Copper foil tape is a metal tape, mainly used in electromagnetic shielding, signal shielding and magnetic signal shielding two kinds, electrical signal shielding mainly rely on copper itself excellent conductivity, and magnetic shielding requires copper foil adhesive tape conductive material "nickel" to achieve the role of magnetic shielding, and thus is widely used in mobile phones, notebook computers and other digital products.
Copper foil tape is divided into single-sided adhesive and double-sided plastic. One-sided adhesive tape is divided into single copper foil tape and dual-guide copper foil tape, Copper Foil Adhesive Tape single-lead copper foil tape that refers to the adhesive surface is not conductive, only the other side of the copper conduction, it is said that Tan Yi is one-sided conduction; dual-guide Copper foil tape refers to the adhesive surface conductive, and the other side of the copper itself is conductive, it is said that two-sided conduction. Copper Foil Adhesive Tape There are double-sided adhesive tape used in copper foil and other materials processed into a more expensive composite material, double-sided adhesive copper foil is also divided into conductive and non-conductive. Customers can choose according to their own demand for electricity.
Copper foil with low surface oxygen characteristics, can be attached with a variety of different substrates, such as metal, insulating materials, etc., with a wide range of temperature. Copper Foil Adhesive Tape Mainly used in electromagnetic shielding and anti-static, conductive copper foil placed on the substrate, combined with metal substrate, has excellent guidance, and provide electromagnetic shielding effect.
Copper foil tape, from top to bottom in turn with a printing pet layer, ink layer, composite rubber layer, nickel mesh layer, copper foil layer, pressure sensitive adhesive layer and the film layer, wherein, the copper foil layer near the pressure sensitive adhesive layer is provided with a honeycomb-shaped groove. In this case, the use of printing-grade pet as an outer material, not only to ensure the appearance of the product brightness, but also make the ink easy to coating, thereby improving the distribution uniformity of the ink, the use of low surface oxidation characteristics of copper foil, and in its proximity to the pressure-sensitive adhesive on the side of the honeycomb-shaped groove to increase the contact surface area, On the basis of ensuring electromagnetic shielding effect of products, further improve the adhesion of copper foil and pressure-sensitive adhesive layer, Copper Foil Adhesive Tape to ensure the stability of the product structure; by adding honeycomb-shaped nickel mesh to increase the magnetic shielding capacity of products, while honeycomb-like structure can be adhesive adhesives through the nickel network and copper foil bonding, Copper Foil Adhesive Tape to ensure that the composite layer, The bonding stability of nickel mesh layer and copper foil layer.
Copper Foil Tape Series Classification:
1. Pure copper foil has conductive, mask function;
2. Single-conductivity copper foil conductive, mask (rubber surface non-conductive), coated acrylic adhesive to play a fixed role;
3. Dual-guide Copper foil conductive, mask, coating conductive adhesive, the conductive, fixed role;
4. Foil Mylar: Cover, insulation, two kinds of coating process, one is on the surface of the copper foil adhesive can be coated from the glue to cover the insulation, and coated conductive adhesive cover, insulation, conductive role, the other is in the wheat pull on the coating self-adhesive rubber insulation, mask, conductive role.
5. Back adhesive copper Foil: Copper foil laminating tape, insulation, conductive, mask role, can solder.
Copper foil tape Use: Suitable for digital camera, mobile phone, DVD, Copper Foil Adhesive Tape HVD precision Electronic products, computer communications, wire, cable, high-frequency transmission, isolation electromagnetic interference.
