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

I see what you mean. Most "oldskool" lead products most likely will contain "odskool" fluxes as well. For me who smelled rosin since I was little kid it is still OK, but in general modern fluxes not only work better, but also do not smell/evaporate that much.

Good reason to use a modern flux then and proper extraction. But lead-free fluxes must be more aggressive and will be used at higher temperatures. If you use the same flux in lead and lead-free, the leaded solder will inherently be safer as the temperature reached during soldering should be lower.

Although I'm sure that stuff is not too bad: http://tds.henkel.com/tds5/Studio/ShowPDF/243%20NEW-EN?pid=LOCTITE%20C%20511&format=MTR&subformat=MLTC&language=EN&plant=WERCS

Is halide a health concern at this level? Not sure.



--- Quote ---A typical lead-free solder wire generally contains 2 to 3 percent flux by weight, broadly similar to conventional solders. However, the flux content may have to be more aggressive to achieve the same degree of solder wetting, which yields stronger, more potentially harmful chemicals.

Hobby, research and development - leaded solder.
Customer stuff - lead-free, leaded upon request for prototypes.

Provided people do not start licking or eating the boards, they should be fine.

Yes, the EU nannies won't let dealers sell leaded solder to private person any more. I stocked up on a lifetime supply before that happened.
But you can find it on Ali & Evilbay.

I just wonder how many of you still use leaded solder for projects and prototyping compared to ones who are green

No problem ordering from Farnell. Just received 2 rolls last week. But I have to say I use it for prototyping only.
