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.

Subject: [TGA] 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!
