The soldering iron tip coating is usually iron-nickel-chromium-tin. The iron coating is the key to the quality of the soldering iron. At high temperatures, iron and tin will form an alloy, which will dissolve in the liquid solder, resulting in the surface coating of the soldering iron. The loss of iron is the phenomenon that the tip of the iron is perforated; the speed at which lead suppresses the effect of the alloy cannot be completely eliminated. In addition, the higher the composition of tin in the lead-free solder, the more severe the corrosion; the higher the temperature, the faster the corrosion This is why lead-free soldering tips are faster than leaded soldering?
If you have used a soldering iron tip, be sure to pay attention to the following points:
1. Clean the tip with a cleaning sponge;
2, turn off the power supply and other soldering iron head cooling;
3. The tip should be covered with solder;
4. Put the automatic soldering iron soldering iron pen into the soldering iron bracket.
