| + | [* black] Hot air guns can be divided into the helical wind and vertical wind types. The helical wind type is mainly used to solder and desolder connectors, NAND, CPU, WiFi modules and other relatively large chips. |
| [* black] The vertical wind type is mainly used to solder and desolder small components like resistors and capacitors. | |
| [* black] The helical wind type features gentle airflow and low heat, while the vertical wind type has concentrated airflow and high heat. |
