ABSTRACT:
A PCB is provided that is suitable for use in applications where EMI control is of interest. The PCB includes circuitry that communicates with an edge connector having edge traces located on its surface. Additionally, embedded traces are disposed within the dielectric material of the PCB, and each embedded trace electrically connects an edge trace with a corresponding median trace located on a surface of the PCB. An embedded ground layer substantially disposed within the dielectric material defines an area within the dielectric material through which the embedded traces pass. Finally, one or more vias are provided that extend through the dielectric material of the PCB and are filled with a conductive material. The vias are electrically connected to the embedded ground layer and configured to electrically communicate with an associated module. In this way, a structure is implemented that facilitates control of electromagnetic radiation emitted by the PCB circuitry.
