Shenzhen cichuang Communication Technology Co., Ltd. is a local enterprise that designs and manufactures network communication components and modules. 70% of its business comes from network communication transformers. Other products include filters, ADSL voice separators and interface modules, which are mainly used for network communication equipment such as network cards, switches, routers, SDH / PDH, DSLAM and so on. Over the past four years, cichuang's revenue has increased by 50 ~ 60% every year, the company's employees have surged to 1100, the total output of various product modules has reached 3 million per month, and created its own brand "ppt".

Seize market space with low price and close service

Before 1999, local enterprises were basically blank in the field of network transformer, filter and interface module. Since providing network communication transformer to Shida computer, cichuang has entered the market at a price 30 ~ 40% lower than that of its peers, and continues to absorb the advanced technology and manufacturing technology of foreign component suppliers in Chinese manufacturing plants, so as to continue to grow. It is the company like cichuang that makes the local procurement proportion of Chinese OEMs in network communication components increase year by year (cichuang believes that the proportion has reached 70 ~ 80%).

On the premise that the product function and performance reach the same foreign products, proximity service is an important weapon for local companies to win the market, and cichuang is no exception. Zhou Daowen, general manager of cichuang, said: "today, when customer needs are changing faster and more diverse, cichuang provides technical and business communication much faster. For example, we can provide application samples within one week, while it takes 2-3 months abroad." cichuang's production bases are located in Shenzhen, Huizhou and Jingzhou, Hubei, and in Beijing, Shanghai, Chengdu Wuhan has branches or offices. Zhou Daowen said: "setting up factories in the mainland can reduce production costs, so as to ensure that PPT products have more competitive advantages in the market. Quality assurance and technical support are also localized. Professional FAE can also help customers solve problems in product design, which is not done by other peers."

Continue to invest in R & D and accelerate product upgrading

The development of the enterprise depends not only on the market and management, but also on the continuous R & D of new products and technologies. Therefore, cichuang invests 5% of its sales revenue in R & D, testing and adding testing equipment every year. Zhou Daowen said: "our core technical team is very stable. In the four-year development process, we have also learned a lot of process and technical experience from foreign peers, as well as technicians from pulse, midcom and other large international companies. The gap between technology and international level has been narrowed."

"We want to develop the market by adding new products and high-end products," Zhou said. Cichuang has invested millions of yuan to develop a series of integrated RJ45 magnetic element connector modules, integrating transformer, filter, EMI elimination device and RJ45 port. It is mainly used for network products such as network switch and hub. The channel specification is 2 × X(2 × 4，2 × 6，2 × 8) , it has reached the mass production capacity of 50000 pieces per month. For the latest model 2 × Li Tingchen, chief engineer of cichuang, an 8-port connector module, said: "it not only has higher integration, greatly saves assembly space, but also saves PCB area, and the assembly is relatively simple. The product conforms to IEEE802.3 standard, adopts iron shell shape design, and has the characteristics of better shielding effect and good anti-interference (EMI) effect."

Magnetogen is also very strict in magnetic material selection and electromechanical combination design. Because the communication network transformer plays an important role in signal transmission, the magnetic material generally selects the material with fast frequency response speed and high permeability to meet the requirements of high efficiency, low loss, low temperature rise and fast response speed of network communication. Manganese zinc (MnZn) ferrite and nickel zinc (NiZn) ferrite materials are mostly used for high-frequency and power supply equipment, while the high-frequency network transformer with particularly high requirements for anti-interference and magnetic permeability will use the super microcrystalline material with high price.

On the other hand, Li Tingchen believes that the miniaturization, planarization, functional diversification and superior performance of the whole electronic product also promote the development of network magnetic devices towards miniaturization, lightness, high electrical performance and high reliability. However, the combination of machinery and electronics has brought about a sharp increase in the technical difficulty of product integration, especially in the case of high requirements for anti electromagnetic interference, the technical challenge of mechanical structural parts is very great. Therefore, it is often necessary to open the mold in Taiwan or abroad, and it is often necessary to work closely with the mold supplier to design together to make the structure more suitable for assembly and mass production.

Cichuang also invested a lot in automatic process equipment, using automatic tin dipping equipment and winding equipment to save labor costs, reduce manufacturing costs, and ensure product consistency and high reliability.

Strengthen R & D cooperation with chip manufacturers

Although cichuang now has large customers such as Lenovo, Foxconn, Panasonic, Shida, Wuhan Fenghuo and Sichuan Maipu, they are not satisfied with the impressive achievements of the domestic market, but focus on the international market. In June this year, the company sent people to the United States for investigation. The purpose of this move is to prepare to add a sales department or office in the United States, and to strengthen cooperation with foreign chip manufacturers in R & D.

Zhou Daowen said, "the characteristics of the industry determine that we must follow up and carry out research and development of new products in combination with the chip characteristics of chip manufacturers." as the foreign IC industry is relatively mature, chip manufacturers can easily design Transformer Models of foreign brands when providing network card, ADSL modem and switch solutions, Therefore, the market opportunities of Chinese mainland enterprises are still in the stage of replacing foreign brands. Cichuang said that it can now be compatible with a variety of models of products of delta, pulse, Bel and other brands, but hopes to enter the U.S. market and carry out in-depth cooperation with chip manufacturers in R & D.

The cooperation between the two will make the manufacturers of network communication components gain a lot, which can mainly form a binding effect. With the overall solution of IC manufacturers being promoted to the application end of customers, it will achieve the brand promotion effect, and improve customers' awareness and trust of the brand products. At the same time, it can also greatly improve the compatibility and performance of products, get rid of the limitation of design on finished chips, and understand the market demand and follow up the latest technology at the fastest speed, so as to greatly shorten the time to market. "Our advantage also lies in participating in the supporting design of chip manufacturers. We have participated in the cooperation of Raycom, ZTE, Ruiyu, Marvell and other chip manufacturers in the design and R & D of new products. In particular, we have carried out in-depth cooperation with Ruiyu in the newly developed network card and ADSL chip." Zhou Daowen added.
