Patent ID: 7154048

Claim:
A common electrode line for plating for collectively forming conductive patterns of a plurality of circuit substrates on a main substrate, and for plating the conductive patterns of the plurality of circuit substrates at the same time by the common electrode line for plating, said main substrate having a cut line for dividing one and the other circuit substrates and a plurality of through holes formed in said one and the other circuit substrates along the cut line, said common electrode line for plating comprising: first common electrode lines formed on one side of the main substrate, each of said first common electrode lines extending from one through hole formed in said one circuit substrate to one through hole formed in the other circuit substrate while crossing the cut line, and second common electrode lines formed on the other side of the main substrate, each of said second common electrode lines extending from said one through hole formed in said one circuit substrate to another through hole formed in the other circuit substrate next to said one through hole of the other circuit substrate while crossing the cut line, wherein said first and second common electrode lines formed on said one and the other sides of the main substrate are meandering lines.
