industrial production platform Hauzer Flexicoat® 850 (figure

and development we can announce that the DLC coatings
produced with microwave technology are reproducible and
comparable to DLCs produced with the classic methods of
Plasma Enhanced Chemical Vapour Deposition (PECVD). We
are still busy with full characterization, but would like to
give our customers further insight in our progress with this

Turnkey Tool Coating
more Than Just Coating
By Michiel Eerden, product manager
physical vapour Deposition (pvD) coatings are used to increase tool productivity
substantially, but a coating process involves much more than just the right way
to deposit a coating. Cleaning, pre- and post-treatment, quality control, these are all
factors that can heavily influence the coating quality in a positive or a negative way.
in this article we will share some insights on the peripheral equipment that
complements the Hauzer coating machines.
Coating is just one of the steps in a 6-8-step program be-

In order to ensure perfect adhesion of the coating onto
the substrate material, pre-cleaning of the products is an
essential step. The size of the cleaning line needed depends
on the productivity requirements and the tool material.
Cleaning is removal of grease and dust, but oxides can also
be removed. There is the option of a multiple tanks
acqueous cleaning line or the option of a single chamber
cleaning unit, which needs a smaller floor space. The
cleaning steps with chemicals in a one chamber cleaning
unit are performed under vacuum. Chemicals will be stored
in buffer tanks, before they can be introduced in the
chamber for cleaning. To give an idea of productivity, the
