Maintenance Tips for Soldering Iron Tips
1. Before starting welding work
It is necessary to wet the cleaning sponge first, and then squeeze out the excess water. This is the only way to achieve the best cleaning effect for the soldering iron tip. If a non moist cleaning sponge is used, it may damage the soldering iron tip and prevent soldering.
2. When performing welding work
The following welding sequence can provide solder protection for the soldering iron tip and reduce oxidation rate.
3. After welding work
First, adjust the temperature to about 250 ° C, then clean the soldering iron tip and add a layer of new tin for protection. (If using non temperature controlled soldering iron, cut off the power first and let the temperature of the soldering iron tip slightly decrease before soldering.)
4. Precautions
a, Try to use low-temperature welding as much as possible
High temperature can accelerate the oxidation of the soldering iron tip and reduce its lifespan. If the temperature of the soldering iron tip exceeds 470 ° C, its oxidation rate is twice that of 380 ° C.
b, Do not apply too much pressure
When welding, do not apply too much pressure, otherwise it may damage and deform the soldering iron tip. As long as the soldering iron tip can fully contact the solder joint, heat can be transferred. Choosing the appropriate soldering iron tip can also help with heat transfer.
c, Regularly keep the soldering iron tip tinned
This can reduce the oxidation chance of the soldering iron tip and make it more durable. After use, wait for the temperature of the soldering iron tip to slightly decrease before adding new solder to improve the oxidation resistance of the tin plating layer.
d, Keep the soldering iron tip clean and promptly remove oxides
If there is black oxide on the soldering iron tip, it 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 solder it. Repeat the action continuously until the oxide is removed.
e, Choose low activity soldering flux
Fluxes with high activity or strong corrosiveness will accelerate the corrosion of soldering iron tips when heated, so low corrosiveness fluxes should be selected. Note: Do not use sandpaper or hard objects to clean the soldering iron tip.
f, Place the soldering iron on the soldering iron frame
When the soldering iron is not needed, it should be carefully placed on a suitable soldering iron holder to avoid damaging the soldering iron tip due to collision.
g, Choose the appropriate soldering iron tip
Choosing the correct size and shape of the soldering iron tip is very important. Choosing the right soldering iron tip can make work more efficient and increase the durability of the soldering iron tip. Choosing the wrong soldering iron tip can affect the soldering iron's maximum efficiency and reduce the soldering quality.
The size of the soldering iron tip is directly related to its 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 welding, the larger the soldering iron tip used, the less the temperature drop. In addition, due to the high heat capacity of the large soldering iron tip, a relatively low temperature can be used during soldering, making the soldering iron tip less prone to oxidation and increasing its lifespan.
