The material for customizing shielding covers is usually metal, such as copper, aluminum, steel, or stainless steel.

The shielding cover is an alloy metal cover that is a crucial component for reducing display radiation. When applied in MID or VR products, it can effectively reduce mutual interference between modules

Use of shielding cover

Customization of shielding covers requires comprehensive consideration of technical requirements such as material selection, structural design, manufacturing processes, and electromagnetic compatibility

Material selection

Metal material: commonly used 0.2mm stainless steel (shielding cover) combined with phosphor bronze (shielding bracket), balancing conductivity (phosphor bronze conductivity ≤ 1 Ω· cm) and welding performance; Zinc tin nickel alloy (ZSNH) is suitable for scenarios that require high welding strength. ‌

Non metallic materials: Conductive rubber sealing strip (body resistivity ≤ 1 Ω· cm) is used for joint sealing, and nano silver coating (0.1 μ m thick) can improve high-frequency absorption by 15dB but at a higher cost. ‌

Safety distance

The distance between the cover and the edge of the PCB should be ≥ 1mm to prevent assembly collision; The critical signal path area should avoid the opening design. ‌

Design of heat dissipation holes

Heat dissipation holes with a diameter of 1-1.5mm and a spacing of approximately 5mm balance heat dissipation and electromagnetic sealing; The waveguide ventilation aperture should be ≤ λ/4 (e.g. 2.4GHz corresponds to ≤ 3cm). ‌

Grounding design

Adopting the "2-1-2-1mm" Great Wall foot welding process (contact 2mm, suspended tin climbing 1mm) to ensure grounding reliability and reduce residual radiation intensity by 10-15dB

The prototype can usually be completed within 24-48 hours.

Quick prototyping services are provided to ensure suitability or functionality, allowing for low-cost design modifications and identifying improvements in manufacturability before achieving mass production.
