The history of soldering goes back some 5,000 years ago, but fundamental soldering has always been the Sn-Pb series solder that consists of tin and lead. However, lead pollution in groundwater has been recognized as an environmental problem and complete elimination of the use of lead is called for.
Realizing that protection of our environment is our task in the 21st century, SMIC has earnestly extended our research in this area and developed Lead-Free solder "ECO SOLDER." Please contact for any problem that relates to Lead-Free soldering. We are thoroughly prepared to introduce a Lead-Free soldering system as we have a comprehensive technology base and have constructed support systems in various phases.
