- Pd Ni deposit contg. about 40wt% Ni has higher hardness,lower porosity,higher corrosion resistance,lower contact resistance and acceptable solderability. It can be used as a substitute for gold coating in electronic industrial applications. 结果表明,在一定的工艺条件下,可以根据需要控制镀液中Ni/Pd来获得不同含镍量的钯镍合金镀层,其含镍量40%25左右的钯镍合金镀层具有较高的硬度、较少的孔隙、较好的耐蚀性及较低的接触电阻、合格的可焊性,因此在电子工业中可以代替硬金镀层。
- The Pd-Ni electroplating bath types and characteristics are comprehensively introduced,the methods improved property of Pd Ni coating to adapt to electron industry are also presented. 综述了钯镍合金常见的镀液类型及其特点,介绍了一些改进和提高镀层质量以适应电子工业技术要求的措施。
