Abstract

IN THE STEP OF ADHERING A COVER LAY TO A FLEXIBLE CIRCUIT MEMBER IN THE MANUFACTURE OF FLEXIBLE (OR RIGID FLEXIBLE) PRINTED CIRCUIT BOARDS, THE INVENTION PROVIDES THE IMPROVED RELEASABILITY AND MOLDABILITY THAT CANNOT BE OBTAINED WITH THE CONVENTIONAL RELEASE FILMS, IN THE STEP OF PRESSING, WHILE GOOD SHAPE-FOLLOWING CHARACTERISTICS, UNIFORM MOLDING CHARACTERISTICS AND PLATING CHARACTERISTICS AS WELL AS GOOD CHARACTERISTICS WITH RESPECT OF APPEARANCE WRINKLING ON FINISHED EPCs ARE RETAINED.THE INVENTION PROVIDES A RELEASE FILM WHICH COMPRISES A RELEASE LAYER COMPRISING A THERMOPLASTIC RESIN WHOSE VISCOELASTICITY MODULUS AT THE TEMPERATURE 180°C IS 50 TO 250 MPa. A POLYBUTYLENE TEREPHTHALATE-BASED RESIN IS PREFERRED AS THE THERMOPLASTIC RESIN. THE RELEASE FILM PREFERABLY HAS A CUSHION LAYER PROVIDED ON ONE SIDE OF THE RELEASE LAYER AND COMPRISING A THERMOPLASTIC RESIN OTHER THAN THAT OF THE RELEASE LAYER. PREFERABLY, THE RELEASE LAYER IS EMBOSSED WITH A SPECIFIC ROUGHNESS. THE INVENTION ALSO PROVIDES A METHOD OF MANUFACTURING FLEXIBLE AND RIGID FLEXIBLE PRINTED CIRCUIT BOARDS WHICH UNTILIZES THE RELEASE FILM SPECIFIED ABOVE.
