At this time, a set of efficient and accurate Mini LED AOI equipment is particularly important, and Kaola Youran's self-developed Mini LED module AOI equipment undoubtedly brings a new dawn to the industry.
The industry has exploded, leading manufacturers are facing difficulties in mass production
In the wave of booming Mini LED packaging industry, a certain head display manufacturer invested 1 billion yuan to build a direct display production line, which covers an area of 4 The "super factory" with an area of 10,000 square meters, a monthly production capacity of over 10,000 square meters, and an automation rate of over 95% carries the expectations of being an industry benchmark. However, problems frequently occur during the mass production stage, and technology and successThe "triple strangulation" of cost and efficiency has put the production line in trouble.
The process limit challenge is the first to bear the brunt. Under high-density packaging, problems such as micron-level die-laying accuracy requirements and light-mixing consistency are highlighted. The yield fluctuates dramatically during the trial production phase, and the single-point fault repair time is as high as 60 seconds per chip, which greatly reduces the mass production efficiency. The shortcomings in supply chain adaptability cannot be ignored. Traditional equipment and materials are difficult to meet the needs of high-refractive index encapsulation adhesives and high-reliability die-hardening adhesives. Forcible use leads to a spike in defect rates, or is forced to slow down production, hindering large-scale planning. The risk of out-of-control costs is a headache for manufacturers. The complexity of the process and the need for equipment upgrades are superimposed, pushing up the overall manufacturing cost. The technical advantages are offset by price barriers, and the market popularization process is hindered.
"Scale does not equal victory." How to break through the "hidden reefs" in technical details and transform production capacity advantages into market competitiveness has become the core proposition that this production line needs to solve urgently.
Koala Youran Mini LED AOI testing solution: full process control, reconstructing quality logic
In order to break through the mass production bottleneck, the head display manufacturer introduced Koala Youran Mini LED module AOI equipment into the Mini LED direct display production line. By deploying Mini LED post-solidification AOI testing equipment and Mini LED post-packaging AOI testing equipment, a closed loop of "pre-furnace interception + post-furnace inspection" is formed to build a full-process detection defense line for the Mini LED module process.
Front-of-furnace testing: Increase efficiency by 40%, build a solid first line of defense
Kaola Youran Mini LED post-solidification AOI testing equipment directly addresses the core pain points of high-density packaging with its three major technological breakthroughs. The combination of area array flying photography and marble platform effectively eliminates motion errors and vibration interference, ensures imaging stability, and increases furnace inspection efficiency by 40%. Its "active learning AI" algorithm realizes intelligent classification and accurate identification of defects,The detection rate is ≤0.01%, the over-inspection rate is ≤0.05%, and the classification accuracy is over 99%, which greatly reduces the cost of post-furnace repairs and misjudgment losses. Multi-coordinate system conversion and calibration technology outputs high-precision defect mapping and accurately guides the positioning of repair equipment, reducing yield fluctuations by 60%.
In view of new risks such as false soldering and foreign matter contamination caused by the high-temperature and high-pressure packaging process, Koala Youran Mini LED post-package AOI inspection equipment builds "front and back double lines of defense." The application of line scan imaging and multi-light source time-sharing system enables simultaneous detection of products during transportation, and the defect detection rate on the front is increased to 99.9%, and on the backThere is no way to hide the appearance defects of components. The AI-driven data closed loop generates defect classification reports and production monitoring dashboards in real time, increasing quality traceability efficiency by three times and providing strong data support for process optimization.

Technological integration and hardware innovation: Kaola Youran’s password for differentiated competitiveness
In a context where the missed detection rate in the industry generally hovers between 0.1% and 0.01%, and the average production line pass rate is stuck at 65%, Kaola Youran abandons the traditional "passive screening" idea and proposes a two-stage solution of "active interception + precise repair". Through the deep integration of "active learning AI" algorithm and high-precision optical system, as well as hardware system-level innovation, the AOI detection benchmark is redefined.
On the imaging side, high-precision grating ruler, spatial calibration technology and customized light source design can overcome complex defect detection problems such as bubbles and radiation, and improve imaging stability by 50%. On the algorithm side, active learning AI algorithms build a "recognition-positioning-classification" closed loop, support the automatic generation of multi-element arrays, and increase the generalization ability of new defects by 3 times. On the structural side, the combination of marble platform and cast gantry structure controls the vibration amplitude of the equipment to 0.002mm. Within micron level measurement accuracy is ensured.
The data confirms the value of Kaola Youran's solution: the missed detection rate is reduced to ≤0.01%, and the over-detection rate is controlled at ≤0.05%, which provides a solid guarantee for product quality; the repair link is advanced, which increases the repair efficiency in front of the furnace by 40%, greatly shortening the production cycle; the production line pass rate is lower than the industry average 65% jumped to 80%, and production efficiency achieved a qualitative leap.
Industry model: replicable and verifiable development paradigm
Kaola Youran provides a replicable and verifiable "high accuracy, high efficiency, and high delivery" development paradigm for Mini LED AOI. When the industry shifts from "scale competition" to "efficiency and quality competition", Kaola Youran provides the industry with a full-link solution from testing equipment to process optimization with the management thinking of "pre-interception", the technological integration of AI and optics, and the reliability support of hardware systems.
Recently, Kaola Youran's self-developed Mini LED module AOI equipment won the "2025 Outstanding Product Award" of the Expert Aurora Award. This honor is not only a recognition of its technical strength, but also a powerful testimony of its contribution to the development of the industry. With the help of Kaola Youran, this leading manufacturer is accelerating its move towards the center stage of the trillion-level display market with lower costs and higher efficiency.
As a company deeply engaged in AI industrial visual algorithm intelligent inspection, Kaola Youran has profoundly reshaped traditional industrial visual inspection with the "active learning AI" algorithm as the core engine. In the future, Kaola Youran will continue to forge ahead, light up a clearer beacon for the upgrade of the entire industry, and lead the Mini LEDThe industry is moving towards a more brilliant tomorrow.
