Abstract

The invention relates to a manufacturing technology of a chip-free RFID label, which comprises the steps of printing an antenna and a resonance circuit pattern on a piece of transfer paper; transferring a conductive metal onto a base material surface through vacuum vaporization method; transferring the printing of the antenna and the resonance circuit pattern on the transfer paper onto the base material surface; drying the base material with the antenna and the resonance circuit pattern; washing the conductive metal on the base material apart from the antenna and the resonance circuit pattern through a solvent; washing a printing layer on the base material surface apart from the antenna and the resonance circuit pattern through a washing lotion until the antenna and the resonance circuit are fully exposed; and plane polishing and levelling the exposed antenna, removing chips and overlaying film for packaging to obtain a chip-free RFID label. According to the manufacturing technology of the chip-free RFID label, the RFID label cost is greatly reduced; a chip-free RFID label can be obtained; advantages like excellent flexibility resistance and good toughness, low manufacturing cost and simple and good operation technology are provided; and wide application prospect is provided.

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...
