Description
Atomfair Copper Foil Tape – International Product Specification
Product Overview
Atomfair Copper Foil Tape is available in two main variants: Single-Conductor and Double-Conductor. Crafted by precision combining high-purity copper foil with premium adhesive layers, it delivers exceptional electrical conductivity, electromagnetic shielding performance, and bonding strength. This product is widely tailored to meet the EMI shielding and conductivity requirements of various consumer electronic devices, complying with international standards including RoHS and REACH.
Product Classification
1. Single-Conductor Copper Foil Tape
Features a non-conductive adhesive layer on one side and an exposed copper surface on the other. Only the copper surface exhibits conductive properties, making it ideal for single-sided conductivity applications such as basic EMI shielding in simple electronic assemblies.
2. Double-Conductor Copper Foil Tape
Equipped with a conductive adhesive layer on one side. Both the copper foil surface and the adhesive layer possess conductive capabilities, suitable for complex application scenarios requiring dual-sided conductivity, including high-performance electronic shielding systems.
Product Construction & Performance
The product consists of three key components: a high-purity copper foil layer, single-sided insulating paper, and a middle layer of imported pressure-sensitive acrylic adhesive. Its core performance characteristics include:
- Superior Adhesion: Imported pressure-sensitive adhesive ensures strong and durable bonding to various substrates (plastic, metal, glass) commonly used in electronics.
- Excellent Ductility: Facilitates easy shaping and application on curved or irregular surfaces without cracking.
- High Conductivity: Premium copper foil guarantees efficient electrical transmission and static discharge.
- Enhanced Shielding: Nickel-plated surface significantly boosts electromagnetic interference (EMI) shielding effectiveness, ensuring stable device operation by blocking harmful electromagnetic waves.
Core Advantages
- High-Purity Material: Copper foil purity exceeds 99.95%, laying a solid foundation for outstanding electrical conductivity and shielding performance, in line with ASTM B152/B152M standards.
- Superior EMI Shielding: Effectively eliminates electromagnetic interference, blocks harmful radiation, and prevents stray current and voltage disruption, meeting CISPR 22 EMI shielding requirements.
- Static Discharge Protection: Conducts static charges to the ground, minimizing the risk of electrostatic damage to sensitive electronic components.
- Strong & Reliable Adhesion: Imported pressure-sensitive adhesive maintains stable bonding even in harsh operating environments, with excellent temperature resistance.
- Flexible Customization: Can be cut into various widths and lengths according to customer specifications, adapting to diverse production needs.
Application Fields
Widely used in a broad range of electronic and consumer products, including:
- Transformers and inductors
- Mobile phones, tablets, and PDAs
- Desktop computers, laptops, and printers
- Plasma Display Panels (PDP) and Liquid Crystal Displays (LCD)
- Automotive electronics and medical devices

Additional Technical Parameters
- Operating Temperature: Up to 100?C (212?F), suitable for most electronic device operating environments.
- Elongation: Standard elongation is approximately 5%; customizable according to specific customer requirements (tested per ASTM D882).
- Shelf Life: 12 months under recommended storage conditions.
Usage & Storage Instructions
Usage Notes
- Ensure the bonding surface is clean, dry, and free of dust, oil, or other impurities before application for optimal adhesion.
- Avoid repeated peeling and reapplication, as this may reduce bonding strength and conductivity.
- Apply uniform pressure after bonding to ensure full contact between the tape and the substrate.
Storage Conditions
- Store in a cool, dry environment at room temperature (15-25?C / 59-77?F) with relative humidity below 65%.
- Avoid direct sunlight, high temperature, and moisture to prevent adhesive degradation.
- Keep the product in its original packaging until use to protect the copper surface and adhesive layer.
