  • Publication number: 20150240375
    Abstract: Cyanide-free acidic silver electroplating compositions include one or more acids or salts of tellurium and may be used to electroplate matte silver deposits on metals, such as nickel, copper or copper alloys. Matte silver metal may be electroplated at conventional plating rates or at high plating rates, such as in reel-to-reel and jet plating. The cyanide-free acidic silver electroplating compositions may be used to electroplate matte silver in the manufacture of electronic components such as electrical connectors, finishing layers for metallic substrates, optical devices and decorative applications.

  • Patent number: 6773568
    Abstract: The present invention provides inter alia electroplating compositions, methods for use of the compositions and products formed by the compositions. Electroplating compositions of the invention are characterized in significant part by a grain refiner/stabilizer additive comprising one or more non-aromatic compounds having &pgr; electrons that can be delocalized, e.g., an &agr;,&bgr; unsaturated system or other conjugated system that contains a proximate electron-withdrawing group. Compositions of the invention provide enhanced grain refinement and increased stability in metal plating solutions, particularly in tin and tin alloy plating formulations.
