Capacitive Solutions
Add value at your fingertips.
Abatek provides technologies which guide the electromagnetic field from the surface to the PCB or foils detecting the capacitive interaction right below the surface.
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.

Foils
|
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.

Keypad
|
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.
For multiple conductive areas with or without displacement use a multi touch area keypad.

SMT Solutions
|
Conductive Damper-Spacer and SMT Silicone Key.
The conductive rubber serves as spacer, anti-vibration cushion and connector in one.
Size and shape are custom made.
The contact gets soldered on the PCB and is SMT placeable.
If a double function is desired a SMT Silicone Keypad with customized
force-way curve and electrical contact can be used.

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.

Silicone Inserts
|
Conductive Silicone Inserts.
Integrate an elastomer connector into the keypad and connect the capacitive surface to the PCB without losing functions like light guide, sealing etc.
