The World Cup has sparked the display trend, and Heyi Technology’s intelligent Mini & Micro Led maintenance line improves the yield rate of the packaging process

The World Cup schedule is currently in full swing, and the popularity of large-scale international sports events has ushered in a boom in the display industry. In the venue, the two LED displays at the main stadium of the World Cup, which are up to 20 meters above the ground and covering 70.78 square meters, as well as the large LED display screens in the eight stadiums of the Qatar World Cup, various peripheral commercial displays, live broadcast screens for radio and television performances, and even smart light pole screens on both sides of the city roads, are all supplied by Chinese LED companies, demonstrating the strength of the national display industry.

Off the field, since CCTV-16 has launched 4K ultra-high-definition World Cup broadcast for the first time, Douyin provides all 4K ultra-high-definition live broadcasts. From the perspective of display technology, the increase in ultra-high-definition broadcasts has greatly stimulated users' desire for higher definition and moreThe urgent need for large-screen event viewing equipment has triggered a consumer boom in high-end large-screen TVs. Data shows that in the first week of the World Cup, the sales volume of the online display market increased by 19.4% month-on-month, and the sales volume of the offline display market increased by 64.0% month-on-month.

The rise of the national LED industry and the display boom it has brought are all walks of life in the industry taking the lead in making industrial layouts in subdivided tracks that represent future development, and continuing to invest heavily in scientific research, innovation and market exploration. Today's display craze is inseparable from technological breakthroughs and innovations in the upstream and downstream parts of the display industry. Just as Heyi Technology has entered the era of small spacing and miniaturization in the LED industry, it has launched a fully automatic intelligent Mini & Micro Led maintenance line to help Mini & Microo The improvement in the yield rate of the Led packaging process provides advanced technical support from national enterprises for the display industry to increase production capacity and reduce costs.

Heyi Technology's fully automatic intelligent Mini & Micro Led maintenance line consists of several core equipment: online appearance inspection machine, online lighting inspection machine, online wafer removal machine, and online laser welding machine. Integrate all aspects of the Mini & Micro Led inspection and repair process to comprehensively improve the automation level of the maintenance production line. The specific process is:

The line appearance inspection machine finds missing parts, multiple parts, offset and extremely reversed defective wafer coordinate points through contour calculation, color feature extraction, grayscale calculation and image comparison.

The online lighting detector lights the controller to dock the product, controls the wafer required for testing, and confirms whether the wafer is lit.

In-line wafer removal machines remove defective wafers with precision.

The online laser welding machine uses CCD coaxial automatic positioning laser for precision welding.

The entire process does not require manual participation, achieving a fully automatic appearance. After precise lighting detection, defective wafers are efficiently and accurately removed, and then the laser welding machine uses laser to weld one-on-one. The decrystallized pads are complete and the solder joints are perfect in one go. With a very high level of automation, Heyi Technology's fully automatic intelligent Mini & Micro Led maintenance line has a high one-time repair rate, and the substrate yield rate after repair is as high as 99.99% or more.

At the same time, in order to be more in line with actual needs, Heyi Technology has also launched different maintenance plans. The first is a two-in-one automatic maintenance solution for crystal replenishment and soldering that can reduce the number of equipment and production lines, and the second is a de-crystallization replenishment solution that is suitable for direct display backlights.Welding crystal three-in-one automatic maintenance solution. In the two-in-one automatic maintenance solution for crystal repair and welding, the two-in-one equipment for crystal repair and welding will receive the wafer coordinates of the host machine and automatically perform crystal repair and welding, compressing the single-point repair time to 10 to 15 seconds, and the repair yield rate is also as high as 99.99%.

In the three-in-one automatic maintenance solution that is applicable to direct display backlights, after passing the appearance and lighting inspection, the PCB board enters the three-in-one fully automatic repair equipment of crystal removal, crystal replacement, and crystal soldering to complete the maintenance. This solution can significantly reduce the number of equipment and can achieve a 99.99% maintenance yield rate for backlight Mini Micro LEDs!

Heyi Technology has been deeply involved in the industry for many years, using innovative technology research and development and profound industry experience to launch the fully automatic intelligent Mini&Micro Led maintenance line. Solve the problems of low efficiency, low repair rate, low detection rate, and high false alarm rate in the industry, and use fully automated, highly intelligent, and high-efficiency equipment to help the industry reduce costs and increase efficiency to meet the display consumption boom.
