Solder Wire Sn99.3/Cu0.7 Rosin Core Solder Wire for Electrical Soldering Lead Free Solder Wire Universal Tin Wire Flux

（1）Low residue:

Bright solder joints low ionic residue, clean and beautiful, high insulation resistance, very low corrosion.

（2）Excellent material:

Adopting high quality and high purity tin ingot rawmaterial+ electrolytic lead fused with a special processrefned,conductive and thermal conductivity performance is good.

（3）Wide range of uses:

Suitable for electronic products circuit board welding LED household appliances computer, microelectronic products welding, etc.

（4）Bright and firm solder joints:

Good wettability and expansion ability effcient removal of oxide film, strong ability to remove oxide flm, smooth and bright solder joints.

（5） Sturdy and durable:

Ensure sufficient amount of solder wire per roll. The wire will not tangle and the rosin inside the wire is evenly distributed to ensure good continuity. When using our solder wire, you will find it robust and durable. It has good elongation, melting, electrical and thermal conductivity.

HOW TO USE:

1、When used, in order to obtain a good welding effect, the welded part must be weldable, the surface of the welded metal should be kept clean, the use of appropriate lead-free soldering iron head.

2、After opening the soldering iron switch, wait until the soldering iron temperature rises to the required operating temperature before welding.

3、The operator's head should be 20 CM away from the pad.

4、When the soldering iron is not in use, a layer of tin should be plated on the soldering iron, and then turn off the power switch.
