[Welcome]

Your solder expired a long, long time ago. I advice everyone to stay away.

Solder expires? I did not know...Do I need to start removing / re-soldering all solder joints I have ever made?

I may be interested in a pair of 627 and pair of 797 with the adapters...let me know if still available...

There is no expiration date on it, even the manufacturer does not reveal such information. Do you know how much it costs for a roll of WE solder dated from 1940's?

From now, I will include 2 TDK 0.22uf C0G/NP0 capacitors for every OP amp purchase at free of charge. These are $1.75 ea at Mouser or DigiKey!

Sorry, the deal is off now. I will keep those caps for myself, but they are still on sale.

Yes, solder does expire apparently. I picked up 5 sealed 1 pound spools of solder at a flea market for 5 bucks. It's marked with tags, Date received 10-12, Date expires 10-16. It's all leaded flux core in either 0.020 or 0.032 diameter. Guy said they were an ISO 9000 company and it was to close to the date so they tossed it. I never heard of such a thing before. And to think I've been using solder from a stash I picked up almost 20 years ago. LOL

I asked the same question to Almit. They said there is 2yr warranty for their product. If stored properly (controlled humidity, temp), no need to worry about it.
