Abstract
A circuit board film-plated against corrosion of conductive traces comprises a substrate, at least one conductive circuit layer attached to the substrate, at least one plating film attached to a surface of the conductive circuit layer away from the substrate, and a covering film. Each of the at least one plating film comprises a surface away from the conductive circuit layer, and at least one side surface. The circuit board defines at least one through hole. Each of the at least one through hole passes through substrate, conductive circuit layer, and the plating film. The covering film covers the conductive circuit layer, the side surface of the plating film, and the through hole. The film-covered conductive circuit layer and the film-covered side surface of the plating film cannot be corroded. A method for making the circuit board is also provided.
