China LED Industry Overview
After more than 30 years of development, China's LED industry has initially formed a relatively complete industrial chain. After experiencing the road of buying devices, buying chips, and buying epitaxial wafers, China's LED industry has already realized the independent production of epitaxial wafers and chips. At this stage, the number of people engaged in the industry is more than 50,000, more than 20 research institutions, more than 4,000 enterprises, including more than 50 upstream enterprises, more than 1,000 packaging enterprises, and more than 3,000 downstream application enterprises. In particular, the establishment of China's semiconductor lighting working group in 2003 marked the government's high hopes for the development of LED in the field of lighting. LED as a light source into the general lighting market has become the core of future industrial development. Under the impetus of “National Semiconductor Lighting Projectâ€, the national semiconductor lighting engineering industrialization bases in Shanghai, Dalian, Nanchang, Xiamen and Shenzhen have been formed. The Yangtze River Delta, the Pearl River Delta, the Triangle and the North have become the gathering places for the development of China's LED industry.
During the "Tenth Five-Year Plan" period, the main task of the country's development of the LED industry is to establish a semiconductor lighting technology standard system and intellectual property alliance through the construction of semiconductor lighting industry bases and demonstration projects, and to form an emerging industry of semiconductor lighting in China as soon as possible. The semiconductor lighting project is included in the “Eleventh Five-Year†scientific and technological development plan, as a key work to grasp. At the same time, according to the development status of China's own semiconductor lighting, the state has developed a semiconductor lighting industry development plan in line with its own development and a 2006 technology development road map. In China's semiconductor lighting industry development plan, it is planned to reach a single-light flux of 300lm by 2008, which can penetrate into the field of incandescent lighting.
In the upstream epitaxial wafer and chip production of LED, the United States, Japan, and the European Union still have huge technological advantages, while Taiwan has become an important LED production base in the world. At present, the world has formed a three-pronged industrial structure dominated by the United States, Asia, and Europe, and has taken the lead in Japan, the United States, and Germany. China, Taiwan, and South Korea are closely followed, and China, Malaysia, and other countries and regions are actively following. The echelon distribution. Although China has a certain gap in the production technology of LED epitaxial wafers and chips from the international advanced level, the huge domestic application demand has brought huge development opportunities to LED downstream manufacturers, such as display screens and landscape lighting fixtures. LED application products have been exported to the United States, the European Union and other countries and regions.
At present, the main research institutions of Yan and Chip at home and abroad include Peking University, Tsinghua University, Nanchang University, Institute of Semiconductors of Chinese Academy of Sciences, Physics Institute, 13 CLP, South China Normal University, Beijing University of Technology, Shenzhen University, Shandong University, Nanjing University, etc. The GaN epitaxial layer, the GaN-based blue wavelength drift, the internal quantum efficiency and the light extraction efficiency, the anti-light decay capability, and the heat dissipation level of the power chip are grown on the silicon substrate.
The main domestic LED epitaxy and chip companies are: Xiamen Sanan, Dalian Lumei, Hangzhou Shilan Mingxin, Shanghai Blu-ray, Shenzhen Fangda, Shanghai Lanbao, Shandong Huaguang, Jiangxi Lianchuang, Shenzhen Century Jingyuan, Guangzhou Puguang, Yangzhou Huaxia Integration, etc.
The main domestic packaging companies include Foshan Guoxing Optoelectronics, Xiamen Hualian Electronics, Ningbo Aimeida, Jiangxi Lianchuang Optoelectronics (10.14, -0.21, -2.03%), etc.; the downstream display industry mainly includes Shanghai Sansi, Xi'an Qingsong, and Beijing Li Yade.
What is Feeder on the placement machine? What is Feida on the placement machine? Feida is the main accessory of the placement machine. Its function is to mount the SMD patch components on the feeder, and the feeder provides components for the placement machine for patching.
In the placement machine, the feeder functions to supply the chip component SMC/SMD to the placement head in a regular pattern and order for accurate and convenient pickup, which occupies a large number and position in the placement machine. It is also an important part of choosing a placement machine and arranging the placement process. Depending on the SMC/SMD package, feeders typically have a variety of tapes, sticks, waffles, and bulk materials.
Tape feeders with the different size such as 8mm, 16mm, 24mm, 32mm, 44mm, 56mm etc.Panasonic Feeder,Insertion Machine Tape Feeder Unit,Tape Feeder Unit,Feeder Panasonic
