Membrane switch panel production can be divided into several steps. Substrate preparation: Select appropriate substrate materials, such as acrylic, silicone rubber, etc., and clean and treat them to ensure smooth and dust-free surface. Deposition of transparent conductive layer: Transparent conductive layer is deposited on the substrate. Usually, the material used is silver paint.
Photosensitive material deposition: The photosensitive material is deposited on a transparent conductive layer. Photosensitive materials are usually organic.
Membrane switch panel graphics: Graphic processing of materials using printing techniques.
Electrode deposition: Deposition of metal electrodes on a sensitive material, usually silver, copper, etc.
Packaging: Cover the electrodes with a protective membrane keypad such as a clear adhesive to protect them from damage.
Cutting: Cutting large area membrane keyboard panel to desired size.
The above is the basic process of membrane panel production. The specific production process may vary with different production processes.
