To repair electrical appliances, what type of soldering iron is used?
To repair electrical appliances, common tools must have an electric soldering iron, but which one is suitable depends on which type of electrical appliance you are specifically engaged in repairing
The most common repairs, such as refrigerators, washing machines, air conditioners, and simple circuit repairs, are quite useful with ordinary pointed or horseshoe soldering irons. If it is a repair of a mobile phone motherboard, a computer board, or a TV signal motherboard integrated block, due to the dense and numerous pins of the integrated block, it is necessary to have an anti-static soldering station when disassembling.
The specific type of electric soldering iron you have depends on the user's habits and needs
If you want to solder a circuit board, it is best to use a constant temperature soldering iron of around 40-60W, which can adjust the constant temperature and is very convenient to use. I will use this type of soldering iron (as shown in the picture). When soldering a circuit board, it is important to note that the board cannot be soldered with electricity. It is best to ground the grounding wire of the soldering iron. Dry clothes in winter can easily generate static electricity. Before soldering, discharge to prevent induction or static electricity from damaging electronic components. Welding circuit boards requires the use of fine solder wire, which melts quickly, makes it easy to grasp the size of solder joints, and improves the welding quality.
If you want to solder large solder joints in electrical appliances, a low-power soldering iron is not enough. The temperature cannot reach the melting point of the solder and cannot be completely melted, which is prone to false soldering. Therefore, the soldering iron power should be at least 100W or above.
Before welding, it is necessary to adjust the appropriate temperature and master welding techniques. The welding speed should be fast to avoid damaging the circuit board, components or terminals due to scalding, and avoid false soldering. We should constantly summarize our experience, learn by doing, learn by doing, and become proficient over time.
