News Events European WEEE directives mandate a phase out of lead in electronic soldering by July 2006 and Japans efforts to do the same are sooner. In many European countries legislative measures have been passed to restrict its usage and lead-free standards are expected to become global. Lead-free soldering is rapidly taking on momentum around the world. Realizing the high toxicity level and harmful after effects of lead electronics manufacturers are shifting to lead-free products. Currently lead-free assembly has a low penetration rate and accounts for less than 5% of all electronic systems. In the lead-free implementation process, many companies are assembling in mixed production environments. Phasing out the lead containing materials as soon as feasible with lead-free. In mixed production environments, the possibilities of cross contamination are more likely than ever. Lead-free and lead containing solder pastes are grey in color and because of their very similar visual appearance, are likely to cross contaminate in a mixed production environment. Qualitek has developed LF GREEN® to avoid cross contamination. LF GREEN® is a patent pending lead free solder paste that is green in color and remains green during the entire soldering process until reflowed. Once reflowed, clear residues remain with normal metallic joint appearance. Under black light LF GREEN® boards will fluoresce once again easily identifying the lead free boards. LF GREEN® is available in the most common lead free alloy compositions of Sn/Ag/Cu and Sn/Ag and costs are the same as typical lead free solders because costs are based on the metals and not the green color of the paste. Formulations are available in No-Clean, Water-Soluble and RMA flux types. Available in type 3, 4 and 5 meshes. Packaged in DEK Proflow Cassettes, Jars and Cartridges.
