1Object-affected harmful factors
If separate shield structures are provided for each electronic component, then electromagnetic interference is effectively blocked, but the device size and weight increase
Solution Approach 1:
Multiple separate shield structures for different electronic components are merged into a single integrated shield structure that simultaneously shields multiple components. The shield structure includes a first shield portion for a first electronic component and a second shield portion for a second electronic component, forming one unified assembly that reduces overall weight and complexity while maintaining electromagnetic shielding effectiveness for all components.
