"The introduction of Openair-Plasma® was a milestone in the development of our sensor production."
Dr. Tobias Eckert, Head of Potentiometer Technology Centre, Novotechnik Messwertaufnehmer OHG

Engine control devices, anti-lock braking systems and on-board electronics are installed in the engine compartment and therefore constantly exposed to high temperature fluctuations and moisture. To protect the sensitive electronics, the printed circuit boards are encased in water- and dustproof housings. The sealing surfaces of these housings must be absolutely clean and free of grease and oil to ensure an impermeable seal.

Openair-Plasma^® enables automated and highly efficient cleaning and pretreatment of these surfaces prior to application of the sealing compounds and helps to achieve a high level of process reliability (plasma activation).

Plasmatreat has been approved as a plasma technology supplier by nearly all major manufacturers of engine electronics. Mature technology and worldwide service ensure trouble-free production processes.

Treatment of complex electronic housing geometries with the low-pressure plasma process

For electronic housings, particularly those with complex geometries, automating the selective scanning of the sealing surfaces can be challenging. In such cases, coating the housing using Aurora low-pressure plasma is a useful solution. Inside the low-pressure plasma chamber, a variety of parts can be cleaned and coated in one short cycle.

This plasma deposited coating provides durable corrosion protection and prevents moisture infiltration, (especially for housings made of aluminum and magnesium alloys). No additional chemical treatment or painting is normally required.
