Circuit board repair is an emerging repair industry. 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. Hundreds of thousands of yuan) has also become a very headache for enterprises. In fact, most of these damaged circuit boards can be repaired in China, and the cost is only 20%-30% of the purchase of a new board, and the time used is much shorter than the time spent abroad. The following introduces the basics of circuit board repair.

Almost all circuit board repairs do not have drawing materials, so many people are skeptical about circuit board repair. Although various circuit boards vary widely, the constant is that each circuit board is composed of various integrated blocks, resistors, capacitors and It is composed of other devices, so the damage to the circuit board must be caused by the damage of one or some of the components. The idea of ​​circuit board maintenance is based on the above factors. Circuit board repair is divided into two parts: inspection and repair, in which inspection occupies a very important position. Test the basic knowledge of repair for each device on the circuit board, until the bad parts are found and replaced, then a circuit board is repaired.

Circuit board inspection is the process of finding, determining and correcting the faults of each electronic component on the circuit board. In fact, the entire testing process is a thinking process and a testing process that provides logical reasoning clues. Therefore, testing engineers must gradually accumulate experience and continuously improve the level in the process of circuit board maintenance, testing, and overhaul. General electronic equipment is composed of thousands of components. During maintenance and repair, it will be very time-consuming and very time-consuming to directly test and check each component in the circuit board to find problems. difficulty. So from the fault phenomenon to the cause of the fault, the check-in type maintenance method is an important maintenance method. As long as the circuit board detects the problem, the repair is easy. The above is an introduction to the basics of circuit board maintenance.
