南京无线电元件17厂革新成功塑封台面硅整流二极管引线以锡代银电镀工艺,每生产100万只管子可节约白银近10公斤.过去,生产塑封二极管引线都是用裸铜线作基材,进行镀银.这种工艺要耗费大量白银,产品成本高,合格率低.为此,该厂组织有经验的技术人员和工人进行攻关,经100多次单项试验和三大批全过程试验,多次改进电镀液配方,终于试验成功用锡代银电镀引线新工艺.目前,用这种工艺已生产100多万只管子,这些
Nanjing radio components plant 17 successful innovation Plastic table top silicon rectifier diode lead tin silver plating process, each production of 1 million tubes can save silver nearly 10 kg. In the past, the production of plastic diode leads are used bare copper substrate, carried out Silver-plated. This process to spend a lot of silver, high product costs, low pass rate.To this end, the plant has experienced technical staff and workers to tackle the problem, after more than 100 single test and three large batch of the whole process of testing, Improve the plating solution formula, and finally test the successful use of tin silver plating lead new technology. At present, with this technology has produced more than 100 million tubes, these
