Rigid keyboards

Rigig Keyboards are based on typical PCBs (FR4 laminates), thickness between 1,5 – 3,5mm. Copper layer could be 0,018 or 0,035mm. High rigidity of this type make the keyboard robust and resistant to mechanical impact. It is posible to integrate mechanical components (screws, spacer nuts, battery holders etc.)

Keys are made using metal domes (gold or nickel plated); typical diameters 8, 10, 12 up to 20mm. On the bottom side of PCB can be soldered SMD components (connectors, LEDs, resistors, capacitors, processors etc.) and THT components (for example connectors).

Self-adhesive keyboards

To make self-adhesive keyboards we can use one of tree kinds of copper lamite: thin FR4 – excelent for soldering electronic components, poliester (PET) – flexible, polyimide (Kapton) – extremally flexible, good for soldering. The advantage of this type is very low thickness (0,8-0,9mm). This make them easy to mount on typical plastic housings (usually hollow on the front is 1.0 – 1.5mm). The keyboard is easy to stick on almost all surfaces using acrylic adhesive.

Electrical connection with the electronic is realized by flexible flat cable (FFC) and ZIF/NonZIF. Also possible to mount CRIMPFLEX connectors compatible with typical cheap “goldpin” connectors.
