What is the function of the heat gun of the welding station
It is used to disassemble the patch chip, which is the main function of the heat gun on the soldering station. The heat gun is a tool that uses the hot air blown out of the gun core of the heating resistance wire to solder and remove components.
When it is necessary to replace a packaged chip such as BGA/LQFP, a sharp-nosed or knife-edge soldering iron will not come in handy. Of course, except for experienced electricians, they have no problem using LQFP packaged devices and quick disassembly with a knife-edge soldering iron.
The heat gun has become a magic weapon. A heat gun and a pair of tweezers can quickly complete the disassembly without the risk of damaging the pad.
The second practical function of the heat gun is to quickly solder SMD components.
Use a soldering iron to apply a thin layer of tin on the pad to be soldered, then clamp the component with tweezers, place it in the corresponding position, and heat it with a heat gun to quickly solder the circuit board. It is generally best to use a small mouth heat gun.
In the process of using the electric soldering iron, you must develop good usage habits. After using the electric soldering iron every time, turn off the power or adjust the temperature to the lowest level to prevent the soldering iron tip from being oxidized and tinned.
Generally, there is flux in the tin wire. When there is no flux such as rosin, you can use tin wire to melt the soldering iron around to protect the use of the soldering iron tip.
Precautions for welding operation
1) Lead accounts for a certain proportion in the welding wire composition. Lead is harmful to the human body. You need to wear gloves or wash your hands after operation to avoid ingestion.
2) The chemical substances volatilized when the flux is heated are harmful to the human body. When the human nose is too close to the tip of the soldering iron during operation, it is easy to inhale the harmful gas. Generally, the distance between the nose and the soldering iron is not less than 30cm, and generally 40cm is appropriate.
3) Use a soldering iron to configure a soldering iron stand, which is generally placed on the right front of the workbench. After the electric soldering iron is used, it must be placed on the soldering iron stand safely, and attention should be paid not to touch the soldering iron tip with wires and other objects.
