With the continuous development of electronic products, the number of failures of various devices has increased significantly, and the requirements for maintenance personnel, especially those who have just touched the circuit board, are also getting higher and higher. Many people started. I don't know how to start or what's going on. To learn and maintain PCB boards, you need to master the basic knowledge of digital and analog electronics.
The schematic diagram of the PCB board is a diagram that realizes the functions required by the circuit user. The design of the patch mainly requires the layout design of internal electronic components, metal connection holes and external arrangement, electromagnetic protection, heat dissipation, blue crosstalk, etc.
When maintaining the PCB board, pay attention to the following solar energy:
1. Before performing shoe maintenance, you must first do anti-static work, such as wearing anti-static overalls, wearing a cover, and wearing an anti-static wrist strap. The inspection work surface should also be treated with anti-static treatment, such as adding an anti-static table.
2. When turning on the power supply and maintaining the circuit board, pay attention to energy saving, including the load capacity of the PCB circuit board.
3. If you must contact with strong current, pay attention to personal safety and take measures to avoid strong current.
