Most soldering iron tips do not come into contact with tin when using lead-free solder. Choosing a high temperature, which is likely to induce a violent oxidation of the tin surface of the soldering iron tip, and using ineffective or improper cleaning techniques may also contribute to product quality issues. Let's examine the causes by following the editor:
1. The tin surface of the soldering iron tip is susceptible to severe oxidation at high temperatures.
2. Avoid eating tin that has been dipped before use.
3. Employ improper or substandard cleaning techniques.
4. Interrupting the use of impure solder or flux in the wire.
5. The amount of tin on the lead-free soldering iron tip is insufficient when the operating temperature surpasses 350°C and soldering is halted for more than an hour.
6. "Dry-burning" the soldering iron tip, which occurs when there is no activity at the soldering station and no tin is present on the soldering iron tip's surface. This causes the soldering iron tip to oxidize quickly.
7. Because of the flux's high corrosion potential, the soldering iron tip quickly oxidizes.
8. Use a neutral active flux, and avoid often wiping off the oxide from the soldering iron's tip.
9. Coming into contact with organic materials like plastics, lubricants, or other chemicals
