But I can definitely understand the military / medicals industries use of extreme caution with tin products for sure. I also respect the wealth of knowledge I find from you around here Steve... do you have common examples of failures or increased QC problems you've come across after the switch to lead-free?
There were a few years between lead and unleaded but it was a bit like riding a bike .
Lead free does not flow as easily and will readily form a spike if you hang around for a moment too long .
Once you come to terms with its "personality" its fine .
Lead is nasty stuff, if you work with it every day it will find a way in .
If you only make a couple of cables there is nothing to worry about but regulators must consider industrial exposure .
I used silver solder(lead free) on a cable I made, using same cheap 25w(?) iron I use for everything else(cleaned the tip first.) My impression was that the lead free being problematic is somewhat exaggeration. I did get a dry joint that looked ok on a socket mod I did but a simple fluxless reheat fixed it.
