Copper Foil Tape/ Conductive Copper Foil/ Foil Copper Sticker Price | Supplier & Manufacturer

Shanghai Metal Corporation is a leading Copper Foil Tape/ Conductive Copper Foil/ Foil Copper Sticker manufacturer and supplier.

Copper foil tape consists of thin copper foil backed by conductive pressure-sensitive adhesive, available in single-sided and double-sided conductive versions. It is applied in electronic prototyping, electromagnetic shielding, equipment grounding and minor maintenance tasks. Engineers use it to build temporary circuit traces, wrap signal cables and device housings, and set up static discharge paths. This tape mainly solves electromagnetic interference that distorts electronic signals and generates noise. It provides low-resistance grounding to drain static electricity and protect sensitive components. Its flexible foil conforms to curved or uneven surfaces, enabling quick conductive connections without welding for both temporary and permanent assembly work.

1. Types: single-sided & double-sided.

2. Thickness: 0.018mm - 1.2mm.

3. Width: 5mm - 500mm.

4. Operating temperature range: -20 ℃ to 120 ℃.

5. Elongation at break: 8% minimum.

1.Stable Conductive Performance: Maintains consistent conductivity after repeated bending and slight stretching, helping sustain stable signal transmission and reliable grounding for electronic assemblies.

2. Good Conformability: Can closely attach to curved, angular and irregular substrate surfaces, helping avoid shielding gaps that may cause electromagnetic leakage.

3. Low Residue Adhesive Property: Leaves minimal adhesive residue upon removal within the service temperature range, helping save cleanup time and prevent contamination on finished components.

4. Wide Temperature Adaptability: Retains adhesion and shielding capability across the rated working temperature range, supporting stable use in both indoor and enclosed electronic equipment environments.

5. Easy Manual Tearability: Allows manual tearing without cutting tools during on-site installation, helping shorten assembly time and improve operation efficiency for prototype and repair work.

1.EMI Shielding for Internal PCB Cables: Used to wrap signal wires inside monitors and power adapters. Copper foil tape blocks stray electromagnetic radiation, avoiding signal interference between adjacent circuit boards.

2. Static Grounding for Electronic Enclosures: Applied to metal and plastic equipment housings to build grounding paths. It conducts accumulated static charge to ground, protecting sensitive semiconductors from electrostatic damage.

3. RF Shielding for Antenna Cavities: Lined inside communication module shell cavities to contain radio frequency signals. Its continuous conductive layer prevents RF signal leakage and improves antenna stability.

4.Temporary Circuit Traces for Electronics Prototyping Stuck on substrate boards to build test circuits during R&D verification. It forms quick conductive paths without soldering, supporting fast modification of prototype designs.

5. Heat Conduction for Small Power Components Attached to low-power chips to assist heat spreading. Copper’s high thermal conductivity disperses local hot spots and reduces component operating temperature.

Q1: What information do you need for a custom quotation of copper foil tape?

A: Required details include foil thickness, adhesive type, roll width/length, order quantity, destination port and special certification requirements.

Q2: What quality standards does your copper foil tape comply with?

A: It follows RoHS for hazardous substance restriction and IPC standards for electromagnetic shielding and conductive performance testing.

Q3: What storage conditions are recommended for copper foil tape?

A: Store in dry space at 15–25°C, avoid direct sunlight and high humidity; keep away from strong acid and alkali environments.

Q4: How does copper foil tape reduce EMI interference on PCB signal cables?

A: It forms a continuous conductive shield layer to reflect and absorb electromagnetic radiation, then diverts noise to ground via conductive adhesive.

Q5: Can copper foil tape maintain stable conductivity after repeated bending in antenna cavity applications?

A: Single-sided copper foil tape may crack after frequent bending; double-sided conductive grade retains better conductivity under cyclic bending.

Q6: What is the maximum continuous operating temperature for grounding use on electronic enclosures?

A: The rated continuous working temperature is -20°C to 120°C, beyond which adhesive will degrade and conductivity drops.
