Principles
-
Surface Reflection: When electromagnetic waves come into contact with the copper painting surface, most of them are directly reflected due to the difference in properties between the copper painting and air. This is the main function of shielding.
-
Internal Absorption: A small amount of electromagnetic waves that penetrate the surface are "captured" by the conductive/magnetic components in the copper painting. Their energy is converted into heat and dissipated, preventing further transmission.
-
Secondary Attenuation: Even if there are remaining electromagnetic waves that are not absorbed, they will be reflected again on the inner wall of the copper painting, further weakening their energy until they completely lose the ability to transmit.
-
Consumer Electronics: Casings for mobile phones, laptops, and smart watches
→ Shield radiation from internal chips while resisting external complex signal interference, preventing call disconnections and data transmission lag.
-
Industrial Control: Casings for PLC controllers, sensors, and frequency converters
→ Isolate strong electromagnetic interference in industrial environments, ensure equipment accuracy, and prevent deviations in production data.
-
Automotive Electronics: Casings for in-vehicle navigation systems, radars, and battery management systems (BMS)
→ Block high-frequency interference generated by engines and motors, ensure stable operation of in-vehicle equipment, and avoid potential safety hazards.
-
Medical Equipment: Casings for electrocardiographs, ultrasonic instruments, and monitors
→ Dual protection: It not only prevents electromagnetic radiation from equipment from affecting human health but also avoids distortion of diagnosis and treatment data caused by external interference.
-
Aerospace: Casings for electronic components of satellites and drones
→ Cope with complex electromagnetic environments in space/high altitudes, resist strong radiation, and ensure the normal operation of precision components.
-
GB/T 18663.2: A Chinese national standard for the mechanical structure of electronic equipment, specifying the shielding design and testing methods for plastic casings.
-
GJB 2605: A military standard with higher requirements, applicable to the shielding of plastic casings for military electronic equipment.
-
Medical Field: EN 60601-1-2 (EU) and YY 0505 (China), which include shielding requirements for the electromagnetic compatibility (EMC) of medical equipment casings.
