ABSTRACT:
A method and apparatus for extending the useful life of an aqueous acid chloride solution that serves as a protective bath for an activator dip bath such as used in electroless copper plating. Means are provided for recirculating the acidic chloride solution over metallic tin to precipitate copper ions from the solution. The precipitated copper is filtered from the solution to extend its useful life.
