Recently, the monthly shipment volume of high-power laser ceramic heat sinks of Chizhou Yunhai, a subsidiary of Yunzhong Technology, has exceeded 2 million units, and its output value scale is at the leading position in the industry.

Since its establishment, Chizhou Yunhai has always focused on research and development and process improvement, achieving remarkable results in many aspects such as the research and development and production of high-power laser products. By adopting the DPC (Direct Copper Plating Ceramic Substrate) technology, the "High thermal conductivity ceramic electronic wire base board" was successfully developed. By fully leveraging the high thermal conductivity and high insulation properties of substrates such as aluminum nitride, silicon carbide, and diamond, prefabricated gold-tin ceramic heat sink products were developed, which are widely used in multiple fields including laser cutting, laser marking, laser drilling, and laser cladding. Ceramic heat sink devices for lasers have good insulation performance, low thermal resistance and high heat dissipation efficiency, which can meet the requirements of customers' chip eutectic bonding applications.

The management and technical teams of the company have been closely focusing on key points such as process improvement, efficiency enhancement, precision control, and yield optimization. They have been continuously working hard and making steady progress on the path of refinement. Through market research, they have precisely targeted customer groups, met customer needs, and achieved a 100% order delivery rate, earning high recognition from customers.

In terms of investment in cutting-edge technologies and intellectual property protection of technological achievements, the related projects have cumulatively applied for 15 patents, including 5 invention patents and 10 utility model patents. In addition, the core technology of laser ceramic heat sinks independently developed in recent years has also achieved multiple technical layouts and has obtained 6 patent authorizations.

With the increasing maturity of China's semiconductor industry, ceramic heat sinks for high-power lasers will also contribute to the development of new quality productivity and be widely applied in more emerging niche markets and fields. In the future, Yunzhong Technology will strive to make high-power laser ceramic heat sinks an industry benchmark through continuous technological innovation and product iteration and upgrading.
