Abstract:
A printed wiring board production method that forms a base film and a conductive pattern on the base film by an additive method or a subtractive method, includes a plating process that electroplates the conductive pattern on a surface of the base film, wherein the plating process includes a shield plate arranging process that arranges a shield plate between an anode and a printed wiring board substrate that forms a cathode, and a substrate arranging process that arranges the printed wiring board substrate in a plating tank, and wherein a distance between the shield plate and the printed wiring board substrate is 50 mm or greater and 150 mm or less.
