Shielding in any form can protect electronic equipment by enabling sensitive circuits and devices to function closely together amidst multiple electromagnetic (EM) fields. Whether to guard against EM interference (EMI) or radio-frequency interference (RFI), shielding comes in many shapes and sizes, from raw materials to finished enclosures.
Understanding the capabilities of available EMI/RFI shielding can help when searching for a solution to suppress EM and/or RF as electronic circuits shrink, with components and interconnections being designed closer together.
