Film panel features and composition, film panel is a new type of Velvet (translucent) polyvinyl chloride, polycarbonate (PC) , polyester film (pet) to do surface decoration, and design a variety of symbols, words, patterns of decorative panels. Can Be widely used in household appliances, industrial instruments, instrument switch panels and manufacturers of brand. It changes the defects of traditional plate such as aluminum alloy plate, and becomes the most ideal new plate in modern times. This product is not only waterproof, dust-proof, wear-resistant, non-fading, easy to beautify decoration, easy to install, and directly use water, gasoline, alcohol to clean the surface of dirt, patterns are not affected. The membrane panel can be used alone or as part of the membrane switch. The membrane faceplate is composed of a mask layer and a back glue layer. Membrane panel materials are mainly PC, pet, PVC (basic do not use) . Printing process can be divided into front printing and back printing, respectively, for different materials and different types of film panels. There are both sand surface effect and smooth surface effect on the surface of composite sand. The main production process is in the material smooth and then printed matte ink, so that the mask appears matte effect.

Thin film panel conductive ink as printing materials, it is called”ink.”. Because of its appearance is a viscous paste, also known as conductive plasma, such as film surface conductive silver paste, conductive carbon paste, conductive nickel paste and so on. Conductive ink is often used in screen printing, it has the general screen printing ink printability, but with the general screen printing ink is very different. After the screen printing ink dries, the ink film is the printing insulator, the conductive ink has the obvious conductivity. Conductive ink is composed of conductive filler, adhesive, solvent and composite material additive because of its special function, different composition and different performance. The structure of conductive ink is composed of conductive filler, adhesive, solvent and additive. The structure of conductive ink in film covering parts, because of the particularity of materials, can produce a variety of different characteristics of products. For example, when the conductive filler is silver powder and the bonding material is glass powder, a high temperature sintered silver ink is formed on the film panel, and a photosensitive resin is formed by changing the bonding structure.
