The copper foil insulation sheet
The purity is higher than 99.95%, its function is to eliminate electromagnetic interference (EMI), isolation electromagnetic damage to human body, to avoid voltage and current and the influence function. In addition, the grounding of electrostatic discharge has good effect. Paste, electric performance is good, can be cut into various specifications according to customer requirements. Application: suitable for all kinds of transformers, mobile phone, computer, PDA, PDP, LCD display, notebook computer, copiers and other electronic products, domestic electromagnetic shielding areas. It is a kind of metal tape, mainly used in electromagnetic shielding, electric signal shielding and magnetic shielding signal two, signal shielding is mainly dependent on the conductivity of copper itself excellent, rubber surface conductive material and magnetic shielding to the nickel foil tape to magnetic shielding effect, which is wideWidely used in mobile phone, notebook computer and other digital products.
The following general performance test of copper foil on the market at present commonly used to * * *: Material: CU 99.98% thickness: 0.018mm-0.05mm adhesive thickness: 0.035mm~0.04mm colloid composition: ordinary pressure sensitive adhesive (non-conductive) and conductive acrylic pressure-sensitive adhesive peel strength: 1 ~ 1.5kg/ 25mm (180 degree reverse stripping force test temperature of - 10 DEG C) ---120 C 4.5 ~ 4.8kg/mm tensile strength elongation of 7% ~ 10%MIN note: 1. test conditions for the temperature of 25 DEG C, relative humidity below 65 DEG C by the American ASTMD-1000 detection. Guangzhou copper tape 2. goods store, please keep dry indoor ventilation, domestic copper are stored for 6 months, the importing country can save more easily oxidized 3. products are mainly used to eliminate electromagnetic interference EMI, electromagnetic wave on the human body, mainly used in computer peripheral wire, computer monitors and transformer manufacturers. 4. copper tape divided into single-sided and double-sided coating coating. Copper tape coated adhesive is divided into single and double foil tape guide guide foil tape, single lead foil tape refers to the coating surface is not conductive, only the other side so that the single channel is conductive copper, copper conductive copper foil tape; double guide refers to the conductive coating surface, and the other side is copper conductor. It is a double-sided conductive double guide. There are double-sided adhesive coated copper tape used and other materials into composites relatively expensive, double-sided adhesive coated copper foil and the rubber surface also conductive and non-conductive two. Customers can according to their own needs to choose a pair of conductive
