Fan Hong;Ma Xiaoxia;Liu Xiyun;Li Yuqin;Du Jinfeng;Yantai Zhaojin Kanfort Precious Metals Incorporated Company;Shenhua Guohua Electric Power Research Institute(Beijing) Co.,Ltd.;  
This paper described the preparation process of Ag alloy bonding wire with 94 %-96 % Ag.The surface microstructures before and after bonding were observed by scanning electron scope and stereomicroscope.The paper discussed the effect of annealing temperature on mechanical properties and the effect of arc length on electric properties,arrived at the mechanical performance standard of the silver alloy bonding wire,and compared it with imported products.The results show that the mechanical,electric and bonding properties are all good.
