摘要: |
通过对比分析的方法,分别研究镀金航插焊杯手工及激光一次搪锡除金、两次搪锡除金的结果, 测量合金层厚度,观察合金层形貌。发现无论是手工方法还是使用激光,一次搪锡除金不能使金含量低于3%,两次搪锡除金后金含量均低于3%,但激光搪锡得到的金相组织更为细腻均匀,合金层厚度更薄且效率更高。最终得出激光搪锡除金效果优于手工操作的结论,对航插焊杯除金工艺方法有更先进的指导意义。 |

Abstract: |
By comparative analysis, study the results of manual one tinning degolding, laser one tinning degolding and laser two tinning degolding for aviation electronic connector solder cup, measure alloy layer thickness and observe alloy layer morphology. It was found that whether manual method or using the laser, the gold content of one tinning degolding was no less than 3%, and gold content after two tinning degolding was lower than 3%, but laser lining tin got more exquisite and uniform microstructure, with thinner alloy layer thickness and higher efficiency. Finally, the effect of laser tinning is better than manual operation, and it has a more advanced guiding significance for degolding process of welding cup. |
