9 Reasons Why Your Soldering Iron Doesn't Stick to Tin
1. If the temperature is too high, it is easy to cause severe oxidation on the tin surface of the soldering iron tip.
2. Do not eat tinned surface before use.
3. Using incorrect or defective cleaning methods.
4. The use of impure solder or flux interruption in the wire.
5. When the working temperature exceeds 350°C and the soldering is stopped for more than 1 hour, the amount of tin on the lead-free soldering iron tip is too small.
6. "Dry burning" electric soldering iron tip, such as: the soldering station is not in use, and there is no tin on the surface of the electric soldering iron tip, which will cause rapid oxidation of the electric soldering iron tip.
7. The flux used is highly corrosive, which causes rapid oxidation of the soldering iron tip.
8. Use neutral active flux, and do not often clean the oxides on the tip of the soldering iron.
9. Exposure to organic matter such as plastics, lubricating oil or other compounds. customary approach.
