According to reports, Kaola Youran's glass-based Micro LED wafer inspection equipment combines internationally advanced technology and its independently developed core algorithm, and has significant features such as high precision, high stability, and high efficiency. Among them, the equipment uses a high-precision magnification-adjustable optical system with a 20X optical accuracy as high as 0.16um. Combined with the company's self-developed "active learning" AI algorithm, it can not only accurately identify appearance defects, but also accurately classify defects. In terms of offset measurement, Kaola Youran effectively eliminates systematic errors caused by factors such as motion and distortion through calibration and coordinate system conversion., ensuring high accuracy of offset measurement, and the measurement error under standard chip testing is controlled within ±0.5um. At the same time, all core technologies of this device are independently developed by Kaola Youran, which not only significantly improves cost control efficiency, but also ensures that customers can enjoy a more cost-effective product experience. Official Weibo information shows that Kaola Youran’s intelligent inspection product line focuses on providing complete inspection solutions for the semiconductor manufacturing and packaging and testing fields. The team has top automation design capabilities, high system integration capabilities, and industry-leading AI algorithm technology. It provides intelligent inspection equipment to many domestic semiconductor-related companies, greatly improving the company’s product yield and production efficiency. Equipment includes but is not limited to COW/COT/COC testing equipment, LED bracket testing equipment, power device testing equipment, screen display testing equipment, glass testing, membrane testing and other series of products, providing customers with overall solutions for testing equipment.
