Patent abstract
This invention relates to a method of manufacturing a printed circuit board, in which a dummy metal frame enclosing the outer periphery of a product part is formed, thus simultaneously assuring the rigidity of the printed circuit board and minimizing the warping thereof thanks to the dummy metal frame left in place on a finished product, thereby realizing a structure compatible with conventional flip chip mounting lines.
