Maintenance course of miner's control board

1. I don't have a tutorial. If you have any questions, please come to me. I'll help you answer when you have time. Do it, brother. In fact, computer maintenance is very simple. It can be done after graating from high school. I can't tell you much about it for a while and a half. Join my team and learn more

2. First of all, judge the cause of the fault. You can confirm the cause of the fault through observation, component measurement or circuit analysis. Then, replace the faulty components and test whether they return to normal. You can find Wang Wenzhong's video course of instrial control circuit board maintenance to systematically learn the circuit board maintenance technology.

4. It mainly depends on which part of the circuit board you are repairing. If you have a computer motherboard, automotive electronic air conditioning and other household appliances, you will have the corresponding professional maintenance technical manual. You can only have certain electronic and electrical technology

5. "Instrial circuit board chip level maintenance from introction to Mastery", "instrial circuit board chip level maintenance diagram", these two circuit board maintenance books are relatively easy to understand, can be used as an introctory course for learning.

6. Self taught mobile phone, computer maintenance tutorial materials can be downloaded, from the entry to proficient, very good Oh! You can go to, of course, Liu Qiang 300 lecture tutorial also includes in it, high definition of their own money to buy, can see the free full set of

7. The first step is self-study. The first thing we do is to select reliable circuit board maintenance books or circuit board maintenance teaching videos. Here we recommend "instrial circuit board chip level maintenance from introction to Mastery" and "instrial circuit board chip level maintenance color diagram". These two textbooks are good learning materials for the instry

OK, we have found the introctory course of circuit board maintenance, so the next step is how to learn systematically

2 / 5
in the second step, we should learn to understand the components in the circuit board, mainly their characteristics and functions in the circuit board, such as chip capacitor, resistor, diode, triode, IGBT, etc

then, we need to learn how to use all kinds of circuit board maintenance tools, such as multimeter, digital bridge, oscilloscope, capacitance meter, welding gun, etc. only by correctly mastering the use of these tools can we lay a practical foundation for the future circuit board maintenance work. After all, circuit board maintenance work is a skill based ability, and it is useless to have theory alone<

check the remaining one diagram
3 / 5
the third step, we need to master the circuit board maintenance technology, and also need to have some classic circuit analysis ability, which is helpful to make an accurate judgment of the circuit board fault on the whole

if the circuit analysis is done well, the maintenance can get twice the result with half the effort<

4 / 5
Step 4, we should learn to carry out field maintenance and replacement work for each component of the circuit board. This requires repeated practice to improve their ability, so as to improve the accuracy and efficiency of detection and replacement work. We can find some discarded circuit boards to carry out the practical operation of this work. The purpose is not to repair the discarded circuit boards, but to practice

5 / 5
the last step is to carry out the practical operation of circuit board maintenance. This step requires the accumulation of experience. It is better to have experts to give advice. It is suggested that beginners can take part in training or find a maintenance company to recruit apprentices to accumulate experience. There is a good teacher with Fu can let you less grope for several years, this value is still very high

8. Find Wang Wenzhong instrial control circuit board maintenance video tutorial to follow.

9. Repair circuit board to find professional maintenance personnel

10. If you really like it, just join the after-sales or factory of the manufacturer to learn something.
