The first step in solving thermal issues! [For manufacturers and developers of electronic devices] 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.

• Other measurement, recording and measuring instruments

For evaluating thermal conductivity in thin films and micro-regions such as fillers, ceramics, insulating thin films, and semiconductor thin films!

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.

• Microscope

A fiber orientation evaluation system that is easy to analyze and understand! Anyone can safely perform measurements.

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.

We would like to express our congratulations on the continued prosperity of your esteemed company. Our company will be exhibiting at the following trade show, where we will be showcasing a number of products, including our new product, the Packaging Container Air Leak Test (Pin Hole Inspection) Device | MSQ-2003 series. We sincerely apologize for the inconvenience during your busy schedule, but we would like to cordially invite you to attend this event. 【 Trade Show Name 】 【 Dates 】 【 Venue/Booth Number 】

We will showcase our new product "BLFF," a palletizing foam gripper that weighs only 1.9 kg and measures 350mm×250mm, ideal for bulk picking. We will also introduce various products that cater to different work applications, including durable suction cups and solutions for bag handling. Additionally, we are implementing energy-saving proposals by replacing ejectors to reduce compressed air consumption, which has become a challenge in many industries. If you have any issues with adhesion or transport, please feel free to consult with us at the venue. ■ Lightweight Foam Gripper for Collaborative Robots "CVGC Series" Despite weighing only 1.9 kg, this gripper has a theoretical lifting force of 100 kg, maximizing the payload capacity of collaborative robots. ■ Gripper for Films This gripper is designed to transport thin films gently, minimizing marks left on the surface. By utilizing 3D printing, we can accommodate highly flexible shape designs tailored to specific workpieces and applications. ■ Energy Saving Comparison Panel "Why does a single ejector consume less compressed air compared to a multi-stage ejector?" You can actually verify the differences in compressed air consumption through a comparative display using a flow meter and actual equipment.
