Greetings,

I've never done hot-air soldering but am helping set up a lab. I
understand we need solder paste and its shelf life is short. But I just
found some solder paste that has been out of refrigeration more than 7
years, and it still looks like paste. What quality has it lost?
Stickiness?

How important are reliability and traceability (ISO 9000) in your lab?

So can you tell me what happens to solder paste when it gets old?

No, that would be your problem.
