Advanced Solutions in Metal EMI Shielding Products

Understanding Metal EMI Shielding

The Role of EMI Shielding

EMI shielding is critical for ensuring that electronic devices operate without interference from electromagnetic noise. This noise can originate from various sources, both internal and external to the device. Effective EMI shielding solutions help in maintaining functionality and reliability, particularly in sensitive environments like medical facilities or aerospace applications.

Common Materials and Technologies

• Ferrites: Often used in cabling to diminish high-frequency interference.
• Silicone and Fluorosilicone: Popular for their flexibility and environmental resistance, making them ideal for seals and gaskets.
• EPDM (Ethylene Propylene Diene Monomer): A durable synthetic rubber used extensively in sealing applications due to its resistance to weathering, ozone, and heat.
• Beryllium Copper: Known for its high tensile strength and excellent electrical conductivity, making it suitable for a broad range of shielding applications.
