Knowledge of white light soldering station
Soldering Station Overview
The soldering station adopts the latest composite soldering tip, which combines the heating element and the soldering tip into one, and the heating is very fast, and it is very easy to replace the soldering tip. The body of the white light soldering station is particularly compact, with a vertical design to save work space. It is equipped with a fault signal device. When the temperature of the welding tip is lower than the minimum alarm range, or the parts such as the heating core and the circuit board are faulty, the white light soldering station will sound a fault Signal to alert staff to check. Anti-static design, coupled with 15V output design, can protect components from being damaged by leakage voltage impact. Plug-in temperature control prevents the staff from changing the welding temperature at will.

Operation of the soldering station
1. How to better use the tip of the soldering iron
1. Before welding work
Wet the cleaning sponge with water first, then squeeze out the excess water. Only in this way can the white light soldering iron head get the best cleaning effect. If you use a non-moist cleaning sponge, it will damage the tip of the soldering iron and cause it to not tin.
2. When performing welding work
The following soldering sequence can protect the tip of the soldering iron and reduce the oxidation rate.
3. After welding work
First adjust the temperature to about 250°C, then clean the tip of the soldering iron, and then add a new layer of tin for protection. (If you use a non-temperature-controlled soldering iron, cut off the power first, and let the temperature of the soldering iron tip drop slightly before tinning.)
4. Precautions
a. Try to use low temperature welding
High temperature will accelerate the oxidation of the soldering iron tip and reduce the life of the soldering iron tip. If the temperature of the soldering iron tip exceeds 470°C, it will oxidize twice as fast as 380°C.
b. Do not apply excessive pressure
When soldering, do not apply too much pressure, otherwise the tip of the soldering iron will be damaged and deformed. As long as the soldering iron tip can fully contact the solder joint, heat can be transferred. In addition, choosing the right soldering iron tip can also help heat transfer.
c. Always keep the tip of the soldering iron on tin
This can reduce the chance of oxidation of the soldering iron tip and make the soldering iron tip more durable. After use, new solder should be added after the temperature of the soldering iron tip has dropped slightly, so that the tin plating layer has a better anti-oxidation effect.
d. Keep the tip of the soldering iron clean and remove oxides immediately
If there is black oxide on the tip, the tip may not be tinned and must be cleaned immediately. When cleaning, first adjust the temperature of the soldering iron tip to about 250°C, then clean the soldering iron tip with a cleaning sponge, and then tin it. Repeat the action until the oxide is cleaned up.
e. Choose flux with low activity
Fluxes with high mobility or strong corrosiveness will accelerate the corrosion of the soldering iron tip when heated, so low corrosive fluxes should be selected. NOTE: Never use sandpaper or hard objects to clean the soldering iron tip.
f. Put the soldering iron on the soldering iron stand
When not using a soldering iron, the soldering iron should be placed carefully on a suitable soldering iron stand to prevent the soldering iron tip from being damaged by collision.
g. Choose the right soldering iron tip
It is very important to choose the correct size and shape of the soldering iron tip. Choosing the right soldering iron tip can make the work more efficient and increase the durability of the soldering iron tip. Choosing the wrong soldering iron tip will affect the soldering iron's inability to perform at its peak efficiency, and the soldering quality will also be reduced as a result.
The size of the soldering iron tip is directly related to the heat capacity. The larger the soldering iron tip, the larger the heat capacity, and the smaller the soldering iron tip, the smaller the heat capacity. When performing continuous soldering, use a larger tip for less temperature drop. In addition, because the heat capacity of the large soldering iron tip is high, a relatively low temperature can be used during soldering, and the soldering iron tip is not easy to oxidize, which increases its life.
The short and thick soldering iron tip conducts heat faster and the thinner soldering iron tip is faster and more durable. A flat, blunt tip will transfer more heat than a sharp tip. Generally speaking, the size of the soldering iron tip is based on not affecting adjacent components. Choosing a geometry that allows adequate contact with the solder joint can improve soldering efficiency.
Second, the use and maintenance of soldering iron
(1) About cleaning sponge
Before each use of the cleaning sponge, it should be fully soaked in water, then fully squeezed and placed in the soldering iron stand. The purpose of this is to prevent the soldering iron tip from directly contacting water at high temperature and accelerate oxidation. It should be pointed out that the role of the cleaning sponge is to test the residual tin and oxides on the tip of the soldering iron, and do not throw or knock the tin.
(2) About the maintenance of the soldering iron head
The tip of the soldering iron is a consumable item. Correct use and maintenance can greatly extend the life of the tip of the soldering iron. First of all, before using the new soldering iron tip for the first time, be sure to adjust the temperature of the soldering iron to 220 degrees, so that the tinned part of the soldering iron tip can fully absorb the tin. It is best to soak it in the tin pile for 5 minutes, and then wipe it on a cleaning sponge Try it clean, and adjust the temperature of the soldering iron to 300 degrees again, repeat the above procedure, and finally adjust the temperature of the soldering iron to the required temperature for use. The purpose of this is to form a protective film on the tin layer on the tip of the soldering iron to prevent direct oxidation of the new soldering iron tip at high temperature. Before leaving get off work every day, wipe the tip of the soldering iron on the cleaning sponge, and then apply a little fresh solder. Before using it on the first day, try to wipe the tip of the soldering iron on the cleaning sponge, and then use it after re-tinning. By operating in the above way, the service life of the soldering iron tip can be maximized. It should be pointed out that the temperature of the soldering iron tip should not be too high. The higher the temperature, the shorter the life of the soldering iron tip. It is generally recommended to use a temperature of 350 degrees. Under normal circumstances, when the soldering iron is used at a temperature of 350 degrees and works 8 hours a day, and is maintained according to the normal maintenance procedures, the service life of the soldering iron tip is generally about 30,000 solder points.
