Shielding-Copper wire mesh has shielding electromagnetic characteristics

Copper wire mesh can provide effective electromagnetic shielding

When ventilation, light transmission, water addition, measurement, etc. are required, holes should be made on the equipment shell. In order to improve the electromagnetic shielding effect of the equipment, copper wire mesh should be used for shielding. Or used in the joints of electronic equipment shells to provide effective electromagnetic shielding. The shielding effectiveness of holes SE (dB) is related to the frequency of electromagnetic waves, the size and number of holes and other parameters.

Copper wire mesh

In order to improve the shielding effect of the hole, the following measures can be taken:

1) Cover the large-diameter holes with copper wire mesh, so that the copper wire mesh is in good contact with the shielding body;

2) Change the big hole to small hole;

3) Adopt waveguide attenuator type vent;

4) Transparent shielding glass covered with copper wire mesh on the measuring hole;

5) Put a piece of copper wire mesh containing rubber and other materials on the hole that needs to be sealed by water and air.
