How to prevent soldering iron head oxidising without tin staining
Most of the soldering iron tips will not be tin-stained when lead-free soldering. In addition to the quality of the product itself, there may be due to the choice of temperature is too high, easy to make the soldering iron head tin surface intense oxidation, the use of incorrect or defective cleaning methods and other reasons. Follow the editor to analyse the reasons:
1, select the temperature is too high, easy to make the soldering iron head tin surface intense oxidation.
2, not before the use of the tin surface to eat tin.
3, the use of incorrect or defective cleaning methods.
4, the use of impure solder or flux interruption in the wire.
5, when the working temperature exceeds 350 ℃, and stop soldering for more than 1 hour, lead-free soldering iron tip on the amount of tin is too small.
6, "dry burning" soldering iron head, such as: soldering station open without using, and the surface of the soldering iron head without tin, will cause rapid oxidation of the soldering iron head.
7, the use of flux is highly corrosive, thus causing the rapid oxidation of the soldering iron head.
8, the use of neutral activity of the flux, not often clean up the oxides on the soldering iron head.
9,Contact with organic materials such as plastics, lubricants or other compounds.
The usual treatment:
Use a knife to scrape off the oxidised layer of the soldering iron head, exposing the copper that has not been oxidised by the air. Then, put it into the rosin box and dip it, and then dip it in tin, it can be used normally. But with this method of removal is not complete, at the same time, long-term scraping down, the soldering iron tip will become thin and affect the heat transfer, resulting in a drop in temperature, or even damage to the soldering iron tip.
The fast and efficient way to deal with it is:
Hold the soldering iron wooden handle, the oxidised soldering iron tip is immersed into the container with alcohol, after 1 ~ 2 minutes to take out, the oxides are completely and cleanly removed, the soldering iron tip is brand new. This is because the copper oxide and alcohol heating, produced a chemical reaction, and restore the copper, no corrosive effect on the head of the soldering iron.
