The history of soldering goes back some 5,000 years, but fundamental soldering has always used Sn-Pb series solder that consists of tin and lead. However, lead pollution ground water 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 "ECO SOLDER."
We are thoroughly prepared to introduce Lead-Free soldering system as we have a comprehensive technology base and have constructed support systems in various phases with ECO Soldering Solution.
