Forming method of electronic tag

Abstract

A forming method of an electronic tag comprises the steps of forming a carrier plate comprising a first area and a second area; forming a radio frequency identification antenna comprising a first end and a second end on the first area, wherein the first end extends outwards to the second end in a spiral ring shape, and the radio frequency identification antenna is provided with an opening for disconnecting each spiral ring; forming a first metal connection wire across the surface of the first area and the surface of the second area, wherein the first metal connection wire penetrates through the opening and is electrically connected with the first end; forming a second metal connection wire electrically connected with the second end; forming a plurality of third metal connection wires at the opening by adopting the lead bonding technology and electrically connecting every two opposite cross sections of each spiral ring disconnected by opening; providing a radio frequency integrated chip comprising a first interface and a second interface, electrically connecting the first interface with the first metal connection wire and electrically connecting the second interface with the second metal connection wire. The electronic tap occupies small areas.

Description

technical field [0001] The invention relates to radio frequency identification technology, in particular to a method for forming an electronic label. Background technique [0002] RFID (Radio Frequency Identification: Radio Frequency Identification) is a non-contact automatic identification technology, which automatically identifies the target object and obtains relevant data through radio frequency signals. It does not have the advantages of waterproof, high temperature resistance, long service life, large reading distance, data on the label can be encrypted, storage data capacity is larger, and storage information can be changed freely. Its application will bring revolutionary changes to industries such as retail and logistics. . [0003] The basic RFID system consists of a reader (Reader) and an electronic tag (or transponder, Transponder). Among them, the electronic tag (Tag): consists of a radio frequency identification antenna and a radio frequency integrated chip. Ea...
