1、 Characteristics of copper tape

Die cutting copper foil tape has the characteristics of low surface oxygen, which can be attached to various substrates, such as metals, insulating materials, etc., and has a wide range of temperature applications. It is mainly used for electromagnetic shielding and anti-static. The conductive copper foil is placed on the substrate and combined with the metal substrate, which has excellent conductivity and provides electromagnetic shielding effect. The purity of copper foil tape is higher than 99.95%. Its function is to eliminate electromagnetic (EMI) interference, isolate the harm of electromagnetic wave to human body, and avoid affecting the function without voltage and current.

2、 What is copper tape?

Copper tape is a kind of metal tape, which is 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" on the adhesive surface of copper tape to achieve the role of magnetic shielding, so it is widely used in mobile phones, laptops and other digital products.
Copper foil adhesive tape is divided into single-sided adhesive tape and double-sided adhesive tape. The copper foil tape with one side covered with adhesive can be divided into single conductive copper foil tape and double conductive copper foil tape. The single conductive copper foil tape means that the adhesive coated side is not conductive, and only the other side is conductive, so it is called single conductive copper foil tape; Double conductive copper foil tape refers to that the adhesive coated surface conducts electricity, and the copper on the other side also conducts electricity, so it is called double conductive, i.e. double conductive. In addition, double-sided adhesive coated copper foil tape is used to process expensive composite materials with other materials. The adhesive surface of double-sided adhesive coated copper foil can also be divided into conductive and non-conductive. Customers can choose according to their own conductive needs.

3、 What can copper tape be used in?

It is generally applicable to various transformers, mobile phones, computers, PDAs, PDP, LCD displays, laptops, copiers and other electronic products where electromagnetic shielding is required.
I. Use of LCD: Manufacturers and communication markets usually use copper foil to paste electronic products, including LCD TVs, computer monitors, tablets, digital products, etc., mainly to eliminate electromagnetic interference and ensure the normal use of products.

II. Use of mobile phone maintenance shield: Because copper foil tape has the characteristics of electrical signal shielding and magnetic signal shielding, some common communication tools should not be used in specific occasions. After special treatment, they can be carried into special occasions.

III. Use of punching chips: large factory workshops usually use copper sheet materials to make products, and use copper foil tape die-cutting to make chips for production, which not only greatly improves production efficiency and reduces production costs, but also is economical and practical.

IV. Wide range of electronic and electrical digital applications: copper foil tape is used for pipeline joints of central air conditioning pipelines, cigarette smoking machines, refrigerators, water heaters, etc. It is also suitable for precise electronic products, computer equipment, wires and cables, etc. During high-frequency transmission, it can isolate electromagnetic wave interference, withstand high temperature, thus preventing spontaneous combustion, and is used in mobile phones, laptops, electronic appliances and other digital products, Therefore, copper foil tape is widely used.

Shenzhen Xinst Technology Co., Ltd. is a company specialized in die cutting and processing various adhesive products of special electronic insulation accessories. Copper tape is one of the main products of the company, with strong temperature resistance and isolation of radio interference.

Common sense of application of copper tape

I. The test conditions are normal temperature 25 ℃, and the relative humidity below 65 ℃. The test results of ASTM D-1000 are used;
II. Please keep the room dry and ventilated when storing the goods,
III. The product is mainly used to eliminate electromagnetic interference EMI and isolate the harm of electromagnetic wave to human body. High temperature tape is mainly used in the manufacturers of wire materials around computers, computer monitors and transformers.
