Based on the company's strategic planning, the company focuses on the design, production and sales of R&D, power semiconductor chips and devices, and pays attention to endogenous growth. Through the construction of fundraising projects and fixed-income projects, the stock and increment coexist, and the company is deeply involved in the field of power semiconductors, making it better and stronger, and accelerating the realization of import substitution.
At present, the company has more than 200 varieties of power semiconductor chips and device products, which are mainly used in household appliances, leakage short-circuit devices and other civil fields, reactive power compensation devices, power modules and other industrial fields, communication networks, it products, automotive electronics and other lightning protection and anti-static protection fields.
It is understood that the company's current downstream customers include: low-voltage electrical appliances mainly include Zheng Taihe and Delixi; The field of home appliances mainly includes Hisense and Midea. Protection applications mainly include Philips Lighting, Dahua, Weisheng Group and BYD. The field of power tools mainly includes Dewei and Tianning. There are also many high-quality customers in reactive power compensation, electronic power modules, motor accessories and other fields. The proportion is industrial control 30%, consumption 30%, automobile 10%, communication 10%, security 10% and others 10%.
In the domestic automotive electronics field, the cooperative customers include BYD and Roswell, which are mainly used for charging piles. At present, the market share of automotive electronics at home and abroad involved in the company's products is very small, so we need to continue our efforts. In addition, Jiejie Microelectronics is also one of the suppliers of Huawei Mate 30 series.
It is reported that the company relies on IDM model to carry out its business, which has formed certain competitive advantages and barriers. IDM business model, to a certain extent, ensures the supply of chip production capacity, has a deeper control over the quality monitoring and testing in the manufacturing process, and is conducive to improving the reliability and stability of products. In addition, the innovation changes in the field of power semiconductors are relatively small, and the long-term benefits of investing in the construction of fabs are good, which is conducive to the latecomers to catch up with international giants.
JJ Microelectronics' business cooperation includes not only thyristors, but also docking downstream manufacturers in the third generation semiconductor materials and MOS, and starting mass production.
