Thermal Flow Rate Evaluation System for Low Thermal Resistance Multilayer Substrates
F-CAL
It is possible to measure the multilayer materials, which is difficult with the laser flash method.
This system is to measure the heat flow rate of a sample.
A heating block is contact with the high temperature side of the sample, and the low temperature side of the sample is contacted with a low temperature block which works as both a cooling and a heat flow meter to perform measurement.v
It is possible to measure the heat flow rate flowing from the hot side to the cold side of the sample in a steady state.
The thermal resistance of the unknown sample can be evaluated by comparing with the thermal flow measurement results of a standard sample with known thermal resistance.
Applications
- Composite of metal + resin
- Composite of ceramic and metal
- Composite of carbon and semiconductor
- Evaluation of anisotropic materials
Features
- Heat flow rate (thermal resistance) in the thickness direction can be evaluated
- It is convertible to thermal resistivity using reference sample (Cu・SUS304, etc.)
- It is possible to meaure thermal resistance of a sample wich is made by joining a thin sheet material and a metal material
