PCB layout basic principles and design skills-part 2

34. In a circuit with both analog and digital circuits, how to avoid mutual interference when designing the PCB board? If the analog circuit is reasonably matched, the radiation is very small, and it generally interferes. Interference sources come from devices, power supplies, space, and PCB; digital circuits must be interference sources due to many […]

PCB layout basic principles and design skills-part 1

Although there is a lot of software that can realize automatic PCB layout and routing, as the signal frequency continues to increase, engineers need to understand the basic principles and techniques of PCB layout and routing in order to make their designs perfect. The following covers the relevant basic principles and design skills of PCB […]

10 most effective PCB design golden rules

Although the current level of semiconductor integration is getting higher and higher, many applications also have system-on-chips available at any time. Many powerful and out-of-the-box development boards are becoming more and more easily available, but the application of electronic products in many use cases still needs to use custom PCB. In one-time development, even an […]
