A number of people have commented on the active component issues with
lead-free but the original mail did relate to plastics for other mechanical
parts. Don't forget all these parts and others lime:

IDC cables
Wire insulation
Coating and potting on components
Transformer and Inductor coating and impregnations materials
Loose cable insulation
LCD displays

Hi

CA-JoeF (of Flex Circuit/Tesera fame) certainly did well with this
addition to this note tread.

Beyond Joe's great note, I hope I was exploring your own Product
Reliability and Field Needs and your Leadership leading manufacturers
and component suppliers meeting your needs; as well as, their process
which is secondary to your product needs.

I like Joe's note.
