What kind of soldering iron is used to repair electrical appliances
Repair of electrical appliances, common tools must have a soldering iron, but specifically which is appropriate, it depends on your specific engaged in the repair of home appliances which kind of appliances...
The most common repairs, such as refrigerators, washing machines, air conditioners, simple circuit repairs, the use of ordinary pointed or horseshoe head soldering iron is quite good. If it is a cell phone motherboard repair, computer board repair, TV signal motherboard integrated block, etc., because of its integrated block pin fine number of numerous, disassembly must have anti-static soldering station.
Specifically have which kind of soldering iron, one is the user's habits, the second is based on the need to use...
If you want to solder circuit boards, it is best to use a thermostatic soldering iron of about 40~60W, which can be adjusted to a constant temperature, and is very convenient to use, and I use this kind of soldering iron (as shown in the picture). Welding circuit boards should pay attention to the circuit board can not be charged welding, soldering iron grounding wire is best to ground, dry clothes in winter are prone to static electricity, welding should be discharged before, in order to prevent induced electricity or static electricity will be damaged electronic components. Welding circuit boards to use fine solder wire, so that the melting fast, easy to grasp the size of the solder joints, welding quality is also good.
If you want to weld electrical appliances in a very large soldering point, small power soldering iron will not work, the temperature does not reach the melting point of the solder and can not be completely melted, easy to false soldering, so that the power of the iron should be at least in the 100W or more.
Before welding to adjust the appropriate temperature, but also master the welding skills, welding speed should be fast, to avoid scalding the circuit board, device or terminal, and do not false welding. To constantly summarize the experience, dry learning, learning to dry, long time to be skilled.
