How to solve the problem of solder not sticking to the tip of a soldering iron?

Due to the differences in mechanical structure, function and application, the main purpose of an electric soldering iron is to solder components and wires. When we are doing solder wire soldering, we often encounter the phenomenon that the soldering iron tip does not stick to solder. How can we solve this problem? In fact, there are many reasons for the non-adhesion of tin. We can only look for these problems and solve them. Now, let's have JJYTin wire manufacturerLet me tell you all about how we should look for the cause and the solution if such a situation occurs:

Generally, the soldering iron tip does not stick to tin. We need to consider the following factors:

1The quality issue of the soldering iron itself should be taken into consideration.

2Choosing a temperature that is too high can easily cause the soldering iron tip's tin-dipping surface to undergo severe oxidation.

3The tin-dipped noodles were not eaten with tin before use.

4Use incorrect or defective cleaning methods.

5The use of impure solder or flux interruption in the solder wire.

6For "dry-burning" soldering iron tips, if the soldering station is left unused and there is no tin on the surface of the soldering iron tip, it will cause rapid oxidation of the soldering iron tip.

7Contact with organic substances such as plastics, lubricating oils or other compounds.

To better address this situation, we can use a small knife to scrape off the oxide layer on the tip of the soldering iron, exposing the copper that has not been oxidized by air. Then, put it in a rosin box to dip it in, and finally apply tin. It can then be used normally. However, this method cannot clean thoroughly. Meanwhile, if scraped for a long time, the soldering iron tip will become thinner, affecting heat transfer, causing the temperature to drop, and even damaging the soldering iron tip.

Also, immerse the oxidized soldering iron tip into a container filled with alcohol and take it out1~2After a few minutes, the oxide will be completely and cleanfully removed, the soldering iron tip will look brand new, and there will be no corrosive effect on the soldering iron tip.
