Oh, just found some more interesting stuff in that old box... some solder paste ! 5 NOS 35grams syringes, Mfg date on the stickers on them range from mid '89 to late 1990, 32 years old !

Never used solder paste, but sure enough not good anymore, so had some fun and tried it on a small scrap board !

It does not look pretty
It also smells so bad that in comparison acetone smells like rose !
I hope I did not lose too much life expectancy there... a fume extraction system is most definitely on the list of things to get in the lab !
I just can't stand breathing flux fumes anymore, I am getting old I guess... but even for 10 seconds, still too much for me.. this stuff is just horrible.
