PURPOSE: A plating method and structure are provided to improve the adhesion of a CuCN layer plated in the surface of a CuCN strike layer by forming a smooth aluminum surface through strike plating. CONSTITUTION: A plating method comprises the steps of: preparing a seed layer(110), plating a metallic coating layer on the seed layer, plating a first chrome layer(160) using chrome chloride liquid on the metallic coating layer, and plating a second chrome layer(170) using chromium sulfate liquid on a chrome chloride layer. The seed layer includes a CuCN layer(140) for plating of the metallic coating layer.
