Upholding the spirit of craftsmanship to build the Hangjing brand.

Shaanxi Hangjing Microelectronics Co., Ltd. was established in 2001 and is located in the Aerospace Industry Base of Xi’an. The company integrates research and development, production, manufacturing, and testing and screening of thick-film hybrid integrated circuits and semiconductor integrated circuits, and operates as a sales-oriented enterprise.

The company operates over 6,000 square meters of industrial facilities, including more than 2,000 square meters of Class 10,000 cleanroom space, and maintains a testing center capable of conducting national military‑standard product testing, burn‑in screening, and environmental tests. With a workforce of over 100 employees, the company boasts a management team with extensive product‑management expertise and an R&D team of more than 30 members, including three experts who receive special government allowances from the State Council. Through years of exploration and innovation, the company has distinguished itself through cutting‑edge analog circuit design and ultra‑high‑temperature, harsh‑environment‑resistant products, earning the “Outstanding Supplier” award from numerous customers. It has also obtained high‑tech enterprise certification and secured over 40 patents, including invention patents, utility model patents, and integrated circuit layout‑design patents.

Since its establishment 25 years ago, Hangjing Company has leveraged its deep understanding of microelectronic devices and its mature, well‑refined manufacturing processes to develop products that exhibit exceptional resistance to shock, radiation, electrostatic discharge (ESD ≥ 4,000 V), surge events, and high temperatures (up to 225°C). The company’s R&D capabilities and product quality are among the most advanced in the domestic industry. It has designed and manufactured over a thousand types of high‑performance integrated circuits for hundreds of organizations across sectors including aerospace, aviation, electronics, defense, shipbuilding, and oil drilling, while providing superior technical support and fostering long‑term collaborative relationships. To date, it maintains stable, long‑term partnerships with more than 400 enterprises and institutions spanning over 80 cities.

In the field of space applications, more than ten types of products have already been deployed on small satellites. In the drive‑control domain, several high‑voltage, high‑power motor driver modules have been successfully developed and are now widely used in aerospace and unmanned aerial vehicle systems. In resource exploration, the company has set a domestic record for the long‑term stable operation of integrated circuits—including operational amplifiers, drivers, and power supplies—under extreme downhole conditions. Additionally, a range of self‑developed, high‑precision weak‑magnetic‑field measurement modules are extensively employed in systems for rotational speed measurement, gamma‑ray detection, pitch‑angle sensing, and attitude control, serving sectors such as aerospace, aviation, defense, and oil & gas. The HJAF3000HT quartz flexure accelerometer, which boasts fully independent intellectual property rights, has undergone rigorous long‑term testing in ultra‑deep well environments at 8,000 meters, setting a new benchmark for domestically produced accelerometers. Furthermore, in response to the specialized requirements of major oil companies like CNPC and CNOOC in the well‑logging field, the company has developed dozens of products characterized by extended service life, high reliability, resistance to temperatures up to 225°C, and robust performance in harsh electrical environments.

The company aligns with the national drive toward domestic substitution and actively supports the country’s development strategy. Building on in-depth research into the evolution of the microelectronics industry, it proactively addresses customers’ localization needs, leverages more than two decades of engineering‑application expertise to adopt cutting‑edge technologies and processes, and vigorously develops and manufactures market‑critical products that match the performance and specifications of their foreign counterparts, thereby helping users overcome challenges in system‑level domestic replacement. To date, the company has successfully developed over one hundred domestically sourced alternative products.
