1>. Why to choose copper wire mesh?
Answer: Because the conductivity of copper mesh is good, and copper mesh (red copper mesh) is more copper content and good conductivity, so copper mesh is suitable for shielding. Of course, gold and silver have better conductivity than copper, but they are not suitable for shielding because the cost is too high.
2>. Why should the shield use a brass mesh with good conductivity?
Answer: The metal mesh cuts the magnetic induction line movement to the electromagnetic field to produce a weak current, so the better the conductivity and shielding efficiency.
3>. Summary: Copper mesh wire has good performance and cuts the magnetic induction line movement for the electromagnetic field
The second point: the shielding effect of the copper mesh is related to the conductivity and the mesh of the copper mesh.
A: The conductivity of pure copper mesh is unquestionable. Theoretical research: brass wire mesh can be shielded with less than a quarter of the wavelength. 60 mesh-100 mesh is a commonly used shielding mesh specification, copper mesh good shielding effect is 200 mesh, but generally we use less than 200 purposes in our daily life Because its wire diameter after 0.05mm mesh is only 0.077mm, the fine is like a bed sheet at home.
