Soldering iron tip shape
1, commonly used direct-heat soldering iron soldering iron head shape more made of chisel type, similar to the pliers use chisel style. According to the requirements of the surface of the object to be welded, chisel type soldering iron head angle of 45 ° and 10 ~ 25 ° and so on several kinds, width is also different. In the welding assembly density of products, in order to avoid burns around the components and wires, but also to facilitate access to the depth of the soldering point, can be used to extend the shape of the chisel iron tip.
2, conical iron head, suitable for welding small electronic devices, smaller soldering points.
3, endothermic soldering iron commonly used round bevelled iron head, it is suitable for welding printed circuit boards and general soldering points.
4, the use of endothermic soldering iron welding printed circuit board, you can use the notch iron head and hollow core iron head. The use of these two kinds of iron head can make the welding more convenient, but these two kinds of iron head trimming more trouble.
The specifications of soldering iron tip
Type I
Characteristics: The tip of the corresponding soldering iron tip is very small.
Application scope: This specification of the soldering iron tip for fine welding is very suitable, and then for welding space is relatively small place will also be used.
B type/LB type
Characteristics: This B type soldering iron head does not have a certain direction, for the whole of the front of the iron head are able to weld the LB type can be said to be a type of B type. These two specifications of the iron head are very flexible.
Range of application: for general welding can use this specification, regardless of the size of the soldering joint can be used.
D type/LD type
Characteristics: Soldering with the batch nozzle part.
Application: Suitable for soldering that requires a large amount of tin, such as soldering a large area, thick terminals, solder pads, large soldering environments.
C type/CF type
Characteristics: Using the corresponding front end of the soldering iron tip for soldering treatment, it is very suitable for the soldering of multi-tin quantity.
Application scope: For some need more tin amount of welding, like welding area large environment can be used.
K type
Characteristics: The use of knife-shaped part of the welding, for the vertical type and pull welding type are able to weld, is a multi-purpose soldering iron head.
Application: It is very useful for soldering the corrected solder bridge and connectors.
H type
Characteristics: The corresponding tin layer is located at the bottom of the iron head.
Scope of application: For the pull soldering type corresponding to the soldering of a larger distance between some of the SOP, QFP can be used.
