摘　　要：镀后处理是防止功能性镀锡层氧化变色、可焊性下降的有效手段。镀后热处理技术可以有效改善镀层的微观结构,而锡层表面的物理或化学处理可以有效保持镀层功能性,提高应用的可靠性。通过物理和化学两个角度对镀锡层的后处理技术进行了总结,并对后处理技术的发展进行了展望。The post-treatment after plating is an effective means to prevent the oxidation discoloration of functional tin plating and the decrease of weldability.Heat treatment after plating can effectively improve the microstructure of the tin plating,and physical or chemical treatment on the surface of the tin plating can effectively maintain the plating function and improve the reliability of the application.The post-treatment technology of tin plating was summarized from both physical and chemical perspec‐tives,and the development of post-treatment technology was prospected.
