  • Publication number: 20120061710
    Abstract: A method for treating a metal surface to reduce corrosion thereon and/or to increase the reflectance of the treated surface, the method comprising a) plating a metal surface with an electroless nickel plating solution; and thereafter b) immersion plating silver on the electroless nickel plated surface, whereby corrosion of the metal surface is substantially prevented and/or the reflectance of the silver plated surface is substantially improved. The treating method is useful for increasing the solderability of the metal surface, for example, in electronic packaging applications.

  • Publication number: 20120061698
    Abstract: A method for treating a metal surface to reduce corrosion thereon and/or to increase the reflectance of the treated surface, the method comprising a) plating a metal surface with an electroless nickel plating solution; and thereafter b) immersion plating silver on the electroless nickel plated surface, whereby corrosion of the metal surface is substantially prevented and/or the reflectance of the silver plated surface is substantially improved. The treating method is useful for increasing the solderability of the metal surface, for example, in electronic packaging applications and in manufacturing light emitting diodes (LEDs).

  • Patent number: 7416763
    Abstract: A process in which a base metal film is formed on the surface of a plastic film using a dry plating process, and a liquid containing an organic monomer is then brought in contact with the base metal film, thereby selectively forming a conductive organic polymer coating within any pinhole defects, and effectively filling the defects. A metal film is then formed on top of the base metal film using an electroplating process, thus forming a metal wet plating layer.

  • Publication number: 20080023218
    Abstract: A novel electrolytic plating method suitable for filling non-through holes with metal is disclosed. The electrolytic plating method uses a plating solution containing additives such as a surfactant, a brightening agent and a smoothing agent and includes pulse plating for controlling adsorption and desorption of tie additives on the surface and in the non-through holes of substrate and subsequent DC plating for filling up the non-through holes with metal.
