Three things to pay attention to when repairing PCB circuit boards

With the continuous development of electronic products, the frequency of various equipment failures has greatly increased, and the requirements for maintenance personnel are also increasing, especially for maintenance personnel who have just contacted circuit boards . I know how to start, and I don't know how to learn. In fact, if you want to learn the maintenance of PCB circuit boards, you must have a certain foundation of digital and analog electricity.

The schematic diagram of the PCB circuit board is a blueprint to realize the functions required by the circuit users. The design of the PCB circuit board mainly refers to the design of the layout, which requires various factors such as the layout of internal electronic components, metal connections, through holes and external connections, electromagnetic protection, heat dissipation, and crosstalk.

Circuit board manufacturers need to know fast, medium-speed, and low-end logic circuits, which should be placed in the area close to the connector, while low-end logic and memory should be placed in the area of the principle connector. In this way, it is beneficial to reduce common impedance coupling, radiation and crosstalk. What are the precautions for PCB circuit board maintenance? The following briefly introduces the precautions for circuit board maintenance:

1. Before maintenance, do anti-static work first, such as wearing anti-static work clothes and shoes, and wearing anti-static wrist straps. The maintenance workbench should also do anti-static treatment, such as adding anti-static countertops.

2. Pay attention to the safety of electricity use, including considering the maximum bearing capacity of the circuit board when powering on the circuit board for maintenance .

3. When you need to contact strong electricity, you must pay attention to personal safety and take measures to prevent strong electricity.
