One-piece shields are cheaper and more robust but require desoldering for rework. Two-piece shields allow the frame to be soldered once, with a removable cover for easy component access.
RF Shields Component Intelligence
Engineered EMI suppression for high-frequency board-level designs.
What are RF Shields components?
RF shields are critical for containing EMI in high-frequency designs. Selection hinges on board footprint, mounting method (SMT/TH), and material attenuation properties. Always verify thermal dissipation requirements, as shields can trap heat near sensitive components.
How to Choose RF Shields Components
Selecting the right shield requires balancing electromagnetic performance with mechanical constraints.
Mounting Style
Choose SMT for automated assembly or through-hole for high-vibration environments.
Material & Plating
Match material to frequency range; nickel-silver or tin-plated steel are common for corrosion resistance.
Thermal Management
Ensure the shield height allows for airflow or integrate thermal interface materials (TIM) if the shield acts as a heat sink.
Accessibility
Consider two-piece designs if you need to access components for tuning or rework without desoldering the entire frame.
Footprint Constraints
Verify keep-out zones around the shield to prevent shorting to adjacent traces or components.
