How to Use a Hot Air Gun – iPhone Motherboard Repair Tips
One of the most commonly used tools in phone repair is the hot air gun, which requires a high level of technical expertise on the part of technicians. In both the process of soldering and desoldering motherboard components, a hot air gun is required.

Types of Hot Air Guns

Today we will walk you through some basic knowledge of hot air gun in phone repair. Hot air guns come in two main types: helical wind and vertical wind.

Helical Wind Type:
1. imarily used for soldering and desoldering larger components like connectors, NAND, CPUs, and WiFi modules.
2. Features gentle airflow and lower heat output.
Vertical Wind Type
- Ideal for soldering and desoldering small components such as resistors and capacitors.
- Offers concentrated airflow and higher heat levels.
Proper Use of Hot Air Guns

Proper utilization of the hot air gun can improve repair effectiveness, but improper usage may harm the phone. Different scenarios require specific temperature and airflow settings for the hot air gun. If the temperature is too low, component removal becomes impossible and soldering will be flawed. Conversely, high temperatures can cause damage to components and the PCB board.

What’s more, components will get blown away if the airflow is set too high. Therefore, proper use of the hot air gun is the key to phone repair

Then we will show you how to use hot air gun properly for phone repair. First of all, let’s take a look at how to desolder small components. Vertical wind hot air gun is used to desolder these kinds of components.

The temperature should be set around 330 °C-365 °C and airflow around 1-3. Because the vertical wind hot air gun heats up so quickly, please wait to begin working until the temperature is stable after starting up.

In addition, the nozzle should be kept vertical from the component with a distance of 3-6 mm. You should heat evenly above the component for about 13-18 seconds. Then remove the component with tweezers.

For soldering, the soldering method is the same as the desoldering method. You need to put the component in position firstly and pay attention to the temperature as well as airflow.

Next, let’s see how to desolder large chips with hot air gun. Corner adhesive needs to be removed when we use hot air gun to desolder large chips like NAND. Helical wind hot air gun is used to desolder these kinds of large chips. Please apply high-temperature tape around the component to protect surrounding components.

The temperature should be set around 365 °C-400 °C and airflow around 45-65. The nozzle should be kept vertical from the component with a distance of 6-8 mm.

You should heat evenly above the component for about 40 seconds. Then pry up the component with a pry blade.

In summary, the nozzle of hot air gun should be kept vertical from the soldering surface with a suitable distance. Other than that, the temperature and airflow of the hot air gun must be set properly according to the actual repair circumstances.

Please note that the temperature sometimes has to be adjusted according to the type of fixture. The synthetic stone fixture dissipates heat slowly, and the temperature can be lower.

The iron fixture dissipates heat quickly, and the temperature should be set higher.

Most motherboard repairs will use a hot air gun. Choosing the right one will make your repair easier with high efficiency. Two in one hot air gun has always been a hot-selling product in the phone repair industry. REWA Selected recommends the 2 in 1 SUGON 8620 hot air gun to you.

The hot air gun heats up quickly with multiple nozzles. You can easily switch between helical and vertical wind directly by changing the nozzle to achieve different application scenarios.

Besides that, its design is also very user-friendly, easy to use, and easy to place.

Choosing the Right Hot Air Gun

Selecting the right hot air gun is essential for efficient repairs. Consider two-in-one hot air guns like the SUGON 8620, which offers quick heating and versatility with multiple nozzles for various applications.

Conclusion

Mastering the use of a hot air gun in phone repair is crucial for successful repairs. Follow these guidelines, use the right tool, and maintain proper temperature and airflow settings to ensure efficient and damage-free phone repairs. For top-quality hot air guns, check out the SUGON 8620 at the REWA shop. Leave your thoughts on hot air gun usage in the comments section below.

When not in use, it’s advisable to keep the machine head and host close to each other to prevent the tube from tangling with other objects and to maintain a reasonable tube bend.

Quick 861DW Host Display

The front view of the host showcases the power button, temperature adjustment controls, channel selection, and a display. The rear panel contains features such as input voltage options, grounding holes, and fuses. The station also includes four waterproof platforms on the bottom for added stability and anti-static protection.

Quick 861DW Gun Head and Holder Features

The gun’s air outlet is located at the top, and the nozzle is securely attached here. When using the gun, always hold the upper plastic housing to avoid burns, as the metal parts can get extremely hot. The nozzle’s thickness plays a crucial role in enabling the host to enter sleep mode when not in use. Placing the gun head in the holder triggers increased cooling airflow until the station enters sleep mode and shuts down.

As a precision tool, the hot air gun requires careful handling to maintain temperature accuracy and stability. Here are some essential precautions to keep in mind:
- Be cautious of high air outlet temperatures after use to prevent burns.
- Always place the gun in the holder after use and let it enter sleep mode before turning it off completely.
- Ensure the air outlet is unobstructed.
- Maintain a distance of at least 2 mm between the air outlet and any object.
- Only turn off the power when the temperature has cooled to 100 degrees or less.
- Avoid aiming the gun at the human body while working.
