"All indicators of the product meet the test requirements and the certification has been passed." Recently, good news came from Yangzhou Guoyu Electronics Co., Ltd., a subsidiary of Guoji Southern, that the fast recovery epitaxial diode power chip developed by the company passed the automotive regulatory standard certification assessment. , marking a new breakthrough in the automotive high-power chip project! Fast recovery epitaxial diode power chips are the "core" of power supply and inverter components. With the development of the new energy automobile industry, high-power chip products with higher voltage, lower power consumption and higher reliability are increasingly favored by the market. "This type of power chip has stricter and higher requirements, difficult research and development, and long verification cycle. Most domestic products of this type need to be imported." The person in charge of Guoyu Electronics said that to keenly capture the market demand, the company adheres to the innovation drive and deeply cultivates epitaxy quickly. R&D and mass production of diode power chip products. At present, it has developed into an enterprise with the most complete product specifications of fast recovery epitaxial diode power chips in China.
Apply strength to the difficulties and climb to the peak Walking into the Guoyu Electronics R&D workshop, the staff are busy and determined to move towards the "no man's land" and accelerate the collaborative research on key core technologies. The R&D team has conducted in-depth research and research on the design technology and process technology of automotive-grade fast-recovery epitaxial diode power chips, and is responsible for the Jiangsu Provincial Science and Technology Achievement Transformation Project "Auto-grade high-power fast-recovery epitaxial diode chip R&D and industrialization". As well as Yangzhou City’s key core technology research and catch-up projects, etc.
By pooling their wisdom to tackle key problems, the team has overcome a series of difficulties and achieved completely independent innovation in design, technology and manufacturing. "The fast-recovery epitaxial diode power chip products we developed can work in harsh environments such as high temperature, high humidity, and severe cold when used in the main drive of new energy vehicles." The technician said that the team referred to the automotive electronics reliability test standards to improve the power The test conditions of the chip, continuous optimization of the process, improvement of product yield, and guarantee of product quality will effectively improve the core competitiveness and self-sufficiency rate of domestic automotive fast recovery epitaxial diode power chips, and effectively enhance the security of the industrial chain and supply chain. Over the years, Guoyu Electronics has focused on the R&D and mass production of fast recovery epitaxial diode power chip products, tracking international cutting-edge technologies, and accelerating the transformation of innovation results. Currently, it has successfully developed nearly 200 models of products in four series, and the product quality is in line with automotive standards. Standard or industrial grade requirements, complete specifications.
