What kind of soldering iron to use to repair electrical appliances?
To repair electrical appliances, a common tool must be a soldering iron, but which one is suitable depends on what kind of household appliance repair you are engaged in...
For the most common repairs, such as refrigerators, washing machines, air conditioners, and simple circuit repairs, an ordinary pointed or horseshoe-shaped soldering iron is very useful. If it is mobile phone motherboard repair, computer board repair, TV signal motherboard integrated block, etc., because the integrated block has a large number of pins, an anti-static soldering station must be used during disassembly.
The specific type of soldering iron to own depends on the user's habits and the needs of use...
If you want to solder a circuit board, it is best to use a constant temperature soldering iron of about 40~60W. It can adjust the constant temperature and is very convenient to use. I use this soldering iron (as shown in the picture). When welding a circuit board, be careful not to weld the circuit board with electricity. It is best to ground the ground wire of the soldering iron. Static electricity is easily generated when drying clothes in winter. Discharge before welding to prevent induction or static electricity from damaging electronic components. When welding circuit boards, use thin solder wire, which melts quickly, makes it easier to control the size of the solder joints, and improves the welding quality.
If you want to weld large solder joints in electrical appliances, a low-power soldering iron will not work. The temperature cannot reach the melting point of the solder and cannot be completely melted. It is easy to cause false soldering. Therefore, the power of the soldering iron must be at least 100W.
Before welding, you must adjust the appropriate temperature, master the welding skills, and the welding speed must be fast to avoid burning the circuit board, components or terminals, and avoid false welding. We must constantly sum up experience, learn by doing, learn by doing, and over time you will become proficient.
