Base stations, optical modules, routers and other telecom infrastructure professional shielding solutions. High shielding efficiency (≥90dB), large-size customization, carrier-grade reliability—providing critical shielding support for global communication networks.
Unlike consumer electronics, telecom equipment demands absolute reliability and performance optimization.
≥90dB@1GHz shielding efficiency using copper or gold-plated treatment, accommodating base station multi-band RF circuit isolation. Thickness design 0.8~1.5mm, supporting multi-cavity isolation.
Support maximum size 80×80mm and beyond, providing multi-layer structure and complex partition solutions. Stamping precision ±0.05mm meeting high-density integration requirements.
Operating temperature -40~70℃ (some reaching 85℃). All environmental durability tests: vibration, salt-spray corrosion, thermal cycling. 15+ year operational lifespan requirement.
Specialized high-frequency shielding design for SFP/QSFP optical modules. Ultra-small form (<10mm), precision design, optional thermal and cooling optimization.
Base stations require shielding 5G/4G/3G multi-band operation. Multi-cavity frame design achieves complete band isolation avoiding cross-band interference and intermodulation.
Long-term partnership with three major carriers, deep understanding of equipment integration standards. Support rapid design iteration, short-term prototyping, fast batch delivery.
