Key Product Snapshot
First-round engineering and sourcing data moved forward for faster product-fit judgment.
Product Overview
Copper foil tape is a conductive tape used for EMI shielding, grounding continuity and electrical repair. It is suitable for enclosure seams, cable and connector areas, PCB work and custom converted shielding parts, with supply available in slit rolls, sheets and die-cut formats for industrial assembly and maintenance use.
Key Advantages
Short, value-based statements for engineering review and procurement communication.
Reliable EMI Control
Supports conductive shielding across seams, housings and connector zones where interference control matters.
Stable Electrical Path
Helps build grounding and bonding paths for discharge, continuity and conductive connection needs.
Flexible for Conforming Areas
Foil structure adapts to flat and slightly contoured surfaces for wrapping, overlap and localized repair work.
Conversion-Friendly Supply
Available in slit roll, sheet and die-cut formats for sample verification and repeat production use.
Typical Applications
One integrated application visual anchors the module, while the cards on the right keep engineering and sourcing information easy to scan.
EMI Shielding for Enclosures
Used on seams, joints and contact areas where conductive overlap helps improve shielding continuity.
Grounding and Bonding
Applied to create conductive grounding paths between parts, housings and electrical connection points.
PCB Repair and Prototyping
Useful for temporary conductive repair, trace bridging and evaluation work in electronics development.
Cable and Connector Wrapping
Supports wrapping and conductive contact in cable assemblies, connector zones and harness shielding details.
Charge Dissipation Design
Suitable for conductive contact points where static discharge or continuity control is required.
Custom Die-Cut Shielding Parts
Can be converted into repeatable shapes for device interiors, modules and production-side shielding layouts.

FAQ
Clear, static FAQ styling with no dark bars, no hover motion and no visual distraction.
Can copper foil tape be supplied with conductive and non-conductive adhesive?
Yes. Copper foil tape can be supplied with conductive acrylic adhesive or non-conductive pressure-sensitive adhesive, depending on whether your project requires electrical continuity through the adhesive layer.
Is this tape suitable for EMI shielding applications?
Yes. It is commonly used for EMI shielding on enclosure seams, cable areas, connector zones and conductive overlap points where shielding continuity is required.
Can you provide slit rolls or die-cut parts instead of standard rolls?
Yes. We can support master log rolls, custom slit widths, sheets and converted die-cut parts based on drawing, sample or dimensional requirement.
What thickness range is commonly available?
The typical total thickness range on this page is 0.05–0.15 mm. The final structure should still be confirmed by adhesive system, foil thickness and end-use requirement.
Can I request samples before mass production?
Yes. Sample rolls or converted sample pieces can be arranged for product-fit review, assembly check and preliminary testing before bulk order confirmation.
What information should I send for faster recommendation or quotation?
Please share the application, substrate, required conductivity path, thickness preference, width or part size, temperature condition and whether you need roll supply or die-cut conversion.
