Abstract

Disclosed are systems and methods of plating a tin alloy in an efficient, economical, and environmentally friendly manner. An electrochemical cell containing an anolyte compartment and a catholyte compartment separated by a selective membrane is employed. The selective membrane prevents ionic metals from migrating from the catholyte compartment to the anolyte compartment. A conduit may be employed in the electrochemical cell to permit one way flow of anolyte to the catholyte compartment thereby replenishing tin to the catholyte compartment.
