When soldering solid core solder wire, it is necessary to add flux, and the selected flux should be composed of rosin and a small amount of active agent. Temperature control is the most important thing when solid welding wire is used for welding. During the welding process, the melting point of the welding should be kept at 50 degrees Celsius. When soldering solid solder wire, the temperature of the soldering iron tip should be accurately controlled. According to the size of the soldered piece, as well as the performance and power of the soldering iron, different types of solder and the linearity of the solder wire can be selected. Should exceed 100 degrees Celsius.

When the solid solder wire is used for standard soldering, the wire solder used is called rosin core solder or solder wire. When soldering, it needs to be soldered with the authentic soldering iron tip provided by the manufacturer. Usually there are counterfeit soldering iron tips on the market. The holes of the soldering iron tips are different in size, and the thickness of the sleeve used is also different. Therefore, we should try to choose the appropriate soldering iron when soldering with solid solder wire. Soldering iron head to ensure the normal performance of welding quality. When the oxide film of the solid solder wire is removed, the surface activity in the flux also starts to work, which can fully display the surface tension of the soldered surface, ensure the fluidity and stretchability of the liquid solder, and also ensure the solder material. Penetration of every brazing gap is guaranteed.

When using an electric soldering iron to solder solid solder wire, the most important thing is to control the temperature. If the soldering iron has a temperature setting function, then we can choose a suitable temperature to set according to the solid solder wire used. Before soldering, it is very important to measure the temperature of the soldering iron with a soldering iron thermometer. When the solid solder wire is soldered in the tin furnace, when the solder body leaves the surface of the tin liquid, the wetting effect of the flux can help the excess solder to flow down the pins, which avoids continuous soldering and pulling. sharp phenomenon.
