Method of Manufacturing Printed Circuit Board Base Sheet, Method of Manufacturing Printed Circuit Board, and Printed Circuit Board

摘要

A printed circuit board base sheet is manufactured by laminating an insulating resin film and a metal foil using a laminate roller. A rustproofing layer containing chromium is formed on a surface of the metal foil. The temperature of the laminate roller is set to 330 to 390° C. A time period during which the metal foil and the laminate roller are brought into contact with each other immediately before a contact time point between the insulating resin film and the metal foil is set to 0.5 to 4.0 seconds.
