Copper foil tape is widely used in the fields of electronics, communication, electromagnetic compatibility (EMC) and new energy because of its excellent electrical conductivity, shielding effect and thermal conductivity.
Electromagnetic Shielding and Anti-Interference
โšก Electronic Equipment Shielding

Used for internal shielding of electronic products such as mobile phones, notebook computers, tablet computers, GPS navigators, etc., to wrap the motherboard, cable or specific components to prevent electromagnetic wave leakage or external interference.

๐Ÿ“ก Communication Equipment

Used to shield cavities and connection gaps in communication equipment such as base station antennas, routers and set-top boxes to ensure stable signal transmission.

Circuit Conduction and Grounding
๐Ÿ”Œ Circuit Board (PCB) Patching

In PCB manufacturing or maintenance, it is used to repair broken circuit lines and realize temporary or permanent conduction instead of welding.

๐Ÿ’ป Flexible Circuit Board (FPC)

Used for conductive connection, lead-out or as a part of the circuit of FPC.

๐Ÿ”Œ Electrical Grounding

Used for grounding the metal shell of household appliances and office equipment to prevent static electricity accumulation or leakage.

Lithium Battery Manufacturing (New Energy)
๐Ÿ”‹ Battery Cell Connection

Used for the connection between the tab and the protection plate or the parallel/series conductive connection between batteries in the PACK process of lithium batteries (such as power batteries and energy storage batteries).

โšก Busbar

Replacing part of metal bus bar, used for current collection and transmission in battery module.

Transformer and Motor Manufacturing
๐Ÿ”„ Transformer Winding

Used for winding production of high-frequency transformers and pulse transformers, and the winding density is improved by using its thin characteristics.

โš™๏ธ Motor Commutator

In some micro-motors, it is used to connect the conductive strips of the commutator.

Heat Dissipation and Heat Conduction
๐Ÿ’ก LED Lighting

Used for the heat conduction connection between the high-power LED lamp beads and the heat dissipation aluminum substrate, which helps to conduct heat quickly.

๐Ÿ’ป Power Device

Used for auxiliary heat dissipation of heating elements such as CPU, graphics card chip and power module.

Family Gardening and Potted Plant Protection

๐ŸŒฟ Protection of Potted Plants: This is the most common application scenario. Stick the copper foil adhesive tape around the edge of the pot mouth or the middle and upper part of the outside of the pot wall. When snails try to climb into the feeding leaves along the basin wall, they will feel uncomfortable when they touch the copper belt, thus protecting potted flowers, herbs and vegetables indoors and outdoors.

Other Industrial Applications
๐Ÿ”Œ Electromagnetic Induction

Used for making induction coil of induction cooker panel, or as trigger element of induction switch.

๐Ÿ›๏ธ Architecture and Decoration

Used for metal decorative lines in high-grade decoration, edge sealing of furniture or as conductive tape for floor heating system.

Frequently Asked Questions (FAQ)
Q1 What is the difference between single-sided and double-sided conductive copper foil tape?
Single-sided conductive copper foil tape (e.g., HY500-1 to HY500-4) has adhesive on one side only, making it ideal for surface attachment and standard EMI shielding. Double-sided conductive tape (e.g., HY500-5 to HY500-9) has conductive adhesive on both sides, enabling electrical connection through the tape itself โ€” commonly used in battery packs and grounding applications where both surfaces must conduct.
Q2 What type of adhesive is used on these copper foil tapes?
All models in the HY500 series use an oily acrylic adhesive. This type of glue offers strong initial tack, excellent long-term adhesion, good temperature resistance, and reliable performance in both indoor and outdoor environments.
Q3 Is the HY500-3 copper foil tape equivalent to 3M 1181?
Yes. The HY500-3 model (0.035mm film thickness, 0.07mm total thickness) is listed as equivalent to 3M 1181, making it a cost-effective alternative for applications that specify 3M 1181 copper foil tape, such as EMI shielding in electronics manufacturing.
Q4 Can copper foil tape be used for PCB repair?
Yes. Copper foil tape is commonly used in PCB repair to bridge broken traces or create temporary conductive paths. Its thin profile and strong adhesion allow precise application on circuit boards without soldering, making it a practical solution for both prototyping and field repairs.
Q5 How does copper foil tape protect potted plants from snails?
When a snail or slug attempts to cross copper foil tape, a mild electrochemical reaction occurs between the copper and the moisture in the pest's body, creating a sensation that deters them from crossing. Wrapping the tape around the rim or outer wall of a pot creates an effective, chemical-free barrier to protect plants.
Q6 What thicknesses are available and how do I choose the right one?
The HY500 series offers film thicknesses ranging from 0.015mm to 0.090mm, with total thicknesses from 0.05mm to 0.2mm. For tight-space applications like FPC or high-frequency transformers, thinner options (HY500-1, HY500-2) are recommended. For higher current applications such as battery busbars or power modules, thicker options (HY500-5, HY500-8, HY500-9) provide better conductivity and mechanical strength.
