Paste a paragraph of the domestic industry RFID industry research articles to you:
With the wide application of RFID technology, especially contactless bus cards, campus cards and other projects around the promotion, training a number of chips, packaging, read-write terminals and system integration vendors. These domestic manufacturers have mastered the mature technology, the initial formation of the domestic RFID industry chain.
RFID industry chain is mainly composed of the following parts: standardization, chip design, tag packaging (including antenna design), identification system design and production, system integration and management software development. The following is an introduction to the current situation of the RFID industry chain at home and abroad from these aspects.
(1) standardization due to the early development of 13.56MHz RFID technology, the relevant standards are also more mature, the main international standards are ISO/IEC14443 and ISO/IEC 15693 two, the domestic 13.56MHz RFID standards are also mainly derived from these two international standards. In the typical applications introduced above, China's second-generation resident ID card is based on ISO/IEC 14443-B standard; public transportation cards and campus cards are mainly based on ISO/IEC 14443-A standard. There are relatively few applications based on ISO/IEC 15693 standard in China, and typical applications include the Ministry of Education's student ticketing discount card.
Relatively 13.56MHz RFID international standards are mature and widely used, UHF, microwave band RFID is not yet a clear unified international standards. But in recent years, RFID technology leading countries and regions have significantly increased investment in the development of standards, are actively developing their own standards.
At present, there are three main foreign standards are being developed: ISO/IEC 18000 standards, the United States EPC Global standards and Japan's ubiquitous center (Ubiquitous ID) standards. These standards (organizations) are actively entering China, the establishment of agencies in the country, the network of their respective business interests, all hope to be able to influence the domestic UHF band RFID standard development, for the future in the vast Chinese market competition, to win the first opportunity on the standard.
In China, the relevant government departments have fully recognized the importance of the RFID industry, and for the development of industrial standards are increasingly important. In early 2004, the National Standardization Administration Committee set up a national standard working group for electronic tags in China, the purpose of which is to establish China's own RFID standards and promote China's own RFID industry. However, the process of developing national standards has had many twists and turns, and at the end of 2004, for various reasons, the National Standard Working Group on Electronic Tags was suspended.
But the development of national standards for electronic tags did not stop there. Although about the national standard still exists a variety of different voices, but compatible with international standards, support for independent intellectual property rights, the protection of China's interests in the advocacy of a wide range of **** knowledge. At present, the Ministry of Information Industry, the Science and Technology Commission, the National Standardization Committee and other 14 ministries and commissions have completed the preparation of "China RFID White Paper" to support China's own intellectual property rights of RFID coding system - the establishment of the NPC system. At present, the new RFID national standards drafting group has been established, and by the Ministry of Information Industry, the Director of the Product Division as the head of the drafting group and has launched the corresponding standard drafting work. The new standard will have independent intellectual property rights on the premise of seeking compatibility with international standards. It is reported that China's own RFID specifications are expected to be formally introduced in 2007.
(2) Chip Design Although in the RFID chip design, the domestic chip companies started late, but with the domestic chip design industry in the last 10 years, narrowing the gap with the international chip design level, the domestic companies in the RFID chip design on the opportunity to catch up with, or even exceed the technical level of foreign chip companies. At present, the main domestic RFID chip manufacturers are concentrated in Beijing and Shanghai, the representative companies are:
Beijing: China Power Huada Electronic Design Co. completely mastered the 13.56MHz RFID chip design technology, and can provide the corresponding read-write machine chip. In the domestic bus card, campus card and other 13.56MHz RFID market, Fudan Microelectronics, Shanghai Huahong and other companies have launched a series of mature RFID products, and in the equal competition with large foreign companies to achieve more and more market share.
In the UHF and higher frequency band RFID chip design, the domestic chip manufacturers are highly concerned about, but the strategy is different. Some manufacturers are in the wait-and-see stage, some manufacturers have entered or ready to enter the development of UHF band RFID chips. Fudan Microelectronics has been developed in 2004 to support the EPC Class0 standard products, the end of 2005 will be launched to support the ISO18000-6B standard products.
