Do you still use leaded solder? I was today refused to buy it ...

This is like in California you can't buy acrylic cement for hobby/personal use. But if you say that it is for work, then it all of a sudden becomes ok. This transaction is obviously easy when you are in buying person, but I assume suppliers will adapt and have a checkbox of some sort.

Not meaning to trigger flamewars, but it looks like California is a bit like the EU of the USA. :P

Yep. Might not pass customs... although it's still pretty rare.

Mainly for reliability reasons indeed. The leaded parts are never in contact with the body, and the implants themselves are not supposed to open up or leak. (If that ever happens, the main concern for the patient is rarely going to be the lead.)
Tin whiskers anyone?

I've been using lead-free solder for personal projects for, oh, 20 years now, with no complaints or issues. Day jobs since forever have been lead free, too, for obvious reasons.
This is everything from soldering boards with SMT devices to building audio cables.
Seriously, i think those of you railing against lead-free solder are just complaining about "The Gubbmint won't let me do something I want to do waaaah waaaahh complain complain bitch moan."

Yes in china you can blow asbestos dust with a Freon ("Good" old R-12 Dichlorodifluoromethane) they are on the other extreme

This looks like an interesting alternative to try
Just read quality vary significantly between manufacturers :-//

Has anyone in Europe tried ordering leaded solder from Digi-Key or Mouser? They do not appear to restrict sales of leaded solder to individuals, but I have yet to try. (I got several rolls of leaded Tamura-Elsold and Stannol solder from work, so I’m set for quite some time now…)
