FABRICATION METHOD OF PRINTED CIRCUIT BOARD

摘要

A manufacturing method of a PCB is provided to form fine roughness on a surface of a board with manufacture of the board by forming fine unevenness on an inner surface of a mold. A fine unevenness is formed in an inner surface of a mold(S110). A thermoplastic material of a powder or molten state is filled inside the mold(S120). The thermoplastic material inside the mold is compression-molded or is injection-molded. A roughness corresponding to the fine unevenness is transferred on a surface of a board(S130). A circuit line is formed on a surface of the board(S140). The thermoplastic material is one among liquid crystal polymer, polyetherimide, polyethersulfone, polyetheretherketone, and polytetrafluorethylene.
