What causes the soldering iron tip not to stick to solder when soldering with solder wire? How to deal with it?

In general, We are conducting.Solder wireWhy do we often encounter the phenomenon that the soldering iron tip does not stick to the solder during soldering? So, how to solve the problem that the soldering iron tip is prone to blackening and not sticking to the solder during soldering? 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 Solder Paste Manufacturer tell you how to find the cause and the solution if such a situation occurs:

The reasons for this situation usually occur. 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.

6Dry burning of the soldering iron tip, for instance, if the soldering station is not in use 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.

For moregoodTo solve this situation, we can use a small knife to scrape off the oxide layer on the tip of the soldering iron to expose 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 is not thorough enough to remove it, and at the same time, it can be scraped off for a long timeThe tip of the soldering iron will become thinner, affecting heat transfer, causing the temperature to drop, and even damaging the tip of the soldering iron. The disadvantages of using this method are: however, it cannot be cleaned thoroughly by this method. At the same time, if scraped for a long time, the tip of the soldering iron will become thinner, affecting heat transfer, causing the temperature to drop, and even damaging the tip of the soldering iron.

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 the tip of the soldering iron.

The above is a description of some situations that may occur when the soldering iron tip does not stick to solder during wire soldering. You can take a look. If you have any questions, you are welcome to consult Shenzhen JJY Industrial Technology Co., LTD. Let's learn and grow together!
