Board mount EMI enclosures are metal or conductive housings designed to be mounted directly onto a PCB to shield sensitive components from electromagnetic interference (EMI) and radio frequency interference (RFI).

Key Features:

• Shielding effectiveness: 60–100 dB typical
• Materials: Tin-plated steel, nickel silver, aluminum, or conductive plastics
• Mounting: SMT or thru-hole pins, solder tabs, or clip-on designs
• Removable lids for post-assembly access
• Available with gaskets for enhanced RF sealing

Applications:

• Wireless modules (Wi-Fi, Bluetooth, Zigbee)
• High-speed digital circuits
• Medical and automotive electronics
• Consumer devices (smartphones, tablets)

Selection Criteria:

1. Frequency range of concern
2. PCB footprint and height constraints
3. Thermal dissipation needs
4. Serviceability (removable lid vs. sealed)
5. Cost and volume requirements

Note: Proper grounding via multiple perimeter contacts is critical for effective shielding.
