PCB设计的一般原则[分享]
印制电路板(PCB)是电子产品中电路元件和器件的支撑件．它提供电路元件和器件之
间的电气连接。随着电于技术的飞速发展，PCB的密度越来越高。PCB设计的好坏对抗干扰能力影响很大．因此，在进行PCB设计时．必须遵守PCB设计的一般原则，并应符合抗干扰设计的要求。要使电子电路获得最佳性能，元器件的布局及导线的布设是很重要的。为了设计质量好。造价低的PCB．应遵循以下一般原则：
1.布局
首先，要考虑PCB尺寸大]]>https://blog.youkuaiyun.com/toddhan/article/details/5738174https://blog.youkuaiyun.com/toddhan/article/details/5738174toddhanThu, 15 Jul 2010 21:03:00 +0800
