METHOD OF MACHINING FILM BASE MATERIAL AND FILM BASE MATERIAL MACHINING APPARATUS

摘要

A method of machining a film base material and film base material machining apparatus that involve measures for any unwanted matter generated by removal machining. The method comprises the removal machining step of perforating a film base material and the hot melting step of hot melting the film base material by the use of laser beams so that any unwanted matter (burr and cutting piece) generated by the perforation is sealed within the film base material.
