The most commonly used in our daily life is scotch tape, which is used to seal some boxes, bags, etc., to achieve a sealing effect. Copper foil tape is rarely used, but it is essential. So what is copper foil tape? In what ways can it be used? Let’s take a look together!

1. What is copper foil tape?

Copper foil tape is a kind of metal tape, mainly used in electromagnetic shielding, electrical signal shielding and magnetic signal shielding. Electrical signal shielding mainly relies on the excellent conductivity of copper itself, while magnetic shielding requires copper foil tape. Surface conductive material “nickel” to achieve the effect of magnetic shielding, so it is widely used in mobile phones, notebook computers and other digital products.

Copper foil tape is divided into single-sided adhesive coating and double-sided adhesive coating. Single-sided coated copper foil tapes are divided into single-conductor copper foil tape and double-conductor copper foil tape. Single-conductor copper foil tape means that the coated surface is not conductive, and only the other side is conductive, so it is called single-conductor means single-sided conductive ; Double-conducting copper foil tape means that the rubber-coated surface is conductive, and the copper on the other side is also conductive, so it is called double-conducting that is double-sided conduction. There are also double-sided adhesive-coated copper foil tapes that can be processed with other materials into more expensive composite materials. The double-sided adhesive-coated copper foil also has two types of adhesive surfaces: conductive and non-conductive. Customers can according to their own needs for conductivity To choose.

2. In what areas can copper foil tape be used?

1. Use of liquid crystal display: Manufacturers and communication markets usually use copper foil to paste electronic products, including LCD TVs, computer monitors, tablet computers, digital products, etc., mainly to eliminate electromagnetic interference and ensure normal use of products.

2. Mobile phone repair and shielding use: Because the copper foil tape has the characteristics of electrical signal shielding and magnetic signal shielding, some commonly used communication tools are not suitable for use in special occasions. After special treatment, they can be carried into special occasions.

3. The use of punching slices: large-scale factory workshops usually use copper sheet materials to manufacture products, and use copper foil tape die-cutting to make slices and apply them to production. This will greatly improve production efficiency and reduce production costs, which is economical and practical.

4. Digital electronic appliances are widely used: copper foil tape is used in the joints of central air-conditioning pipelines, hoods, refrigerators, water heaters, etc. It is also suitable for high-frequency transmission in precision electronic products, computer equipment, wires and cables, etc. It can isolate electromagnetic wave interference, resist high temperature and prevent spontaneous combustion. It is used in mobile phones, notebook computers, electronic appliances and other digital products. Therefore, the use of copper foil tape is still very extensive.
