Well we are certainly not doing it to look nice. In fact, as I stated earlier, this is someting a supplier of a supplier does. I'm a chemist, not a component designer, so I don't know why the supplier decided to solder portions of their device with lead. Bev

Greater than 85% Pb (which includes 100% Pb) is exempt if there is a
technical reason for using it, i.e. hierarchical soldering, it is not
exempt if there is no technical reason. As in all these things, that is
my understanding of the rules, others may disagree. So you cannot use it
because it looks nice etc........etc.....!

Thanks, Dave, other than a question from someone else, you are the only
other one to respond. However, my original question still stands: can
100% lead be considered a high lead solder to claim the exemption?
Obviously if it is not being used as a solder, I can see the answer
being no, but in the case I have stated...

Bev, I have no idea what you are working on.
Those guys/gals at RIM are tricky people.
YET soldering isn't a key word to any EU Directive.
The application, or product, and customer is important.
If it falls under an EU directive, Lead (Pb) is a restricted material
with as you noted certain exemptions and yahdah, yahdah.
Yours in Engineering, Dave
