We did some experiments with our paste and when correctly stored we have
extended the life by 3 months without any discernible problems.

You would need to do your own experiments with your paste and the
experiment should take into account the target usage.

The above is another way of saying 'it depends' but that is someone
else's catch phrase.

Hi,

What are the consequences of using expired solder paste?
How long after the expired date is "acceptable"?

Thank you.
