METHOD FOR PROCESSING A COPPER BEAM FOR PRINTED CIRCUIT BOARD

摘要

PURPOSE: A method for processing a copper beam for a printed circuit board is provide to prevent damage to the printed circuit board which in inserted into a roller by providing a reinforcing frame to the printed circuit board. CONSTITUTION: A method for processing a copper beam for a printed circuit board is comprised of the following steps: forming a dummy copper film(20') along the edge of a substrate core; masking to expose only the dummy copper film formed along the edge of the substrate to the outside; plating copper on the exposed dummy film to form a copper beam(45); and spreading solder resist(100) after exfoliating the mask.
