What are Membrane Keyboard and Keypads

Membrane keyboards or membrane switches are pressure design pads that have only outlines and symbols printed on a flexible flat surface. Keypads work by electrical contact between the keyboard surface and the underlying circuits when the key top areas are pressed with help of an external force. The basic principle behind the functionality of a keypad is that the contact behind the tactile key or non - tactile key closes an open loop of the circuit which ends on the flexible tail. Membrane keyboard and keypads can range from flexible keyboard, backlit keyboard, waterproof keyboard, embossed keyboard, hybrid keyboard, front facia keyboard, tactile and non - tactile keyboard and many more.

FLEXIBLE MEMBRANE KEYPADS AND KEYBOARDS

Flexible Membrane Keypads and Keyboards are widely consumed amongst input devices by medical, consumer electronics and industrial sectors. The keypads have buttons backed with or without metal domes underneath, depending on the choice of feedback whether it is tactile or non-tactile requirement of feedback. They have a flexible tail with or without connector based on design and application. Flexible Keypads are preferable in low to medium intensity applications. The electronic circuit for flexible keypads is screen printed on a substrate medium using conductive inks. Clik Dome has dedicated, advanced manufacturing facility for manufacturing precise and bulk flexible printed circuits.

SILVER FLEXIBLE MEMBRANE KEYPADS AND KEYBOARDS

Silver Flex membrane switch panels use screen printed silver and conductive inks on flexible polyester layers separated with an adhesive spacer. This design is most commonly used in flexible membrane keypads. It offers a compact, space-saving design. LiClik Dome is leading manufacturer, supplier and integrator of Silver flexible circuits into membrane keypads and keyboads. Silver flexible circuitry is more economical than electromechanical switch assemblies. The process of screen printing conductive silver inks onto flexible substrates poses less risk to the environment than chemically etched copper.

You have many design options with Silver Flex membrane switches:

Tactile and non-tactile with metal or polyester tactile domes•
Embedded LEDs
Backlighting with EL (Electroluminescent)
Protection against EMI/RFI
Standard connectors with .100" centers or ready for ZIF connections

A Silver Flex membrane switch also uses a graphic overlay that offers a variety of design options:

You can either screen-print or digitally print your products
Embossing the graphics, logo and buttons
Transparent or tinted display windows
Selective textures
Surface finishes with UV hard-coat

FPC - PCB MEMBRANE KEYPADS AND KEYBOARDS

Copper Flexible Membrane Keypads and Keyboards are great for small designs where space is limited, dense circuit patterns, and trace routing restrictions. Copper Flexible keypads use silver or copper layers that are laminated to a dielectric layer and then etched away. This switching technology allows you to combine the flexibility of a membrane keypad with the complexity of a rigid FR4 printed circuit board. The Copper Flexible keypads have the advantage- that they can "hard" solder the active and passive components together, making them a great choice for high-vibration environments. Copper Flexible circuits can be made using either polyamide (Kapton), depending on the interface requirements. The copper sheet is then laminated to the flexible substrate and chemically etched away leaving behind copper traces.

Copper Flexible membrane keypads come in a range of designs:
Double-sided and single-sided designs
Copper Flexible membrane Keypads have a lower electrical resistance and higher conductivity than traditional Silver Flex switches
Traceability and tight routing
They have a thin profile and is flexible
You have the option of plating in tin-lead or nickel
Tactile and non-tactile with metal or polyester tactile domes
Soldering can be done on LEDs and other components
