Studying the impact of shielding cabinet dimensions on cavity resonance

As electronic components become more densely packed on printed circuit boards (PCBs), the risk of electromagnetic interference (EMI) due to unintended coupling increases. To optimize the performance of integrated circuits (ICs) and ensure electromagnetic compatibility (EMC), the use of board-level s...

description	As electronic components become more densely packed on printed circuit boards (PCBs), the risk of electromagnetic interference (EMI) due to unintended coupling increases. To optimize the performance of integrated circuits (ICs) and ensure electromagnetic compatibility (EMC), the use of board-level shields (BLS) becomes essential in mitigating EMI in PCB designs. The shielding cabinet (also known as a shielding can) is the most common component used for BLS. By connecting to the PCB's reference plane, it provides five of the six walls required to form a Faraday cage. Although it is an effective solution in terms of shielding effectiveness (SE), it can lead to undesired effects such as cavity resonance problems. This study investigates the impact of cabinet dimensions on the cavity resonance frequency using a Finite Element Method (FEM) simulation modeling that is corroborated through an experimental measurement technique.
