Introduction to metal EMI lining materials in electromagnetic shielding materials

These varieties include braided wire mesh, wire mesh wrapped on an elastomer core, directional wire in an elastomer, and wire screens, which typically provide 60dB-100dB of attenuation in the 20MHz-1GHz range. It can be fixed in the groove of the box by conductive adhesive or mechanically.
It can also be directionally embedded in silicone by Monel or aluminum wire, which not only provides EMI shielding, but can also be used for rainwater, water leakage, dust and ventilation sealing, with a temperature range of -55°C - +260°C.
The clip-on EMI lining is made of carbon-filled silicone strips or Monel wire on the silicone tape or Ferrex wire on the neoprene to provide EMI shielding. The lining is fixed on an anti-corrosion stainless steel spring clip, which is easy to install. . No holes or fasteners required.
Beryllium copper reeds are finger-shaped reeds made of special alloy beryllium copper, which combine high-level EMI shielding effects and elastic hook friction with small closing force characteristics. The high-performance parameters of beryllium copper: high tensile strength, good anti-corrosion properties and good electrical conductivity make it an ideal EMI shielding material for use in a wide frequency band and can be used in a wide range of electronics where EMI/RFI or ESD problems exist. in the device. There are different finished products of bright copper, bright nickel, and bright tin, which are installed on different metal surfaces to reduce galvanic noise and electrical corrosion between different metals.
Spira metal spiral pipes can be installed in grooves, and the metal pipes can also be filled with rubber or silicone cores.
