If you can control the variation within the supplier’s specification, that should be fine.

I have not seen an industry standard on what range is accepted, and I am eager to know about it if there is.

关于焊锡成分分析

 

诸位,早上好:

 

向大家咨询一个关于焊锡的金属元素分析的问题。

 

各位是否知道,根据什么标准,对波峰焊的锡池内的焊锡的金属元素都包含什么金属元素?

 

标准是多少?在哪里可以检测到这些金属元素的成分?我公司内用的焊锡Sn/Pb比例为63/37

 

或者,在您所在的公司内关于这项内容是如何控制的呢?

 

 

thanks a lot.

 

Best Regards!
