Chaozhou Three-Circle (Group) Co., Ltd. (CCTC), founded in 1970 in Chaozhou, Guangdong, began as a traditional ceramics manufacturer before evolving into one of China’s earliest pioneers in industrial and electronic ceramic technologies. In its early decades, the company specialized in daily-use ceramics, then shifted toward industrial ceramics in the 1980s and 1990s, laying the groundwork for its entry into the electronics industry where advanced materials and precision performance are vital. By the early 2000s, CCTC had achieved large-scale production of ceramic ferrules—critical components in optical fiber connectors—earning a strong position in the rapidly growing global optical communications market.
Over the following years, CCTC broadened its portfolio to include alumina substrates for chip resistors, high-frequency and high-speed ceramic materials, zirconia precision components, and semiconductor ceramic packages, which are now widely deployed in 4G/5G networks, automotive electronics, industrial control systems, consumer devices, and new energy solutions. In 2014, the company was listed on the Shenzhen Stock Exchange (stock code: 300408), further accelerating its investments in R&D, automated production, and global market expansion. Today, CCTC ranks among the world’s leaders in ceramic ferrules, alumina substrates, and semiconductor ceramic packaging, with its products recognized for their stability, performance, and reliability in demanding environments.
CCTC operates under a solid quality policy of “Technology and Innovation, Excellence in Service, Continuous Improvement, and Customer Satisfaction.” The company has established comprehensive quality control across all sections, divisions, and process stages, ensuring continuous improvement at every operational level. Its main products are certified to ISO 9001 and IATF 16949 quality management standards, ISO 14001 environmental management standards, IECQ international electronic component quality standards, and UL safety standards. This rigorous quality system, combined with its technical innovation, has enabled CCTC to successfully enter the global procurement chain and earn broad recognition from international customers. Backed by over five decades of heritage, vertically integrated manufacturing, and a commitment to engineering excellence, CCTC continues to be a driving force in the global electronics supply chain, providing advanced materials and precision components that underpin connectivity, speed, and reliability worldwide.
