Embossing Button Membrane Keyboard

Membrane switch panel layer is generally less than 0.25mm, PET, PC and other colorless transparent material, is made by using screen printing technology, make exquisite patterns and text. Because the main function of the keyboard panel layer is to play the role of recognition and button reaction, so the selection of materials must have high transparency, high ink adhesion, high elasticity, anti-bending performance characteristics. Gasket layer is the gasket layer, its main function is to connect the panel layer and the line layer closely. In order to achieve the effect of sealing connection, the thickness of the structural layer is generally required to be 0.02-05MM, high viscosity requirements, need to have anti-aging performance; In the production, special membrane keyboard double-sided adhesive is generally selected. Some membrane switches require waterproof and high temperature resistance, so different materials must be selected according to the needs of silicon rubber pads.
