METHOD FOR FABRICATING PCB AND PCB FABRICATED THEREBY

摘要

PURPOSE: A method for fabricating a PCB(Printed Circuit Board) and a PCB fabricated thereby are provided to remove a dummy line and enhance the efficiency by performing a patterning process on a mandrel. CONSTITUTION: A metallic material is plated on a mandrel of a substrate(5) on which patterns are formed. A metallic conductive line(3) is formed by plating the metallic material on the mandrel. A metal layer or a polymer layer is formed or the metal layer and the polymer layer sequentially formed on the substrate(5) in order to enhance the adhesive strength. The polymer is coated on the metallic conductive line(3). A dry process is performed to dry the polymer. The mandrel is removed. The mandrel is formed with one of stainless steel, aluminium, and nickel.
