Patent ID: 8043514

Claim:
A method of manufacturing a wiring board by utilizing electroplating, comprising: forming a first electroless plating layer on a surface of a large-sized insulating substrate; forming a first plating resist pattern on the first electroless plating layer; forming a first electroplating layer on the first electroless plating layer exposed from the first plating resist pattern by supplying an electric power from the first electroless plating layer, to define a wiring pattern without forming the wiring pattern on a peripheral edge of the wiring board; removing the first plating resist pattern; forming a second plating resist pattern so that a first predetermined portion of the wiring pattern is exposed; forming a second electroplating layer on a first predetermined portion of the wiring pattern by supplying an electric power from the first electroless plating layer, to define the wiring pattern without forming the wiring pattern on a peripheral edge of the wiring board; removing the second plating resist pattern; removing portions of the first electroless plating layer exposed from the wiring pattern; and forming a solder resist pattern so that a predetermined portion including the first predetermined portion of the wiring patterns is exposed, wherein the wiring board is individually obtained by cutting the large-sized insulating substrate along cutting lines, wherein said forming of the first electroplating layer is carried out by supplying electric power from a part of the first electroless plating layer exiting on a peripheral edge of the large-sized insulating substrate, wherein said forming of the wiring pattern is carried out in such a manner that the wiring patterns do not extend to the cutting line at an edge of the individual wiring board, and wherein said forming of the second electroplating layer is carried out by supplying electric power from the part of the first electroless plating layer exiting on the peripheral edge of the large-sized insulating substrate.
