Abstract
A polyphenylene sulfide (PPS) molded board reinforced with 15-85 wt. % of glass fibers (GF) having a length of at least 5 mm is provided. The molded board is useful as an insulating substrate of a printed circuit board. The printed circuit board is prepared by compressing under heating a mixture or laminate of PPS and GF to form a composite molded board and, at or after the compression step, bonding a metallic foil to a surface the composite molded board. The printed circuit board is excellent in mechanical properties such as impact resistance, thermal properties such as heat distortion temperature and solder resistance, and adhesion between the insulating substrate and the metallic foil.
