Selection and use of soldering iron

The soldering iron is an important tool for soldering electronic components. When soldering wire is used together with the soldering iron, the best effect can be achieved. Therefore, the soldering effect of the soldering wire is good or bad. The soldering of the soldering wire is mainly by the soldering iron. The temperature is allowed to melt for the purpose of final soldering, and the choice of soldering iron is important. Today, the technical staff of Shenzhen Xinghongtai manufacturers introduce the selection and use of electric soldering iron:

First, the choice of electric iron:

Choosing the right soldering iron will help to greatly improve the efficiency of our lead-free soldering. However, in general, the choice should be based on the actual situation of the object being soldered. Generally, the heating type, power level, and tip are generally considered. Shape and so on.

Second, the use of electric iron

1. The soldering iron should be tinned before use. The specific method is: heat the soldering iron. When the solder can be melted, apply flux, and then evenly spread the soldering iron on the soldering iron to make the soldering iron evenly eat. A layer of tin.

2. Soldering method: Dip a proper amount of solder with a soldering iron tip, contact the solder joint, and after the solder on the solder joint is completely melted and immersed in the component lead, the soldering iron tip is gently lifted up along the lead of the component. point.

3, the welding time should not be too long, otherwise it is easy to burn the components, if necessary, you can use the tweezers to clamp the pins to help dissipate heat.

4. After the welding is completed, the residual flux on the circuit board should be cleaned with alcohol to prevent the flux after the carbonization from affecting the normal operation of the circuit.

The selection and use of the soldering iron is introduced here. The soldering wire must be adjusted to the temperature of the soldering iron before soldering. Before soldering the soldering wire, the temperature of the soldering iron tip should be tested with a thermometer before soldering.
