Selection and maintenance of soldering iron tips

Troubleshooting and easy selection

01. How to choose the right soldering iron tip quickly and correctly?
It is very important to choose the right size and shape of the soldering tip.
The right soldering tip can make the work more efficient and increase the
applicability of the soldering tip. The size of the soldering tip is directly related
to the heat capacity. When performing continuous soldering, the larger the
soldering tip, the smaller the temperature drop. In addition, because the heat
capacity of a large soldering tip is higher, a relatively low temperature can be
used during soldering, and the soldering tip is not easy to oxidize, which relatively
extends the service life. Generally speaking, the size of the soldering tip is selected
based on not affecting adjacent components. Selecting a geometric size that can
fully contact the solder joint can improve soldering efficiency.

1. i-type (pointed)
Model features: The tip of the soldering iron is sharp and thin
Application: Suitable for fine soldering or in narrow soldering space,
and can also correct solder bridges generated when soldering chips
2. Type B (conical)
Model features: B-type soldering iron tip has no directionality, the entire front end
of the soldering iron tip can be soldered
Application: Suitable for general welding, regardless of the size of the solder joint,
you can use the B-type soldering iron tip
3.D type (slotted screwdriver bit)
Model features: D nozzle can be used for welding on both sides
Application: Suitable for welding that requires a large amount of tin,
such as welding environments with large welding areas, thick terminals,
and large solder joints.
4. Type C (horseshoe)
Model features: Use the front bevel of the soldering iron tip for soldering,
suitable for soldering that requires a large amount of tin
Application: The application range of C-type soldering iron tip is similar to that of D-type
soldering iron tip, for example, it is suitable for large welding area and large welding
5.K type (knife shape)
Model features: Use knife-shaped parts for welding, vertical or pull welding,
a multi-purpose soldering iron tip
Application: The application range of C-type soldering iron tip is similar to that
of D-type soldering iron tip, for example, it is suitable for large welding area, thick
terminals, and large welding.

02. Care and maintenance of the soldering iron tip
1. Maintenance of soldering iron tip
Proper use of the soldering iron tip and regular attention to the care and maintenance
of the soldering iron tip can greatly increase the life of the soldering iron tip. Before
soldering: you must first wet the cleaning sponge with water and then squeeze out
the excess water, so that the soldering tip can be well cleaned. If you use a non-wet
cleaning sponge, the soldering tip will be damaged and the soldering will not be soldered.
2. The order of soldering can protect the solder tip and reduce the oxidation rate
1. Before soldering, clean the old tin on the soldering tip;
2. Perform soldering;
3. No need to clean, and put the soldering iron back into the soldering iron rack;
4. Note: Do not use sandpaper or hard objects to clean the soldering tip.
3. After welding
First, adjust the tip temperature to 250°C, then clean the tip and apply
a new layer of tin for protection.
(If you use a non-temperature-controlled soldering iron, turn off the power
first and let the tip temperature drop slightly before applying tin.)
4. Treatment of welding tip oxidation
First, adjust the tip temperature to about 250°C, then clean the tip with a cleaning
sponge, then tin it, and repeat the process until all the oxide is removed.
5. Other considerations
Try to use low temperature soldering. If the tip temperature exceeds 470°C,
its oxidation rate will be twice that of 380°C.
