Matsushita Electric Ind. Co. Ltd has completed a switchover to the use of lead-free solder for PCBs used in Panasonic and National brand products. Aiming to promote its environmental activities on a global basis, the use of lead-free solder conforms to the European Union's regulation on restrictive use of toxic substances.

Matsushita first introduced mass-produced lead-free solder used for PCBs on its portable MD player back in 1998. Since then, the company has been introducing the use of lead-free solder in other products such as headphone stereos, and VCRs. By the end of March 2003, PCBs using lead-free solder was employed in about 12,000 models manufactured in 22 domestic facilities and 79 overseas facilities of the Matsushita Group. Of the 2,400 tons of solder used in 2002, about 856 tons (36 percent) used lead-free solder.

With the switchover to lead-free solder complete, Matsushita expects more than 80 percent of the solder produced to be lead-free. Since the company first introduced lead-free solder, Matsushita has produced a total of about 70 million units that contain PCBs with lead-free solder.

In the years ahead, Matsushita plans to promote the introduction of lead-free solder with the cooperation of suppliers and customers. In addition, efforts are presently underway to eliminate lead from the metal plating on component electrodes.
