Membrane Switches Printing Mesh
Screen printing is predominantly used to print the conductive switch lines and the adhesive layers in the construction of membrane switches. This is because screen printing mesh offers relatively large openings that help to print the viscous conductive, resistive and adhesive materials. In addition, screen printing offers a wide range of wet ink deposit thicknesses from which to create the circuits (from a few microns to several hundreds of microns). The majority of membrane switch graphic overlays are also screen printed.
