Maybe many people don’t know the names of these components, but everything from mobile phones and computers to smart TVs and new energy vehicles are inseparable from these products - multilayer chip ceramic capacitors (MLCC), chip resistors, chip resistors, etc.Sensors... These passive components are known as the "rice of the electronic industry". They perform basic functions such as voltage dividing, filtering, and current stabilization in electronic circuits, allowing circuit operations to run smoothly. They are the indispensable "invisible cornerstone" of every electronic device.
Guangdong Fenghua High-tech Co., Ltd.The company has been deeply involved in the field of passive electronic components for more than 40 years. It is the only company in China that has simultaneously achieved large-scale mass production of core passive components such as MLCC, chip resistors, and chip inductors. Both MLCC and chip resistors have been rated as national-level manufacturing individual champion products.
“Many people know that chip research and development is difficult. In fact, the technical research on passive components is no less difficult than that of chips. High-end MLCC involves material processes and has been monopolized by overseas giants for a long time.” Cao Xiuhua, member of the Party Committee and Vice President of Fenghua Hi-Tech, said.
According to Cao Xiuhua, raw materials and production equipment are two key factors that affect the quality of passive components, and foreign countries have long maintained a lead here.Nowadays, with the advancement of domestic technology, the pace of localized substitution has accelerated significantly.She said, "The thickness of our capacitor dielectric layer has increased from 2 microns to 0.8 microns, and we are currently working on 0.5-0.6 microns. In the same space, the thinner the ceramic dielectric film, the more layers that can be stacked, the larger the capacitor capacity, and the better the performance." At present, Fenghua Hi-Tech has achieved self-development and production of eight key main materials, including high-purity and ultra-fine barium titanate ceramic powder and nickel electrode slurry.
“This involves 1,000 layers of precision lamination technology.” She pointed to a small pink module and said that this is the result of the company’s full efforts.According to reports, the company has established a three-dimensional technological innovation system with clear hierarchies, collaboration and efficiency, and has established five national-level R&D platforms including the National New Electronic Component Engineering Technology Research Center. R&D investment has continued to remain high in recent years.To date, the company has applied for a total of 1,083 patents and obtained 775 authorized patents, with invention patents accounting for over 50%. It has led or participated in the formulation of nearly 30 national and industry standards.
“In the past, when the gap between the industry and foreign countries was large, fashion could survive through imitation, but now technological research has entered deep water areas and even "no man's land", and we must rely on independent innovation capabilities to open up new paths." Cao Xiuhua introduced that Fenghua Hi-Tech has made every effort to tackle shortcomings in the industrial chain, and has collaborated with domestic equipment companies to complete the localization replacement of more than 10 key production equipment, effectively solving the "stuck neck" problem.At present, the company has established a complete intelligent manufacturing management system and digital equipment management system. The high-end chip resistor and high-end electronic material intelligent factories have been rated as advanced intelligent factories in Guangdong Province, forming standardized and systematic intelligent management and control capabilities.
An MLCC carries the grand vision of independent and controllable China's electronic information industry.Fenghua Hi-Tech has spent more than 40 years of hard work proving that although basic components are "small", they are the "big" fulcrum that leverages the security of the trillion-level industrial chain.Driven by technological innovation, this long-established state-owned enterprise is promoting the "rice industry of electronics" to move steadily from catching up to running parallel to leading in some areas.
