Detailed copper foil tape

xinst3月 08, 2021

Copper foil tape is a metal tape, mainly used in electromagnetic shielding, electrical signal shielding and magnetic signal shielding.

Electrical signal shielding mainly relies on the excellent electrical conductivity of copper itself, while magnetic shielding requires the conductive material "nickel" of the copper foil tape to achieve magnetic shielding. Therefore, it is widely used in mobile phones, laptops and other digital products. in.

Classification :is divided into single-sided adhesive coating and double-sided adhesive coating.

Single-sided coated copper foil tape is 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 of copper 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 itself is also conductive on the other side. Die-cutting tape is called double-conducting that is double-sided conductive.

There are also double-sided adhesive-coated copper foil tapes that are used to process more expensive composite materials with other materials. The double-sided adhesive-coated copper foil also has two types of adhesive surfaces: conductive and non-conductive. Customers can choose according to their own needs for conductivity.

Characteristics

Copper foil has low surface oxygen characteristics and can be attached to various substrates, such as metals, insulating materials, etc., and has a wide temperature range. Mainly used in electromagnetic shielding and anti-static. The conductive copper foil is placed on the surface of the substrate and combined with the metal base material. It has excellent conductivity and provides electromagnetic shielding effect.

The purity of the copper foil tapes is higher than 99.95%, and its function is to eliminate electromagnetic (EMI) interference, isolate the harm of electromagnetic waves to the human body, and avoid unnecessary voltage and current to affect the function.

In addition, the copper foil tapes has a good effect on the static discharge after the article is grounded. It has strong adhesive force and good electrical conductivity. We can cut it into various specifications according to customer requirements. Copper foil tape has a wide range of uses.

Copper foil, conductive acrylic adhesive, good adhesion and strong adhesion.

Copper foil tape performance

It has several properties such as heat preservation, heat insulation, waterproof, good adhesion, good cold resistance, easy to tear, can eliminate electromagnetic interference (EMI), isolate the harm of electromagnetic waves to the human body, and avoid the influence of voltage or current.

Copper foil tapes is mainly used in the manufacture of computer monitors and computer peripheral wires and transformers. It is used in the joints of central air-conditioning pipelines, hoods, refrigerators, water heaters, etc. It is also used in precision electronic products, computer equipment, wires and cables. In high-frequency transmission, it can isolate electromagnetic wave interference and resist high temperature to prevent spontaneous combustion.

Generally, it is suitable for all kinds of transformers, mobile phones, computers, PDAs, PDPs, LCD monitors, notebook computers, copiers and other electronic products where electromagnetic shielding is required.
