Abstract
To address potential electromagnetic interference (EMI) issues in highly dense electronic circuits, where electric components and interconnections are integrated in proximity, we investigated the effectiveness of integrating a noise suppression sheet (NSS) inside printed circuit boards (PCBs). We fabricated NSSs compatible with PCB embedding and systematically evaluated their noise suppression performance. Using a newly proposed measurement jig to simulate the embedding of NSSs in PCBs, we confirmed the suppression effect of conduction and radiation noise. We also embedded NSSs in PCBs used in actual products and confirmed the validity of PCB-integrated NSS for suppressing radiation noise in the frequency range of 700MHz to 1GHz, which is widely used for telecommunications.
