In addition, tensile and compression tests in the sub-micrometer range can be carried out. With tensile and compressive forces up to a maximum of 500 N, the smallest gap changes can be resolved.
In summary, the following error mechanisms can be checked with the ZFW vibration test bench:
- Pump-out, bleed-out, dry-out
- Mechanical stability
- Particle delamination
- Embrittlement
- Agglomeration
- Adhesion and cohesion
During the measurement, the gap, force and the change in thermal resistance are recorded. The vibration test (FMC) uses a purely mechanical movement to simulate the real gap expansion of a driving or random profile. Influencing variables, such as driving profiles with specification of a sample mean temperature, can be checked here. As a result, it is now possible to make qualitative and quantitative statements about the change in thermal resistance as a function of the number of cycles or the change in gap (tension / pressure).
