TechNetters,
Why would ANY solder (with the possible exception of solder preforms that were flux encrusted) have an expiration date?  I seem to recall there being a paper where someone did rework with solder wire with flux in it that was
20 years old and there was no problem.

Regards,
Bev

Fellow TechNetters:

   Does Solid Bar LF Solder Vaculoy have an associated EXPIRATION DATE?
