The solution to the soldering iron tip not sticking 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. Contact with organic substances such as plastics, lubricating oil or other compounds. The customary approach:
It is to use a knife to scrape off the oxide layer of the soldering iron tip to expose the copper that has not been oxidized by air. Then, put it in the rosin box and dip it, then dip it in tin, and it can be used normally. However, this method does not remove it thoroughly. At the same time, if it is scraped off for a long time, the tip of the soldering iron will become thinner and affect heat transfer, resulting in a drop in temperature and even damage to the tip of the soldering iron.
A quick and efficient way to do this is:
Holding the wooden handle of the electric soldering iron, immerse the oxidized soldering iron tip in a container filled with alcohol, take it out after 1 to 2 minutes, the oxide will be completely and cleanly removed, and the soldering iron tip will look brand new. This is because after the copper oxide and alcohol are heated, a chemical reaction occurs, and the copper is reduced, which has no corrosion effect on the tip of the electric soldering iron.
