Copper foil tape is a kind of metal tape, mainly used in electromagnetic shielding, power signal shielding and magnetic signal shielding two, electrical signal shielding is mainly dependent on copper itself excellent conductive properties, and magnetic shielding is required copper foil tape Conductive material "nickel" to achieve the role of magnetic shielding, which is widely used in mobile phones, Copper Foil Adhesive Tape notebook computers and other digital products.
Copper foil tape is divided into single-sided plastic and double-sided plastic. Single-sided plastic coated copper foil tape is divided into single-copper foil tape and double-copper foil tape, single-copper foil tape refers to the plastic surface is not conductive, only the other side of the copper conductive, Copper Foil Adhesive Tape so called single-lead single-sided conductive ; Double-copper foil tape refers to the plastic surface conduction, and the other side of the copper itself is conductive, so called double-sided double-sided conductive. Copper Foil Adhesive Tape As well as double-sided adhesive copper foil tape and other materials used to process into a more expensive composite materials, double-sided adhesive copper foil its plastic surface is also conductive and non-conductive two. Customers can according to their own demand for conductive To choose.
Copper foil has a low surface oxygen characteristics, can be attached with a variety of different substrates, such as metal, insulation materials, etc., have a wide temperature range. Mainly used in electromagnetic shielding and anti-static, the conductive copper foil placed on the substrate surface, Copper Foil Adhesive Tape combined with metal substrate, with excellent continuity, and provide the effect of electromagnetic shielding.
Copper foil tape series Category:
1. pure copper foil with conductive, shielding effect;
2. Single guide copper foil conductive, mask (plastic surface is not conductive), coated with acrylic adhesive from the fixed role;
3. Double guide copper foil conductive, mask, coated conductive adhesive, from the conductive, paste the fixed role;
4. Copper foil Mylar: mask, insulation, two coating process, one is in the copper foil on the surface of the gum can be coated with self-adhesive from the mask insulation, Copper Foil Adhesive Tape and coated conductive plastic from the mask, Insulation, conductive effect, the other is in the Mylar coated with self-adhesive from the insulation, shielding, conductive effect.
5. Beijiao copper foil: copper foil paste Mara tape, from the insulation, conductive, shielding role, can be solder.
Copper foil tape Uses: Adapt to the digital camera, mobile phone, DVD, HVD precision electronic products, computer communications, wires, cables, high frequency transmission, isolation electromagnetic interference.
Currently on the market the most commonly used copper foil tape general test performance is as follows:
1. Ultra-thin and soft
2. Good electrical conductivity
3. High shielding effectiveness
4. Can not be burnt, easy to process
5. Non-electroplating products, in line with environmental trends
Copper foil tape applications
1. For grounding, all kinds of electronic components of the surface shield.
2. Die-cutting type, you can use notebook computers, LCD monitors, copiers and other parts of the need for electromagnetic shielding.
3. Products are mainly used to eliminate electromagnetic interference EMI, Copper Foil Adhesive Tape isolation of electromagnetic waves on the human body hazards, mainly used in computer peripheral wire, computer monitors and transformer manufacturers.
Electronic grade copper foil (purity of more than 99.7%, thickness 5um-105um) is one of the basic materials of the electronics industry, in recent years, the rapid development of electronic information industry, the use of electronic grade copper foil is growing, the products are widely used in industry With the calculator, communications equipment, QA equipment, lithium-ion batteries, civilian television sets, video recorders, CD players, copiers, telephone, air conditioning, automotive electronics, game consoles. Copper Foil Adhesive Tape Domestic and international market for electronic grade copper foil, especially high-performance electronic grade copper foil demand is increasing. Relevant professional organizations predict that by 2015, China's domestic copper-grade copper domestic demand will reach 300,000 tons, China will become the world's largest printed circuit board and copper foil base manufacturing, electronic grade copper foil, especially high-performance copper foil market Optimistic.
