Awarded 'Annual Gold Supplier'

　　Looking back, taking root, and bearing abundant fruits.

　　For many years, our company has relied on a variety of high-reliability, serialized, and domestically produced products to cooperate with units in aviation, aerospace, electronics, shipbuilding, and weapons through multiple layers of collaboration and stable supply. This includes operational amplifiers, voltage regulators, modems, optocouplers, driver circuits, and sensors among other series of products.

　　Things have their sweetness and bitterness; those who taste them know. Paths have their smoothness and dangers; those who walk them understand.

　　The company has received positive feedback and praise from customers during its continuous development process.

　　Recently, we received the 'Annual Gold Supplier' award from Wuhan Aviation Instrument Co., Ltd., a subsidiary of the Aviation Industry Corporation of China. Achievements are visible confidence; spirit is an invisible force. We thank Wuhan Aviation Instrument Co., Ltd. for recognizing us; customer recognition is our greatest pursuit!

　　Wuhan Aviation Instrument Co., Ltd. is a member unit of the Aviation Industry Corporation of China and is a large to medium-sized state-owned enterprise mainly engaged in research and production related to aircraft de-icing technology, atmospheric data measurement technology, hydraulic fuel control system pressure sensor testing, as well as ejection rescue seat control/airdrop technology. Its related technologies are widely used in aviation, aerospace, weapons manufacturing, shipbuilding industries.

　　Looking ahead to the future, we will strive for further progress.

　　In response to the national military-civilian integration strategy and to pursue domestic development paths, Hangjing Company closely follows the pace of national domestic development efforts by continuously increasing R&D efforts for domestically produced products. In 2021, our company entrusted ten types of fully domesticated products to the Xi'an Saibao Industrial Technology Research Institute under the Ministry of Industry and Information Technology for identification tests. These products have successfully passed identification tests and are widely used in aviation, aerospace, weapons manufacturing and shipbuilding fields.

　　Our company has developed twelve major series of Hangjing micro-integrated circuits available for users to choose from.
