In recent years, with the rapid development of communication and broadband network, the technology of transformer for network communication, which has become mature and developed, has radiated new vitality, and there have been new breakthroughs in technology R & D and output value. Especially with the diversified development of information industry, the popularity of network communication and consumer electronics is expanding rapidly, and the demand for network communication transformer is increasing day by day. Even the products of many enterprises are in short supply, and buyers are waiting for goods at the door.

　　With the continuous innovation of electronic technology, the miniaturization, planarization, functional diversity and performance superiority of electronic products have become the trend of the whole machine manufacturing industry, which requires the development of network magnetic devices towards short, small, light, thin, high electrical performance and high reliability; The network communication transformer is required to have high efficiency, low loss, low temperature rise and fast response speed. Patch type and film type transformers are more and more widely used in the market. In particular, the miniaturization, high-power and multifunctional development of mobile phones, digital products, mobile TV and other complete products puts forward the most direct requirements for the miniaturization of network communication transformers.

　　Today's management has integrated the application of advanced technology, accurate and rapid information and strategic direction, that is, the application of management concepts. With the rapid development of economic globalization, traditional manufacturing industry is facing severe challenges and new development opportunities. Many enterprises are faced with problems such as having to deal with a large amount of data, inefficient work sequence, and improper use of information. The consequences are delaying the production period, increasing costs, reducing flexibility, and delaying decision-making and implementation.

　　In recent years, with the rapid development of information revolution and scientific and technological innovation, information technology, network application, automation technology and intelligent production have generally affected every industry. Production and consumption activities will make full use of science and technology to improve production efficiency and quality of life. The impact of the Internet makes a new economic and social form brewing. In the future, whether multinational large enterprises or regional small and medium-sized enterprises must face global competition.

The application of network transformer is completely in accordance with the development of network market. Wherever the network is used, the trace of transformer can be seen.

(1) Standard network equipment, hub, router, switch, modem and network card;

(2) Computer devices, personal computers, Nb, servers, high-end workstations;

(3) Communication products, Internet telephone, data camera;

(4) Others, IPTV. The above is only the application of several indicators. As the network continues to develop, the application level will be more and more widely, and the use of network transformer will be more and more widely. The upcoming 3G communication market will be an important part of the information industry strongly supported by the state in the future.

In addition, the future development of mobile TV will also be a huge application market of communication network transformer. According to a report of IMS research, by 2011, due to the promotion of broadcasting services such as DVB-H, nearly 500 million users around the world will watch mobile live TV programs. By 2010, mobile digital TV will grow at an annual rate of 50%.

The production of magnetic ring coil has been mostly manual. Since China has changed from labor-intensive to technology-intensive, many industries have tasted the sweetness in the field of science and technology, which has affected the transformation of many companies. The manual labor of processing magnetic ring coil with manual and hook needle makes them miserable, unstable quality, low production capacity, low efficiency, difficult to recruit workers, high labor price The processing profit is low, especially the micro magnetic ring. At present, the rent of factories in the Pearl River Delta is expensive, it is difficult to recruit employees and there are many logistics problems. Basically, no such processing factories can survive. All of them are relocated to the mainland, which has disconnected the product chain here and seriously affected the production of many factories.

For large magnetic rings, many factories use manpower to complete orders. However, now the demand for small magnetic ring coils is large, and manpower can not meet the market demand. The need for small magnetic ring full-automatic winding machines is becoming louder and louder.
