Material Choices Of Membrane Keyboards

The material of the membrane switch and the panel is characterized by flexibility and high elasticity in addition to flatness and printability.

Mask material: conductive silver, conductive carbon, circuit Polyester that is PET.

Suitable for the film material of the panel layer, according to the type, we know that there are three kinds of PC, PVC and PET. 

According to the surface condition, there are sand surface (semi-transparent 3 film) and smooth surface (transparent). Membrane.

Most of the material of the capacitive membrane switch adopts polylipid materials, including polyvinyl chloride (PVC), polycarbonate (PC), and polyester (PET). 

Need to choose a capacitive membrane switch. Such as: flex life, chemical resistance, wear resistance, insulation performance, window transparency, drum definition, temperature level, UV resistance is available or not as a reference choice.

Usually adhesive is 3M 

Tail in Flex is PCB(FPC)

They are many layers of graphics, you can tell us your thickness, Pantone number, connector info etc, then we design the overlay switch for you.
