METHOD FOR PRODUCING ELECTROLYTIC COPPER FOIL, ELECTROLYTIC COPPER FOIL PRODUCED BY THE METHOD, SURFACE-TREATED ELECTROLYTIC COPPER FOIL OBTAINED BY USING THE ELECTROLYTIC COPPER FOIL, COPPER-CLAD LAMINATE USING THE SURFACE-TREATED ELECTROLYTIC COPPER FOIL, AND PRINTED CIRCUIT BOARD

摘要

PROBLEM TO BE SOLVED: To provide an electrolytic copper foil which has a lower profile and a higher gloss than a low-profile electrolytic copper foil that has been conventionally supplied to a market.;SOLUTION: The electrolytic copper foil has a profile with such an ultra-low surface roughness (Rzjis) as less than 1.0 m and a glossiness [Gs (60)] of 400 or higher both on the surface in the deposition side regardless of its thickness. The electrolytic copper foil is obtained by electrolyzing a sulfuric-acid-based cupric electrolyte solution containing 3-mercapto-1-propane sulfonate, and/or bis(3-sulfopropyl)disulfide, a polymer of a quarternary ammonium salt having a cyclic structure, and chlorine.;COPYRIGHT: (C)2007,JPO&INPIT
