Why is the tip of the soldering iron prone to oxidation and blackening?
1. The temperature of the electric soldering iron is too high during soldering, which may easily cause rapid oxidation of the soldering iron tip
2. After soldering, the tip of the soldering iron was not tinned in time
3. The quality factor of the soldering iron tip itself
4. The flux used is highly corrosive, which causes rapid oxidation of the soldering iron tip;
5. If the tip of the soldering iron is exposed to high temperature for a long time, it is easy to produce intermetallic compounds of tin and iron, and the tip of the soldering iron oxidizes rapidly. If the soldering iron is not used for more than ten minutes, please turn off the power in time
6. If the soldering tip is covered with carbonized flux, the soldering tip will not be able to melt the tin and send enough heat to the solder joint, because the soldering tip must transmit heat through the molten tin as a medium, and the iron-plated layer of the soldering tip It will be exposed to oxidation due to insufficient molten tin.
