Guiding the electromagnetic field from the A-surface to the PCB board that hosts the microprocessor is often the more cost-efficient and robust solution.
Conductive rubber is available in many forms and shapes thus opens a wide variety of improvements and new solutions.
Polyform – The A-surface that guides finger and eyes.
Polyform is a new HMI technology that provides a customized 2D or 3D shaped user interface.
This innovative surface - developed by Abatek - can integrate capacitive functions, touch display elements as well as buttons.
Various combinations regarding shape and surface structure such as glossy, matt, brushed, leathery and more are possible – even seamless.
Polyform is the perfect differentiator to support both the eyes and fingers to find capacitive traces.
Important: The Polyform surface is self healing!
Capacitive electrods on flexible foils.
Flexible foil with conductive traces using different materials can be assembled with adhesive tape or co-molded to the existing A-surface to establish a selective capacitive function.
In combination with our Abatek Polyform technology the foil can be co-molded into to the surface.
For connecting flex tail to PCB use Silicone Connector.
Conductive Silicone Key.
Benefit from the combination of traditional keypad (e.g. sealing, pre-load, lighting, click feel) with innovative capacitive sensing – the conductive black material.
For hard A-surfaces without displacement a conductive silicone shape can be used as connector to bridge an air gap. See cone to the right that also supports lighting.
Conductive Damper-Spacer and SMT Silicone Key.
The conductive rubber serves as spacer, anti-vibration cushion and connector in one.
If a double function is desired a SMT Silicone Keypad with customized
Connector / Zebra
Silicone Connector / Zebra Strips.
Silicone connector is the ideal solution for electrical connectivity between two parallel plane surfaces without soldering, gluing or complex assembly.
Eliminate expensive ZIF-Connectors with Silicone Connectors to assemble the flex tail or any other multi-contact part.
It is used in millions of devices as illustrated to the right.
