Days shares debut industry leading 90 kg class C axis sapphire crystal

Day March 9, 2013, Cmi Holdings Ltd in the salon international hotel in Jiaxing city held 90 kilograms of C axis sapphire crystal new conference. God will show for the first time through the company has industry-leading level of 90 kg C axis sapphire crystal, that day in the domestic LED industry leading position in technology, industry experts, customer representatives and government leaders were also on the day through the company successful production of 90 kg LED C axis sapphire crystal fully affirmed the significance. In Zhejiang province by the director of the Committee of Electronic Information Industry Office of Mr. Wei Zhenhua, Zhejiang Lighting Appliance Association Chairman Mr. Weng Maoyuan, Jiaxing City vice director of information industry research committee member Yang He, National Academy of Opto electronics chief expert Mr. Pan Guoqing, National Institute of Opto electronics industry renowned experts Ms. Liu Xin experts and Hangzhou Silan azure, Tsinghua Tongfang, Taiwan crystal technology and other business representatives attended the conference. Pan Jianqing, chairman of the board of directors of the company at the meeting to visitors to introduce a large size C axis sapphire crystal technology and the future direction of development. Pan Jianqing said: "the day the company has always insisted on the concept of science and technology development in recent years, especially in the field of LED sapphire crystal materials, continue to increase investment in scientific research, has made a major breakthrough in the crystal growth equipment and process of sapphire crystal growth, the crystal growth equipment and technology better fusion. The successful development of the 90 kg class C axis sapphire crystal production established a leading position in the field of sapphire crystal material industry in the domestic LED industry. Since the beginning of 2010, based in Tiantong company and foreign joint research and development of crystal growing technology and production equipment, adhere to technological innovation, have gone through three years of painstaking research, based on the mature production of 30 kg, 70 kg of crystal, in the recent successful production of 90 kg LED C axis Sapphire crystal. With this technical advantage, coupled with advanced production equipment, days of the company has been able to mature production 2 inches, 4 inches and 6 inches sapphire substrate, and has embarked on the development of a 8 inch sapphire substrate. In the window materials and other optical applications, also made considerable progress. After the meeting, participants visited with great interest the day's finishing workshop, have a more intuitive understanding of the advanced production equipment and clean environment. Tian Tong holding the current capacity of 2 inches substrate of 100 thousand / month, 4 inches substrate 50 thousand / month. Plans to the end of this year, the formation of an annual output of 1 million 150 thousand pieces of 4 inch sapphire substrate production capacity. TDG holding said, although the LED industry faces many unfavorable factors, leading to a slowdown in the pace of industrial development, but the LED industry positive long-term trend has not changed, I believe this experience baptism, LED industry will be more mature attitude facing new opportunities for development, burst out new vigor and vitality. Through the company's long-term bullish on the sapphire industry development, and insist on innovation and development, focusing on the development of large size, high quality and low cost of sapphire crystal and the substrate, the next step is according to the technical direction of the development of the market, the development of 150Kg more than C to the high quality crystals, to further improve the efficiency, enhance the removal of large size substrate core competence. The development of more than 6 inches to C and non-polar substrate, large size sapphire SOS high-end market demand. It is understood that in substrate processing, positioning the company for 4 days, 6 inches of high-end substrate, introduced international advanced cutting and polishing production line, have the core competitiveness in the key process of large size substrate slices, grinding, polishing and cleaning etc.. At the same time, the construction of a high standard of clean plant, with ten, 100, 1000 and 10000 production workshop nearly 8000 square meters, fully guaranteed the high quality of product processing. In the production process, supporting the industry's most advanced high-precision testing equipment, such as flatness tester, CandELa CS 20 optical surface analyzer, X ray TOPOGRAPH, and the use of SPC quality monitoring system. Has an annual output of 600 thousand pieces of 4 inch substrate production line, reached the international advanced level in the control of various technical indexes of TTV, BOW, SORI and LTV and so on, and has good consistency and stability, has been South Korea, Japan, Taiwan and other well-known manufacturers of the product sample has been identified, customers at home and abroad long-term bulk orders. Day long company crystal has the following advantages: 1, by modified KY method to achieve the growth, the world's largest C (90Kg) to the sapphire industry, the properties of A crystal growth to the same level, the dislocation density is below 1000pit/cm2, the rocking curve FWHM of 15 arc seconds, creating a C to the growth of high quality, the first heavyweight sapphire crystal. 2, C to 90Kg grade sapphire in more than 85% pass rate, provides the high quality sapphire crystal with high consistency stability for customers. 3, C to the growth, material utilization ratio A to crystal increased by 20 ~ 30%, 90Kg crystal can dig 2 Inch 4 inch 5700mm crystal, 1200mm crystal. 4, C to the growth, the maximum production of 12 inches (large size) to C crystal rods, substrate and components (is currently the only one can achieve the technology company), can significantly enhance the LED epitaxial chip efficiency and cost competitiveness. , 5 to C long crystal, longitudinal dig stick, reduce the stress and tension of the crystal, provides high quality guarantee for crystal substrate preparation warping and bending performance. 6, the improved method of KY crystal growth technology with independent intellectual property rights, has 11 patents, including 7 invention patents.
