Premium Solder Ver3.1

High quality solder based on high purity tin
This is a high-performance solder that uses a special alloy mainly consisting of tin, silver, and copper. Uses non-halogen flux that does not cause corrosion, reducing resistance by 30% compared to conventional lead solder. Furthermore, we have eliminated impurities that disrupt sound quality.

For high-performance audio equipment and professional instruments and equipment.
Adopts third-generation materials to increase the sense of force, clarity, and amount of information. Improved flux provides even greater workability. Ver.3.1 is a model exclusively for advanced users that has refined the sound quality to the utmost.
