摘要:

利用HyperLynx软件对3W规则的有效性进行仿真分析,探索平行微带线的线边距、线长度、介质厚度和介电常数等因素对串扰的影响。分析结果表明,一般情况下,3W规则可以减小约70%的串扰,选取合适的平行微带线参数,可以使3W规则发挥更好的效果。

关键词: 3W规则, 串扰, PCB, 微带线

Abstract:

3W rule is an experiential method of the routing which is used to reduce the crosstalk of the tracks on printed circuit board.The study of its effectiveness is valuable for engineering application.In this paper,we use HyperLynx software to simulate the effectiveness of the 3W rule,and explore the impact of some factors,such as line margins,line length,dielectric thickness and dielectric constant of the parallel microstrip on the crosstalk.The results indicate that the 3W rules can reduce about 70% of the crosstalk in generally.therefore selecting the appropriate parameters of the parallel microstrip line can make the 3W rule work better.

Key words: 3W rule;crosstalk;printed circuit board(PCB);microstrip line
