You need lead free / RoHS certified components to use
with lead free
solder. You can not mix leaded with unleaded solder. So you need
As I understand it (and partical experience partially verifies this), the
problem is contamination of lead-free solder with lead. Not the reverse.
In other words, you can't use old leaded components with lead free solder,
but there's no problem in soldering lead-free components with lead/tin
solder I've done that many times and had no problems.
different tips for your soldering iron to prevent
contamination.
Unleaded solder needs higher temeratures also. I.e. if you repair
older, leaded electronics you must use leaded solder. So most likely it
Sure. Which I do anyway.
The point is for things I build myself for myself. I am currently
sticking to leaded solder (for many reasons), my comment was that as the
amount of lead in the fumes is miniaml -- they're mostly flux -- and as
the lead-free flux is more toxic, I may acutally be safer sticking to the
lead solder.
will take an other 10 years until we hit this problem
