Copper foil for printed-wiring board and copper-clad laminate using copper foil for printed-wiring board

摘要

The object is to provide a copper foil excellent in the property of selective etching between a resistor layer and a copper layer required in production of a printed-wiring board, and also excellent in UL heat resistance. For this purpose, a copper foil for printed-wiring board comprising a nodular treatment side on one side, wherein a nickel-zinc alloy layer is formed on the nodular treatment side is used for applications of printed-wiring boards. At the same time, a production method suitable for production of the copper foil is provided.
