Copper foil tape is a kind of metal tape, which is mainly used in electromagnetic shielding, electric signal shielding and magnetic signal shielding. The electric signal shielding mainly depends on the excellent conductive performance of copper itself, while the magnetic shielding requires the adhesive tape of copper foil tape Conductive material "nickel" to achieve the role of magnetic shielding, which is widely used in mobile phones, Copper Foil Adhesive Tape laptops and other digital products.
Copper foil tape is divided into single-sided adhesive and double-sided adhesive. Single-sided plastic coated copper foil tape is divided into single-lead copper foil tape and double-guided copper foil tape, single-conductor copper foil tape refers to the plastic surface is not conductive, Copper Foil Adhesive Tape only the other side of the copper conductive, ; Double copper foil tape refers to the plastic surface conductive, and the other side of the copper itself is conductive, it is said that double-conductor that is double-sided conductive. There are two-sided plastic coated copper foil tape and other materials used to be processed into more expensive composite materials, Copper Foil Adhesive Tape double-sided plastic coated copper foil its surface is also divided into conductive and non-conductive two customers can according to their own needs of the conductive To choose.
Copper foil has a low surface oxygen properties, can be attached to a variety of substrates, such as metals, insulating materials, etc., with a wider temperature range. Copper Foil Adhesive Tape Mainly used in electromagnetic shielding and anti-static, the conductive copper foil placed on the substrate surface, combined with metal substrate, with excellent continuity, and provide the effect of electromagnetic shielding.
Copper foil tape series
1. Pure copper foil conductive, mask effect;
2. A single conductive copper foil, masks (plastic surface is not conductive), coated acrylic glue from the fixed effect;
3. Double conductive copper foil, mask, coated conductive adhesive, conductive, fit fixed role;
4. Copper foil Mylar: mask, insulation, two kinds of coating process, Copper Foil Adhesive Tape one is in the copper foil surface coating can be coated with self-adhesive insulation from the role of the mask, and coated with conductive adhesive from the mask, Insulation, conductive role, Copper Foil Adhesive Tape the other is coated in Mylar coating self-adhesive insulation, shielding, conductive role.
5. Beijiao copper foil: copper paste Mara tape, from the insulation, conductive, matte effect, solder.
Copper foil tape Uses: Adapt to digital cameras, mobile phones, DVD, HVD precision electronic products, computer communications, wires, cables, high-frequency transmission, electromagnetic interference isolation.
The copper foil tape is provided with a printed PET layer, Copper Foil Adhesive Tape an ink layer, a composite adhesive layer, a nickel mesh layer, a copper foil layer, a pressure-sensitive adhesive layer and a release film layer in sequence from top to bottom, wherein, in the copper foil layer, The side of the pressure sensitive adhesive layer is provided with a honeycomb groove. The case through the use of printing grade PET as the outer layer of the material, not only to ensure the appearance of the product brightness, but also make the ink easy to apply, Copper Foil Adhesive Tape thereby improving the ink distribution uniformity; using low surface oxidation characteristics of copper foil, The honeycomb groove is arranged on the side of the sensitive adhesive to increase the contact surface area. On the basis of ensuring the electromagnetic shielding effect of the product, the adhesive force of the copper foil and the pressure-sensitive adhesive layer is further improved, and the structural stability of the product is ensured; Mesh to increase the product's magnetic shielding ability, while the honeycomb structure can be adhesive through the nickel mesh and copper foil bonding, to ensure that the composite adhesive layer, nickel mesh and copper foil layer of the three adhesive stability.
