Before welding work
Wet the cleaning sponge with water first, then squeeze out the excess water. Only in this way can the tip of the soldering iron get the best cleaning effect. If you use a non-moist cleaning sponge, it will damage the tip of the soldering iron and cause it to fail to tin.
When performing soldering work, the following welding sequence can protect the tip of the soldering iron and reduce the oxidation rate.
After welding work
First adjust the temperature to about 250°C, then clean the tip of the soldering iron, and then add a new layer of tin for protection. (If you use a non-temperature-controlled soldering iron, cut off the power first, and let the temperature of the soldering iron tip drop slightly before tinning.)
Try to use low temperature soldering
High temperature will accelerate the oxidation of the soldering iron tip and reduce the life of the soldering iron tip. If the temperature of the soldering iron tip exceeds 470°C, it will oxidize twice as fast as 380°C.
When soldering, do not apply too much pressure, otherwise the tip of the soldering iron will be damaged and deformed. As long as the soldering iron tip 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 soldering iron tip tinned
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 has dropped slightly, so that the tin plating layer has a better anti-oxidation effect.
Keep the tip of the soldering iron clean and remove oxides immediately
If there is black oxide on the tip, the tip may not be tinned and must be cleaned immediately. When cleaning, first adjust the temperature of the soldering iron tip to about 250°C, then clean the soldering iron tip with a cleaning sponge, and then tin it. Repeat the action until the oxide is cleaned up.
Use low activity flux
Fluxes with high mobility or strong corrosiveness will accelerate the corrosion of the soldering iron tip when heated, so low corrosive fluxes should be selected.
Put the soldering iron on the soldering iron stand
When the soldering iron is not in use, the soldering iron should be carefully placed on a suitable soldering iron stand to prevent the soldering iron tip from being damaged by collision.
