Beryllium Copper Fingerstock for Reliable Enclosure Shielding
Maintain consistent EMI/RFI shielding across enclosure seams while supporting long-term mechanical performance.
Shielding Challenges at Enclosure Interfaces
Enclosure seams, doors, panels, and access points are common sources of EMI/RFI leakage. Even small gaps or inconsistent contact pressure can significantly reduce shielding effectiveness, especially in applications subject to vibration, thermal cycling, or repeated access.
Beryllium Copper Fingerstock provides a resilient, conductive interface that maintains electrical continuity across enclosure joints while accommodating movement and tolerances.
A Proven Approach to Enclosure Shielding
Fingerstock shielding uses spring-based metal contacts to create reliable grounding paths between mating surfaces. This approach helps control EMI/RFI leakage without requiring permanent bonds, making it well suited for enclosures that require frequent opening or service.
Beryllium Copper is commonly selected for its combination of electrical conductivity, spring properties, and durability under repeated compression.
