Description of the Invention: [Technical Field] The present invention relates to a method for fabricating a radio frequency identification tag, in particular, directly forming a slotted antenna on a substrate having continuous conductive performance over the entire surface, which can greatly reduce manufacturing cost It is non-polluting, recyclable, and has significant advantages such as high gain antenna, strong reflectivity, high conductivity, etc. [Prior Art] Radio Frequency Identification (RFID), also known as electronic tag, is a way to identify and read and write specific targets by radio signals without establishing mechanical or optical contact between the identification system and a specific target. Communication technology for related data. The current passive RFID tag is the mainstream in the market because it has a low price and does not require a power supply. In application, the RFID tag internal identification chip receives electromagnetic waves from the RFID reader for driving, and when the tag receives enough signals, it can send data to the reader. These data include not only the ID number (global unique identification ID), but also data pre-existing in the EEPR0M in the tag. The application field of RFID technology is very extensive, and it can provide all-in-one automatic and convenient real-time monitoring system functions by combining the technology of 201032142 database management system, computer network and firewall. Such as bills and products anti-counterfeiting technology, ID card, pass, electronic toll collection system, logistics management, air baggage monitoring, production automation control, warehousing management, transportation monitoring, security control and medical management. As shown in Fig. 1, the conventional RF tag structure is manufactured by using an etching etching method, etc., and a conductive silver paste is provided on a plastic film or a paper substrate. The antenna, and then the identification of the crystal moon on the antenna, not only creates troublesome costs, but also the actual size of the conductive silver plastic antenna is quite limited. The surrounding plastic film or paper substrate has poor screen wall effect, so it is easy to be The interference of the metal background object and the moisture environment, the electrical influence of the radio frequency identification standard, 'the RFID reader is not correctly read, and the application range is relatively limited. In addition to this, its implementation has the following disadvantages: 1. High cost: all need to configure expensive equipment, equipment costs of tens of millions to 100 million yuan, to print or etch the antenna on plastic film or paper On the substrate. The high cost of consumables such as silver glue and the high pollution treatment costs caused by etching have resulted in high RF tag antenna production prices. 2. Low yield: printing materials such as silver sputter are granular structures, their conductivity is not as good as that of continuous conductors, and the printed antenna 201032142 is prone to breakage. The etching method causes poor and discontinuous conductivity of the antenna due to insufficient exposure or excessive exposure. 3. Low-electricity accuracy: the characteristics of the antenna such as the impedance of the antenna, due to the thickness of the silver paste, uneven etching, etc., resulting in uneven distribution of conductance and magnetic permeability, resulting in errors such as antenna frequency drift and impedance mismatch, resulting in accuracy. It is difficult to control and the failure rate increases. 4. Low durability: Silver-printed silver glue sticks. Corrosion of the etched lines, 皆 makes the RF tag inventory difficult and the operation time is not long. 5. High customization cost: In response to the customer's application of the characteristics of the target object, such as frequency drift, group resistance, etc., it is necessary to make a screen for silver printing or etching the antenna. After actual testing, the electrical deviation Quantity, re-produce the screen and then silver, etch, and test. Repeated trials and so on, the cost of customization is still high, and it is impossible to achieve the goal of single stocking and single stock. In view of the above, the inventors have made in-depth research and improvement on the above-mentioned deficiencies, and 10 methods for fabricating a wireless ray-receiving label, which mainly include: 1. selecting a substrate having continuous conduction properties over the entire surface. 2) Punching the substrate on the substrate and providing the identification chip to the 201032142 3. Processing the slotted antenna on the substrate; thereby reducing the manufacturing cost of the RFID tag and saving power, Energy-saving, non-polluting, recyclable, and has a remarkable surface gain antenna (Antenna Gain), strong yelection rate (Conductivity), and the surface of the substrate has good surface conductivity. It can also significantly reduce the electrical influence of the target and the environment 'on the RFID tag, so it is more suitable for the RFID tag application of 10 objects such as metal objects and water-conducting conductors. EMBODIMENT The constitution and other features of the present invention will be The detailed description of the embodiments with reference to the accompanying drawings will be understood and understood.

The antenna 丨2 is further provided with the identification wafer 2, and the preparation method is completely the same, and only the steps are different, so the details are not described herein again. Therefore, the aluminum foil, the enamel or the conductive metal material can be used as the base material l' direct flip chip and the slotted antenna 12 is formed into the radio frequency identification tag 10 by the die punching and laser cutting. The method is novel. It is feasible and feasible, the material and process have low error and high product yield; no need to configure high-cost silver printing machine or etching machine during manufacturing, low cost, energy saving, energy saving, pollution-free and recyclable.

This enables the use of radio frequency identification systems to reach farther distances (140%). In particular, as shown in FIG. 8, the present invention has a large-area screen wall effect due to the fabricated radio frequency identification tag 10, which can significantly reduce the target and environment during application, and the radio frequency identification tag 10 The electrical influence is therefore more suitable for radio frequency identification i 〇 label applications for metal objects or hydrated conductor targets for accurate reading by the RFID reader 3. 201032142 Further, the above-described process method of the present invention is not limited to the fabrication of a radio frequency identification tag, and the manufacturing technique can be applied to the flexible electronic circuit wire forming.
