Product Description
Custom High-Frequency Stamped Grounding Fingers for 5G Base Stations
Tingfeng Hardware provides custom grounding fingers for 5G Massive MIMO antennas, specializing in complex spring forms. Manufactured from BeCu C17200 with 60–90 dB shielding effectiveness, a 0.5–4.0 mm compression range, and stress relief heat treatment for stable contact force under outdoor thermal cycling. With 16 years of precision manufacturing experience, we help telecom equipment clients address long-term outdoor deployment reliability challenges and the consistency requirements of large-scale antenna arrays.
Product Overview
5G AAUs contain dozens to hundreds of densely packed RF channels, each requiring reliable low-impedance grounding to suppress inter-channel interference. Our BeCu grounding fingers feature complex spring form designs, conductivity of approximately 22% IACS, multi-contact redundancy that reduces single-point failure risk, and stress relief heat treatment that prevents stress relaxation under -40°C to +85°C outdoor cycling. On the commercial side, 5G deployment is shifting from "coverage first" to "O&M efficiency and long-term reliability first." Clients need grounding solutions that maintain performance consistency over years of outdoor service and reduce field maintenance needs. Our full-batch force testing and material traceability system respond directly to this requirement.
