The solder wire used in manual electronic raw device welding is composed of tin alloy and additives. In electronic welding, the solder wire is matched with the soldering iron, and the high-quality soldering iron provides stable and continuous condensation heat. The solder wire is added to the appearance and gap of the electronic raw device as the filler metal. The composition of solder wire is closely related to the quality of solder wire, which will affect the chemical and mechanical properties and physical properties of solder wire. Solder wire without additives can not stop the welding of electronic components, this is because it does not have wettability, expansion. And stop welding will produce spatter, solder joint composition is not good, long time to develop the performance of additives affect the performance of solder wire welding.

The following is the use of different types of solder wire

1. Loose flavor solder wire: suitable for electronic repair welding of electronic and related components, welding residue impedance is high, no leakage, can pass high voltage test, is the most commonly used tin wire in the electronics industry.

2. Wash free type solder wire: suitable for PCB board repair welding request less welding residue, high insulation impedance, clean surface, etc.

3. Nickel plating type solder wire: suitable for nickel material, surface nickel plating components, wire, terminal, socket, lamp No. 1 hard data welding.

4. Welding aluminum solder wire: suitable for aluminum welding, this kind of flux is non pine flavor, solid welding, the effect is very good, welding residue can be cleaned with water.

5. Stainless steel solder wire: suitable for welding of stainless steel, this kind of flux is non-pine flavor, welding firm, the effect is very good, welding residue can be cleaned with water.

6. Solid core type solder wire: no flux, suitable for fuse, metal pipe fittings and other special uses.

7. Mobile phone drag welding special soldering wire: suitable for mobile phone accessories, IC, wire, connecting line and other multi-angle welding, welding effect is very good, small spacing drag welding once in place.
