    On December 21, the list of 2021 Science and Technology Awards in Guangdong’s Electronic Information Industry was announced. The key technology research project of Microwave High-Q Chip Multilayer Ceramic Capacitors for 5G Communications by EYANG Technology and the "008004 Ultra-Miniature Chip Multilayer Ceramic Capacitors" The "mass production and key technology research" projects won the second and third prizes of scientific and technological progress respectively. In addition, the two projects obtained a total of 8 patents, including 5 inventions and 3 utility models; 7 patents were accepted, including 3 invention patents and 4 utility model patents. The winning project technology was successfully promoted and applied in production, which greatly improved the technical level of the MLCC industry, and was highly recognized and supported by industry customers.

    In recent years, communication technology has been rapidly updated. 5G base stations, communication equipment, etc. have used higher and higher operating frequencies. The requirements for power loss caused by components in the signal transmission process have continued to increase. In order to meet the low signal loss and low signal loss of communication radio frequency circuits, High-quality, high-stability requirements, the "Key Technology Research of Microwave High-Q Chip Multilayer Ceramic Capacitors for 5G Communication" project takes Cu inner electrode high-power low-loss MLCC, high-frequency low-loss MLCC products as the main research and development objects, and introduces The introduction and development of international advanced production equipment and international and domestic material systems have broken through the four core technical difficulties: high-Q microwave dielectric ceramic technology: medium dielectric constant microwave ceramic (Sr,Ca)(Zr,Ti)O3 ceramic powder and dielectric ceramics and Cu Low-temperature co-firing technology of electrodes; preparation of highly stable slurry with ceramic and glass addition; low residual carbon debinding technology in N2+H2O atmosphere; accurate, low-cost and repeatable measurement technology for MLCC high-frequency parameters (greater than 5GHz). Through this project, the engineering and industrialization of Cu internal electrode high-power, high-frequency and low-loss MLCC products have been realized. The developed MLCC products cover a wide range of package dimensions, rated voltage, and nominal capacity, and the main technical indicators meet corporate standards: According to the requirements of Q/EY012A-2020 and Q/EY013A-2020, the products are widely used in 5G macro base stations, small base stations, network gateways and other industries. They are widely used by many well-known domestic and foreign brand enterprises, and have been well received by customers. They have successfully replaced foreign companies. Grade imported products.

    High-end terminal products continue to develop towards high integration, lightness and thinness, and SIP package modularization, and the available layout area and space of MLCC continue to shrink. In order to comply with the development trend of MLCC miniaturization and meet the company's strategic plan for ultra-micro and full series of MLCCs, EYANG Technology organized a project team to conduct "Mass production and key technology research of 008004 ultra-micro chip multilayer ceramic capacitors". The difficulty of the project It lies in the control of the production process when it is difficult to observe the product with the naked eye. The project solves the "development of ultra-small terminal electrode capping tooling", "rapid heating sintering technology", and "development of ultra-small MLCC terminal process" , "The development of ultra-small MLCC test process" four key technical problems. The 008004 series of MLCC products developed and mass-produced by EYANG Technology have reached the international advanced standard level, and the physical quality is in line with international peer standards. It is domestic It is the first to fill the domestic gap again. The breakthrough of EYANG 008004 ultra-miniature MLCC specifications is not only a requirement for the key development work of basic electronic components in the 14th Five-Year Plan of the country, but also contributes to solving the problem of high-end capacitor "jamming". 008004 size (0.25mm*0.125mm*0.125mm) ultra-micro MLCC is mainly used for products such as chip embedding, SIP packaging, smart wear and mobile device upgrades, which is similar to the existing 01005 size (0.4mm*0.2mm*0.2mm) In comparison, the volume is reduced by about 75%, and by reducing the mounting space, it can contribute to the further miniaturization and high integration of terminal products or modules.

    Innovation is the inexhaustible driving force for enterprise development. EYANG Technology has been committed to building the most cutting-edge miniaturized, high-frequency, and highly reliable technology research and development platform in the domestic MLCC industry. The company has invested heavily in Fenggang, Dongguan and Chuzhou, Anhui to build an international standardization industry. In the park, the world’s most advanced full set of MLCC (chip multilayer ceramic capacitor) production lines have been built, and a chip ceramic capacitor engineering technology research center has been established. Relying on the advantages of independent research and development and innovation system, the company has developed into one of the world's major MLCC manufacturers, especially in the domestic leading position in the field of miniaturization technology and radio frequency applications.

    This award is a full affirmation of the scientific and technological innovation achievements of EYANG Technology in recent years, and it is also a powerful embodiment of EYANG Technology's scientific and technological innovation capabilities. EYANG Technology will continue to uphold the corporate tenet of "Technology Leadership, Customer First", pursue excellence and create greater glories. !
