Zhou Ming, Technical Director of Hangzhou Zhongwei Optoelectronic Technology Co., Ltd analyzed the demand and standardization status of automatic testing and sorting equipment for domestic LED packaging manufacturers, and introduced the key issues of high-speed and high-precision LED automatic testing and sorting equipment, and LED Test and sorting equipment working principle, current technical status. This paper also discusses the standardization of online testing in LED package production.

        Zhou Ming pointed out that in the rapid development of semiconductor lighting technology, in order to efficiently produce high-quality LED products, automatic testing and sorting equipment in LED chip preparation, packaging and application is increasingly highlighting its product development and production process. importance. In the preparation, packaging and application of LED chips, especially in the chip preparation stage, a large number of automation equipments in production still rely on foreign products, and imported equipment is expensive, which is very unfavorable to the development of the industry. Some small and medium-sized enterprises can hardly bear the cost of expensive machinery and equipment. They have to use manual or semi-automatic equipment to detect LED chips. When performing parameter analysis and analysis on a large number of samples, the efficiency is very low, which makes the LED performance indicators of the products have obvious differences, thus affecting The quality and service life of its end products. Therefore, the development of automatic testing and sorting equipment is of great significance to accelerate the development of the domestic LED industry. It is extremely urgent to develop semiconductor lighting test and production equipment suitable for domestic LED enterprises, moderate price, comprehensive functions and reliable performance.  

        Zhou Ming believes that the requirements for automatic testing and sorting equipment in LED packaging applications are fast and reliable. As a complex opto-mechatronics product, the optical mechatronic system architecture design of automatic test and sorting equipment, LED light color high-speed high-precision detection system research, machine vision technology research, equipment reliability research, and equipment cost control etc. It is a key issue in the development of automatic testing and sorting equipment. Standardization of online testing, Zhou Ming believes that probe standardization should be studied; standardization of test spectroscopy system; standardization of tester and mechanical interface; standardization of networked centralized management interface protocol for test equipment; development of spectroscopic standard (white light, monochromatic light); Chips, LED packages, LED application color requirements, standard docking and other issues. The standard formulation can be organized by relevant units represented by the National Industry Alliance and the Ministry of Industry and Information Technology Standardization Development Group. Leading enterprises and related key enterprises with certain strength in the LED industry chain take the lead in formulating and publishing standards.
