| Abstract: | The printed circuit board （PCB） is the key part to meet the electromagnetism compatibility （EMC） requirements for electronic equipment. Their electromagnetism disturb can be reduced by proper layout of PCB. Some important EMC design rules are brought forward including components placement, ground plane, power line, clock signal treatments. At last, some factual examples of EMC design rules mentioned above are shown and analyzed. |
