The demands made on modern automobiles are steadily rising. More and more electronics are required to satisfy high expectations regarding comfort and driving safety. Electronic circuits are also increasingly being integrated in decentralized sensors and actuators. The more complex the electronic circuit boards become, the greater the need is to reliably seal the components off from moisture and water (corrosion). Long-term sealing performance is equally important in powertrain applications. The task here is to prevent engine oil from escaping.

Numerous applications for the automotive industry

The quality of any seal depends especially on the cleanliness of the contact surfaces. In these critical zones, Openair® Plasma cleaning assures targeted and effective pretreatment with high contour precision. For especially durable and corrosion-resistant sealing of adhesive bondlines, the PlasmaPlus® process developed by Plasmatreat is the ideal choice. In this type of plasma polymerization, a coating substance (precursor) is added to the plasma. The result is an exceptionally resistant corrosion protection seal.


Openair® Plasma – prerequisite for reliable distance and angle sensors

To increase production of its sensors for the automobile industry and machine building, Novotechnik changed its surface treatment technology. Instead of low pressure plasma and vacuum chambers, a shift was made to inline Openair® plasma, which tripled throughput.