(3) tag packaging (including antenna design)
In the country, as the application of RFID is still mainly in the form of cards (such as China's second-generation resident identity cards, bus cards, etc.), after years of development, RFID card form of packaging technology has been very mature. Card form of RFID packaging mainly includes module packaging (chip assembly), card manufacturing (antenna production) and printing of the three main links, the current domestic in all aspects of the process have a large number of manufacturers, on behalf of the enterprises are:
Module Packaging: Shanghai Changfeng Smartcard Company, Shanghai Inol Information Technology Company Limited, China Smartcard Limited Liability Company, Shandong Shandong Mountain Aluminum Electronic Technology Co. Ltd.
Card production: Mobitai Peace Smartcard Company Limited, Beijing Zhong'ante Technology Co. Ltd., Shenzhen Yi Neng Da Smart Card Manufacturing Co.
Printing: Shanghai Toppan Printing Co., Ltd, Shanghai Printing Three, many card manufacturers
Currently, the card form of encapsulation in the country is still based on the traditional wire bonding (Wire Bonding) module encapsulation and wire-wound card technology. But with the thin card, self-adhesive electronic tags and other new packaging forms of RFID applications demand gradually warmed up, Flip Chip (Flip Chip), printing antennas and other new packaging technology has been the rapid development of some of the vendors have been able to provide the relevant packaging services, the new form of packaging has entered into practical applications, such as: Shanghai Railway Transportation one-way card (waveform card), Shanghai Fireworks management electronic tags (self-adhesive tags) and so on.
With the development of new packaging technology, RFID packaging technology has also appeared on the new processing links, such as flip chip bump generation (Bumping), antenna printing. Representatives of the enterprise are:
Bumping: Jiangsu Changdian Technology Company Limited, Hoplon Technology (Hangzhou) Co.
Antenna printing: Shenzhen Huayang Microelectronics Co., Ltd, Huangshi Jiede Wanda Gold Card Co.
While in the country already has a mature card form RFID packaging technology, new packaging technology in this year has also had a rapid development, but overall in the advanced packaging technology with a large gap with foreign countries, do not have the ability to package low-cost RFID products. With the development and application of RFID technology, packaging has presented more and more challenges, such as: chip assembly technology how to get smaller and smaller chips reliable assembly. How to significantly improve the speed of packaging to adapt to the explosive demand. How to further reduce the cost of packaging and so on. At present, many domestic visionary packaging plant is preparing to introduce foreign production technology, in order to take the lead in the future competition on the RFID package.
(4) recognition system design and production of the current domestic 13.56MHz RFID recognition system (card reader) design and production of mature technology, with a large number of manufacturers and products, with strong competitiveness; in contrast, in the UHF band on the manufacturers, products are not much, the technical strength and the gap between foreign manufacturers. On behalf of the enterprises are:
13.56MHz RFID identification system: Shenzhen Minghua Aohan Technology Co, Shanghai Qiangsheng Technology Development Company, Harbin New Zhongxin Electronics Co., Ltd., Guangdong Sanjiu Wisdom Electronics Co. ......
UHF RFID identification system: Shenzhen Yuanwanggu Information Technology Co.
(5) system integration and system software development and identification system design and production The same, 13.56MHz and UHF band RFID system integration also shows a large imbalance: 13.56MHz RFID system integration technology is mature, there are many vendors; UHF RFID system integration vendors are not many, and there is a certain gap between the technical strength and foreign manufacturers. Representatives of the enterprises are:
13.56MHz RFID system integration: Shanghai Huateng Software System, Zhuhai Yida Technology Electronic Industry Co. UHF RFID system integration: Beijing Weishen Electronic Technology Co., Ltd, Harbin Wake Technology Co. The relationship between RFID can be successfully promoted the key links, but also the future of the RFID industry value chain on the highest section. Compared with the efforts of large foreign software companies to develop RFID system software, domestic software companies are relatively rarely involved in the development of RFID system software, in this regard, the domestic capacity and foreign countries are very different.
In fact, RFID manufacturers in the country too much too much, and the good and bad, the best way, you put forward the needs of natural people to give you professional advice. Welcome to the RFID information network forum (/bbs) to ask questions
