The Avalon 821 PMU is a high-performance power management unit commonly used in consumer electronics such as smartphones and tablets. When manufacturing these electronic products, many electronic components need to be soldered onto the PCB, including the Avalon 821 PMU. This article will show you how to properly solder the Avalon 821 PMU and other electronic components, and provide you with a detailed video guide.

First, gather the necessary tools and materials. You will need a hot air gun, an electric soldering iron, flux, solder wire, desoldering braid, alcohol cleaning agent, cotton swabs, and gloves. Ensure that your workspace is safe, well-ventilated, away from flammables, and out of reach of children and pets.

Next, open the video guide and follow these steps:

1、Preheat the soldering area using a hot air gun to achieve the appropriate temperature. This will help evenly and stably spread the solder during soldering.

2、Apply a layer of flux to the soldering area. This helps remove surface oxidation, making it easier for the solder to spread and connect to the pads.
3、Place the solder wire on the pad and place the soldering iron between the wire and the pad. Heat the pad and the wire until the solder wire fully melts and connects to the pad.

4、After soldering, use desoldering braid to remove excess solder. Be sure to dispose of the removed solder safely.

5、Repeat the above steps until all components are soldered onto the PCB.
6、Clean the soldering area with cotton swabs and alcohol cleaning agent to remove any remaining flux and solder.

7、Carefully inspect all solder joints to ensure they are even, strong, and free of cold solder or short circuits.

By following these steps, you can properly solder the Avalon 821 PMU and other electronic components. Be sure to use appropriate safety measures and always be aware of fire and electrical shock hazards
