Description

Technical Field

[0001] The utility model relates to the technical field of electronic products, in particular to a shielding cover. Background Art

[0002] The core component of electronic products is the motherboard, which houses numerous devices. Each device radiates electromagnetic waves when in operation. Devices with significant electromagnetic interference require shielding. To prevent external electric, magnetic, or electromagnetic fields from interfering with internal devices, or to prevent the device's electromagnetic field from affecting the outside world, the device is enclosed in a closed or nearly closed metal shell or metal mesh enclosure, called a shield. The shield's function is to shield the internal circuitry from external electromagnetic waves and to shield the internally generated electromagnetic waves from radiating outward. It is typically made of 0.2mm thick nickel silver (a metal that readily tins) and is attached to the motherboard using solder paste. However, existing shields are complex in structure, leaving room for improvement in electromagnetic shielding effectiveness and heat dissipation performance. They also present certain issues with installation and stability. Utility Model Content
