Functional Characterization


Shear test.
Shear tester DAGE 4000.
Functionalized iron sole.

An important criterion in the development of thick-film-based parts and components is the fulfillment of defined parameters. For their characterization, a wide range of analysis options is available in the group. These allow both the qualitative and quantitative determination of mechanical, electrical and thermal properties. The use of methods is possible in the product development stage as well as during the production and quality analysis.

An advantage of ceramic technologies is the higher component reliability under harsh environmental influences. To estimate the reliability values, a combination of artificial pre-aging and mechanical parameters is used.

Pre-aging can be used:



Electric online measurement

Storage for a defined period of time under constant temperatures

Up to 1000 °C


Stress from temperature changes (shock)

(-55 … +250) °C


Moist heat

freely programmable e.g. 85 °C/85 % r.F.


Salt spray test




The mechanical parameters are determined on the basis of pull and shear tests. The maximum force for pull and shear values is 100 kg. The shear test can be performed at temperatures of up to 400 °C.
