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