RF Power Supply Option
EXN Series
EXN4T-70W
アルバック
EXN series is a target switcher. It is used to switch power supply destinations to multiple DC sputtering electrodes and RF sputtering electrodes. It also can switch the output of multiple DC and RF power supplies and supply them to one electrode.
Features
- Possible to switch the output of the matching box.
- Since it is not necessary to install a matching box for each cathode, it greatly contributes to equipment cost reduction.
- Two types of switching methods are available: manual and motor drive. A water-cooled system that can handle higher power also available.
- Also can be used as a switch for DC power supply and DC pulse power output.
- Since there is only one matching box, loads that exceed the matching range cannot be used together.
