Characteristics of welding head

Type I (extremely small) Features: welding head is extremely small. Scale of use: It is suitable for precise welding, or when the welding space is narrow, it can also correct the tin bridge when welding chips. Type b /lb (conical) features: type b welding head has no directionality, and the whole front end of welding head can be welded. Type lb is a kind of type b, and its shape is slender. Able to operate flexibly in the welding environment with tall components around the welding spot or narrow welding space. Scale of use: Suitable for general welding, regardless of the size of solder joints, B-type welding head can also be used.

D-type /ld-type (one-word nozzle shape) features: welding with nozzle part. Scale of use: Suitable for welding with large amount of tin, such as welding environment with large welding area, thick terminals and large welding pads. C-type /cf-type (bevelled cylinder) features: welding with the bevel part at the front end of welding head, which is suitable for welding with a large amount of tin. Only the bevel part of cf welding head has tin coating, and only the bevel part can be stained with tin during welding. Therefore, the amount of tin is different from that of C welding head, which depends on the welding requirements. Welding head of 0.5c, 1c/cf, 1.5cf, etc. are very precise, which is suitable for welding small components, or correcting tin bridges and columns during external welding. If only a small amount of solder is needed for welding, it is more suitable to use cf welding head with tin plating only on the inclined plane; 2c/2cf, 3c/3cf welding head, suitable for welding resistors, diodes and other components, sop and qfp with large pitch can also be used; 4c/4cf, suitable for thick terminals and grounding on circuit boards.

K-shaped (knife-edge) features: it can be welded by knife-shaped parts, vertical or pull-welded, and belongs to multi-purpose welding head. Use scale: it is suitable for welding soj, plcc, sop, qfp, power supply, grounding components, correcting tin bridges, connectors, etc. H-shaped features: tin plating is at the bottom of welding head. Use scale: it is suitable for sop and qfp with large pitch in pull welding.
