The PFG 1600 RF is a newly developed, water-cooled radio-frequency generator designed for various plasma and thin-film processes such as magnetron sputtering sputter etching reactive ion etching CVD plasma processes bias applications.
This unit is the smallest component of a new product line of compact, fully transistorized, µC-controlled RF generators.
The compact RF generator is mounted in a 19'' slide-in unit and is characterized by durability, reliability and good serviceability.
Protection against mismatching and overload, particularly important for processes utilizing plasma technology, is provided in the RF generator through overdimensioning of the electronic monitoring and protective systems.
All functions can be operated by remote control via an analog/digital interface ref. an RS232- C or RS485 interface; the RF generator can therefore easily be integrated in a process- computer controlled system. The generator is operated directly via a keyboard with function keys and a two-line LCD displays.
Communication with connected Hüttinger components (automatic matchbox, RF reversing switch, master oscillator, etc.), formerly via multl-conductor cables, is effected through a fiber-optical ring bus (LWL). This eliminates interference due to RF fields.
The generator is constructed and built according to the corresponding rules of VDE , especially VDE 100, VDE 160 and EMV-rules.

When the RF-Generator is inserted into a 19'' rack, it is recomended, that the back door of the rack is not too close to the generator. Otherwise the heated air from the generator will be immediately sucked-in again by the fan, and reheat the generator to excessive temperatures. Eventually an air duct or an air-guiding sheet should be mounted, so that the heated and the cool air cannot mix up.
