Recently, the "5745 High Thermal Conductivity Nitride Aluminum Ceramic Heat Sink" project independently developed by Chizhou Yunzhong Electronics Technology Co., Ltd. has successfully passed the scientific and technological achievement evaluation, with the overall technical level reaching "International Advanced", and has successfully completed the registration of scientific and technological achievements in Anhui Province, obtaining the "Anhui Provincial Scientific and Technological Achievement Registration Certificate" (Registration Number: 2026N993Y00002709). This authoritative certification marks that Chizhou Yunzhong has achieved provincial-level authoritative recognition in the technical research and industrial application of high thermal conductivity ceramic heat management materials, and has become another important milestone for Chizhou Yunzhong's continuous deepening of research and development in electronic ceramic materials.

Targeting the heat dissipation bottleneck and overcoming core technologies.

With the rapid development of 5G communication, laser, power electronics and the third-generation semiconductor industry, the heat dissipation requirements for high-power electronic devices have become increasingly stringent. The limitations of traditional heat management materials in terms of thermal conductivity, insulation, and thermal matching have become increasingly prominent. High-end nitride aluminum ceramic heat sinks have long relied on imports, becoming one of the key links that restrict the independent control of China's related industrial chain.

The "5745 High Thermal Conductivity Nitride Aluminum Ceramic Heat Sink" project that has been registered this time is precisely the specialized research and development project of Chizhou Yunzhong aimed at the above industry pain points. Based on the existing research and development, the project further optimized the comprehensive performance of the high thermal conductivity nitride aluminum ceramic heat sink, focusing on the core demand of high-power electronic devices for efficient heat dissipation. The project's R&D team innovatively integrated the DPC (Direct Copper Plating) metallization process and high-precision pre-prepared gold-tin process, thereby systematically solving the key technical problems such as the mutual constraints of performance in each process and the easy peeling of the metallization layer in high-temperature environments.

Through continuous optimization of core process technologies and product manufacturing processes, Chizhou Yunzhong has successfully broken through the performance bottlenecks of domestic similar products in terms of thermal conductivity, metalization bonding force, etc., achieving "Integrated High-performance Manufacturing of Base - Circuit - Solder". The developed "5745 High Thermal Conductivity Nitride Aluminum Ceramic Heat Sink" has high thermal conductivity, high insulation, and excellent mechanical properties, and can be widely used in laser, 5G communication base stations, optical modules, and other high-power electronic device fields, providing reliable thermal management solutions for the industry.

Focusing on domestic substitution and promoting self-reliance.

The successful development of this product not only fills the gap of domestic production of high-end nitride aluminum ceramic heat sinks, but also has significant importance for the development of China's high-end laser equipment and the third-generation semiconductor industry's self-reliance. With an integrated design and stable and reliable performance, "5745 High Thermal Conductivity Nitride Aluminum Ceramic Heat Sink" has the ability to compete with international mainstream products and provides customers with a more cost-effective and supply chain secure choice.

Relying on the platform of a listed company, accelerating the industrialization of achievements.

As the direct holding subsidiary of Suzhou Yunzhong Electronic Technology Co., Ltd., a listed company on the Sci-Tech Innovation Board, Chizhou Yunzhong has always regarded technological innovation as the core driving force, continuously increasing R&D investment, and focusing on the key material and core process technology research and development in the industry. This provincial-level scientific and technological achievement registration certification is not only an authoritative recognition of the company's R&D strength and technological innovation capabilities, but also lays a solid foundation for the subsequent industrialization promotion, market application and industry cooperation of this technical achievement. In the future, Chizhou Yunzhong will continue to focus on the electronic ceramic business field, deepen technological innovation, accelerate the transformation of scientific and technological achievements, and with more high-performance and highly reliable innovative products, contribute to the high-quality development of the electronic information industry and create greater value for customers.
