科技发展至今,几乎所有的工程设计都和电子设备相关,随之而生的电磁兼容(EMC)指标已经成为电子设备设计中的重要内容。电磁兼容设计涉及电路设计、PCB布线、电缆设计、系统布局、结构设计等多方面问题,甚至与软件设计都有关系。本文将基于电磁兼容的概念,从结构设计的角度,在选材,结构形式等方面提出一些设计思路及方案,以期从结构上提高设备的电磁兼容性。 Since the development of science and technology, almost all the engineering design is related to electronic equipment. The ensuing electromagnetic compatibility (EMC) index has become an important part of electronic equipment design. EMC design involves circuit design, PCB layout, cable design, system layout, structural design and many other issues, and even have a relationship with the software design. This article will be based on the concept of electromagnetic compatibility, from the structural design point of view, in the selection of materials, structural forms and other aspects of the design ideas and programs in order to improve the structure of the electromagnetic compatibility.
