Strain measurement in thermal shock testing.

Observing the behavior of strain in thermal shock testing! The test materials used are FR-1 and FR-4.

We would like to introduce the "Strain Measurement of Thermal Shock Testing" conducted by our company. A sample with a strain gauge attached was set up in the thermal shock testing device, and the wiring of the strain gauge was connected to an external data logger to record the strain data in real-time during the test. The strain behavior during the thermal shock test was observed for two types of copper-clad laminates, and it was noted that significant strain occurred with changes in temperature. It was found that FR-1 exhibited greater strain compared to FR-4. [Test Conditions] ■ Temperature Cycle: -30°C to 120°C ■ Exposure Time at Each Temperature: 30 min ■ Test Materials - FR-1 Paper Phenolic (Double-sided board) - FR-4 Glass Epoxy (Double-sided board) ■ Strain Gauge: Foil strain gauge for printed circuit boards *For more details, please refer to the PDF document or feel free to contact us.

Not only the joints of electronic components, but also the evaluation of fixed parts such as screws!

At AITES Co., Ltd., we conduct "Thermal Shock Testing." By repeatedly exposing samples to high and low temperatures, not only does stress occur due to thermal effects, but also due to the expansion and contraction of various parts. Repeated stress also adds to the overall stress. This test is conducted not only for the joints of electronic components but also for evaluating fixed points such as screws. 【Main Specifications of the Thermal Shock Testing Equipment】 ■ Internal dimensions: W650×H460×D370mm, Temperature range: -65 to 0/+60 to 200℃ ■ Internal dimensions: W650×H460×D670mm, Temperature range: -65 to 0/+60 to 200℃ ■ Internal dimensions: W970×H460×D670mm, Temperature range: -65 to 0/+60 to 200℃ *For more details, please refer to the PDF document or feel free to contact us.

Applicable to change observation, with support for additional analysis! We evaluate the subject in a time series and non-destructive manner.

During reliability testing, the samples change continuously. Do you have any questions such as "At what point did the crack occur?", "How does the degradation progress?", or "How much has it changed from the initial state?" By combining this with reliability testing, we will evaluate the subject in a time-series and non-destructive manner. 【Features】 ■ Applicable for observing changes in whiskers, migration, pressure resistance, solder evaluation, chemical erosion tests, and aging products in the market ■ Environmental tests and observation frequency will be conducted according to customer requirements ■ Additional analyses such as electrical characteristics, SEM observation, elemental analysis, and cross-sectional observation are also available *For more details, please refer to the PDF document or feel free to contact us.

In-Situ Continuous Measurement Reliability Evaluation Testing Service

In-situ continuous measurement reliability evaluation tests involve applying stress while measuring characteristics to conduct reliability assessments. ● Accurate understanding of failure time is possible In a read-out method where samples are taken from a stress environment at a fixed time, failure can only be understood at the timing of the read-out, making it impossible to know the exact failure occurrence time. In-situ measurement allows for an accurate understanding of failure time. ● Detection of recoverable failures is possible Recoverable failures can cause significant issues in the market. In most cases, the read-out method makes it nearly impossible to detect these recoverable failures, whereas in-situ measurement enables the detection of recoverable failures, allowing for accurate judgment and assessment. ● Monitoring of stress application conditions on samples is possible The stress application status and measurement data can be confirmed in real-time.

The "Mechanical Stitch Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

On November 6th (Thursday) to 7th (Friday), 2025, we held the "Human Body Day 2025" at the NAC Image Technology Akasaka Multi-Purpose Space. We have uploaded videos of the highlights from each company and the presentations that took place on the day to our website. We encourage you to take a look. ---[Report on Human Body Day 2025 is here]------------------- https://info.nacinc.jp/jintaiday2025-report ------------------------------------------------------------------------- On the day of the event, participants were able to experience a wide range of products in a hands-on session format, including motion capture, force plates, eye tracking, and human body analysis software. We received numerous comments from attendees expressing high satisfaction, saying, "It was great to gain various information all at once," which makes us very happy. NAC Image Technology will continue to provide "valuable products to our customers." We hope you will join us for our next event as well.

NDT Mart & Rental Co., Ltd. began selling its new electromagnetic ultrasonic thickness gauge, 'EMAT WIFI', on January 19, 2026. ◆ Electromagnetic Ultrasonic Thickness Gauge 'EMAT WIFI' The 'EMAT WIFI' is a thickness gauge that uses the electromagnetic ultrasonic (EMAT) method, which does not require a couplant (contact medium). Unlike conventional ultrasonic thickness gauges (UT), there is no need to apply a couplant; thickness measurements can be taken simply by placing the probe on the measurement target, making it ideal for beginners and screening in large-scale sites. It can measure materials with paint, scale, thick linings, and slight surface roughness, significantly reducing the hassle of pre-treatment. Additionally, it is equipped with WiFi communication capabilities, allowing for the confirmation and management of measurement data and waveforms in conjunction with smartphones and tablets. This facilitates smooth sharing of measurement results and data management on-site. It is optimal for measuring wall thickness and conducting corrosion inspections of plant equipment, piping, tanks, and steel structures. It contributes to the efficiency and reliability of thickness measurements in the field of non-destructive testing (NDT), such as maintenance inspections and equipment diagnostics.
