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).

The RTCA/DO-254 guidance recommends that applicants define and implement HDL coding standards. This work begins with a planning process that includes the definition of the standard, how it will be implemented, and, if the process is automated, the evaluation methods for tools or results. A key issue is that the guidance does not have clearly defined formal standards, leading to questions about how to conduct a detailed review of HDL code. In this webinar, we will demonstrate the use of ALINT-PRO to enforce coding standards and highlight the benefits of streamlining the overall design review to meet the objectives of DO-254.

[Speaker] Takahiro Tachikawa, President of International University and Professor at the Graduate School of International Management [Key Lecture Content] In February of this year, the 7th Energy Basic Plan was approved by the Cabinet. What is the essence of this plan that the media and others do not convey? How will this plan impact the development and social implementation of hydrogen, ammonia, and next-generation fuels (synthetic methane, synthetic liquid fuels, green LP gas, etc.)? This lecture will delve into these points. In particular, it will focus on the content of the risk scenario, which is viewed as the main scenario among stakeholders in the energy industry, and the newly defined role of natural gas as an "important energy source even after achieving carbon neutrality."
