  • Metal alloy sulfate electroplating baths
    Patent number: 6562220
    Abstract: The use of alkali metal, alkaline earth metal, ammonium and substituted ammonium salts of alkyl and alkanol sulfonic acids as additives in pure metal and metal alloy sulfate electroplating baths has a number of unexpected benefits including wider useful current density range, improved appearance and in the case of tin improved oxidative stability. The metals and alloys include but are not limited to tin, nickel, copper, chromium, cadmium, iron, rhodium, ruthenium, iron/zinc and tin/zinc.
    Type: Grant
    Filed: May 21, 2001
    Date of Patent: May 13, 2003
    Assignee: Technic, Inc.
    Inventors: Hyman D. Gillman, Brenda Fernandes, Kazimierz Wikiel

  • Metal alloy sulfonic acid electroplating baths
    Patent number: 6183619
    Abstract: The use of alkali metal, alkaline earth metal, ammonium and substituted ammonium salts of alkyl and alkanol sulfonic acids as additives in pure metal and metal alloy sulfonic acid electroplating baths has a number of unexpected benefits including wider useful current density range, improved appearance and in the case of tin improved oxidative stability. An additional significant appearance is to reduce the overall costs of this type of bath with the more economical salts of alkyl and alkanol sulfonic acids. The metals and metal alloys include but are not limited to tin, lead, copper, nickel, zinc, tin/lead, tin/lead/copper, tin/zinc and zinc/nickel.
