What is hot air heat gun for?
2023-07-31
The hot air heat gun is mainly composed of an air pump, a linear circuit board, an airflow stabilizer, a casing, and a handle assembly. Some hot air gun handles are made of special high-temperature-resistant high-grade engineering plastics, with a temperature resistance level of up to 300°C; some of the blower parts use a powerful noise-free blower with a service life of more than 30,000 hours to meet the high-power spiral wind output; some of the hot air cylinders use spiral The disassembly structure; some heating wires use special detachable replaceable heating cores.
The heat gun is mainly a tool for welding and picking components by using the hot air blown from the gun core of the heating resistance wire.
Heat gun is one of the most used tools in mobile phone repair, and the process requirements are also very high. Heat guns are used for everything from removing or installing small components to large integrated circuits.
The main use of the heat gun:
1. Remove CPU
Remove the nozzle of the air gun when removing the CPU, adjust the temperature of the heat gun to 6, adjust the scale of the heat gun to 7-8, and adjust the air volume to 7-8. The actual temperature is 280-290 degrees. Grasp, such as: 3508 CPU, blow the wind gun to the four sides of the CPU at an angle and try to blow the hot air into the bottom of the CPU so that it is easy to blow off the CPU intact.
2. Main board disconnection processing
3. Desoldering
To remove or solder plastic cable seats or keyboard seats is the same as some array bells and remove power amplifiers. The main thing is to master the heat and air volume of the heat gun.
4. Blow welding
