Printed Electronics

Expert since 1978

Printed electronics refers to electronic components, assemblies and applications that are manufactured entirely or partially using the printing process. Electrically conductive inks and pastes are processed. We carried out printing tests for the first membrane switch back in 1978. A conductive silver paste was used to print electrical circuits on foils. Today, we develop and manufacture flexible, thin and lightweight electronic applications for every industry. Printed electronics includes printed sensors, hybrid systems, heating foils, antennas and in-mold electronics.

The printing process

Printed electronics is a process in which the application is built up additively. The corresponding layout can be printed on different substrates. The electronics are printed using a screen printing process. Fully automatic production lines in sheet formats allow simple and cost-efficient handling. In-house electronics production also enables the assembly of other electronic components.

Capacitive sensor foil

Functional Films: Capacitive Sensor Films

Printed capacitive sensor films save space, are lightweight and can be individually illuminated. It is no longer possible to imagine a vehicle cockpit or household appliances without these sophisticated control units. Just like a touchscreen, the sensor films can be operated intuitively via light touches.

The biggest advantage lies in the individuality. The functional films are printed with the capacitive, translucent control panels entirely according to customer requirements: flexible key shapes and sizes can be applied to different film materials and thicknesses.

In-Mold Electronics

In-Mold Electronics

The in-mold process combines functional films with injection molding technology. The film is inserted into the injection mold and directly back-molded. This process seamlessly combines the functional film with the plastic housing. Special substrates and pastes are used to ensure that the printed functions withstand this deformation.

In-mold electronics combines function with design and is used, for example, in the automotive industry. Vehicle cockpit functions are embedded directly in the dashboard and operated like a touchscreen. Knobs and switches are then no longer necessary.

Flexible Hybrid Electronics

Two technology worlds combined into one: a printed function is combined with conventional electronic components. By contacting and fixating with conductive adhesives, components such as ICs or LEDs can also be integrated on flexible films.

A good example of a long-standing product of this technology is the membrane keypad with integrated LEDs: The circuit is printed, the LED is integrated using adhesives.

Flexible Hybrid Electronics are used where thin, lightweight and flexible electronic units are required. A technology that effortlessly meets the ever-increasing demands: the lightest possible weight, difficult substrates, hardly any space and unusual sizes.
