Abstract: Presented herein is a printed circuit board (PCB) assembly with an absorber having a perforated structure. The absorber is positioned between a trace of a PCB and a connector that couples the PCB to an enclosure. The absorber includes a perforated structure to maintain an integrity of a signal propagated along the trace, while improving electromagnetic interference and/or electromagnetic compatibility properties.
