How to keep the non-stick tin on the tip of an electric soldering iron from oxidizing
Most of the soldering iron tip won't stick to tin when using a lead-free soldering iron tip. In addition to the product's inherent quality issues, this could also be the result of inappropriate temperature selection, improper use, poor cleaning techniques, etc. This could quickly lead to severe oxidation on the tin surface of the soldering iron tip. Let's examine the causes by following the editor:
1. The tin surface of the soldering iron tip is easily severely oxidized at high temperatures.
2. Avoid eating the tin surface before using it.
3. Using subpar or inappropriate cleaning techniques.
4. The interruption of the wire's flux or the use of impure solder.
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" electric soldering iron tip, which occurs when there is no tin on the surface of the electric soldering iron tip and the soldering station is not in use. This causes the electric soldering iron tip to oxidize quickly.
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.
The customary approach:
To reveal the copper that has not yet been oxidized by air, use a knife to scrape off the oxide coating from the soldering iron tip. It can then be used normally after being placed in the rosin box and dipped in tin. This approach does not, however, totally eradicate it. In addition, if it is scraped off for a protracted period of time, the soldering iron's tip will thin down and lose some of its ability to transfer heat, which will cause the temperature to decline and even cause tip damage.
A quick and efficient way to do this is:
Holding the electric soldering iron's wooden handle, submerge the oxidized tip in an alcohol-filled container for one to two minutes. When you withdraw it, the oxide will have been totally and thoroughly eliminated, and the soldering iron tip will appear as good as new. This is so that the copper is decreased when the copper oxide and alcohol are heated, which has no corrosion-causing effects on the tip of the electric soldering iron.
