ABSTRACT:
This invention is for an immersion tin plating composition capable of depositing tin over metallic surfaces displaceable by tin and to processes using the same. The composition is characterized by an inhibitor that improves the plating characteristics of the solution and permits an increased ratio of thiourea to tin at a relatively high tin concentration without formation of "black tin". The tin plating compositions of this invention are capable of providing an increased yield of good quality tin compared to prior art tin plating compositions.
