计算机操控低辐射技术的研究

Research of Low Electromagnetic Field Emission of Computer Manipulative Parts

提出了计算机操控部件低辐射设计的要素,包括数字器件的处理、I/O接口的滤波、按键走线的处理、静电防护和屏蔽。阐述了各个设计要素的基本处理方法。在实际设计操控部件时,需要根据各个要素降低辐射的效果和具体实现的难易进行有重点的设计。

This paper proposes some essentials of design for low electromagnetic field emission of computer manipulative parts.The essentials consist of the management of digital components,the filtering of I/O interface,the disposal of keyswitch route,static prevention and shielding.Basic solution of every essential is expatiated.During the idiographic design,the effect of reducing emission and the difficulty of material realization should be taken into account.
