[Web Seminar for Electronics Manufacturers and Developers] The First Step in Solving Thermal Issues! 'Basics of Thermal Conductivity and Measurement Methods/Measurement Examples'

Introducing devices for measuring the thermal diffusivity of sheet-like and plate-like materials, as well as thermal evaluation devices for fiber orientation distribution!

Introducing Bethel's thermal property measurement devices. The "Thermo Wave Analyzer TA33/35" is a measurement device for the thermal diffusivity of sheet and plate materials, capable of measuring the thermal diffusivity of functional materials. The "Thermal Microscope TM" has been commercialized through joint development with the National Institute of Advanced Industrial Science and Technology's Measurement Standards Division, allowing for measurements in micro-regions and thin films. Additionally, we offer the "Thermal Imaging Scope TSI," which visualizes thermal conduction paths using infrared cameras and lasers, as well as the "Fiber Orientation Evaluation System TEFOD." 【Features of the Thermo Wave Analyzer TA33/35】 ■ High freedom of sample shape ■ Dynamic range from organic films to diamonds ■ Anisotropy evaluation through measurements in horizontal and vertical directions ■ Evaluation of defects and irregularities through distribution measurements *For more details, please refer to the PDF document or feel free to contact us.

Energy conservation is a challenge that must be addressed throughout Japan and the world in the future, and it is expected that the development of thermoelectric materials will also accelerate within this context. In fact, our company has received numerous requests for measurements of thermoelectric materials. Since the earthquake, there has been a particularly increasing trend, and if our measurement technology can contribute to the world of energy conservation, we are willing to cooperate in any way possible.

For measuring thermal properties of thin films and micro-regions. Micro-sized particles can also be measured freely.

The Thermal Microscope TM3 deposits a metal thin film on the sample and periodically heats it using a heating laser. It can now measure tiny particles that were previously difficult to analyze. For more details, please contact us.

Are you measuring the correct thermal conductivity of the thermal pad?

A thermal pad is a type of thermal interface material used for heat dissipation in CPUs and power devices. Due to its flexibility and relatively high thermal conductivity, it effectively reduces contact thermal resistance by filling the gaps between the heat sink and the device. Do you accurately understand the thermal conductivity of thermal pads? Thermal pads have elasticity, so their contact state changes with pressure. In other words, the effective thermal conductivity varies with pressure. Additionally, many materials exhibit temperature dependence in thermal conductivity, meaning that as the temperature increases, the thermal conductivity decreases. In this instance, we measured a commercially available thermal pad with a specification of 1.5W/mK. This is a soft type referred to as a soft thermal pad. The measurement device used is our steady-state thermal conductivity measurement device, the SS-H40.

• Thermo-fluid analysis

Even thin and small samples, as well as samples with high thermal conductivity, can be measured!

We are also able to measure the thermal conductivity of conductive diamonds. Normally, diamonds are insulators, but by doping with boron, they can be made conductive, allowing for the creation of high-performance electrodes. This enables redox reactions that are impossible with electrodes made from other materials due to a wide potential window, and they can be used in harsh environments such as strong acids and strong alkalis, offering significant advantages. Personally, I am particularly interested in their potential use in the recycling of CFRP. The measurements will be conducted using the ThermoWave Analyzer TA35. [About the Samples] The samples this time have thicknesses of 30μm and 300μm, and with a sample size of 10mm x 10mm, it can be said that measurement with ordinary thermal conductivity measurement devices is nearly impossible. Measurement is only possible with the ThermoWave Analyzer. The 30μm thick sample is matte black with a smooth surface. The 300μm thick sample is also matte black, but its surface was slightly rough. However, this level of roughness has no effect on the measurements at all.

• Thermo-fluid analysis

Leave the measurement of the thermal conductivity of carbon fiber reinforced plastic (CFRP) to us.

Carbon fiber reinforced plastics (CFRP), used in electric vehicles, aircraft, satellites, and rockets, require precise knowledge of thermal conductivity. For instance, when used in electric vehicles, understanding thermal conductivity is essential for heating performance and battery thermal management. Changes in electricity consumption due to heating performance and thermal management significantly affect driving range. Similarly, when used in satellites and rockets in the harsh environment of space, it is necessary to understand thermal conductivity to ensure heat resistance performance. With Bethel, you can accurately measure the thermal conductivity of this carbon fiber reinforced plastic (CFRP).

[Instructor] Representative of Digital Infrastructure Consulting LLC (DIRC) President of Regenerative Infrastructure Inc. (R11i) Mr. Takashi Furuta [Key Lecture Content] The data center market, which has continued to grow based on the internet and cloud, is expected to see a further explosive increase in demand due to the extensive use of computational resources that constitute generative AI. Meanwhile, in the Japanese market, foreign funds and global operators are leading development, while Japanese companies face challenges such as revenue opportunities, business continuity through exit strategies, reduced flexibility due to early securing of power, constraints of grid electricity, soaring construction costs, and coexistence with local communities. This lecture will organize these structural challenges and explore integrated location strategies for power, communication, and computational resources in the AI era, conditions for regional dispersion to areas like Hokkaido and Kyushu, and the business strategies that Japanese players should adopt.

[Speaker] Technical Advisor Shikenoh Furuno, Japan Automobile Parts Industry Association [Key Lecture Content] In February 2026, the U.S. and Israel attacked Iran, effectively closing the Strait of Hormuz, which led to skyrocketing prices of crude oil, naphtha, and other petroleum products, severely impacting the global economy. While renewable energy (renewables) is becoming more widespread, the reality of the energy crisis has highlighted the world's continued heavy reliance on crude oil. This has prompted a reevaluation of the value of BEVs, revealing distinct regional differences in the market. While Europe, Japan, and Southeast Asia are experiencing growth, the U.S. continues to see a contraction. In China, REEVs are also on the rise, and the movement towards a hydrogen society utilizing surplus renewable energy is accelerating. Moreover, with the evolution of AI and SoC, the value of cars is shifting from hardware to software, and the development of SDVs and autonomous driving is rapidly advancing. However, there are also concerns about being technology-driven. This lecture will organize these changes and provide an outlook on the future mobility society, including energy considerations.
