Abstract
An interface for mitigating electromagnetic interference (EMI) on a printed circuit board (PCB) is disclosed. The PCB can contain circuit components and includes one or more signal planes sandwiched between corresponding ground planes. The PCB has a first and second side and an interface region separating the first and second sides that includes a partition wall projecting outward from the interface region, configured for EMI shielding between the first side and second sides, one or more pairs of input and output pads straddling the interface region on respective first and second sides and configured to accommodate an EMI line filter, and a ground barrier within the printed circuit board under the interface region. A method of mitigating EMI using the interface is also disclosed.
