Soldering iron head does not touch the tin causes and solutions
Soldering iron head in the lead-free soldering process, sometimes there will be a soldering iron head does not stain the phenomenon of tin. Such cases in addition to the quality of the soldering iron head itself, we can also find reasons from other nine aspects:
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、 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: the soldering station is open without using, and the surface of the soldering iron head without tin, will cause the 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:
Is to use a knife to scrape off the oxidized layer of the soldering iron head, exposing the copper that has not been oxidized by the air. Then, put into the rosin box dipped, and then dipped in tin, 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 iron 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.
