Leaching Behavior of Tin with Oxygen in Recycled Phenolsulfonic Acid Tin Plating Solutions

摘要

Electrolytic tin plating on steel substrate has been widely used in the food and beverage industries due to its non-toxic nature[l].Recently,it also has been applied in the semiconductor industry because of its strong resistance to corrosion and tarnishing of the component leads,solderability and ductility.The purpose of present study was to investigate the dissolution characteristics of tin metal in recycled tin plating solution by electrochemical methods and direct leaching experiments in the presence of oxygen.
