Jiwei Network News On January 20, according to the results of the 2nd review meeting of the Listing Committee of the ChiNext Board of the Shenzhen Stock Exchange in 2022, the IPO of Hubei Dongtian Micro Technology Co., Ltd. (hereinafter referred to as Dongtian Micro) was successfully held.
According to the data, Dongtian Micro is a high-tech enterprise specializing in the research and development, production and sales of precision optoelectronic thin film components, and has self-research and production capacity of coating materials, the main products are camera filters and optical communication components, etc., which can be widely used in consumer electronics, vehicle cameras, security monitoring equipment and optical communication signal transmission, data centers and other application terminals.
After years of deep cultivation, Dongtian Micro has accumulated rich industry experience in the field of precision optoelectronic thin film components and mastered a number of core technologies such as optical coating material ratio development, optical film system design, optical path design, vacuum evaporation coating, magnetron sputtering coating and precision machining, which have been highly recognized by downstream customers and terminal brand owners.
Since its inception, Dongtian Micro has always adhered to technological innovation as the core, as of January 13, 2022, Dongtian Micro has 63 patents, including 8 invention patents and 55 utility model patents. The company attaches great importance to the improvement of R&D capabilities, with a series of core processes and technologies such as coating, silk screen printing, cutting, assembly and AOl automatic detection required for the production of main products.
Higashida Micro will apply the self-developed coating materials to the design of the membrane system, improve the coating process to improve the layer stress and tension, and combined with the independent research and development of micro-crack-free laser cutting technology, etc., it took nearly 3 years to develop and produce high-strength ultra-thin blue glass irred-cut filters with higher transmittance and lower reflectivity than the Japanese JSR resin materials of the same thickness, which have higher transmittance and lower reflectivity excellent optical effects, and have been installed in oppo, TRANSSION and other major camera modules.
In addition, Dongtian Micro has the production technology of spin-coated infrared cut-off filter, and the company has won the bid for the new project of spin-coated IR cut-off filter and will ship it in batches. At the same time, the company actively in the field of optical communication product layout, continue to carry out new product development and process improvement, has mass production OF tube caps and GPON filters, the company uses magnetron sputtering coating mode to produce CWDM narrowband filters, shorten the product film forming time, reduce production costs, through the band Ripple value control
After years of development and technology accumulation, Dongtian Micro's product models are constantly enriched and the production scale is constantly expanding. With high-quality product quality, adhering to the business philosophy of keeping up with the market demand, the company has won the recognition of many customers in the industry, and has entered the supply chain of the world's well-known camera module manufacturers and smart phone brand manufacturers, and ofofilm, Qiu Ti Technology, Xinli Optoelectronics, Shunyu Optics, Shengtai Optics, Tongxingda and other well-known camera module manufacturers at home and abroad have established direct and long-term stable cooperative relations, and established business contacts with Huiding Technology, a provider of fingerprint recognition solutions under the screen, and realized batch shipments, and the products are widely used in Huawei, Xiaomi, OPPO, vivo, TRANSSION, Samsung, Glory and other well-known brands of smart phones; optical communication components products have established long-term and stable cooperative relations with Suzhou Innolux, a subsidiary of Zhongji Innolux Co., Ltd., Mateda, Ruigu Optical Network, etc. under China Electronics Thirteen.
