1. What is the definition of Pb-free?
Content less than 1000 ppm Pb by weight (E3).

2. What is the definition of 'Green'?
Product complies to RoHS (Restriction of use of Hazardous Substances) legislation.

3. Why lead-free?
Environmental improvement (reduction or elimination of the potential hazardous effects from lead poisoning).

4. What is driving the move toward Pb-free products and processes in the electronics industry?
Pb has long been recognized as a harmful environmental pollutant. The use of Pb in electronic products is an increasingly visible environmental and political concern. OEM initiatives and legislation are being implemented globally to drive the removal of Pb and other harmful materials from electronic products.

5. What is RoHS and WEEE?
RoHS and WEEE are European Union (EU) Directives for waste electrical and electronic equipment (WEEE) and for restriction of the use of certain hazardous substances in electrical and electronic equipment (RoHS). Among other things, these directives restrict the use of certain hazardous substances in electrical and electronic equipment shipped in to the EU as of July 1, 2006. The substances identified by the WEEE Directive as hazardous are:
• Cadmium
• Mercury
• Hexavalent Chromium
• Polybrominated biphenyls (PBB)
• Polybrominated diphenyl ethers (PBDE)
• Lead (Pb)
The restrictions do not call for the total elimination of these substances but set an upper limit based upon weight. Pb content in lead plating or solder balls must be less than 0.1% by weight of solder.
