Under "Prosperity"  scene over the years, China's manufacturing internal began to experience thoroughly remould oneself type transformation and reconstruction, is the industrial upgrading CCTV news mentioned, especially in recent years, as China's demographic dividend has disappeared, the foreign manufacturing industry is gradually transferred to southeast Asia and India, Brazil, Mexico, etc. in countries with lower labor costs; Especially after Trump took office, western developed countries also proposed the concept of returning to manufacturing. Today, we see the "high-end can not maintain, low-end difficult to maintain" dilemma, it is the transition of the inevitable chaos and the necessary training; China's manufacturing industry has a lot of pain to go through before it can reinvent itself. I have been lucky enough to work in the connector industry for more than 20 years, and I am very proud of this trend. Finally, I have moved away from the so-called "low tech" industry and have been able to sell backboards, IO, cables and consumer electronics (TB3; TB4, USB3.1 USB 3.2 or USB 40G, HDMI 2.1...).But this boom may only last for a very short time. In a few years' time, new companies will join. What kind of expertise will these new companies have?

Understand the market, service cable connector industry

In a market economy, the market is an indicator of enterprise, is the decisive factors in enterprise resource configuration. Understanding of market research is the premise of enterprise management. In the past, our connector in foundry industry, generic primarily, because of the weak awareness of market research and combined with the government's lack of service consciousness, to the market data squeamish, his mouth shut. As the countries in transition, industrial upgrading is burning, choice is manufacturing research and development and innovation, the state under the situation need to be in this year will have to start the implementation of strategy of big data, market information will be more detailed, accurate and open. Organize the connector industry research of market information, to produce on a regular basis Connector industry market information data, the previous annual/quarter sales and data, change the connector industry in various fields, such as cars, computers and peripheral, mobile phones, industrial) market scale, structure and increase the data, the connector in the emerging industry of market data. In addition to also want to do a good job in the development of the downstream industry trends and new technologies will be gestated by the new market research. These data information is of the essential for the healthy development of the enterprise business and industry for a long time. Provide the connector industry market information, to guide the healthy development of industry, service connector industry, realize manufacturing value-chain, power connector industry upgrading.

We will strengthen R&D and innovation, and establish independent intellectual property rights and industry standards.

Past domestic connector industry mainly OEM, imitation, innovation is weak, independent intellectual property rights and industry standard is impossible. Some improvement in recent years, such as domestic individual connector manufacturers involved in the cable and connector specifications > < USB Type C, a handful of American firms become the market leader; Only a few domestic manufacturers participate in the market, connector industry should strengthen the following aspects of R&D innovation.

☞Patent works; Faced with a mountain of patent problems;

☞Signal characteristic analysis team;

☞Equipment and test engineering;

☞Institutional design team;

☞Precision mold design team;

☞Manufacturing and maintenance teams;

Automatic assembly and test equipment team of full servo system;

Innovation, diligence, Careful consideration, perseverance

Connector applications are becoming more and more widespread, so how to ensure that connector can work in extremely harsh environment? Many foreign connector senior experts point out that, at present, China's production of consumer electronic connectors, low-end connector capacity is very strong, Very competitive, mainly because of this kind of connector application environment is moderate, product life requirement is not high, the product reliability requirement is not high also, easy to copy. They think China once I start production conditions, high life, high reliability requirements of the connector, the lack of basic research connector problems will be exposed, before one of the few problems will occur frequently, under a lot of challenges. The western theory of connector expert thinks, not master the connector/data interface theory, do not understand the failure mechanism, the connector will not be able to scientific evaluate the reliability of the connector. High reliability of the connector (cars, war industry, industry, etc.. Domain product) and produce tiny positive forces connector will encounter big obstacle: either because they do not understand and evaluation is not sufficient, or too conservative cause too much waste and not competitive. We only strengthening the basic application research of the electrical contact, strengthen the research possible innovation connector interface products, set up reasonable discipline, competitive independent intellectual property rights and industry specifications.

Large current transmission technology. The connector inevitably applied to transport large current occasion. Large current transmission technology is mainly two directions: reduce the generation of joule heat/reduce resistance and increase the cooling capacity. In addition to guarantee the reasonable structure of the interface, we need to study to meet other performance requirements on the basis of how to improve the conductivity of the terminal materials and thermal conductivity, and to increase the size of terminals, how to make the terminal section flattening, how to make the terminal as much as possible when it is exposed to the air (increase the requirement of interface stability) to the requirement of interface stability, how to use less plastic (need to have enough support intensity) and lower the height of the plastic. How to test the connector of the current-carrying Capability is also controversial in the industry. How to apply the simulation technology to the development of high-current connector needs to be studied.

High frequency signal transmission technology at a high speed. The founder of Intel Moore puts forward very famous Moore's law, an integrated circuit can accommodate the number of components, about every 18 - 24 months will be doubled, the performance will be doubled. This law reveals the speed of information technology. Even though this trend has been going on for more than half a century, information technology or keep high speed development - the equivalent of the components of the transmission speed of information technology progress is endless. Connector transmission speed won't be able to avoid increasing demands, and it is a requirement in electronic miniaturization, "light" "thin" before Way, which greatly improved the technical difficulties of high frequency high speed connector. So import high frequency high speed simulation means to assist the connector design is also a common practice. The connector after miniaturization of high-speed transmission space is limited, in order to improve the high-speed transmission performance (such as adjusting the characteristic impedance and reduce the crosstalk between signal), the development and utilization of low dielectric constant of plastic material, or as much as possible by air medium is very important, which requires strength and thin wall molding plastic material have enough support ability/liquidity. The USB type. The high frequency and high speed transmission performance test of the connector is inseparable from the test board, and the research and development of the high frequency and high speed test board is also an important part of the connector research and development.

