In the application of membrane switch screen printing
Welcome to visit and pay attention to our company website: http://anabolicos.net
Screen printing is widely used in the field of electrical engineering and information technology, and took away the electronic new screen printing screen printing market.Electronic membrane switch has small volume, light weight, good sealing, dustproof and good water resistance, novel appearance, safe and reliable, long service life, and many other advantages.In the application of electronic products is very broad.
Given the general differences in circuit board printing, membrane switch printing and for printing quality is generally high, to reduce the resistance of the circuit when the switch line printing, must ensure line has enough thickness.And screen printing ink layer thickness on the substrates generally can reach 30-100 microns, and ink layer is not easy to break, will be used in the production of membrane switch, screen printing will can bring benefit to the production.Membrane switch to contact switch, usually in the flexible get together carbon vinegar or vinegar membrane conductive paste printing contact the switch, make the circuit mainly include touch switch, touch switch, light touch keys, electronic panels, etc.Membrane switch structure is simple, it is the decorative panel, top and bottom electrode film, isolation layer for draping. The surface is flat flat thin body shape on the whole, in order to guarantee the quality of membrane switch, also from the circuit design, selection of material and printing technology, pay close attention to each part.To believe that, with the development of science and technology, the future will be very extensive application prospect in the electronic film.
