Red Copper Mesh

Copper mesh for EMI shielding is designed for applications that require both electromagnetic interference control and an open mesh structure for ventilation, visibility, flexibility or weight reduction. Compared with solid metal shielding, woven copper mesh is better suited to electronic enclosures, shielded windows, Faraday cages, ventilation openings and RF-sensitive equipment where a fully closed metal sheet cannot be used.

The main performance of an EMI shielding mesh is determined by the combination of electrical conductivity, mesh count, wire diameter, aperture size and installation continuity.
