METHOD FOR MANUFACTURING LAMINATED BODY AND PRINTED- WIRING BOARD

摘要

PROBLEM TO BE SOLVED: To provide a printed-wiring board having excellent adhesiveness, circuit shape and insulation properties between wirings in a laminated body of a polymer and a metal layer which can realize the printed-wiring board with a high density by a semi-additive method. SOLUTION: The laminated body comprises a first metal layer of nickel or a nickel alloy formed on a surface of a polymer film with a smooth surface by a physical technique, a second metal layer prepared by an electroless nickel plating and a third metal layer by an electric copper plating, and it is manufactured by using an etching liquid in which an etching speed of nickel or the nickel alloy is at least twofold of the etching speed of copper and nickel or its alloy is selectively etched when the first and second metal films are etched.
