What are some challenging things to learn about mobile phone repair?

The challenging thing of mobile phone repair is manual technology, soldering chips, the most important thing is the life of the circuit, as a person who repairs mobile phones, we must understand the circuit, we must understand the circuit, we must distinguish the circuit of the mobile phone, there are boot circuits, audio circuits, ** circuits, power circuits, etc., there are many things, when repairing the circuit, it is necessary to use the universal meter, to learn to measure the circuit, this is my experience in repairing mobile phones, I recommend it to everyone! <>

There are still many challenges in mobile phone repair, and there are things to learn.

Would you fix a phone now? The answer is that I won't repair my phone, inadvertently is a simple, can learn the job, he is also very difficult, such as changing some parts, ordinary people really can't do it, last time I put the memory module on the computer with my classmates, neither of us put it in, but I went to the store and put it in three seconds, we are really embarrassed, so there are still a lot of things to learn in mobile phone repair, and changing the screen is also a difficult thing to learn.

As long as you are willing to work hard, everything can be learned.

When it comes to mobile phone repair, there are still a lot of challenging things to learn. If you think that mobile phone repair is very simple, then you can try to learn to refine the mobile phone motherboard, you have to learn the knowledge of chip circuits, I think this is definitely enough for you to learn. Plus, I think you can learn how to fix a broken screen.

Apple mobile phone's wifi, audio, hard disk, power amplifier, etc., these single problems are relatively easy to repair. If you can power the power, the CPU, then you're pretty much there. And then some theoretical knowledge.

Knowledge of the characteristics and functions of individual components. Basically, you can repair the motherboard separately.

Mobile phone repair is actually a very difficult industry, because there are too many parts in the software of this mobile phone, if you are not careful, you will break the parts as much as possible, once damaged, those mobile phones will basically be scrapped, so you must be particularly careful when repairing, and you must have professional knowledge, so that you can find the problem of the mobile phone in time.

Mobile phone repair is an extremely demanding and careful work, which requires you to understand the internal situation of the mobile phone and the application of software, as well as the structure and character of the internal configuration of the mobile phone, so it is difficult to complete the mobile phone repair without enough knowledge.

I think the most challenging thing in phone repair is the phone film, because the phone film is a very difficult activity. When you are applying the film to the phone, you have to make sure that there are no bubbles after the application is completed. It is also necessary to ensure that the film is positive. You can't deviate from it.

If you really want to learn something challenging, you can learn to repair the circuit board of the mobile phone, or replace the memory of the mobile phone, etc., so that it may seem that you are very skilled.

Mobile phone repair is one, requiring patience and carefulness, just like a doctor to see a patient, to have professional knowledge, mobile phone repair is more difficult is the motherboard, because there are more solder joints, to understand the function of each solder joint, now there are not many motherboards, more is the main thing is to change the screen, changing the screen is very simple, as long as you are careful.

The integrated chip of the mobile phone is very complex, and because it is relatively small, it is more inconvenient to repair, and now some of the higher technology can also replace the processor, as well as Apple's memory expansion and the like, these are more complicated, and one is accidentally broken.

Repairing a mobile phone is not difficult to learn.

Repairing a mobile phone only requires strong hands-on ability, and it can be learned. As long as you control this technology, you can change the screen, microphone, earpiece and other bad faults can be avoided. It can repair 60% of the faulty machines on the market.

So repairing a mobile phone is not difficult to learn.

Learn the key points of mobile phone repair:

1. Hands-on ability, chip splints.

It is mainly used for heat guns and other equipment to butt weld the chip splint on the motherboard, reloading and other operators, which are mostly limited to mobile phones that have been dropped! Refuse to be skillful in repairing equipment, and after control, you can repair 30% of the faulty machines on the market.

2. Thinking ability, fault identification.

According to the circuit understanding of various rare chips, the analysis draws conclusions to identify and search fault points. It is necessary to systematically and comprehensively learn the basic principles of mobile phone repair. Belonging to the theoretical course, you must be literate!

