Carl,
I'm in a meeting, so can't look at any tables of x-ray energies.  Any chance that the equipment is picking the wrong element? Is there a secondary x-ray peak you can use to check?  I hope that you take this a constructive suggestion. It is not meant any other way.

Subject
[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%.
