Electromagnetic compatibility (EMC) refers to the ability of a device or system to meet the requirements in an electromagnetic environment without causing intolerable electromagnetic interference to any device in its environment. The purpose of EMC design is to make the electronic and electrical products work normally in the expected electromagnetic environment, reduce or malfunction the asexual energy, and do not cause any electromagnetic interference in the electromagnetic environment.
In the design of modern electronic products, EMC (electromagnetic compatibility) design has been paid more and more attention, the era of prosperity EMC design services mainly through the principle analysis, structural analysis, single board device selection analysis and high speed signal simulation SI, PCBLAYOUT wiring analysis and subsequent EMC test and analysis of measures to solve the EMC problem in single board products the design stage.
EMC design is the main content of Kemaolong:
1 、 provide EMC design scheme for the system, including structure, device and so on.
2 、 provide PCB design solution and layout guidance to single board.
3 、 provide the rectification and debugging to the product EMC, propose the solution.
The main features in the design of EMC Kemaolong:
A, the potential sources of interference and the electromagnetic energy sensitive element and a circuit device installed in the PCB, the position of an active element, printed line line, impedance matching, grounding design and so on, we have to consider in the design of EMC, to screen for some components will be PCB.
B and internal cables are typically used to connect PCB or other internal subcomponents, including routing methods and shielded internal cable EMC designs.
C, after PCB's EMC design and internal cable design, we will pay special attention to the shielding design of the enclosure and all the holes, perforations and cable vias
D, in particular, can focus on the input, output, and other cable filtering problems.
