Factory Custom LED LGF Membrane Switch Overlay Big Window FPC Cable
1. Lower Circuit Layer – This layer is a 0.1mm--0.25mm thickness thermostable PET film printed with conductive silver ink and also dielectric oil. This layer terminates as a flexible tail that serves as an interconnector to controller PCBs or other IC.
2. Rear Adhesive – This adhesive layer bonds the entire membrane switch to the product surface, housing, or to a rigid support panel. UNIGREAT can use the proper adhesive type and thickness to bond your membrane switch to your equipment.
3. Graphic Overlay – PET/PC is usually the material of choice due to its fantastic chemical resistance and flex property . UNIGREAT can do digital printing, screen-printing, or apply both methods to ensure you get the right colors, textures and finish your design requirements.
4. Overlay Adhesive – This adhesive layer stick the graphic overlay to the top circuit layer, and is usually an acrylic adhesive. The material is same with the fourth layer. Only the thickness maybe different according to the actual situation.
