Dongguan Dingtong Precision Technology Co., LTD (a STAR Market-listed company, stock code: 688668), founded in 2003, is a national high-tech enterprise specializing in high-end connectors and thermal management solutions. Based in the industrial heartland of the Guangdong-Hong Kong-Macao Greater Bay Area, the company upholds the core values of "pursuing excellence, embracing innovation, and excelling in specialization." It focuses on three key sectors: high-speed communication connectors, automotive connectors, and liquid-cooled thermal modules for optical modules, striving to become a global benchmark in the connector industry.

In the high-speed communication connector section, Dingtong Technology has strategically capitalized on the industry opportunities arising from the digital economy and AI computing power boom. The company has established a comprehensive product portfolio encompassing QSFP/QSFP-DD/OSFP series Cage and Wafer products, copper cable connectors, and Overpass products. Its transmission speeds fully cover 400G and 800G, and it pioneered the large-scale supply of 1.6T ultra-high-speed connectors, achieving technical specifications that meet international advanced standards. These core products, serving as the "neural network" for electronic device interconnectivity, are widely deployed in critical fields such as communication base stations, internet data centers, mobile storage, AI computing equipment, drones, autonomous vehicles, and rail transit. They form an efficient interconnection ecosystem with optical modules, providing essential support for global digital infrastructure development.

To address the thermal management challenges posed by 1.6T optical modules, the company initiated the development of liquid-cooled thermal modules in 2024. Leveraging its expertise in precision manufacturing and thermal management, the company successfully overcame the limitations of traditional air cooling technology, introducing a liquid-cooling solution tailored for ultra-high power density equipment. The product entered formal production in December 2025. By harnessing the superior heat transfer properties of liquid, this solution enhances cooling efficiency by several orders of magnitude, effectively resolving thermal management challenges at 1.6T speeds. It aligns with the global trend of data centers moving toward higher density and greener operations, providing reliable support for AI servers, intelligent computing centers, and other applications.

In the automotive connector section, Dingtong Technology has been at the forefront of the new energy vehicle (NEV) electrification and smartization trends. Specializing in R&D and production of high-voltage connectors, low-voltage connectors, busbars, and electronic control system connectors, the company's products strictly adhere to automotive-grade reliability standards, featuring core advantages such as high voltage endurance, vibration resistance, and low energy loss. With its exceptional product quality and technical adaptability, Dingtong has become a key supplier for leading domestic customers including BYD, Changan Automobile, Great Wall Motor, Hongqi Automobile, and X-peng. The company also provides integrated solutions for top battery manufacturers like EVE Energy and Nantech Power, actively contributing to the advancement of the NEV industry chain.

Leveraging its robust technical expertise and stringent quality control, Dingtong Technology has established a global network of client partnerships. In the telecommunications sector, its products are distributed through the world's top three connector manufacturers—TE, Amphenol, and Molex—to major international tech giants including NVIDIA, Cisco, Dell, and Google, making it a key player in the global high-end supply chain. In the automotive industry, the company has forged long-term strategic collaborations with leading automakers and battery manufacturers, steadily enhancing its market recognition.

As a STAR Market-listed company, Dingtong Technology has consistently driven its growth through technological innovation, focusing on a development strategy of 'specialization and refinement' to sustain its competitive edge.
