Board maintenance knowledge

Board maintenance knowledge
　　 Board repair is an emerging repair industry. In recent years, the degree of automation of industrial equipment is getting higher and higher, so the number of industrial control boards in various industries is also increasing. After the industrial control board is damaged, the high cost of replacing the circuit board (less than a few thousand dollars, more than Ten thousand or hundreds of thousands of dollars) has become a very headache for companies. In fact, most of these damaged boards are repairable in China, and the cost is only 20% - 30% of the purchase of a new board , and the time spent is much shorter than the time of foreign board. The following describes the basics of circuit board maintenance.
Almost all board repairs have no drawing materials, so many people are skeptical about board maintenance. Although the various boards vary widely, the same is true for each board, which consists of various integrated blocks, resistors, capacitors, and Other devices are formed, so board damage must be caused by damage to one or some of the devices. The idea of ​​board repair is based on the above factors. Circuit board maintenance is divided into two parts: inspection and maintenance, in which the inspection occupies a very important position. A basic knowledge of each device on the board is tested until a bad part is found and replaced, and then a board is repaired. Welcome to the company's official website http://
Board inspection is the process of finding, determining, and correcting every electronic component failure on a board. In fact, the whole testing process is a thinking process and a testing process that provides logical reasoning clues. Therefore, the testing engineer must gradually accumulate experience and continuously improve the level during the maintenance, testing, and maintenance of the circuit board. The general electronic equipment is composed of thousands of components. In the maintenance and overhaul, if you directly check each component in the board to find the problem, it will be very time-consuming and very implementation-oriented. difficult. Then, from the fault phenomenon to the cause of the fault, the check-in type is an important maintenance method. As long as the board detects the problem, the repair is easy. The above is the basic knowledge of circuit board maintenance.
