Flexible electronics

Industry solutions for the vacuum thin-film coating of flexible electronic products

Machinery and vacuum coating processes for precision flexible electronic and flexible optics products
In the world of electrical film capacitors, Bühler Leybold Optics is a reference brand name for roll-to-roll vacuum coaters. Our technical team has developed an extreme performance capacity with our LEYBOLD OPTICS CAP series; machines which have become a benchmark in the industry.

Further market segments are flexible electronic and flexible optical products which require roll-to-roll coating using precise magnetron sputter sources. Flexible printed circuit boards, low emissivity (low-e) window films and flexible touch panels are all products made possible by our unique and precise LEYBOLD OPTICS FLC series of sputter web machines.

The Bühler Leybold Optics applications portfolio
Precise high-performance components delivering high productivity combined with unique in-situ measurement of the coating process are the key requirements for machines carrying out deposition processes.

In the segment of electrical film capacitors we fulfill these demands with the LEYBOLD OPTICS CAP series, a modular and highly productive machine platform which is capable of handling even ultra-thin material such as BOPP substrates thinner than 2.5 µm. Precise aluminum and zinc evaporation are the machine’s basic processes, while segmented coating can be generated by using of our unique flexo print unit.

The new LEYBOLD OPTICS FLC series is the most advanced web sputter machine in the industry. Industrial robustness combined with high-precision magnetron sputter sources, planar and/or rotatable, makes this machine the backbone for the development and production of flexible electronic or flexible optical products.
