What kind of electric soldering iron is used to repair electrical appliances
To repair electrical appliances, a common tool must have an electric soldering iron, but which one is suitable depends on what kind of electrical appliances you are specifically engaged in...
For the most common repairs, such as refrigerators, washing machines, air conditioners, and simple circuit repairs, an ordinary pointed or horseshoe soldering iron is very easy to use. If it is mobile phone motherboard repair, computer board repair, TV signal motherboard integrated block, etc., due to the large number of pins of the integrated block, an anti-static welding station must be used when disassembling.
What kind of electric soldering iron you have depends on the user's habits, and the second is based on the needs of use...
If you want to solder the 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 kind of soldering iron (as shown in the picture). When soldering the circuit board, pay attention to the fact that the circuit board cannot be soldered with electricity. The grounding wire of the electric soldering iron is best grounded. Drying clothes in winter is prone to static electricity. Discharge before welding to prevent electronic components from being damaged by induced electricity or static electricity. Weld the circuit board with thin solder wire, which melts quickly, easy to grasp the size of the solder joints, and the welding quality is also good.
If you want to solder 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 false solder, so the soldering iron power must be at least 100W.
Before welding, adjust the proper temperature and master the welding skills. The welding speed should be fast to avoid scalding the circuit board, components or terminals, and avoid false welding. We must constantly sum up experience, learn by doing, learn by doing, and become proficient after a long time.
