First, you need to take courses so as not to break client devices.
Training in modular phone repair can be taken in the IQ center.
Suitable for beginners. Teachers are working masters of service centers. Share their many years of experience.
And if you have already mastered the basic knowledge of phone repair and are planning to do component repair, then the BGA soldering course is suitable for you.
And phones are not so easy to repair now, every year manufacturers try to make devices less and less disassembled, fewer and fewer parts are replaceable. Once it was hard to imagine that the owner would not be able to remove the cover and change the battery himself. Okay, if you have some kind of display cable or something like that fell off - you can still solder neatly, but if the elements are smaller? You will not scalp the processor if the communication modem is covered?
