Providing Testing Solution for Next Generation Sustainable Energy Tech

  • Forced discharge test of battery

    Background Effective January 1, 2009, the latest version of the Technical Instructions for the Safe Transport of Dangerous Goods by Air issued by the International Civil Aviation Organization (ICAO) added UN serial numbers for dangerous goods, and lithium batteries will be classified as lithium-ion batteries (UN 3090 and UN 3091) and lithium metal batteries (UN 3480 and UN 3481). The regulation states that lithium batteries cannot be transported by air if they do not come with a test report or certificate of approval based on UN38.3.

  • With the accelerated development of Mini-LED technology, ITECH high-precision power supply can still be used like this......

    Guide Autonomous driving technology makes the central control display become the core interaction point of the vehicle, and the driver can almost complete all operations except vehicle driving through a single display. Since 2022, a number of cars equipped with Mini-LED screens have been released, including NIO ET7 and ES series, Cadillac LYRIQ, Ideal L9, etc. Benefiting from Chinese and American automakers, the shipment of Mini-LED displays for vehicles will be about 140,000 pieces in 2022. It is expected that Mini-LED displays will explode in the field of automotive displays in 2023, and the shipment volume is expected to reach 450,000 pieces. As Mini-LED displays have gradually matured, it is expected that more car manufacturers will adopt Mini-LED backlight displays in 2024, and the shipment volume is expected to reach nearly 1 million units.

  • How to test the surface resistivity of semiconductor materials

    Many important parameters of electronic devices are closely related to the resistivity and the uniformity of its distribution, such as the reverse saturation current of the diode, the saturation voltage drop of the transistor and the magnification β, etc., which are directly related to the resistivity of silicon single crystal. Therefore, the resistivity test of devices has become an important process in chip processing, and its uniformity control and accurate measurement are directly related to whether power devices with better performance can be manufactured in the future.
