CAP
Capacitors were the original electrical energy storage devices. They are now among the world’s most widely used electronic components, with a vital role in the drive systems of today’s electric and hybrid vehicles.
As capacitor technology continues to evolve, it could play an even bigger part in the mobility solutions of tomorrow.
Brand : BUHLEROur Leybold Optics CAP series offers high quality roll-to-roll metalizing of films used in roller-type capacitors, with standard coating widths in a range of 500 to 900 mm.
Thinnest film
2.5 micron
Automated free margin evaporator delivers consistent results
Our innovative oil evaporator generates unmetalized margins in the machine direction for increased consistency in your film capacitor manufacturing. The supplied quantity of oil is automatically managed depending on the total area of free margins, the winding speed and the layer thickness, and is controlled in a closed loop for lower costs and better environmental performance.
Cross control and length control
The wire feeding rate for the boat evaporation and winding speed is adjusted to ensure consistent layer thickness and uniformity for the batch. Layer uniformity is regulated in film width and length.
Improved layer uniformity and quality
The advanced aluminum evaporator is used for depositing aluminum layers in a range of 1 Ω/cm² up to 150 Ω/cm², using the innovative arrangement and flexible height adjustment of the individual sources to optimize layer uniformity. As well as pure aluminum applications, the evaporation source can also be used simultaneously with other sources for applications with layer stacks.
