Eco Products: Senju Metal Lead-Free Solder

The "RoHS Directive", a set of regulations issued in the EU regarding chemical substances used in electrical products and precision machinery, took effect in July 2006.

Amid the trend to switch to environmentally-friendly products, our company is also providing a lineup of ECO products.
We would be happy if they would be of any contribution to the sales expansion of your company.

Senju Metal Industry Co., Ltd. Lead-Free Solder

Lead-Free Solder SPARKLE ESC F3 M705


Lead-Free Solder M705 While solder has a 5,000-year history of use, its fundamental role has been played by Sn-Pb solders, consisting of tin and lead. However, in recent years, contamination of groundwater by lead has been a problem, raising calls for a total abolition of lead, recognized as an environmentally-hazardous substance.
Recognizing environmental protection in the 21st century as our social responsibility, we at Senju Metal Industry have conducted extensive research and developed a lead-free "ECO SOLDER".

At our company, we hold "M705" as standard stock

ESC M705 F3 solves problems found with conventional lead-free solders, such as wettability and heat resistance issues associated with higher melting points. It is a next-generation, environmentally-benign solder that provides for great workability.
