Abstract: As the fast development of electronic technology, electronic products of high density and high frequency increase rapidly. This will bring on a further deterioration of the electromagnetic environment and cause a series of electromagnetic compatibility problems. To eliminate the interference between every part of circuit and reduce the conductive emission and radiation emission, EMC design of PCB are widely overviewed,which will ensure the products pass the electro magnetic compatibility testing.
