why 100mesh copper wire mesh for EMI/RFI shielding

100-mesh copper wire mesh is a specific type of wire mesh that is constructed from high-quality copper wires, with 100 mesh openings per linear inch. It is commonly used for EMI/RFI (Electromagnetic Interference/Radio Frequency Interference) shielding applications. Here’s a description of the key features and benefits of 100-mesh copper wire mesh for EMI/RFI shielding:

  1. Material: The wire mesh is made from pure copper wires, chosen for their excellent electrical conductivity and durability. Copper is a highly effective material for EMI/RFI shielding due to its superior electrical and thermal conductivity properties.
  2. Mesh Size: The mesh size of 100-mesh wire mesh refers to the number of openings per linear inch. In this case, there are 100 mesh openings per inch, resulting in smaller openings that provide high-density coverage and effective shielding against electromagnetic interference.
  3. Shielding Effectiveness: The 100-mesh copper wire mesh offers excellent shielding effectiveness against EMI/RFI. The small mesh openings provide a barrier that attenuates and blocks electromagnetic waves, preventing interference from external sources and reducing electromagnetic emissions from the shielded area.
  4. High Conductivity: Copper is known for its high electrical conductivity, which allows for efficient dissipation of electrical and electromagnetic energy. This conductivity ensures that the mesh effectively diverts and absorbs electromagnetic energy, reducing the risk of interference and protecting sensitive electronic components or devices.
