Measurements

Our measurement technologies includes a wide range of different measurement methods and devices. Our core competencies are investigations of thermal nature. This includes thermal properties as well as the endurance and aging of electronic components and materials. In addition to the thermal characterization of substances, we also offer electrical investigations and special measurement solutions for specific problems.

Overview of the measurement methods:

Characterization of physical properties

The determination of thermal properties is part of our standard repertoire. In addition to thermal substance characterization, we also offer a large number of other investigations. The ZFW has a large number of modern, high-precision test systems available for the tests.

  • Thermal diffusivity a
  • Specific heat capacity Cp
  • Density ρ
    • Buoyancy principle: solids
  • Dynamic viscosity μ
    • Plate rheometer: liquids, pastes, etc.
  • Electrical conductivity σ
    • Measurement via spec. electrical resistance: liquids, pastes, solids, etc.
  • Dielectric strength E
    • Liquids, pastes, solids, etc.

Endurance and aging analysis by TIM

An important property for thermal interface materials is their resistance against aging effects. For this purpose, the ZFW has a large number of examination options in order to investigate endurance tests, including specially developed methods:

Life cycle and aging analysis of electronic components

With the help of the power tester, precise endurance predictions can be made for entire electronic systems or components. For this purpose, the systems and components are subjected to a cyclical, electrical load.

Heat sink characterization

Cooling with a liquid medium is often used to remove large heat flows. For this purpose, the ZFW's heat sink test bench offers the possibility of precisely determining the cooling performance and the prevailing pressure loss.
