The cause of soldering iron head crawling tin and the treatment method for soldering iron head crawling tin
The problem of soldering iron head crawling tin
The electric soldering iron head has been in use for a long time, and when the soldering iron head is used again, it will be found that the tin wire will run towards the soldering iron head, commonly known as running tin (crawling tin).
The upward movement of tin is mainly related to the chromium plating layer. The function of chromium is to prevent tin from moving upwards. After using the soldering iron head for a period of time, the chromium layer will be wiped off, and when the chromium layer is wiped off, it will cause tin to move upwards.
Crawling or running tin refers to the process of sticking tin to other parts after passing the tin coating on the soldering iron head. Therefore, the reason why the soldering iron head runs upwards is directly related to the chromium layer, which is very common in soldering.
The Reason for Tin Crawling on the Electric Soldering Iron Head
1. The reason for the product itself is that the outer layer of the soldering iron head is chrome plated too thin or the chrome layer is not properly disposed of.
2. There are many impurities in the rosin flux inside the tin wire, which can easily corrode the chromium plating layer of the soldering iron head at high temperatures, leading to tin crawling.
Treatment method for soldering iron head crawling tin
1. Return to the factory to replace products with thicker chrome plating or better treatment.
2. Replace the tin wire with good quality and low impurity content. Reducing the working temperature appropriately can improve the phenomenon of tin climbing;
3. Purchase an alloy soldering iron head with a special anti tin melting layer treatment on the surface, which can prevent tin from peeling off and extend its service life.
The function of chrome plating is only to prevent tin from crawling. Crawling tin will appear on any electroplated soldering iron head, and the original packaging is no exception, but it only appears sooner or later.
The above introduces the common reasons for electric soldering iron head crawling tin, as well as the treatment methods for electric soldering iron head crawling tin, hoping to be helpful to everyone.
