Capacitive touch sensors are replacing all types of mechanical switches in a very wide range of applications due to their low cost and high reliability: white goods, automotive interior, aviation, consumer electronics are only some of them.
Interfaces of capacitive touch systems typically consist of the sensor and the controller that combines a capacitance-to-digital converter (CDC) together with a microprocessor. The controller drives the sensor through conductive lines, usually called “traces”, on a standard PCB or flex circuit.
The specifications of the different applications set limitations on the sensor’s sensitivity. Traces routing, proximity to conductive parts, shielding elements etc. influence the final design. More often than not, you are left with a design that in theory follows generic guidelines but does not function when installed in the end product.
Join Fieldscale for this live webinar to learn:
- Touch buttons and sliders simulation tips
- Trace routing optimization techniques
- Material selection do’s and don’ts
This webinar is ideal for touch sensor designers from automotive, avionics, white goods or industrial applications that have no expertise in simulation software and want fast answers on how to move on with their project.
