Solder wire is one of the indispensable electronic accessories for welding and repair welding in the electronics industry. According to the production process, it can be divided into two types, one is solid core, the other is hollow core and rosin. At present, the tin wire with hollow core and rosin It can be used for direct welding during welding, which is convenient and widely used, and the efficiency is much higher. Recently, some people have asked what is active solder wire and what are its advantages?
Active solder wire actually refers to the solder wire with activator added, which is more conducive to welding; the active agent in the active solder wire is to improve the auxiliary heat conduction of the solder wire during the welding process, remove oxidation, and reduce the surface tension of the material to be welded. Remove oil stains on the surface of the material to be welded and increase the welding area.
The characteristic of active solder wire is tin alloy wire with a certain length and diameter, which can be used in conjunction with electric soldering iron in the welding of electronic components. In the production process of solder wire, especially lead-containing ones, it is necessary to choose a reasonable formula, so that the solder wire can improve the expansion rate while the performance is qualified, the solder joints are full and bright, the flux residue is non-corrosive, and the insulation resistance is high.
Active solder wire will be better tinned and more active in welding. For the welding requirements of some special processes, active solder wire can be selected. At present, the solder wire produced has activator ingredients added to improve soldering performance. Excellent welding fluidity and welding quality.
