The use of lead-free solder wire editor
Lead-free tin line components
Melting point temperature
The basic characteristics of
Sn99.3Cu0.7
Two hundred and twenty-seven
Low cost, is currently the most commonly used and most economical solder wire, general requirements for welding
Sn96.5Ag3.0Cu0.5
Two hundred and twenty-two
With high silver content, the cost is high, but the solder is the most bright, the best welding performance.
Sn99Ag0.3Cu0.7
Two hundred and seventeen
With a small amount of silver, bright spot, the performance is excellent, for the higher requirements of welding.
Edit characteristic of lead-free tin wire
- good solderability, good wetting properties
Line in Rosin evenly distributed, good continuity
And no bad smell, smoke less, do not contain toxic volatile gases
- wire winding, neat uniform, bright surface

Overall, through the SGS testing, do not pollute the environment
