  • Composite dual blackened copper foil and method of manufacturing the same
    Patent number: 8957326
    Abstract: A composite dual blackened copper foil includes a copper foil and two blackened layers. The copper foil has a shiny side and a matte side. The blackened layers are formed on the shiny and matte sides respectively. The blackened layers are formed alloy by electroplating in a plating bath consisting essentially of copper, cobalt, nickel, manganese, magnesium and sodium ions. A rough layer is selectively formed between the blackened layer and the shiny side as well as the matte side. Both side of the copper foil is spotless, powder free, and good in etching quality. The copper foil is effective at blocking electromagnetic wave, near infrared, undesired light and the like. The copper foil exhibits strong light absorption and is applicable to direct gas laser drilling. A method of manufacturing the composite dual blackened copper foil is also provided.
