What should I do if the soldering iron tip doesn't stick to solder during soldering?

In general, We are conducting.Solder wireWhen soldering, it is often encountered that the soldering iron tip does not stick to tin. How can this problem be solved? 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 JJY Tin Wire Factory tell you how to find the cause and the solution if this situation occurs:

Generally, the soldering iron tip does not stick to tin. We need to consider these seven 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.

6"Dry-burning" soldering iron tips, for instance, 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 the air. Then, put it in a rosin box, dip it in, and then dip it in tin. It can 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.

Another step is to immerse the oxidized soldering iron tip into a container filled with alcohol, and then1～2After taking it out in a minute, the oxide was completely and cleanly removed, and the soldering iron tip looked brand new. It has no corrosive effect on soldering iron tips.
