Hi Rich - we use solder/dross recovery equipment (we call them solder 
"boots" because of their shape) in three of our facilities and we put the 
recovered solder bars back into the wave solder machine. I have conducted 
a couple of metallurgical composition tests on the recovered bars to see 
if they contained an excess of any elements and did not find anything that 
I considered an issue. We have about 5-6 years of history with no issues 
to date. 

Dave

[TN] Local Solder Dross Recovery & solder joint reliability






I was surprised to have searched the TechNet archives and not found much
recent discussion on this topic. 

Can I get any of your thoughts on the reliability of solder joints that
includes solder that was locally recovered from dross taken from the
same manufacturing site?
