What should we pay attention to when repairing PCB? Shenzhen Zhongke PCB manufacturer shares with you the precautions for PCB maintenance.
With the continuous development of electronic products, PCB circuit boards have greatly increased the frequency of various equipment failures, and the requirements for maintenance personnel are also increasing. Especially for the maintenance personnel who have just contacted the circuit boards, many people do not know how to start at the beginning, nor how to learn. In fact, to learn the maintenance of circuit boards, they must have a certain foundation of digital and analog electricity.
The schematic diagram of PCB is a blueprint to realize the functions required by circuit users. PCB design mainly refers to layout design, which requires various factors such as internal electronic components, metal wiring, layout of through-hole and external connection, electromagnetic protection, thermal dissipation, crosstalk, etc.
The circuit board needs to know fast, medium speed and vulgar logic circuits, and be placed close to the connector, while the vulgar logic and memory should be placed in the principle connector. In this way, the common impedance coupling, radiation and cross interference can be reduced. PCB circuit board
