Under the weak market of the industry, accelerate the adjustment and transformation of product structure, and move towards Mini/Micro with high gross profit and high market demand. Entering the LED field has become the first priority for the survival and development of LED display industry chain companies.
At the same time, the GGII LED Research Institute (GGII) predicts that the global Mini LED market will reach US$5.3 billion in 2025, with a compound annual growth rate of more than 85%. By 2025, the global Micro LED market will exceed US$3.5 billion. The global Micro LED market size is expected to exceed the US$10 billion mark in 2027. In January 2023, more and more companies will make major breakthroughs in technological innovation and application innovation of Mini/Micro LED. The boom in the Mini/Micro LED industry has naturally aroused the enthusiasm of upstream and downstream enterprises in the industry.
However, the characteristics of Mini/Micro LED are that the panel wafer is extremely small and the layout is more dense. This is the main bottleneck for Mini LED to achieve large-scale mass production. As a company specializing in electronic assembly automation equipment for 21 years, Heyi Technology integrates R&D, production and sales. As a high-tech enterprise, it took the lead when Mini/Micro LED was in the ascendant, vigorously developed Mini/Micro LED inspection and repair technology, and launched a variety of innovative intelligent Mini/Micro LED inspection and repair solutions.
The core equipment of Heyi Technology's fully automatic intelligent Mini & Micro Led maintenance solution is an online solder paste repair machine and an online AOI Appearance lighting inspection machine, online crystal removal + crystal replenishment two-in-one equipment, online crystal removal + crystal replenishment + crystal welding three-in-one equipment.
Each setting The preparation process is as follows:
Online solder paste repair machine
Receive on Position the computer information, use a customized color camera to locate and remove defective solder paste, and automatically repair the solder paste.
Online AOI appearance lighting inspection machine
Light up the controller to connect the product, check whether the wafer is missing parts, multiple parts, offset and polarity reverse, control the wafer required for the test, and check whether the wafer is lit. Specially designed professional camera/optical lens to ensure the clarity of the object being measured.
Online crystal removal + crystal filling two-in-one equipment
Professional special camera/laser height measurement/special decrystallization knife to ensure the accuracy of decrystallization. The dewafer removal speed is fast, and it only takes 8 seconds to remove each wafer. A dual vision system is adopted, one group visually tests the tool positioning and appearance inspection, and the other group visually inspects the solder joints after removal to ensure the decrystallization effect. The stress sensing system is independently developed to ensure the protection of the substrate and effective response to the deformed substrate, and finally complete the wafer.
Online crystal removal + crystal filling + crystal soldering three-in-one equipment
Receive the row/column coordinates of the upper machine wafer, and automatically perform de-crystallization and re-soldering of the wafer. The spot size of the welding part can be automatically adjusted, suitable for various types of solder joints, and real-time monitoring of the solder temperature and real-time image monitoring of the welding effect can be achieved, and the solder joints are ready in one go.
This solution is suitable for the detection and repair of SPI rear substrates. The whole line configuration is conducive to the unification of data volume and facilitates a series of debugging and line replacement. The multi-layer guarantee reduces customer complaints and saves costs.
In order to meet the diverse maintenance requirements, Heyi Technology can customize the fully automatic intelligent Mini & Micro Led maintenance line to fit the actual production scenario to achieve flexible maintenance of Mini & Micro Led.
If the online AOI lighting appearance inspection machine is combined with the online de-crystallization + crystal-filling two-in-one equipment, it can be used in the back-end reflow soldering of the die-bonding work group to detect defective wafer removal and corresponding repair and re-solidification of wafers such as die-bonding deviation, leakage, multiple parts, polar reverses, etc.
and The combination of an online AOI light appearance inspection machine and an online three-in-one equipment of crystal removal + crystal filling + crystal soldering can be used to detect and repair defective types of substrates after reflow soldering, thereby reducing the outflow of defective products retained in the early stage and reducing customer complaints.
Since its establishment, Heyi Technology has been committed to the research and development and innovation of various automated manufacturing equipment. With profound industry experience and unique strategic planning,
