【SCM】 highspeedpcbdesign DL : 0: 高速pcb设计指南，在PCB设计中，布线是完成产品设计的重要步骤，可以说前面的准备工作都是为它而做的，在整个PCB中，以布线的设计过程限定最高，技巧最细、工作量最大。PCB布线有单面布线、双面布线及多层布线。布线的方式也有两种：自动布线及交互式布线，在自动布线之前，可以用交互式预先对要求比较严格的线进行布线，输入端与输出端的边线应避免相邻平行，以免产生反射干扰。必要时应加地线隔离，两相邻层的布线要互相垂直，平行容易产生寄生耦合。-High speed pcb design guidelines, in PCB design, wiring are completed an important step in product design, it can be said in front of it ready for the job is done, in the entire PCB, the routing of the design process in order to limit the highest, most techniques fine, the largest workload. Have single-sided PCB wiring wiring, double-sided multi-layer wiring and cabling. Wiring, there are two ways: automatic routing and interactive routing, auto-wiring at before, you can use the interactive more stringent requirements in advance of the line wiring, input and output lines should be avoided adjacent parallel reflection in order to avoid interference. Ground wire should be added the need to isolate two adjacent layers of the wiring should be perpendicular to each other, parallel easily lead to parasitic coupling.
