What is copper foil tape?
Copper foil tape is a metal tape, EMI shielding copper foil tape mainly used for electromagnetic shielding, electrical signal shielding and magnetic signal shielding.
EMI shielding copper foil tape mainly depends on the excellent electrical conductivity of copper itself, while magnetic shielding requires the conductive material "nickel" of the copper foil tape to achieve the role of magnetic shielding, so it is widely used in mobile phones, notebook computers and other digital products in.
Classification of copper foil tape
Copper foil tape is divided into single-sided adhesive and double-sided adhesive
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 non-conductive, and only the other side is conductive. ; Double-conducting copper foil tape 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.
There are also double-sided coated copper foil tape used to process into more expensive composite materials with other materials. The double-sided coated copper foil has conductive and non-conductive surfaces. Customers can choose according to their needs for electrical conductivity.
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, which has excellent conductivity and provides the effect of electromagnetic shielding.
The purity of the copper foil tape 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 unnecessary voltage and current to affect the function.
In addition, copper foil tape has a good effect on the static discharge after the article is grounded. Its strong adhesion and good electrical conductivity, we can cut to various specifications according to customer requirements. Copper foil tape is very versatile.
Copper foil tape substrate
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 tape is mainly used in the manufacture of computer monitors, computer peripheral wires and transformers. It is used in the joints of pipelines for central air conditioning pipelines, smoke machines, refrigerators, water heaters, etc., and is 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.
Copper foil tape use
Generally applicable to all kinds of transformers, mobile phones, computers, PDA, PDP, LCD monitors, notebook computers, copiers and other electronic products where electromagnetic shielding is required.
