ベテル List of Products and Services

With the advancement of semiconductor devices, the thermal resistance of contact surfaces and interfaces has become an important issue. In AI chips, GPUs, NPUs, and power semiconductors, the amount of heat generated has been increasing year by year, and even small thermal resistances can lead to serious temperature rises. Furthermore, in advanced packaging technologies such as flip-chip mounting and heterogeneous integration, controlling the thermal resistance at the bonding interface is essential. There is also a demand for the development of higher-performance materials and precise thermal property evaluations for solder joints in conventional technologies, as well as TIM1 inside the package and TIM2 outside. Bethel's product line enables diverse thermal resistance evaluations on scales from micrometers to several tens of millimeters through thermal microscopes (TM), thermo-wave analyzers (TA), and steady-state thermal conductivity measurement devices (SS-H40).

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

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).

• Thermo-fluid analysis

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.

This device is an innovative thermal property measurement instrument that boasts world-class minimal resolution. It can measure the thermal properties of samples in detail at the point, line, and surface levels, accurately capturing thermal property value distributions on the micron order that were difficult to achieve with conventional devices. Furthermore, this device realizes high resolution while being a non-contact measurement tool, pioneering areas that were previously impossible with traditional technology. Equipped with the world's first technology, it can directly measure thermal conductivity under favorable conditions in addition to measuring thermal diffusivity. This device demonstrates unparalleled performance in situations requiring precise thermal property analysis in research and development. 〇 About the Measurement Principle 〇 The measurement principle of this device is based on the thermoreflectance method. This is one of the techniques for measuring the surface temperature of materials with high precision, particularly used to investigate the thermal characteristics of micro-regions and thin film materials. This method detects changes in reflectivity associated with changes in the surface temperature of the material and measures the temperature from those changes. The results obtained are expressed as the parameter known as thermal diffusivity. Thermal diffusivity is a physical quantity that indicates how much heat is absorbed when two substances are in contact. It can be mutually converted into thermal conductivity and thermal diffusivity based on specific heat and density.

In recent years, the miniaturization and high output of electronic devices have rapidly advanced, and as a result, thermal management (heat dissipation) has become a very important issue. Traditionally, heat dissipation has been maintained by using metals, but in recent years, it has begun to be replaced by "high thermal conductivity resins." High thermal conductivity resins are "lightweight" and have "moldability" compared to traditional metals, are "corrosion-resistant," and above all, have the advantage of being "low-cost." However, there is also the disadvantage of low thermal conductivity, and many material manufacturers are actively developing solutions to address this issue. It is expected that "high thermal conductivity resins" will become mainstream in the future. On the thermal properties blog, we introduce examples of thermal conductivity measurements of "high thermal conductivity resins." http://blog.thermal-measurement.info/archives/cat_50051425.html

Here is an example of evaluating thin polyimide sheets. Polyimide sheets are resin materials primarily used as insulating substrates and insulating layers in electronic circuits. This time, we measured the thermal diffusivity in the thickness direction using a ThermoWave Analyzer TA on a sheet with a thickness of 7.5 μm. Even with the same polyimide sheet, there are significant thermal differences depending on the thickness. When comparing examples of 25 μm and 7.5 μm using the measure of thermal diffusion time, there is nearly a tenfold difference. The thinner sheet diffuses heat in one-tenth the time. For in-plane measurements, it is relatively easy to achieve time resolution since the distance between the heating point and the detection point can be established. However, for thickness direction measurements, it is necessary to detect rapid temperature changes, which affects the basic performance of the equipment. Traditional measurement methods make the measurement itself difficult. Additionally, at a thickness of 7.5 μm, the thermal effects of surface blackening treatment cannot be ignored, so we have devised methods to minimize these effects during sample preparation and measurement. The measurement results are as follows: Thermal diffusivity in the thickness direction: 0.103 × 10^-6 m²s^-1. This value is approximately 30% lower compared to the 25 μm thick polyimide.

Yttria-stabilized zirconia is "an oxide based on zirconia, with the addition of yttrium oxide, which stabilizes the crystal structure of zirconia at room temperature." Applications include refractory materials, electrically conductive ceramics, materials for solid oxide fuel cell (SOFC) products, and due to its hardness and optical properties in single crystals, it is also used as a gemstone, such as cubic zirconia. In the case of fuel cell materials, thermal properties are important because the operating temperatures are high. Additionally, cubic zirconia closely resembles diamond and is often used as a diamond substitute. Like diamonds, it has a high refractive index, which gives it a sparkling appearance. The main difference lies in thermal conductivity. There are devices that can simply assess thermal properties to distinguish between diamond and zirconia. It seems that it is also used in thermal barrier coatings (TBC) for gas turbines. The measured result for thermal diffusivity was 1.13×10^-6 m^2s^-1. This value is 2 to 3 orders of magnitude lower compared to diamond. Our ThermoWave Analyzer TA allows for non-contact measurements. Many carbon-based materials can be measured without the need for surface treatment.

It is a unique device that evaluates the direction of fibers using heat flow. The 'TEFOD' is a fiber orientation evaluation system that can grasp the fiber state (orientation, relative comparison of quantity, variability) within a sample by utilizing heat flow. By observing heat flow, it allows for macro evaluation rather than micro evaluation. Evaluating the overall fiber orientation enables broader analysis. The measurement time is very quick at 1 minute (for one measurement point), and since it can be evaluated non-destructively, different evaluations can be performed on the same sample. The sample is spot-heated with a laser, and the heat transfer is observed using an infrared camera. By analyzing the observed infrared images, the thermal diffusivity can be quantified. Additionally, this product does not use X-rays, allowing anyone to perform measurements safely. 〇 About the Measurement Principle 〇 It is a type of periodic heating method called fiber orientation identification method. Spot periodic heating is performed, and the heat diffused in the plane direction is observed with an infrared camera at 360°. The thermal images obtained by the infrared camera are analyzed and quantified into thermal diffusivity. By converting it into a polar coordinate graph, the fiber orientation angle can be intuitively visualized.
