ELECTROLYTIC COPPER FOIL WITH CARRIER FOIL AND ITS PRODUCING METHOD, AND COPPER CLAD LAMINATED BOARD USING THE ELECTROLYTIC COPPER FOIL WITH CARRIER FOIL

摘要

PROBLEM TO BE SOLVED: To provide an electrolytic copper foil with carrier foil for producing a printed board with which peeling strength between the carrier foil and the electrolytic copper foil layer can properly be secured, even after press-working at high temperature, such as 250C.;SOLUTION: In the electrolytic copper foil with the carrier foil provided with a joining boundary layer on one side of the carrier foil C and the electrolytic copper foil layer CF on this joining boundary layer, this joining boundary layer is made of chromium compound-base joining boundary layer 2 composed of chromium oxide, chromium hydroxide, and a chromate. This electrolytic copper foil 1a is provided with the joining boundary layer 2 on its one side.;COPYRIGHT: (C)2004,JPO
