ABSTRACT:
The present invention relates to an addition to tin coating solutions for inhibiting the growth of tin whiskers. The addition comprises a concentration of a metal salt selected from the group consisting of palladium salt, silver salt, nickel salt, iron salt, cadmium salt, platinum salt, gold salt, indium salt, ruthenium salt and cobalt salt. In a preferred embodiment, the metal salt addition is either a palladium salt such as palladium chloride or a silver salt such as silver sulfate.
