A well laid out PCB does not radiate much EMI all by itself from the current carrying traces. In order to get EMI compliance a PCB should have:- Ideally six layer PCB with two full ground planes. Four layer PCBs are okay.- Make sure there is sufficient vias between the ground planes.- Make sure to minimize the switching current loops on the board.- Current carrying traces must be kept as short as possible and running on a layer close to the ground plane.- Power ground plane and the signal ground must be connected at only one point.
