Technical Parameters

Circuit Spacer – This layer separates the top circuit from the bottom circuit so that switch remains normally break until the keypad is pressed. The circuit spacer is a polyester spacer with adhesive on both sides.

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.

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.
