Lead tin wire and lead-free solder wire which is better?

From the welding point of view, of course, there is good lead welding, and the weld quality is also good. Lead-free has a high melting point and is relatively unleaded for soldering.

From the perspective of environmental protection, lead-free is good. Lead-free is mainly an environmental protection requirement. Now, some products, especially export products, require the use of lead-free.

The following are the characteristics of lead-free and lead-free

Lead-tin wire features:
1. Bright solder joints, good wettability, easy on tin. .
2. Composite flux, welding does not splatter,
3. The flux is evenly distributed and no flux is broken in the wire core.
4. Neat winding, no knotting, easy welding operation, high work efficiency.

Lead-free solder wire features:
1. Wet, conductive, and good thermal conductivity.
2. Moderate flux, welding does not splash.
3. The flux is evenly distributed and no flux is broken in the wire core.
4. Neat winding, no knotting, easy welding operation, high work efficiency.
5. To achieve environmental protection lead-free solder wire is RoHS compliant, SGS certified
