Electromagnetic Interference (EMI) shielding is a measure within an area of space to attenuate field strengths caused by certain sources. In most cases, the shield can be made of metals such as expanded copper mesh, aluminum expanded mesh, etc., but for constant and very low frequency magnetic fields, materials such as ferrite can also be used as shields.

The electromagnetic shielding machine room assembled with copper expanded sheet is light weight, fast installation, reliable in electromagnetic sealing, strong in assembly and disassembly process, and at the same time,it meets the needs of ventilation and lighting.

The biggest advantage of electromagnetic shielding machine room assembled with expanded copper mesh is the low cost.

Widely application of expanded copper sheet for EMI shielding:

communication products (mobile phones),
computers (notebooks),
portable electronic products,
consumer electronics,
network hardware (servers, etc.),
medical instruments, h
ousehold electronic products
electronic equipment such as aerospace and defense
