随着现代电子科学技术的发展,现代电子设备系统功能的增多,使电子设备结构日趋复杂,而且由于系统内部元器件和功率密度的增加,再加上各种内外干扰源,使得整个系统的电磁环境变得极为恶劣。正因为此,电子设备抗电磁干扰技术成为我国电子行业电子设备结构设计中一项重要研究内容。对于电子机箱的信息辐射泄漏或外部辐射的电磁干扰,屏蔽技术是最为有效的一种手段。
With the development of modern electronic science and technology, the increase of functions of modern electronic equipment system makes the structure of electronic equipment more and more complicated. Moreover, due to the increase of internal components and power density in the system, various internal and external sources of interference make the whole system of electromagnetic The environment has become extremely poor. Because of this, the anti-electromagnetic interference technology of electronic equipment has become an important research content in the electronic equipment structure design of China’s electronics industry. Shielding techniques are the most effective means for informational radiation leakage from electronic enclosures or electromagnetic interference from external radiation.
