摘要
I/O接口是笔记本电脑EMI超标的主要来源。通过对笔记本电脑周边接口在印制电路板上的布线和布局进行合理规划,以限制噪声信号随意进出I/O接口;同时对接口连接器在I/O口区域做适当接地可优化笔记本电脑的电磁兼容性。
The I/O connector will be the main EMI source of notebook computer. The Proper layout of the I/O signal trace and placement of the I/O connector will be good to improve the EMI ,and it will keep the noise signal out of the I/O area; At the same time make the I/O connector grounding well on the point of I/O port, it will get well EM compatibility about the notebook computer system,
