Experience and understanding of high-speed PCB design

High-speed PCB design has become the main stream in digital system design,and it affects the performance directly even the function of the system.Following the step of PCB design,the principles of the PCB design are classified with the experience of author according to the high speed PCB design requirement.The principles for high-speed PCB design about PCB stackup,components' placement,ground method and PCB layout are given out in detail,it also shows some problems that should be noticed during PCB design.The high speed PCB designed follows the rules mentioned in this paper and has low ground bouncing and good EMC performance.
