Membrane Switch Keyboard

Common Membrane Switch Keyboard materials are PET, PC, PVC, Silicone rubber, etc.

When choosing a material, consider its properties, manufacturability, appearance and cost.

Technology and application of Membrane Switch Keyboard

There are many common film switch keystroke processes, and the following are some common processes and their application areas

1. Screen printing

Process analysis: The conductive ink (such as silver paste, carbon paste) is printed on the film material through the screen to form the circuit pattern.

Application: Widely used in film switch circuit layer production.

2. Laminating process

Process analysis: Multi-layer film materials (such as PET, PC) are combined by hot pressing or gluing to form a complete film switch structure.

Application: For the integral structure package of film switches.

3. Die cutting process

Process analysis: The film material is cut into a specific shape by the mold for the outline of the key or the window design.

Application: It is used for the processing of key shape, light transmission window or positioning hole.

4. Backlight process

Process analysis: The LED lamp or light guide material is embedded in the film switch to achieve the backlight effect of the key.

Application: Used in automotive electronics, medical equipment and other scenes requiring backlight.
