Flexible Electronics

Innovative flexible large area coating solutions for electronics.

Two of the greatest challenges facing the world today are the careful use of energy and the management of resources. Finding solutions in these areas is fundamental to ensuring our future comfortable existence and indeed to our planet’s survival.

Power generation plants, whether renewable or more traditional types, locomotives and automobiles, energy systems in buildings and industrial facilities – they all require capacitors with special features and characteristics for the efficient use and transfer of energy.

In the field of film capacitors Bühler Leybold Optics provides the appropriate technology to enable the high volume production of highly precise layers and structures on flexible plastic substrates. The robust and modular design, in combination with individual high-end components forms the basis for customers' added value, high quality products.

Film capacitors.
Several advantages are linked to metalized film capacitors when compared with ceramic or electrolytic capacitors, e.g. very low dissipation factors, high rated voltages, much higher ripple currents and very high surge pulses. Together with these advantages, the demand for tolerance stability and long service life from capacitors, such as DC-link capacitors in wind turbines, has become ever more important. These requirements are fulfilled by the "self-healing" properties of film capacitors. These “self-healing” properties are particularly efficient, when the metallization has been carried out with a special fault isolation pattern.

Film capacitors are used in the areas of E-mobility, smart grid, renewable energy, buildings and other domains. Our LEYBOLD OPTICS CAP series is designed for the future and to meet the demanding requirements of an unlimited range of metalized substrates for film capacitors. From standard to high-end applications, from thick to thin and smooth to hazy films, from plain to segmented designs, from thick to thin layers and from pure layers to layer-stacks; every conceivable combination can be realized in one system.

About Bühler Leybold Optics
