The PCB circuit board is based on an insulating board and is cut to a certain size. At least one conductive pattern is attached to it, and holes (such as component holes, fastening holes, metallized holes, etc.) are arranged to replace the electronic components of the previous equipment. The chassis of the device and the interconnection between the electronic components are completed.

    PCB circuit board repair is a new type of repair work. In recent years, the degree of automation of industrial equipment has become higher and higher, so the number of industrial control boards for each job is also increasing. After the industrial control board is damaged, the high cost of replacing the PCB circuit board (as few as several thousand yuan, as many as Tens of thousands or hundreds of thousands of yuan) has also become a very headache for enterprises.

    Most of these damaged PCB 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 basic knowledge of PCB circuit board repair.

    Almost all PCB circuit board repairs do not have drawing materials, so many people are skeptical about PCB circuit board repair. Although various circuit boards are different, the constant is that each PCB circuit board is composed of various integrated blocks, resistors. , capacitors and other devices, so the damage to the PCB must be caused by the damage of one or some of the devices.

    The idea of PCB circuit board repair is based on the above elements. Circuit board repair is divided into two parts: inspection and repair, during which inspection plays an important role. Test the basic knowledge of repair for each device on the PCB circuit board, until the bad parts are found and replaced, then a PCB circuit board is repaired. High precision pcb circuit board

    PCB circuit board inspection is the process of finding, acknowledging and correcting the shortcomings of each electronic component on the PCB circuit board. In fact, the entire inspection process is a process of thinking and supplying logical reasoning clues. Therefore, inspection engineers must gradually accumulate experience and continuously improve the level in the process of PCB maintenance, inspection, and overhaul.

    General electronic equipment is composed of countless components. During maintenance and repair, it will be very time-consuming and difficult to implement if you directly inspect each component in the PCB circuit board to find the problem. . Then the check-in type maintenance method from the defect phenomenon to the defect reason is an important maintenance method. The PCB circuit board only needs to detect the address of the problem, then the repair is very simple.
