    Abstract: A method of treating copper foil for use in the production of printed circuit boards to improve the adhesion of the foil to a base material includes the steps of depositing a nodular or dendritic layer of metal such as copper or zinc onto the foil and encapsulating said nodular or dendritic layer of metal with a layer of copper. A barrier layer is deposited over said encapsulating layer of copper, the barrier layer comprising an alloy of zinc, nickel and one or more of the metals lead, selenium, tellurium, tin or arsenic, the resultant structure then being passivated.
