大专毕业论文基于Protel的PCB版图设计与抗干扰技术的研究.docVIP

【摘要】 Protel是Altium公司推出的电路辅助设计系统,是第一个将所有的设计工具集 成于一身的板级设计系统。在原理图已完成的基础上利用Protel进行PCB设计一 般遵循：确定外形、布局、布线、规则检查等几个步骤。分析了布局、布线的基本 原则,探讨了在整个PCB设计过程中的一些经验和技巧。原理图绘好后,接着是设计印制电路板,简称PCB.进行PCB设计一般遵循:规划电路板、装入元器件封装库及网络表、元器件的布局、布线等步骤本文通过Protel 软件探讨了整个PCB设计过程,为正确高效率设计印制电路板提供了有效的途径ABSTRACT Altium Launches Protel are circuit-aided design system, is the first of all the design tool set Into the boards in a system-level design. In the schematic diagram has been completed based on the use of Protel for PCB design 1 As followed: identification of shape, layout, wiring, a few steps, such as rule checking. Analysis of the layout, the basic wiring . The principle of the entire PCB design process in some of the experience and skills. After schematic drawing, followed by design Printed circuit board, or PCB. For PCB design in general follow: Planning circuit boards, components into the package database and network tables, the layout of components, wiring and other steps in the entire PCB Electronics products, played a total integrated into all the features of their role. ??? In this paper, Protel DXP software and a few typical examples of the entire PCB design process, in order to correct and efficient design of printed circuit board provides an effective way to analyze a variety of interference generated by the ways and reasons, the introduction of the PCB design some special rules and anti-jamming design. 【KEY WORD】: Printed circuit board 、design rules、 auxiliary circuit、 wiring technology skills 、EMI PCB 、PROTEL software 目 录 一、引言 1页 二、软件介绍 1页 三、干扰的来源和传播途径 4页 四、PCB板图设计的一般原则及注意事项 .5页 五、抑制干扰源的常用措施 6页 六、总结 8页 七、参考文献 8页 八、致谢 9页 引言 我国正处在以经济建设为中心和改革开放的大好形势下电子工业的年增长率会超过20%，印刷电路板工业依附整个电子工
