Description
Waste heat management, thermal runaway protection in batteries and electronic packaging is becoming more and more important as power densities of these devices increase. Thermal management of these complex systems is not trivial and requires a fundamental understanding of how components and interface materials work together to shed heat.
Our LINSEIS Thermal Interface Material Tester (TIM-Tester/TIM L58) is the perfect solution for thermal management optimization of these complex systems.
The TIM-Tester (TIM L58) measures the thermal impedance of sample materials and identifies an apparent thermal conductivity for a wide range of materials from liquid compounds and pastes to hard solid materials. The approach is consistent with the ASTM D5470 – standard.
- Automatic pressure adjustment using electric actor (up to 10 MPa)
- Automatic thickness determination using high resolution LVDT
- Instruments working according to ASTM D5470
- Full integrated, software controlled device
Thermal interface materials such as thermal fluids, thermal pastes (greases), phase change materials (PCM), solders or resilient thermal conductors are tested automatically by applying a pressure of up to 10 MPa (for ø 25 mm sample) and temperature of up to 300°C at the hot side.
The software interface allows the instrument to be operated automatically over a wide temperature and pressure range, while all test parameters are recorded in real time. This allows the user the freedom to fully explore an experimental design space for materials optimization. The sample holder is designed with sample size and shape flexibility in mind to accommodate actual size parts.
Typical samples include solids, pastes, pads and more. Different meter bars for varying applications (depending on thermal impedance of the sample materials and temperature range).