Mechanical simulation method application in the connector industry. In under the trend of miniaturization of electronic products, coupled with the high frequency performance requirements of high speed transmission and transmission power requirements, the connector how to use limited space and optimize the structure to achieve the corresponding mechanical strength and mechanical property requirements become increasingly complex, for example, as the terminal miniaturization, in order to improve the positive force of terminal, blanking of the blade used for separation of interface will be more and more common, apparently, the surface of the blanking die cutting and rolling plate surface conditions are very different, how to evaluate these two kinds of the influence of different surface conditions on mechanical properties of terminal is unable to avoid. Application of mechanical simulation method has become a connector is common practice to develop. With the ascension of high nonlinear simulation of plastic forming technology, mechanical simulation will be more widely used in the field of production technology, such as used for analysis of the terminal bending forming spring back amount, such as analysis of deep drawing seamless metal case again, hollow tube, hollow and forming conditions and forming ability help enhance the level of the design of the mould and reduce test, die-die even avoid change of work.

Connector materials research and development. It has talked about material how to influence the performance of the products. We consider, in fact, the performance of the products is determined by the structure of the products and materials. When the miniaturization and the simulation method is widely used, driven by the product of the limited space to limit will be used, or the product structure is optimized to the limit, in this case the performance of the product competition is the competition, the material is the importance of materials research. Especially in recent years the rise of nanotechnology, nanotechnology can significantly change the material microstructure, significantly improve the performance of the material. 2014 IEEE website published two new kinds of plating, nanocrystalline silver tungsten Palladium alloy and silver alloy, these two kinds of alloy compared with silver, and the hardness and environmental stability/corrosion resistant ability is greatly improved, so relative to the current connector interface, silver plated coating can significantly reduce wear and insert force, the stability of interface in the bad environment and high temperature resistant performance will improve a lot. Many occasions to replace gold plated layer. These new materials/coating undoubtedly enriched connector interface design technology also provide more choices for the connector interface design. The article also reported that Tyco electronics has turned the coating is applied to many different areas of the connector.

The development of connector product standards. Compared with other components, connector's dependence on product standards is more superficial -- without product standards, it is impossible to guarantee the cooperation of male and female connectors, and the connector cannot work at all! Is one of the development trend of modern electronic products standards, integrated, systematic. The components of the product standards is often mentioned to develop system level, this approach is conducive to industrial vertical integration. The content of the standard is often take the form of communication protocol. The connector was promoted to a higher level of standardization, necessary to standardize the connector interlock, the content of the standard becomes complex, this will greatly increase the difficulty of the standards: participate in standardization organizations (including the connector manufacturer) more, there are more industries, such as IC industry; More downstream industries, such as PCBA; More standards participants benefit gambling, such as standard for the requirements of the product's performance level, the ownership of the new standard of patent and standard reference existing patent license and fee. Standards become more complicated, density and technology content is higher, and the market requirement standards cycle or update cycle shorter, so the communication technology is widely used - conference calls and email greatly accelerate the development process of the standard. The standard setting process and system to adjust, VITA (VME Industry Trade Association) recently changed its policy on patents.

Connector production technology, the miniaturization of the distance between the center of the terminal (pitch), currently on the market there have been a 0.2 pitch FPC connector. Foreign connector technology roadmap (roadmapping) pointed out that in 2020 a 0.1 pitch connector, believe that will bring profound changes of connector manufacturing technology, actually connector manufacturing technology in recent years has begun to experience great changes,0.2 pitch connector some have begun to break through the traditional production technology - instead of stamping/molding, terminal or stamping mold some start with ceramic material. Plastic thin-wall molding are also facing a growing challenge. With the improving of the domestic labor costs, connector miniaturization brings to the manual assembly difficulty and the stability of product quality requirements, the connector manufacturing (packaging, assembly), application (welding plate, wiring) automation is necessary.

Industrial integration and optimization.

Just like the typical manufacturing industry, the connector industry is faced with the task of industrial upgrading. Domestic connector industry structure in various applications/proportion, / level/including the structure, industry characteristics, the distribution of the product line/capacity/technical ability, etc. On this basis, we guide the reasonable layout of connector industry. Through technology upgrading, professional collaboration, foster strengths and circumvent weaknesses, optimize the industrial structure, expand the proportion in the high-end market, guide the excess capacity. As with connector miniaturization, seamless deep drawing metal structure will be more and more common, so the appropriate corresponding joint related manufacturers, to strengthen the deep drawing technology, improve the level of specialization degree and the specialization of production, improve competitiveness in the international market. With tong the advance of technology, the popularity of Internet + application, the advent of the era of big data, market information is more and more developed, the market is more and more transparent. Combined with the country's new government to combat corruption and build a clean government, society will be more and more clear, the social environment is more and more fair. Believe that competition in connector industry competition is more and more technology, professional degree of competition!
