Figure | MEMS Editor’s note: This article comes from the WeChat public account “MEMS” (ID: MEMSensor), the author Mais consulted Wang Yi, the original title “Huawei invested in RF filter manufacturer Deqing Huaying”, 36 krypton released with authorization, slightlyCut down.According to a consulting report by Maims, recently, CLP Technology Deqing Huaying Electronics Co., Ltd. (hereinafter referred to as Deqing Huaying) has undergone industrial and commercial changes, and its investors have added Huawei Technologies Co., Ltd., China Guoxin Asset Management Co., Ltd., etc., andAt the same time, the senior management personnel of Deqing Huaying also changed. Guo Rui and Zhao Jun resigned as directors, and the newly added directors were Song Yanling and Zhang Jilong.Deqing Huaying was first established in 1978 and is a national key high-tech enterprise. It is located in the national-level Huzhou Moganshan High-tech Industrial Development Zone.The company started from the “Deqing Model” combining production, teaching and research in 1983, and has experienced more than 30 years of technological innovation and development. Its main business has expanded to three major categories of surface acoustic wave devices, piezoelectric, photoelectric crystal materials and RF modules.Is an enterprise with competitive advantages in the entire industry chain of materials, devices and modules in the industry.Deqing Huaying has internationally leading automated production facilities and strong technical force. It mainly develops and produces 3-8 inch lithium niobate lithium tantalate chips, surface acoustic wave filters, surface acoustic wave sensors, circulators and isolators..Relying on the technical advantages of the national academician expert workstation, the provincial key enterprise research institute, and the provincial enterprise technology center, the company adheres to the combination of independent innovation and the cooperative development of production, education and research, and has undertaken national, provincial and ministerial-level R&D and industrialization projects many times.Obtained more than 60 scientific research achievements, one of which won the second prize of National Science and Technology Progress Award.Deqing Huaying fully implemented the enterprise resource management system (ERP) in 2004, and implemented the warehouse management system (WMS) and manufacturing execution system (MES) in 2016; fully implemented the ISO9001 quality management system, ISO14001 environmental management system and IATF16949 quality management system.He has entered the top 100 electronic component enterprises in China nine times and won the title of “National Contract-keeping and Credit-honoring” Unit, Zhejiang Famous Brand and Zhejiang Famous Brand Product.The production of surface acoustic wave device series products and lithium niobate and lithium tantalate single crystal materials have been repeatedly rated as “Excellent Supplier”, “Top Ten Supplier” and “Product Inspection-Free Supplier” by users, and have won the consensus of the industryRecognized.At present, Deqing Huaying annually produces about 80 million various types of acoustic meter resonators and acoustic meter filters, which are often used in remote control, security, smart home and other fields. The types of crystal chips are mainly lithium niobate, lithium tantalate, quartz, etc., The company has a patent for crystal blackening reduction, which can solve the problem of burnout caused by high static electricity in high-frequency devices. Deqing Huaying can mass-produce blackened wafers with a thickness of 0.25mm to meet the needs of the international market; circulators and isolators are mainly usedIn the fields of radar, communication, remote sensing, telemetry, etc., it has the qualification to supply Huawei; in terms of SAW sensors, Deqing Huaying has developed a surface acoustic wave temperature sensor that can work in a passive manner, and can work in strongIn harsh environments such as magnetism, strong electricity and dust.Deqing Huaying’s enterprise architecture map. The eye-catching history of Deqing Huaying’s financing provided by Tianyanzha. It is also worth noting that in January 2020, Hubble Investment, a subsidiary of Huawei, has invested in a domestic SAW filter manufacturer-Wuxi Haoda Electronics.Co., Ltd. (referred to as “Hoda Electronics”).This time Huawei’s re-investment in Deqing Huaying is another important layout of Huawei in the field of RF filters.
