold plating layers are formed on the pads for wire bonding and for SMD mounting by means of a nonelectrolytic nickel plating and a nonelectrolytic gold plating. An electrolytic gold plating layer is formed by means of the electrolytic gold plating, on a part of an ENIG layer with a plating lead wire connected thereto in the ENIG layers of the pad for the SMD mounting, and on the ENIG layer of the pad for wire bonding.
