The cleaning sponge must be wetted with water before squeezing out excess water. Only in this way can the soldering iron head get the best cleaning effect. If you use a non-wet cleaning sponge, the tip of the soldering iron will be damaged and the tin will not be applied.

     When performing soldering work, the following soldering sequence can protect the soldering iron tip and reduce the oxidation rate.

■ After welding

    First adjust the temperature to about 250 ° C, then clean the tip of the soldering iron, and then add a layer of new tin for protection. (If you use a non-temperature-controlled soldering iron, turn off the power first and let the temperature of the soldering iron tip slightly lower before you tin.)

■  Try to use low temperature welding

    High temperature will accelerate the oxidation of the iron tip and reduce the life of the iron tip. If the temperature of the soldering iron tip exceeds 470 ° C, its oxidation rate is twice that of 380 ° C.

■ Do not apply excessive pressure

    When soldering, do not apply excessive pressure, otherwise the tip of the soldering iron will be damaged and deformed. As long as the tip of the soldering iron can fully contact the solder joint, heat can be transferred. In addition, choosing the right soldering iron tip can also help heat transfer.

■ Always keep the tip of the soldering iron

    This can reduce the chance of oxidation of the soldering iron tip and make the soldering iron tip more durable. After use, new solder should be added after the temperature of the soldering iron tip is slightly lowered, so that the tin plating layer has better anti-oxidation effect.

■  Keep the tip of the soldering iron clean and remove oxides immediately

    If there is black oxide on the soldering iron tip, the soldering iron tip may not be covered with tin, and it must be cleaned immediately. When cleaning, first adjust the temperature of the soldering iron tip to about 250 ° C, then use a cleaning sponge to clean the soldering iron tip, and then apply tin. Repeat the action continuously until the oxides are cleaned up.

■ Use low flux

    Highly active or highly corrosive flux will accelerate the corrosion of the iron tip when heated, so low corrosive flux should be used.

■ Put the electric iron on the iron stand

    When you do not need to use an electric soldering iron, you should carefully place the electric soldering iron on a suitable soldering iron rack to prevent the soldering iron head from being damaged by collision.

■ Choose the right soldering iron tip

    It is very important to choose the correct size and shape of the soldering iron tip. Choosing the right soldering iron tip can make the work more efficient and increase the durability of the soldering iron tip. Choosing the wrong soldering iron tip will affect the soldering iron's inefficiency and the soldering quality will be reduced.
