本文在试验的基础上讨论了几种国产无银钎料的性能及其在电子整机产品中的应用。一、银钎焊在电子整机产品中的应用在电子整机产品中,银钎焊主要用于焊接用铜或铜合金制成的零部件。这些零部件使用条件及焊后的加工情况各不相同,因而对钎缝的要求也不相同。高频元件的波导、腔体等零部件,一般在焊后要进行切削加工或人工修整抛光,然后电镀。这类部件要求焊后变形小,加工尺寸的精度及表面精度
Based on the experiment, this paper discusses the properties of several domestic silver-free solder and its application in electronic machine products. First, the silver brazing in the application of electronic machine products In the electronic machine products, silver brazing is mainly used for welding parts made of copper or copper alloy. The conditions of use of these components and post-weld processing vary, so the requirements of the solder joints are not the same. High-frequency components such as waveguides, cavities and other components, generally after welding to be machined or artificial trimming and polishing, and then plating. Such components require welding deformation, processing precision and surface size accuracy
