About lead-free technology:
1. The European Union passed a bill in 1998, which has clarified that from January 1, 2004, lead-containing solders cannot be used in any electronic products.
2. Beginning in 1997, the National Manufacturing Science Center (NCMS) lead-free soldering project jointly conducted by 11 US industrial groups and national laboratories has completed a four-year plan to identify and evaluate alternatives to tin-lead solder. The purpose of the project is to determine whether there are safe, reliable, non-toxic and economical alternatives to lead-containing solder in the manufacture of electronic products.
3. Lead-free targets set by Japanese companies and products for mass production.
