  • Publication number: 20100116674
    Abstract: Methods are disclosed for replenishing tin and its alloying metals in an aqueous electrolytic plating bath using an acidic solution containing stannous oxide. During electroplating of tin or tin alloys the stannous ions and alloying metal ions are depleted. To maintain continuous and efficient electroplating processes predetermined amounts of the plating bath containing tin and its alloying metals are bailed out. The bail out is then mixed with a predetermined amount of acidic solution containing stannous oxide and any alloying metals. The mixture is then retuned to the plating bath to return the stannous ions and alloying metal ions to their steady state concentrations.
