Soldering iron head does not touch the tin how to do and how to deal with it
Soldering iron tip not tin how to do and processing methods
1, choose the temperature is too high, easy to make the soldering iron head tin surface strong oxidation.
2、 The tin surface is not eaten through before use.
3、 The use of incorrect or defective cleaning methods.
4, the use of impure solder or flux interrupted in the wire.
5、 When the working temperature exceeds 350 ℃ and stop soldering for more than 1 hour, the amount of tin on the tip of the lead-free soldering iron is too small.
6, "dry burning" soldering iron head, such as: the soldering station is open without using, and the surface of the iron head tin-free, will cause rapid oxidation of the iron head.
7, the use of flux has a strong corrosive, thus causing the rapid oxidation of the soldering iron head.
8, the use of neutral activity of the flux, can not often clean up the oxides on the soldering iron head
9、 Contact with organic materials such as plastic, lubricating oil or other compounds. The usual treatment method:
Use a knife to scrape off the oxidized layer on the soldering iron tip to expose the copper that has not been oxidized by air. Then, put it into the rosin box to soak, and then immersed in tin, can be used normally. However, with this method of removal is not complete, at the same time, long-term scraping down, the soldering iron head will become thin and affect the heat transfer, resulting in a drop in temperature, or even damage to the soldering iron head.
The fast and efficient way to deal with it is:
Hold the iron wooden handle, the oxidized soldering iron tip immersed in a container of alcohol, after 1 ~ 2 minutes to remove, oxides on a thorough, clean removed, soldering iron tip a new look. 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.
