BVH METHOD FOR MANUFACTURING FLEXIBLE PRINTED CIRCUIT BOARD WITH BVH

摘要

A flexible printed circuit board manufacturing method is disclosed, wherein the flexible printed circuit board manufacturing method comprises: (a) a first laminate and a second laminate including a polyimide layer and copper layers formed on both surfaces of the polyimide layer; processing bvh on one side; (b) the first laminate and the second laminate so that one surface of each of the first and second laminates processed by bvh faces one side and the other side, and the other surfaces face each other with a tape interposed therebetween and laminating a tape to prepare a main laminate in which the bvh is processed on one side and the other side; (c) applying chemical copper to one surface and the other surface of the main laminate; (d) performing copper plating on one surface and the other surface of the main laminate; (e) patterning one surface and the other surface of the main laminate; (f) laminating an outer layer on one surface and the other surface of the main laminate; and (g) separating the main laminate into the first and second laminates, wherein steps (a) to (e) are performed by a roll-to-roll method.
