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 are publishing an overview of ion migration evaluation and the details of the testing conducted!

One of the reliability evaluation methods, the ion migration evaluation test, has become increasingly important as a pre-evaluation due to the transition of products towards being lighter, shorter, and smaller. This document presents an overview of ion migration evaluation and the details of the test implementation using an example of an evaluation test conducted at our company. We will also introduce the usefulness of the continuous measurement (In-Situ) equipment used in the evaluation tests.

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.
