Mechanical buttons, controls, and switches are used less and less in Human-Machine Interfaces (HMI). Instead, touch control panels have been introduced in almost all areas of electronics for good reasons. These can, for example, be made more appealing and intuitively controllable than conventional technologies. The functional display area merges with the decorative surface and is partially backlit. There are no mechanical buttons or switches on the front.
PolyIC has created a technology platform with silver based metal mesh technology on PET substrates in roll-to-roll production. This enables highly transparent and conductive films, mainly used for capacitive touch sensors. Within the KURZ-group we additionally have a huge know how for different integration methods, therefore we are able to find the best customized integration for a product.
Lamination with a double adhesive tape is the most widely used integration method for touch sensors. We also have a lot of experience in functional inmold-labelling IML of our touch sensors during the molding proces to create “inmold electronics” IME devices. Recently, we developed the Functional Foil Bonding (FFB) process. Here we bond the sensor on the part which has been molded (with decoration) and checked before. In the FFB process the sensor labels are pressed by a hot silicone die to the panel. A primer on the label is activated and the substrate becomes a little soft, so that the sensor label can follow a certain 3D shape of the panel surface. In this we can make a fully automatic integration process, where we can also deliver the customized machines within the Kurz-group.
In this presentation we will explain the sensor setup, the integration methods, as well as prototypes of innovative HMI devices and existing products on the market.
