In the 14th International IC Symposium and Exhibition Shenzhen station spring exhibition, passive components occupy a large part of the "Jiangshan". There are more than 100 exhibition booths with a variety of electronic supporting products on display. Among them, there are many established companies in Edo, as well as many newly established companies in this field. Zhuhai Huaguan capacitor Co., Ltd. is the latest novice in this field. In fact, the market competition of passive devices can be expressed as tragic, and even some super large companies have poor sales and even face the risk of bankruptcy. When asked why to enter the market in such a competitive background, Xiao Zitian, the company's sales manager, confidently said: since we dare to enter, we have our own advantages. We devote all our energy to innovation! In terms of product line planning, we completely give up the product lines that have no profit in the market, such as conventional aluminum electrolytic capacitors, and avoid the tantalum capacitors of traditional large companies, and focus on high-performance surface mounted aluminum electrolytic capacitors. This kind of capacitor is difficult and widely used in security and other fields. Next, we will try our best to solve the technical challenges of high voltage and high capacitance capacitor design. Xinhang Electronics (Shenzhen) Co., Ltd., located in Longgang, Shenzhen, is another company newly entering the field, specializing in the high-end film capacitor market, with an annual capacity of 200 million. With the introduction of high-end capacitor production technology, the company constantly promotes the upgrading of new products and technology. Kcqb and kcmt series of polyester film capacitors and kcmp series of polypropylene film capacitors produced by the company have been widely used in various application fields such as electronics, communication, household appliances, advanced audio and entertainment equipment, motors, instruments and meters, automobile electronics and other application fields due to their high-end technology, complete series, strong complete set capacity and large batch. According to Shi Fengjun, deputy general manager of the company, the exhibition relieved many new and old customers, among which many new customers were attracted. The company, which has successfully passed through the initial stage of entrepreneurship, has exhibited its traditional fist product, magnetic chip capacitor. The company specializes in medium and high voltage ceramic capacitors and high-frequency capacitors. With their small size and reliable performance, they are widely used in power adapter, switching power supply, charger, household appliances and other fields. According to Cai Xin, business representative of the company, IIC, as a promotion platform, has played a very good promotion effect for the company's product promotion. Shenzhen new Kewei Electronics Co., Ltd., which is specialized in SMD capacitor sales, also participated in the exhibition, and showed visitors a full range of SMD surface mounted capacitors, including 0402 series with high capacity and small volume, which can provide rapid matching for communication terminals, household appliances, toys and digital consumer electronic products. Looking at the above exhibitors, it is not difficult to find a rule, that is, they must focus on a technical field, constantly innovate and constantly upgrade their products. However, in the current extremely fierce competition environment, the concept of "poor skills but large and complete" is out of date.
