Abstract:
A method of producing a surface-treated copper foil for producing printed wiring boards, which method includes a surface-treating method comprising forming a nodular-treated surface on a surface of a copper foil; subjecting the copper foil to anti-corrosion treatment; effecting adsorption of a silane coupling agent onto the nodular-treated surface; and drying, wherein the anti-corrosion treatment comprises performing zinc-copper (brass) plating on a surface of the copper foil; subsequently performing electrolytic chromate treatment; drying a surface of the copper foil after electrolytic chromate treatment; effecting adsorption of a silane coupling agent; and drying the copper foil for 2-6 seconds in a high-temperature atmosphere in which the temperature of the copper foil reaches 105Â° C.-180Â° C.
