  • Patent number: 10273591
    Abstract: A flux composition which includes one or more organic compounds including one or more sulfonic acid groups, salts or anhydrides thereof is applied to tin or tin alloy deposits. The flux composition is then homogenized on the tin or tin alloy to inhibit tin or tin alloy oxidation and improve brightness of the tin or tin alloy.
