Self-sufficient (hybrid) keyboard connecting functionality of keypad, front panel and electronic module. Printed circuid board can be 2.4mm thick (in some aplication up to 3.2mm) what makes the product very stiff and resistant for mechanical abrasions. Electrical functionality is realized using gold-plated metal dome (diameters 8.4, 10, 12, 16 or 20mm).
Kypad can be equipped with:
- pegs with thread
- metal or plastic spacers
- milled holes for connectors
- special inside layers connected to ground preventing the electronic for electromagnetic fields
- cutted windows for LED / LCD
Furthermore large area of the PCB is for the designer. He can place there SMD elements like LEDs, resistors and micro-controllers. In some situations there is possible to use THT elements for typical FR4 PCBs. Connections with other electronic parts can be made by common and cheap SMD/THT connectors.
