The shape of the tip of the soldering iron
1. The shape of the soldering iron head of commonly used direct heating soldering irons is mostly chisel-shaped, similar to the chisel style used by fitters. According to the requirements of the surface to be welded, the chisel tip angles include 45° and 10-25°, and the widths are also different. When welding products with high assembly density, in order to avoid burning the surrounding components and wires and to facilitate access to deep solder joints, an extended chisel-type soldering iron tip can be used.
Among the above-mentioned chisel-type soldering iron tips, the heat is concentrated at a large angle and the temperature drops slowly, which is suitable for welding general solder joints; the temperature drops quickly at a small angle and is suitable for welding components that are sensitive to temperature.
2. The tapered soldering iron tip is suitable for soldering smaller solder joints of small electronic devices.
3. Internally heated electric soldering irons commonly use round beveled tips, which are suitable for soldering printed circuit boards and general solder joints.
4. When using an internally heated electric soldering iron to weld printed circuit boards, you can use notched soldering iron tips and hollow core soldering iron tips. Using these two soldering iron tips can make welding more convenient, but the trimming of these two soldering iron tips is more troublesome.
Specifications of soldering iron tips
Type I
Features: The tip of the corresponding soldering iron tip is very small.
Scope of application: The soldering iron tip of this specification is very suitable for fine welding, and it can also be used in places where the welding space is relatively small.
B type/LB type
Features: This B-type soldering iron tip has no certain directionality, and the entire front end of the soldering iron tip can be welded. Type LB can be said to be a type of type B. Both sizes of soldering iron tips are very flexible.
Scope of application: This specification can be used for general welding, regardless of the size of the solder joint.
D type/LD type
Features: Use the nozzle part for welding.
Scope of application: Suitable for welding that requires a large amount of tin, such as a welding environment with a large welding area, thick terminals, and large soldering pads.
Type C/Type CF
Features: The bevel of the corresponding front end of the soldering iron tip is used for welding processing, which is very suitable for welding with large amounts of tin.
Scope of application: It can be used for welding that requires a large amount of tin, such as in environments with large welding areas.
K type
Features: The knife-shaped part is used for welding. It can be used for both vertical and pull welding types. It is a multi-purpose soldering iron tip.
Scope of application: It is very practical for correcting tin bridges and soldering connectors.
H type
Features: The corresponding tin plating layer is located at the bottom of the soldering iron tip.
Scope of application: QFP can be used for pull welding and some SOPs with larger welding pitches.
