Copper Expanded Metal Sheet With Effective EMI Shielding Performance

Electromagnetic interference (EMI) is a common problem in electronic devices and systems, which can lead to equipment performance degradation, data corruption, and communication disruption. To address this issue, copper expanded metal sheet serves as an excellent EMI shielding material that plays a role in maintaining the stability and reliability of equipment. In this article, the application of copper steel mesh in EMI shielding will be discussed in depth and elaborated from different perspectives.

Why Need EMI Shielding?

Electromagnetic interference (EMI) is caused by electromagnetic radiation that may adversely affect electronic equipment. EMI shielding blocks this interference to ensure the equipment functions properly and effectively. The importance of EMI is not only in terms of equipment performance, but also in relation to the stable operation of communications, medical equipment, and other fields.

Common Sources of EMI

• Power generation equipment and its peripherals such as generators, power supplies, voltage regulators, switches and relays, battery chargers, and high voltage transmission lines.
• Devices operating at high frequencies, such as oscillators, computing equipment, radios, radar, and sonar equipment.
• Machines operating at high voltages and frequencies, such as electric motors and ignition systems.

EMI Shielding Copper Expanded Metal Sheet

Copper expanded metal sheets stand out for their conductivity, corrosion resistance, and flexibility. Its unique design, such as the diamond-shaped hole structure, makes it an ideal EMI shielding material. The choice of copper material further enhances its suitability for EMI shielding. Expanded metal sheet shielding effectiveness (SE) is determined by material, sheet thickness, opening size (SWD × LWD), and number of openings.
