Electromagnetic compatibility design of PCB
For small power digital integrated circuit, choose 0.2-0.5mm line width. In the same PCB, the ground and power cables should be wider than the signal cables.

Design of electromagnetic compatibility based on PCB
Therefore, the interference source and propagation path of electromagnetic interference must be analyzed. Common electromagnetic interference in PCB design includes conduction interference, crosstalk interference and radiation interference.
Electromagnetic compatibility in printed circuit board (PCB) development techniques
Electromagnetic compatibility in the design of printed circuit board (PCB) involves many factors, the following mainly from three parts to be elaborated, the specific selection to integrate various factors.
PCB design techniques to improve electromagnetic compatibility of circuit boards
In order to suppress the cross talk between the printed circuit board wires, in the design of wiring should be as far as possible to avoid long distance equal wiring, as far as possible to open the distance between lines, signal lines and ground and power
How to improve electromagnetic compatibility during board design process
In the process of high-speed circuit design, we must consider how to deal with the radiation of the power supply and the interference to the whole system. Generally, the area of the power layer plane should be smaller than the area of the ground plane, so
Lift the "cap" of PCB board electromagnetic compatibility
From the point of view of function, the hole can be divided into two categories: one is used as an electrical connection between the layers; The second is used for fixing or positioning devices. In terms of technological process, through holes are general
Design of controllability and electromagnetic compatibility of high speed PCB
There is a little bit of short circuiting between digital and analog, but note that there is only one connection point. There are also differences on the PCB, which is determined by the system design.
How to do electromagnetic compatibility design in PCB design and wiring?
How to do electromagnetic compatibility design :1. Suitable wire width,2. Key points of component wiring,3. Wiring rules for high frequency and high speed signals
Electromagnetic compatibility in PCB design
When the field strength of electromagnetic field exceeds a certain limit and the operation time is long enough, it may endanger human health. It can also interfere with other electronic devices and communications. All of these need to be protected.
Analysis of power supply and Ground interference in PCB electromagnetic Compatibility design
In the design of PCB electromagnetic compatibility, the main problem that needs attention is the interference problem of power supply and ground.
Reasonable PCB design for electromagnetic compatibility
high speed circuit design technology has become the electronic system designers must take the design means. The controllability of the design process can only be achieved by using the design techniques of high speed circuit designers.
Electromagnetic compatibility considerations in PCB design
n electronic product that does not conform to EMC specifications is not an acceptable electronic design. In addition to meeting market functional requirements, design products must also adopt appropriate design techniques to prevent or relieve EMI effects
