Understanding The Role Of Copper Mesh In RFI Shielding

Copper mesh is known for its widespread applications in filtration, interior decor, rodent screens and more. Apart from this, the copper wire mesh is also used for another critical application, such as an RFI shielding screen. But what exactly is RFI shielding, why is it necessary and how does copper mesh contribute to the process? In this blog, Ferrier Wire aims to address these questions in detail.

What Is RFI Shielding?

To understand RFI shielding, it is first important to comprehend electromagnetic interference (EMI). EMI is a strong signal or energy that can potentially harm complex machinery and can even be damaging to human beings. Therefore, there is a need to shield the machines from EMI. This method of protecting machines and technology from electromagnetic interference is defined as RFI shielding.

This method is used to protect a wide variety of modern devices such as portable computers, smart meters, stealth technology, sensitive military technology, telecommunication systems, medical equipment like MRI machines and more. 

Why Use Copper Mesh For RFI Shielding?

Copper weave mesh is ideal for achieving effective RFI shielding due to the following features:

- Excellent thermal conductivity: Copper is known for its high thermal conductivity, ensuring the RFI shield/Farraday cage doesn’t get overheated.

- Exceptional electrical conductivity: This wire mesh also has high electrical conductivity, which is extremely critical for RFI shielding.

- High air flow: Ferrier Wire offers quality copper mesh with a high open area ranging from 44.2 percent to 67.9 percent.

Hence, a copper mesh is great for shielding machines and technology from harmful electromagnetic interference.
