Screening Can (Router Shielding Enclosure): A Core Component for Ensuring Stable Network Transmission

2025-10-31

Ⅰ. Technical Parameters: Shielding Guarantee in Line with Industry Standards

The screening can we produce has core parameters strictly aligned with GB/T 18268-2010 Electromagnetic Compatibility Requirements for Electrical Equipment Used in Measurement, Control and Laboratory and IEEE 802.11 series wireless communication standards, ensuring compatibility with various household and enterprise-level routers:

Material Selection: The main body is made of H62 brass or 1060 aluminum alloy, with the surface treated by nickel plating (thickness: 5-8μm) or zinc plating (thickness: 8-12μm). The electromagnetic shielding effectiveness (SE) can reach 60-80dB (test frequency: 30MHz-1GHz), which can effectively block the leakage of electromagnetic radiation and the intrusion of external interference signals.

Structural Design: The integrated stamping forming process is adopted, with a precise gap of 0.1-0.2mm reserved at the joint. It is matched with conductive foam or EMI shielding gaskets to avoid shielding failure caused by assembly gaps. At the same time, customized hole opening is supported (aperture error ≤ 0.05mm) to adapt to the interface layout of different router motherboards.

Temperature Adaptability: The operating temperature range is -40℃~85℃, which meets the internal heat dissipation needs of routers during long-term operation. Moreover, the material has a low thermal expansion coefficient, so there is no risk of deformation during long-term use.

Ⅱ. Functional Value: Solving Core Performance Pain Points of Routers

For router manufacturers, integrating our Screening Can can directly solve three core pain points:

Upgraded Anti-Interference Capability: The electromagnetic radiation generated by the internal CPU and power module of the router will interfere with the transmission stability of the wireless signal module (2.4GHz/5GHz). However, the Screening Can can increase the internal radiation shielding rate to more than 99%, and at the same time block the interference signals from external devices (such as microwave ovens, Bluetooth speakers, and smart home appliances), so that the packet loss rate of the router is reduced to less than 0.5% in a complex electromagnetic environment.

Optimized Signal Coverage: Without a shielding enclosure, the router signal is prone to "directional deviation" due to internal interference, resulting in some areas becoming "signal dead zones". Our Screening Can enables the wireless signal to spread evenly through precise shielding range control, increasing the coverage radius by 15%-20%, and the signal strength difference between different positions in the same space is ≤ 3dB.

Guarantee for Product Compliance: As the requirements for electromagnetic compatibility (EMC) of electronic devices in various countries become stricter (such as EU CE certification and US FCC certification), the Screening Can can help routers pass EMC tests easily, avoiding product launch failure due to excessive radiation and shortening the R&D cycle.

Ⅲ. Supply Advantages: Providing Efficient Support for Manufacturers

As a professional supplier, we can provide full-process services:

Customization Capability: We support the rapid design of exclusive Screening Can according to the router motherboard size and module layout, with a sample delivery cycle of ≤ 7 days.

Mass Production Stability: We have 19 stamping machines, with a monthly production capacity of up to 8,000 units. We have also passed the ISO 9001 quality system certification, and the product defect rate is controlled within 0.1%.

Cost Advantage: Through large-scale procurement and process optimization, we provide manufacturers with competitive quotations on the premise of ensuring quality, helping them control product costs.

At present, our Screening Can has been adapted to Huawei router products and has obtained market verification. If you are a router R&D or manufacturing enterprise and need to improve the anti-interference performance and signal stability of your products, please feel free to contact us to obtain the detailed technical plan and sample testing service of Screening Can.
