Lead Free Solder Defined:
On July 1, 2006 the European Union Waste Electrical and Electronic Equipment Directive (WEEE) and Restriction of Hazardous Substances Directive (RoHS) came into effect prohibiting the intentional addition of lead to most consumer electronics produced in the EU. California recently adopted a RoHS law and China has a version as well. Manufacturers in the U.S. may receive tax benefits by reducing the use of lead-based solder.

 

Lead-free solders in commercial use may contain tin, copper, silver, bismuth, indium, zinc, antimony, and traces of other metals, including lead itself.

The maximum permitted concentrations are 0.1% or 1000 ppm by weight of homogeneous material.
