What is lead-free solder?

Lead-free solder is solder which does not contain lead. As lead is harmful to the environment, lead-free solder is made from mixture of tin, silver and copper. The conventional solder is a mixture of lead and tin. Since 1999, EIZO has used lead-free solder on all the printed circuit boards in our products, and is just one example of our efforts to develop and manufacture environmentally sound technology.
