Dear Customers,

Valuable insights from our compact conference - request now!

Our compact conference in February was a complete success! The focus was on the latest developments in thermal analysis and simulation - both electrical and thermal. You were unable to attend but would still like to find out more?

Then get in touch with us!

We will be happy to provide you with the documents (in German!) and discuss your individual questions with you.

You can look forward to:

• CFD simulations for the analysis of flow and temperature distributions
• Material value measurements for the precise determination of material properties
• “Compact knowledge”

Let's get talking - we look forward to hearing about your topics!

Vibration tests with thermally conductive pastes

To improve heat dissipation in power electronics, conventional heat-conducting pastes are often used - a mixture of a viscous, non-crosslinking base substance (e.g. silicone oil) and heat-conducting particles made of ceramic or metal.

During operation, however, vibrations can lead to segregation: The paste separates into solid and liquid components and the oil escapes. This phenomenon is known as the bleed-out effect. Not only are the thermal properties of the paste impaired, but its service life can also be significantly shortened as a result - up to and including the failure of the entire power electronics.

We use our vibration tester to specifically test thermal conductive pastes for “bleeding out” - under the following boundary conditions:

• Maximum frequency: 200 Hz
• Maximum peak-to-peak amplitude: 95 µm (up to 50 Hz frequency)
• Temperature: 150 °C
