RFI Shielding Tape

RFI Shielding Tape is a specialized solution designed to block, absorb, or redirect unwanted radio frequency signals, ensuring the smooth and reliable operation of sensitive electronics. Our high-performance RFI Shielding Tape provides a robust, flexible, and reliable barrier against disruptive radio frequency interference, safeguarding sensitive electronics and ensuring signal integrity in demanding applications.

Composition

High-Conductivity Metal Foil: The core shielding layer, typically electrodeposited copper (high conductivity, excellent flexibility) or nickel (good corrosion resistance). This layer reflects and absorbs interfering RF energy.
Conductive Pressure-Sensitive Adhesive (PSA): Specially formulated adhesive loaded with conductive particles (e.g., nickel, silver-coated copper, or carbon). This ensures low-impedance electrical contact between the foil and the surface it's applied to, creating a continuous Faraday cage effect.
Durable Carrier/Backing (Optional but Common): Often a robust polyester (PET) or polyimide film laminated to the foil for added mechanical strength, tear resistance, and ease of handling.

RFI Shielding Tape Features

High Shielding Effectiveness: Our tape achieves shielding effectiveness of up to 85 dB (decibels) across frequencies ranging from 100 MHz to 10 GHz, depending on the metal foil used. This means it blocks over 99.9% of unwanted RFI, ensuring minimal signal leakage and interference.
Excellent Conductivity: The metal foil core ensures low electrical resistance, allowing for effective grounding and the creation of a continuous Faraday cage when properly installed. This continuity is crucial for redirecting RFI away from sensitive components.
Durable and Versatile: The combination of metal foil and carrier layer makes the tape resistant to temperature extremes (-65°F to 300°F / -54°C to 149°C), chemicals, and abrasion. It performs reliably in industrial settings, outdoor environments, and enclosed electronic enclosures.
Easy to Install and Conformable: The tape is flexible and conformable, able to adhere to irregular surfaces, curves, and tight spaces. It cuts cleanly with standard tools, and its pressure-sensitive adhesive allows for quick, tool-free application—no curing time required.
Residue-Free Options: For applications where temporary shielding is needed, we offer formulations with removable adhesives that leave no sticky residue behind, making them ideal for testing, maintenance, or prototype development.

RFI Shielding Tape Applications

Electronics Enclosures & Chassis: Sealing seams, gaps, vents, and access panels in metal or plastic enclosures to prevent RF leakage (emissions) or ingress (susceptibility).
Cable Shielding & Harnessing: Repairing damaged cable shields, terminating shield braids (pigtails), bundling cables, or creating custom shielded harness wraps.
Printed Circuit Board (PCB) Shielding: Creating custom, low-profile shields over sensitive components or circuit sections; grounding shield cans.
Aerospace & Avionics: Protecting critical navigation, communication, and flight control systems from intense RF environments (both internal and external).
Military & Defense Electronics: Ensuring secure communication, radar, and weapon system functionality in EM-compromised scenarios (EMP, jamming).
Medical Devices: Shielding sensitive diagnostic equipment (MRI adjacent areas, patient monitors, implants) and ensuring compliance with strict EMC regulations.
Automotive Electronics: Protecting engine control units (ECUs), infotainment systems, ADAS sensors, and electric vehicle components from increasing in-vehicle RF noise.
Telecom & Networking Equipment: Containing emissions from servers, routers, and switches within data centers and ensuring signal integrity.
Consumer Electronics: Mitigating internal interference in high-density devices like smartphones, tablets, and wearables.
