While solder has been used for 5,000 years, Sn-Pb solders (tin and lead) have been predominant. However, due to lead contamination in groundwater, there’s a push to eliminate lead, an environmentally hazardous substance.
Our company offers “M705” as standard stock. ESC M705 F3 addresses issues with conventional lead-free solders, such as wettability and heat resistance. It is a next-generation, eco-friendly solder that ensures excellent workability.
We have SPARKLE ESC F3 M705 in various sizes:
Senju Metal Industry’s lead-free “ECO SOLDER” is more reliable than traditional Sn-Pb solders. For other transformer products, please contact us.
