RFID technology is one of the current hot topics. For example, the labels used in smart packaging airports or libraries used in the pharmaceutical industry, and the labels used in logistics and supply chain have all adopted or are preparing to adopt RFID technology. What does this growing new thing mean for label printing companies? There is no doubt that RFID tags have brought new opportunities for label printing companies, but there are still some misunderstandings in the RFID industry. How should label printing companies correctly understand and get involved in RFID technology? This article will tell you the answer.
RFID tag production
The following is a brief introduction to some actual situations in the production of RFID tags. After RFID chips are produced and transported as semiconductor silicon wafers, these chips are sent to embedded processors for processing, so that the chips can meet the technical requirements of being embedded as tags. The chip will be connected with the integrated circuit and antenna. This automatic pick and place process is completed by the robot in an absolutely dust-free environment. The completion of the inlay marks the end of the preparation work for the RFID core components. Next, the label printing company can sandwich the inlay between the label substrates like a sandwich, so that a complete RFID tag is completed.
Each chip has a certain storage space. At the beginning, no data is written until the inlay and substrate are made. The label printing company or end user can write relevant information into the chip. Since the automatic pick-and-place process requires an absolutely dust-free working environment, it is quite difficult for label printing companies to process inline. Of course, if the dust-free working environment cannot be guaranteed, it can also be done by printing the antenna: install a ribbon-shaped connection pad on the online production line to print the antenna. Industry experts believe that. Printed antenna is a very promising technology.
The design and manufacture of the antenna can be done by etching copper wire, or it can be printed with conductive ink. In order to improve the performance of the antenna and reduce the impact of metal or liquid products on the label reading rate, some major RFID manufacturers have standardized the antenna design. It is speculated that printing the antenna with conductive ink will be a very important way to reduce the cost of RFID tags, but it may take several years for the technology to mature.
There are several major challenges in the production of high-quality RFID tags. Some problems existed even before the tags began production (the most prominent is the chip problem). Label printing companies believe that there are two main problems in the production stage of RFID tags. : Static electricity problems and label testing problems.
Misunderstandings in the RFID industry
There are many opinions about RFID, and sometimes it is difficult to tell the truth. Listed below are some common misunderstandings that currently exist in the industry, let us analyze together.
Myth 1: RFlD tags are of very poor quality
About two years ago, the pass rate of RFID tags was almost 50%. This number frightened many label printing companies. Although the unqualified rate of RFID tags is still 20%, experts from Avery Dennison believe that the quality of RFID tags is indeed constantly improving and improving, and we should be more patient with them. At present, all kinds of universal tags we use have also reached the current level after many years of development. It will take some time for RFID tags to be recognized by people. Moreover, because of the addition of the chip, the RFID tag has become a very delicate and complex communication device, so it is not realistic to expect the RFID tag to reach a fairly high application performance immediately.
Although RFID is not a new technology, it is still used for the first time on many occasions, and it takes a certain amount of time to write the operation guide, so it is not surprising that it takes months or even years. The use of UHF RFID tags in the supply chain has only been in the last 2 to 4 years.
Misunderstanding 2: Wal-Mart makes great contributions
When Wal-Mart asked its suppliers to adopt RFID technology at the end of 2003, everyone thought that the top 100 suppliers would definitely do their best to meet the requirements of this retail giant. Although more than 100 suppliers have successively adopted RFID technology The pace and magnitude are not as fast as one might expect. These suppliers certainly attach great importance to Wal-Mart ’s requirements, but they have adopted a more conservative and cautious approach in their actions, waiting for technological progress and maturity, as well as the introduction of new EPC standards.
