列车用高速数字PCB电路板抗干扰设计(EMS)

Anti-Jamming Design in High-Speed Digital Printed Circuit Board Used for Train(EMS)

详细阐明了高速数字印制电路板在设计时应该注意的问题,阐明了在列车车载系统中高速数字电路将会受到哪些方面的影响,以及产生这些影响的原因,针对具体问题提出设计高速电路时应该采取的几种方法。实践证明,采取这些方法设计的电路能够极大提高产品的抗干扰性能。

The paper illustrates some attention aspects in designing a high-speed digital printed circuit board,and the high-speed digital printed circuit to be affected by which factors in the train carried system and the reasons for these effects.It also presented some methods to be adopted in designing a high-speed digital printed circuit for the existing questions.According to the practice,the circuit which is designed by these methods can improve the product’s performances and shorten the product’s period of development.
