Three Omega Characterization System
Determination of thermal material properties of gels and pastes up to liquids is methodically highly sophisticated. Especially thermal conductivity and diffusivity are usually determined analytically. TOCS utilized the 3-omega method for determination of both material parameters and allows thermal characterization of liquid to solid material samples within few minutes.
TOCS is a measurement system for the determination of the thermal conductivity and diffusivity of solids, liquids, gels and pastes. Based on the bidirectional 3-omega method, innovative characterization chips allow for easy handling and fast measurement. Samples are simply applied on top of the characterization chip and the values for thermal conductivity and diffusivity are obtained using the convenient electrical measurement program of TOCS.
A straightforward approach
The TOCS measurement system is a complete solution, consisting of characterization chips, chip holder, electronics rack and user-friendly control and analysis software. The system is ready to use and a material sample can be analyzed within few minutes.
The characterization chips can either be cleaned and reused or used as one-way chips. The sample holder is flexible, connected to the electronics rack using ethernet cables and can also be inserted into a heating chamber at temperatures of up to 80°C for thermal conductivity measurements at elevated temperatures.

The characterization chips are based on thermally insulating borosilicate glass and contain three 3-omega sensors each along with two meander heaters. Electrical contact is realized with innovative tungsten through-glass vias to gold pads on the backside of the chips. Spring probes connect to the measurement hardware and the analysis software controls the whole characterization process which is conducted with just few clicks. Thanks to a magnetic clip system changing the chips is done with lightning speed.
