Abstract
Electromagnetic shields for sub-modules of electronic modules are disclosed. Electronic modules may include multiple sub-modules arranged on a substrate with an electromagnetic shield arranged to conformally cover the sub-modules as well as portions of the substrate that are uncovered by the sub-modules. Electromagnetic shields are disclosed that are configured to extend between sub-modules to form one or more divider walls. The one or more divider walls may be configured to extend below mounting surfaces of electronic components in the sub-modules to provide improved reduction of electromagnetic interference (EMI) or crosstalk between various sub-modules. Electromagnetic shields are also disclosed that form perimeter sidewalls that extend below mounting surfaces of electronic components of sub-modules to provide improved reduction of EMI from other modules or other external sources.
