Product Name
Bron BT-7A Performance Grade Copper Foil Tape - 2in x 36yds
Brief Description
The Bron BT-7A Performance Grade Copper Foil Tape is a self-adhesive metal tape made from thin sheets of copper, coated with an adhesive. It is specifically designed for applications requiring superior electrical conductivity, electromagnetic shielding (EMI/RFI), grounding, and conformability. This tape is known for its good temperature resistance and is ideal for critical shielding and masking tasks.
Popular Applications & Uses
- Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI) shielding for electronic devices and circuit boards.- Grounding and electrostatic discharge (ESD) protection in sensitive electronic components and manufacturing facilities.- Repair and modification of printed wiring boards (PWBs).- Shielding of joints and cables to prevent signal degradation.- Electrical signal shielding due to copper's excellent conductivity.- Heat transfer applications to improve cooling efficiency in electronic devices.- Insulation of wires, cables, and pipes from heat, cold, moisture, and abrasion.- HVAC industry for sealing and insulation purposes, and repairing damaged ducts.- Automotive industry for shielding, grounding, and electrical conductivity.
Industries that Commonly Use It
- Electrical Services or Products- LED/Electronics- Automotive Service/Repair- Construction/ Building Services (for HVAC and general building applications)- General Manufacturing- Aerospace/Defense (for critical shielding and masking)- Engineering Services (for prototyping and design troubleshooting)- Metal Fabrication
Special and Unique Features
- Performance grade copper foil tape.- Good temperature resistance.- Excellent conformability, allowing it to adhere to irregular surfaces.- Provides both electrical and thermal conductivity.- Effective for both electrical signal shielding and magnetic signal shielding.- Durable performance.
Key Properties
- Material: Copper foil.- Adhesive: Pressure-sensitive acrylic adhesive, often conductive.- Electrical Conductivity: Excellent, second only to silver.- Thermal Conductivity: High, enabling quick heat transfer.- Corrosion Resistance: Copper is resistant to corrosion, enhancing durability.- Shielding Effectiveness: Reliably blocks both magnetic and electrical waves.- Dimensions: 2 inches width x 36 yards length.
Surface Compatibility
The aggressive adhesive provides a quick stick to various surfaces, including insulation surfaces, printed wiring boards, and other electronic components. It conforms well to irregular surfaces.
Known backups / known substitutes
- **Aluminum Foil Tape:** Offers excellent electrical performance and shielding characteristics, often more cost-effective than copper.- **Tinned Copper Foil Tape:** Similar electrical properties to copper foil but with enhanced resistance to humidity and extreme temperatures, and less prone to oxidation.- **Slug and Snail Barrier Tape (non-conductive adhesive copper foil tape):** Can be a low-cost alternative for EMI tape in some situations, though its adhesive may not be conductive.- **Silver Coated Copper Tape:** More resistant to tarnishing and oxidation, with slightly better conductivity in some cases.
Comparison Note
While aluminum foil tape is a more economical alternative, copper foil tape like the Bron BT-7A offers superior electrical conductivity and robust shielding against both magnetic and electrical waves, making it a preferred choice for critical electronic and EMI/RFI sensitive applications. Tinned copper foil tape provides similar electrical properties to copper but with improved durability in harsh environments due to its resistance to oxidation.
