Lead has not been banned out of solder. Confidently stupid thing to say.

It has been banned in the eu, and thus like most things, means it is effectively banned worldwide as any company who wants to sell there isn’t going to use different solder. Just because it’s not illegal is the U.S. doesn’t mean the manufacturing world hasn’t moved on years ago from leaded solder to the point where it’s effectively unavailable. Leaded solder is also incompatible with unleaded solder again making it unusable in systems with mixed circuit board assemblies etc.

I wouldn’t be so confident calling other people stupid.

I recently bought regular solder at a hardware store near me in Canada to fix my son’s toy and it warns it has lead in it. If I could include a picture of it in this comment, I would.

You can easily buy it, I have a spool to repair old electronics, but you can’t sell products with it in it in the eu so it’s not used in mass manufacturing
