Die-cutting materials | Detailed explanation of copper foil tape!

xinst5月 11, 2020

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

Electrical signal shielding mainly depends on the excellent conductivity of copper itself, while magnetic shielding requires the conductive material "nickel" of the copper foil to achieve the role of magnetic shielding, and is therefore widely used in mobile phones, notebook computers and other digital products in.

Classification of copper foil: Copper foil is divided into single-sided adhesive and double-sided adhesive.

The single-sided coated copper foil tape is divided into single-conductor copper foil tape and double-conductor copper foil tape. Single-conductor copper foil means that the coated surface is non-conductive, and only the other side is copper conductive, so it is called single-conductor that is single-sided conductive ; Double-conducting copper foil means that the rubber-coated surface is conductive, and the copper on the other side is also conductive. Die-cutting tape is called double-conducting, that is, double-sided conductive.

 

Characteristics of copper foil tape

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

The purity of the copper foil is higher than 99.95%, and its function is to eliminate electromagnetic interference (EMI), isolate the electromagnetic waves from harming the human body, and avoid affecting the function without the need of voltage and current.

In addition, It has a good effect on the static discharge after the article is grounded. Its strong adhesive force and good electrical conductivity, we can cut into various specifications according to customer requirements. Copper foil tape is very versatile.

 

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.

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

application:

Generally applicable to all kinds of electronic products such as transformers, mobile phones, computers, PDAs, PDPs, LCD monitors, notebook computers, copiers, etc. where electromagnetic shielding is required.
