Material value characterization

Material value characterization

Material values are material-specific parameters that quantitatively describe the different properties of the material. For the thermal design of components or processes, it is essential to know the physical properties of the materials used. For the simulative investigation of thermal paths, known physical properties must also be used. In addition to the thermal properties, the ZFW offers the measurement of other material properties.

ZFW TIM Tester

The specially developed TIM tester enables the thermal characterization of a wide variety of materials, such as thermal interface pastes and pads, potting compounds, adhesives, adhesive tapes, IMS materials, etc. The following is measured:
  • Thermal resistance Rth or RthxA
  • Layer or sample thickness
  • Thermal conductivity λ

3-Omega Method

The 3-omega method can be used to determine the thermal conductivity of thin, electrically non-conductive layers such as finish or paint.
  • Thermal conductivity λ of layers of a few micrometers

 T3ster - Thermal Transient Method

Description of the thermal-transient behavior of a component (mostly semiconductor) with the help of structure functions.
  • Thermal resistance Rth as a function of the heat capacity Cth
Further information

Laser Flash Analysis (LFA)

Highly accurate measurement of the thermal diffusivity and spec. heat capacity of solids with the help of light pulses. The thermal conductivity can then be determined from the data.
  • Thermal conductivity a
  • Spec. heat capacity Cp
  • Thermal conductivity λ

Further information

Dynamic Differential Calorimetry (DSC)

Very versatile and meaningful method for the thermal characterization of materials such as solids, powders, fibers / fabrics, viscous samples (TIM pastes or pads) and liquids. Some statements can be made from a DSC measurement:
  • Heat of fusion, crystallization, transformation and reaction (enthalpy) Δh
  • Specific heat capacity Cp
