Description
Low temperature lead free Sn-Bi alloy solder is with solid core. We have been engaged in research and develop of soldering techniques and solder production equipments. Up to now, a unique manufacturing technique has come into being and is popularly accepted by customers.
Features
1. Sn-Bi alloy solder has low melting point.
2. It is necessary for this solid core solder wire to coat flux when soldering.
3. Tin bismuth solder has characteristics of uniform texture, good continuity, bright color and luster, etc.
4. Our products meet ROHS and REACH standards.

Suggestions
To realize better soldering performance during low temp soldering, the temperature range of soldering tip should be kept from190℃to220 ℃. In addition, the angle formed by soldering tip and the working surface should range from 30°to 45°. To make it easy to deliver solder, the soldering tip should be connected with both the lead wire in electronic elements and the surface of PCB bonding pad.
