While removing the oxide film, the surfactant in the
solid solder wire flux also starts to work, which can significantly reduce the surface tension of the liquid solder on the surface of the material to be soldered, and enhance the fluidity and spreading ability of the liquid solder. And ensure that the tin solder can penetrate into every tiny brazing gap. The most suitable temperature for soldering work is the melting point of the solder used +50 degrees. The set temperature of the soldering iron tip, due to the size of the soldering part, the power and performance of the electric soldering iron, the type of solder and the wire type, should be increased by 100 degrees on the basis of the above temperature.
Flux is added to the solid solder wire solder, which is composed of rosin and a small amount of activator. The temperature setting during soldering work is very important. In standard soldering operations with solid solder wire, the wire solder used is called rosin-cored solder wire or solder wire. Use the authentic soldering iron head matched with the manufacturer (such as Baiguang Tools): fake soldering iron head, the hole diameter (into the heating core) is large or small, and the thickness of the sleeve is also different. The reason for the failure of the soldering iron.
The temperature management of the soldering iron tip during the solid solder wire soldering process is very important: it is very important to choose the most suitable temperature setting of the soldering iron tip according to the solder wire used for an electric soldering iron with temperature regulation. Before working, it is important to measure the temperature of the soldering iron tip with a soldering iron tip thermometer. In the tin furnace welding process of solid tin wire, when the body to be welded leaves the surface of the tin liquid, the excess tin solder will flow down the pins due to the wetting effect of the flux, thus avoiding sharpening, continuous welding, etc. unpleasant sight.
