A rigid PCB is the most traditional form of board in the PCB world. Common multi-layer PCB circuit boards are generally 4-layer boards or 6-layer boards, and complex multi-layer boards can reach more than a dozen layers. There are both high-speed logic circuits and linear circuits on the circuit board. They should be separated as much as possible, and the ground wires of the two should not be mixed, and they should be connected to the ground wires of the power supply. To maximize the ground area of the linear circuit. So how should the PCB circuit board be maintained?
With the explosive growth of wearable devices, flexible display and smart devices, the demand for FPC has increased significantly, the industry is getting more and more widely used, and the local flexible circuit board industry has gradually entered the outbreak period.
In daily life, the composition of various electronic devices inevitably requires the use of PCB circuit boards.
ternary lithium battery PCB is a chemical battery using lithium as negative active material.
A PCB circuit board is a support for circuit components and devices in electronic products. Even if the circuit schematic is designed correctly, the improper design of the printed circuit board will adversely affect the reliability of electronic products. When designing a printed circuit board, attention should be paid to using the correct method, complying with the general principles of PCB design, and should meet the requirements of anti-interference design.
