| titleOfInvention | Copper foil for printed circuit board and copper-clad laminate for printed circuit board |
| abstract | Disclosed is a copper foil for printed circuit boards which comprises a copper foil and, deposited on a surface thereof, a layer comprising nickel, zinc, and copper (hereinafter, referred to as "copper-nickel-zinc layer"), characterized in that the amount of deposited zinc in the copper-nickel-zinc layer is 200-2,000 [μ]g/dm2 and that in the copper-nickel-zinc layer, the amount of Ni is 1-50 wt.%, (amount of deposited zinc (mass%))/{100-(amount of deposited copper (mass%))} is 0.3 or more, and (amount of deposited copper (mass%))/{100-(amount of deposited zinc (mass%))} is 0.3 or more. A method for treating a surface of a copper foil has been established with which it is possible to effectively prevent a circuit erosion phenomenon that occurs when a copper foil laminated to a resin base is subjected to soft etching of a circuit with a sulfuric acid/hydrogen peroxide etchant. |
