Stressed!! But how much...?


Mechanical stress and strain in thin films is becoming increasingly important to developers. This effect leads to drastic changes in the properties and stability of thin films.
Precise control is therefore imperative, in the design stages aswell as in the quality assurance process during production.

To develop most powerful film systems with best results, the majority of coating companies need to measure and control stress in their films.
