RFI Shielding Copper Foil Tape

RFI Shielding Copper Foil Tape is a specialized tape designed to provide effective protection against radio frequency interference (RFI). The working principle of RFI shielding copper foil tape: utilizing the high conductivity of copper, when electromagnetic wave is incident to the copper foil tape, it will generate an induced current on the surface of the copper foil, thus consuming and reflecting the electromagnetic wave, and playing the role of shielding RFI. For magnetic signal shielding, it mainly relies on the conductive substance “nickel” on the adhesive surface. It is widely used in electronics, telecommunications and industrial applications to shield sensitive components and equipment from electromagnetic interference (EMI) and RFI.

Base Material: High-quality copper foil, known for its excellent electrical conductivity and flexibility.
Adhesive: Conductive adhesive (typically acrylic or rubber-based) that ensures a strong bond and continuous electrical conductivity.

RFI Shielding Copper Foil Tape Features

Shielding Performance: Provides RFI and EMI shielding, reducing interference from external radio frequencies and electromagnetic waves.
Surface Resistance: Typically ranges from 0.01 to 0.1 ohms per square, ensuring efficient grounding and shielding.
Durability: Resistant to moisture, corrosion, and oxidation, making it suitable for harsh environments.
Heat resistance: Can withstand a wide temperature range (e.g., -40°C to 120°C), depending on the adhesive type.
Flexibility: Thin and flexible, allowing it to conform to irregular surfaces and tight spaces. Easy to cut, shape, and apply.
Strong adhesion: the adhesive of the tape can ensure firm adhesion with the surface of the object, and it is not easy to fall off in the long term to ensure the stability of the shielding effect.