After control, it can independently identify the difficult repair of various mobile phones, and if it is necessary to face such incurable diseases as ordinary customers, it only accounts for about 10% of the market. At present, 90% of the repairers on the market belong to the first 2 options. He and the hungry people can still open the store!

From this, it can be concluded that it is not necessary to have a high degree of education to repair a mobile phone, only the third option must be understood, because it must be used in the future to analyze drawings or find information. <>

There is no prospect for learning mobile phone repair, the analysis is as follows:

1.With people's requirements for timely communication of information, mobile phones are the best choice, and the number of mobile phones will be more and more, and it is impossible to be eliminated without use. No one dares to say how many more years humans will live on Earth, so the prospects for repairs are good.

2.Some people say that mobile phone repair can't be reported anymore, and now mobile phones are too cheap. In fact, the most important thing to repair a mobile phone is to have good technology, in order to have the courage to repair it in order to report **, if you buy a machine for 500 yuan with two months to repair it to you to repair it for 50 yuan, are you willing to repair?

If you don't fix it, then you will be a big money, and you can be described as a loser.

What's more, one-time consumption is not recommended in the future, mobile phones are also a symbol of status, everyone is willing to buy a better and more expensive one, especially after a mobile phone is used to it, he will definitely spend money to repair.

3.With more and more brands in the mobile phone consumer market, more and more advanced technology and functions, and faster product upgrading, the lag of mobile phone after-sales service is exacerbated, and the more bad opportunities are, and the more software failures can be charged if you set it casually.

4.Due to the very high probability of mobile phone failure, coupled with the uneven quality of mobile phones, the imperfection of the service after the sale and burial of the mobile phone repair has increasingly become an emerging hot industry. The market needs a large number of high-level maintenance personnel.

5.Due to the high degree of integration of mobile phones, the maintenance difficulty is not large, as long as you understand its working principle, many faults are caused by virtual soldering of components, such as faults other than the motherboard, such as changing the handset, transmitter, display screen, case wiring and other common faults are very much, do not learn, as long as you watch others do it a few times, you should be able to learn, according to statistics, 80-90% of the mobile phone repair shops on the street have not systematically learned, and their business is not the same booming.

6.After learning how to repair mobile phones, you can move into other electronic repairs. For example, in the future, you can teach yourself the repair of video cameras, other high-end electronics, because you have already entered the radio gate.

7.In the early stage of learning to repair the mobile phone, you can focus on repair, and when your technology improves and your reputation goes out, you can also take your apprentices to wholesale machines and so on to do business related to mobile phones, because you already understand this industry, and you are no longer a layman.

8.Learn to repair mobile phones and easily open a shop, not under the control of others, do your own business, not lukewarm, not tired, live a relaxed and happy life, as long as you are popular, you can speak, do not worry about no business.

There are three main ways to learn mobile phone repair.

1. Go to the local maintenance shop to find a master as an apprentice, generally there are such maintenance shops willing to recruit apprentices, lucky to have a monthly salary (not very high), while learning and repairing, the effect of learning depends on the level of the master you are looking for;

2. Go to a technical school with a mobile phone repair major, systematically learn mobile phone repair technology, if the school is responsible, so that the learning can combine theoretical knowledge and practice, and can quickly enter the mobile phone repair industry;

3. Self-study, now the network is rich in knowledge, and easy to obtain for free, so you can learn relevant skills on the Internet, so it depends on the learner's talent, if you don't understand, you can also find like-minded friends on the Internet to discuss learning, or combine self-study with practice, you can try to do while learning.

In short, the master leads the door, the cultivation is personal, and everything has to be done by yourself, otherwise any method is useless.

The learning time required to repair a mobile phone is as follows:

1. Some software problems such as jailbreaking, unlocking, and obtaining permissions of the mobile phone can be learned in just 15 days.

2. Understand the circuit diagram and general disassembly, which only takes about 1 month to learn.

3. It takes about 2 months to understand the circuit diagram and be able to repair the mobile phone simply.

4. It takes 3 months to understand the circuit diagram and reach the level of a general skilled master.

5. And more advanced, to become a top mobile phone repair engineer, it depends on your own efforts, and there is no end to learning.
