Copper foil tape, tape is a kind of metal, mainly used in electromagnetic shielding, divide into two kinds, the electrical signal shielding and magnetic signal shielding signal shielding mainly depend on the excellent electrical conductivity copper itself, and magnetic shielding requires the adhesive surface of the conductive copper foil tape material 'nickel' to achieve the effect of magnetic shielding, and therefore is widely used in mobile phones, laptops and other digital products. The purity of the product description of the copper foil tape above 99. 95%, its function to eliminate electromagnetic ( EMI) Interference, isolation of electromagnetic wave to human body harm, avoid don't need the voltage and current and influence function. In addition, for the ground after the electrostatic discharge has a good effect. Paste, conductive good performance strong, can cut into various specifications according to customer requirements. The purpose of the copper foil tape is suitable for all kinds of transformers, mobile phones, computers, PDP, LCD, PDA monitors, notebook computers, copiers and other electronic products, domestic demand of electromagnetic shielding. The most commonly used on the market at present to the general survey of the copper foil tape performance is as follows: material: 99 CU. 98% of the thickness of the adhesive: 0. 015毫米~ 0。 4 mm thickness of the base material: 0. 007mm - 0. 075 mm elongation is 7% ~ 10% MIN stripping force: 0. 2 to 1. 5公斤/ 25毫米( 180 degrees reverse peel stress test) 4 tensile strength. Five to four. 8 kg/mm temperature tolerance - 10 ℃ - - - - - - - - - - - - 120 ℃ colloid ingredient: ordinary pressure sensitive adhesive ( Non-conductive) And conductive acrylic pressure sensitive adhesive
