Subject: [TN] Definition of Sulfur Free


Anyone have a working definition of "sulfur free" as it impacts solderability of silver finishes?

As an old chemist I would expect the definition "sulfur free" could have both a concentration and a time a part can be exposed to that concentration before soldering is impacted.

Any thoughts/assistance is appreciated.
