Abstract

A method of electrocodeposition of lead free tin alloys is disclosed. The method includes the following steps: electrocodepositing tin metal (10) and particles of a noble metal (12) to form a composite (FIG. 1A); and converting the composite (FIG. 1B) to an alloy (18) by heating the composite.
