You need lead free / RoHS certified components to use with lead free
solder. You can not mix leaded with unleaded solder. So you need
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
will take an other 10 years until we hit this problem in this mailing
list. ;-)
