PCB板图设计的一般原则与注意事项VIP专享VIP免费

【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 PCB 在整个电子产品中，扮演了整合连接总其成所有功能的角色。 本文通过 Protel 软件和几个典型的例子探讨了整个 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，分析了各种干扰产生的途径和原因，介绍了 PCB设计中的一些特殊规则及抗干扰设计的要求。【关键词】：印刷电路板、 电路辅助设计、规则、 技巧、 布线技术、 电磁干扰 、PCB PROTELABSTRACTAltium 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 introd...
