Heyi Technology's new generation Mini/Micro LED intelligent maintenance solution provides strong guarantee

2021 is the first year of the country’s “14th Five-Year Plan”, and it is also the year of vigorous development of the new display industry. With the support of national policies and the joint efforts of enterprises related to the industry chain, LED-related industries such as new displays continue to maintain a rapid growth trend and have broad room for development. " The development direction of new generation display technologies such as LED and MicroOLED, Fujian has proposed to focus on a number of key technologies such as Mini/Micro LED, and Chongqing has focused on the development of Micro LED and other panels.

For example: Shanghai released the "Shanghai Electronic Information Industry Development "14th Five-Year Plan"" involving new types.In terms of display, it is mentioned that "expanding the production capacity of small and medium-sized displays, continuously improving the level of panel manufacturing technology, overcoming the industrialization technical problems of flexible displays such as folding and curling, and achieving technological breakthroughs in ultra-high-definition micro-display devices." This poses a great challenge to technological research such as integrated packaging technology.

With the continuous iteration of new technologies such as integrated packaging technology, MiniLED, Micro LED, etc., it has greatly promoted the technological upgrading of the industry, and the development stage of LED display with smaller pitch is coming soon. In order to grasp the new situation of the times, Heyi Technology independently developed and designed the "new generation Mini/Micro "LED maintenance integrated solution" not only saves more than 95% of labor costs, but also has a wafer repair rate as high as 99.999%. It steadily promotes Mini/Micro LED packaging efficiency and yield, helping many manufacturers reduce costs, increase efficiency, and improve service quality.

Heyi Technology has changed the traditional detection and repair methods. Through technological upgrades and lean management, it has integrated online appearance inspection machines, light-up inspection machines, etc.Testing machine, wafer removal machine and laser welding machine are combined to create an overall solution for Mini/Micro LED wafer inspection and repair. The entire process requires almost no manual operation, realizing automated and integrated substrate and wafer maintenance.

This combination of wafer defect repair developed by Heyi Technology has achieved high detection rate, high repair rate, and low false alarm rate. The four intelligent devices cooperate with each other. The main operation process is that the substrate wafer passes through the appearance inspection machine and the lighting inspection machine to determine the row and row position information of the defective wafer; then the detected defective wafers are removed with the help of a removal machine; and finally, precise welding repairs are performed.

Benefiting from the continuous emergence of new technologies and new solutions developed by high-tech enterprises such as Heyi Technology and the increasingly mature industrial chain, this will inevitably drive small-pitch LED displays to quickly move from the current professional display fields such as security, transportation, and energy to mass display fields such as retail, conference rooms, cinemas, and virtual studios, further accelerating the development of the LED display market scale.

The new display industry has a long way to go. Heyi Technology believes that with the support of national policies, the new display industry will continue to maintain a good development trend, and related enterprises in the LED industry chain are also expected to benefit from policy dividends and usher in greater development opportunities. Heyi Technology will continue to conquer Mini/Micro LED The bottleneck problem of intelligent detection and repair solutions has become a new force in promoting the large-scale application of Mini/Micro LED, and it is expected to leave a mark in the history of China's LED.
