Flexible membrane switch membrane switch is the typical form. Such a flexible membrane switch is called, because of the membrane switch of the mask layer, the isolation layer, all of the circuit layer by a variety of different types of films composed of software. Flexible membrane switch circuit layers, good electrical properties are used polyester film (PET) as a switch circuit pattern wholesale carrier membrane switch PCB board, this layer is also dispensed feel shrapnel, down circuits. Since the polyester film has the property of, such that the membrane switch has good insulating properties, heat resistance, bending resistance and high elasticity. Pattern switching circuit including switching both online and lead PCB board with low resistance membrane switch, low temperature curing printed by electrically conductive paint. Therefore, the composition of the entire membrane switch, with a certain softness, not only suitable for use on flat body, but also with the surface mates. Flexible membrane switch lead and switch body itself is integral in making the switch to the online community when 2013PCB plate membrane switch, to bring together in one place the film in accordance with the design standards specified location and extending outwardly from the line As soft, can be bent, sealed lead wire and machine rear circuit. As a new class of polyimide film material and application of the advent of the PCB membrane switch company in Shenzhen, FPC flexible printed circuit board so that there has been no adhesive formulations FPC (generally referred to as "two-story type FPC" ). In the 1990s the world's developed with high-density circuit corresponding photosensitive coating film, making the FPC in terms of design has made significant changes. Since the opening of new applications, the concept of product form it took place in no small change, which it expanded to include TAB, COB broader substrate. In the latter half of the 1990s with the rise of high-density FPC began to enter the large-scale industrial production. It's fine circuit pattern to a more dramatic degree of development of high-density FPC market demand is growing rapidly. This information is provided by: Shenzhen Boer Zhuo Electronic Technology Co.
