Reverse bias test of power devices (up to 2000V)

It is possible to set bad standards (current values)! Evaluate device degradation and characteristics through high temperature and high voltage power supply.

At AITES Co., Ltd., high-temperature reverse bias testing (HTRB) for evaluating the oxide film and junction of power devices can be applied up to 2000V. By monitoring the leakage current during the test, the degradation status of the device can be grasped in real-time. Since the power supply is independent, if one device fails during the test, it will not affect the other devices. Additionally, it is possible to set a failure criterion (current value) and to cut off the power supply of the device deemed faulty at the time of failure judgment. 【Features】 ■ Real-time monitoring of the leakage current during testing allows for understanding the degradation status of the device. ■ The independent power supply ensures that if one device fails during testing, it does not affect other devices. ■ The power supply of the device deemed faulty can be cut off at the time of failure judgment. *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.

We have newly added a **"Frequently Asked Questions Q&A"** section to the Hyper CLT sheet website. It clearly summarizes many questions frequently asked by those considering the introduction of the product, such as "What types of civil engineering sites can it be used on?", "Can it be used on rainy days?", "Is it compatible with large machinery?", and "What is NETIS?". The Hyper CLT sheet is a lightweight wooden sheet utilizing wood CLT, suitable for a wide range of applications including temporary roads, access routes, and heavy machinery work yards. It is also registered as a **Ministry of Land, Infrastructure, Transport and Tourism NETIS registered technology "TH-250021-A"**. Since it is a new material, we will not leave any uncertainties unaddressed. We aim to create a website that makes it easy to resolve questions before introduction, including information on wood, NETIS, civil engineering, and CLT, and we will continue to enhance the Q&A section.

We have added a new **"Glossary"** to the Hyper CLT sheet website. In the civil engineering and construction industries, there are many specialized terms such as "CLT," "NETIS," "temporary roads," and "wooden lightweight sheets." Therefore, we have introduced related terms in an easy-to-understand manner so that those who are encountering Hyper CLT sheets for the first time can understand the products and technologies. Hyper CLT sheets are wooden lightweight sheets for civil engineering that utilize wood CLT and are registered under the Ministry of Land, Infrastructure, Transport and Tourism's NETIS technology as **"TH-250021-A."** We hope that by not only conveying the features of the product but also sharing the underlying technologies and terminology, users will feel a closer connection to Hyper CLT sheets. We will continue to enhance our website and provide clear information related to wood, NETIS, civil engineering, and CLT.

On September 15, 2026, we issued a press release regarding the wooden lightweight sheet "Hyper CLT Sheet." The Hyper CLT Sheet is a civil engineering sheet that utilizes CLT (Cross-Laminated Timber) stacked in an orthogonal direction. It can be used in various locations such as temporary roads, access routes, heavy machinery work yards, and material storage areas. The 5×10 version weighs approximately 230 kg, making it relatively lightweight and easy to install, remove, and relocate. Additionally, it offers environmental benefits such as reducing glare and metallic sounds typical of wood, as well as CO2 fixation. Furthermore, it can be proposed for the use of new technologies in public works as a **registered technology with the Ministry of Land, Infrastructure, Transport and Tourism "TH-250021-A."** Through this press release, we aim to expand the new wooden lightweight sheet that combines wood, NETIS, civil engineering, and CLT to more construction sites.
