PLASMA – MEDIUM FREQUENCY (MF)

Glow discharge, polymerization, NOS and antifog phases require the creation of a plasma (activated gas) in the process chamber.
The gas (plasma) is activated through an electric field generated by a power supply, usually in alternating current (DC).
Instead ARZUFFI’s equipments are provided with a plasma activation system in Medium Frequency (MF) in order to reach a better quality of the process and reduce treatments time.

This technical device has the following advantages:

- Faster complete cycle time: 50% reduction of treatment time in the phases where MF is applied;
- Better quality of substrates: it’s possible to reach the desired quality level also in the presence of complicated structures and deep cavities;
- Cut in raw material costs: it’s not necessary to coil aluminium foils round the glow discharge cathode;
- Loading time reduction: it’s not necessary to replace the glow discharge cathode after every cycle because with the MF technology the cathodes must be replaced, in order to be cleaned, just once a day.

On the ARZUFFI’s equipments provided with MF technology are installed on the two sides of the fix half-shell two cathodes, that generally consists in two metallic plates that are designed depending on process chamber size.
