3.Top Circuit Layer – The material of this layer is special. This is a 0.1mm heat stabilized PET printed with silver-filled electrically conductive inks and also dielectric inks, which used for fastening metal domes.
4.Circuit Spacer – This layer separates the top circuit from the bottom circuit so the switch remains normally open until the keypad is pressed. The circuit spacer is a polyester spacer with adhesive on both sides.
5.Lower Circuit Layer – This layer is a 0.1mm--0.25mm heat stabilized polyester printed with silver-filled electrically conductive inks and also dielectric inks. This layer terminates as a flexible tail that serves as the interconnect to controller PCBs or other electronics.
