On September 2nd, the Automotive Electronics Industry Technical Seminar hosted by Kunshan Zhengyao Electronics successfully concluded at Shanghai Hongqiao Guest House. Conferences include BMS, New Energy Electronic Control, BCM, ECU, Airbag Control, Reversing Image, AVM, RKE, TPMS, Car Air Conditioning, Infotainment System, LighTIng, Seat Adjustment, Window Anti-Pinch, ADAS, Car Antenna, Nearly 100 electronics engineers in the field of car networking. Lilong Electronics, Jiashuo Technology, Qiangmao Group and Handan Group respectively shared the application and failure mode analysis, industry status and future prospects of vehicle-grade products in the automotive electronics industry. Automotive electronic unit distribution Seminar site Zhang Lu, the world's fifth largest electrolytic capacitor manufacturer, said that in recent years, automotive electronics technology has developed rapidly. It is foreseeable that capacitors will be used in more demanding environments and load conditions in order to meet the higher requirements of customers. Lilong Electronics has continuously introduced new products to the market. For example, 50G high vibration resistant products, the world's smallest patch aluminum electrolytic VZT series, lower ESR solid-liquid hybrid capacitors, and axial capacitors for EPS with 15 years of life. Zhang Lu stressed that in the selection of automotive capacitors, it is necessary to consider the ambient temperature, ripple current, DC voltage value applied in the circuit, the service life of the whole machine, the installation method and space, and other special requirements. Automotive aluminum electrolytic capacitors are developing toward miniaturization, low impedance, high ripple current, and long life. In the future, there are more products available from Lilong for high temperature of 125 ° C -150 ° C, high temperature surge resistance, high vibration and other harsh conditions. Jia Shuo, senior manager of Jiashuo Technology, said that its main products are surface acoustic filters (SAW) and quartz crystals, which have been cultivated in the automotive industry for more than ten years. Compared with other industries, automotive high-low temperature characteristics, frequency stability, products Consistency, impedance control, and vibration resistance are more stringent. For example, in the case of TPMS, the maximum temperature of the engine is up to 150'C, the frequency deviation is controlled in a relatively small range, which is almost challenging the physical limit of the material. It also brings new challenges to crystal manufacturers. Jiashuo has mature application cases in RKE, TPMS, AVM, reversing images, ADAS, ECU and other fields. Jiashuo Technology feels that the domestic customer frequency component is over-reliant on imported brands and lacks autonomy, resulting in the main supply chain of the whole industry being in the dilemma of foreign manufacturers, lacking long-term competitiveness and thus limited development, when the delivery is tight, the US and Japan It is usually preferred to meet the needs of large overseas customers. Jiashuo Technology is based on localization services and assists customers in circuit analysis matching to solve these problems. Q&A session He Shenghong, FAE Manager of Qiangmao Group, gave a detailed introduction to the application and failure mode analysis of diodes and TVS products in the automotive electronics industry. Qiangmao has the core advantages of semiconductor upstream and downstream integration, mainly engaged in the production of discrete devices such as rectifier diodes and power semiconductors. Last year, 6.6KW TVS and silicon carbide products for automotive electronics were introduced. He has extensive experience in BMS, LighTIng, and new energy vehicles. In this year, MOS and other power devices are seriously out of stock. Many European and American manufacturers have been paying more than 20 weeks, and Qiangmao still guarantees the delivery of car and electricity customers on schedule. In the speech on the status quo and future prospects of automotive connectors, Wu Zhanshao, senior engineering associate of the Group, said that when the downstream market puts forward more refined requirements, the standard of connectors will also increase, and the automotive connectors are moving towards safety and green. Development, diversification, modularization, etc., safety is high current, voltage, high-intensity vibration, high temperature, waterproof and reliability. Greening is the result of weight reduction, low energy consumption and environmental protection. Diversification is the structure, installation space, and size. Modularity is to meet customer needs and increase matching. About Kunshan Zhengyao Electronic Technology Co., Ltd. Founded in 2006, the company is a professional electronic component supplier.
