PRINTED CIRCUIT BOARD AND SUBSTRATE FOR PRINTED CIRCUIT BOARD AND METHOD OF MANUFACTURING AND SUBSTRATE FOR PRINTED CIRCUIT BOARD

摘要

PURPOSE: A printed circuit board, a substrate material using the same, and a method for manufacturing thereof are provided to improve hole workability of the substrate material by improving laser absorbing rate of glass fiber. CONSTITUTION: Glass fiber(111) is impregnated in a resin layer(113). The glass fiber comprises fiber and absorbing material including glass. The glass fiber increases the intensity of a printed circuit board in regard to a bending phenomenon. The absorbing material absorbs laser. The absorbing material is coated in the glass fiber. The absorbing material includes one among triazene, arbodiimide, and ester or carbonate. A substrate material comprises the absorbing material. A circuit pattern is formed on the surface of the substrate material.
