Copper Flex Membrane Switches

Copper Flex Membrane Switches

 

Copper Flex Membrane Switches

Copper Flex membrane switches are ideal for smaller designs where dense circuit patterns or trace routing limitations exist. This design combines the ability to accommodate the complex circuit patterns of a FR4 rigid printed circuit board with the flexibility of a membrane switch. Copper Flex keypads also have the advantage of being able to “hard” solder active and passive components into the assembly, making it a good choice in high-vibration environments.

Copper Flex Membrane Switches

Copper Flex membrane switch panels can be produced using polyester or polyimide (Kapton) as the base material depending on your interface requirements. A very thin sheet of copper is laminated to the flexible film substrate then chemically etched away, leaving copper traces. The etching process is not as environmentally friendly and more expensive than screenprinting the silver traces used in Silver Flex membrane switches.

Copper Flex membrane switches offer you a variety of design options:

  • Single and double sided designs
  • Lower electrical resistance and higher conductivity vs. traditional Silver Flex membrane switches
  • Tight trace routing capabilities
  • Thin profile and flexibility of Silver Flex membrane switch
  • Plating options can be tin-lead, nickel, or gold
  • Tactile and non-tactile with either metal or polyester tactile domes
  • Pillow or rim-embossed graphic overlays
  • LED’s and other components can be soldered
  • Graphic overlays that can be digitally printed, screenprinted, or a combination of both
  • The graphic overlays can incorporate transparent and tinted display windows, as well as selective textures and UV hardcoat surface finishes
