Hi
We have recently noticed that our lead free solder wire is being supplied with expiry dates (typically 2-3 years after manufacture). I have seen "date of manufacture" information on wire before but I was not aware that a cored solder wire could expire.
I would be interested to hear if you also have expiry dates on the solder wire you use or if it is only this manufacturer?
Also has anyone used wire that has exceeded its expiry date and has any degradation in soldering performance been observed as a result?
Many thanks
