In fact, the whole testing process is the thinking process and provide logical clues to the testing process, so the testing engineer must be in the circuit board maintenance, testing, overhaul process, gradually accumulate experience, continuously improve the level. General electronic equipment is composed of thousands of components, in maintenance, overhaul, if the direct one by one test to check each component in the circuit board to find the problem will be very time-consuming, implementation is also very difficult. Then, it is an important maintenance method to check the fault phenomenon to the fault reason. As long as the circuit board detects the problem, the maintenance is easy. The above is the basic knowledge of circuit board maintain.
