Quality Supply PCB electrolytic copper foil with glue, plate thickness 0.007mm-0.075mm, suitable ..

1 Copper bands Product Description: purity higher than 99.95%, and its function is to eliminate electromagnetic (EMI) interference, isolation of electromagnetic waves on the human body injury, to avoid unwanted voltage and current affect functionality. In addition, after the ground for electrostatic discharge with good results. Paste strong, good electrical properties, according to customer requirements cut into various specifications. 2 foil Performance: Paste strong, good electrical conductivity copper foil 3 Uses: Suitable for all types of transformers, mobile phones, computers, PDA, PDP, LCD monitors, notebook computers, photocopiers and other electronic products electromagnetic shielding domestic places. 4 foil packaging preservation methods: 1. When saving goods, keep the room dry and well ventilated, made of copper typically stored for 6 months, the importing country can be saved longer easy oxidation 2. Test conditions for normal temperature 25 ℃, relative humidity. 65 ℃ to. 5 common sense: copper tape divided into single and double coated adhesive plastic cover. Sided adhesive coated copper foil tape copper foil tape guide is divided into single and double lead foil tape, single lead foil tape refers to a non-conductive plastic surface coating, only the other side of the copper conductive, so that a single lead that is single-sided conductive ; dual-lead foil tape means overlying conductive plastic surface, and the other side of the copper itself is conductive, so that double-sided guide that is conductive. There are double-sided adhesive coated copper foil tape and other materials to be processed into more expensive composite material, double-sided adhesive foil cover its plastic surface can be divided into two kinds of conductive and non-conductive. Customers according to their needs for conducting to select 6 copper selection Reference: Adhesive thickness: 0.015mm ~ 0.04mm. Colloidal components: ordinary pressure-sensitive adhesive (non-conductive) and a conductive acrylic pressure-sensitive adhesive. Peel force: 0.2 ~ 1.5kgf / 25mm (180-degree reverse peel strength Test). Temperature resistance -10 ℃ --- 120 ℃. Tensile strength of 4.5 ~ 4.8kg / mm. Elongation 7% ~ 10% MIN 7 reference foil inconvenience :( 1) The red dot to produce electrolytic copper foil before surface treatment, is point the acid-etched. (2) the black point of electrolytic copper foil surface treated, points are acid etched. Need to go through a period of storage before revealed. (3) white (bright spots) due to the production space humidity, mist point falls after a period of time to cause the surface of the electrolytic copper foil.
