[TN] Arsenic from XRF Testing
All,
I have a question. We were seeing some solderability issues with some
components that were provided by our customer. These devices were Sn-Pb
over Cu plating per the data sheet. We tested 3 samples and noticed where
all three samples have very high concentration of Arsenic. Some as much
4-5%. What could possibly be the cause for this? I understand Arsenic is
used during plating process but I did not think it was as significant as
4-5%.
