How to learn to repair electronic products,

Learning electronic product maintenance, it is best to have a foundation. There is no foundation, on the one hand, tuition is hard, on the other hand, new electronic products appear slowly;

Then it is necessary to analyze the future development trend, just like CRT TV in the past. Most of the previously updated technologies are ineffective and can only be used as experience. Repairing LCD needs to learn new knowledge, and repairing electronic products needs to keep pace with the times. Learning skills can't last a lifetime, and you need to constantly update your knowledge.

If it is a hobby, the foundation is not very important. If you plan to engage in maintenance work for a long time, you should learn the basics well, update your knowledge to keep up with the times, and then welding technology. In the future, most electronic products are mounted, and the pins of many chips are about 100 feet. Machines are used for production, and manual welding is used for maintenance, which requires high welding technology.

Take a good look at digital circuits and analog circuits, electrical principles and the use of multimeters, which are the most basic.
