The invention relates to a manufacturing process of a chipless RFID label, comprising: printing an antenna and a resonant circuit pattern on a transfer paper; using a vacuum evaporation method to transfer a conductive metal to the surface of a substrate; using a thermal transfer method to transfer The pattern of the antenna and resonant circuit on the printed paper is transferred to the surface of the substrate; the substrate printed with the antenna and resonant circuit pattern is dried; the conductive metal on the part other than the antenna and resonant circuit pattern on the substrate is washed away by solvent ; wash off the printed layer on the surface of the base material with the antenna and the resonant circuit pattern until the antenna and the resonant circuit are completely exposed; carry out plane polishing and leveling treatment on the exposed antenna, remove debris, and then cover the film to obtain a flawless Chip RFID tags. The manufacturing process of the chipless RFID tag of the present invention greatly reduces the cost of the RFID tag, and can produce the chipless RFID tag, which has the advantages of excellent folding resistance and good toughness, low manufacturing cost, and simple and easy operation process. with broadly application foreground.
Description
technical field [0001] The invention relates to the technical field of radio frequency identification, in particular to a manufacturing process of a chipless RFID tag. Background technique [0002] Radio frequency identification technology is an automatic identification technology that uses radio frequency signals to carry out two-way information transmission through space coupling. It is a non-contact automatic identification technology. It can automatically identify the target object to obtain data through radio frequency signals. It does not require manual intervention to identify dog legs. It has the advantages of anti-magnetic, waterproof, high temperature resistance, and large storage data capacity. It can be widely used for example. Non-stop charging system, train transportation monitoring system, commodity five logistics management, assembly line manufacturing automation, access control security management, animal husbandry management and other application fields t...
