Abstract

The invention discloses an RFID transponder coil and a production method thereof. The RFID transponder coil comprises a base plate and a conductive circuit, wherein the conductive circuit is printed on the surface of the base plate through toner in a core-shell structure, and the toner in the core-shell structure is produced by core-used adhesive resin, shell-used adhesive resin, a conductive additive, an anti-bonding agent, an emulsifier and the like. The production method includes designing a graph of the RFID transponder coil; placing a base plate sheet into a printer using the toner in the core-shell structure, printing the graph of the RFID transponder coil on the base plate sheet to obtain the base plate sheet on which at least one RFID transponder coil is arranged; and cutting the base plate sheet provided with the at least one RFID transponder coil to obtain the RFID transponder coil. The coil can achieve functions and can be produced flexibly and conveniently, the printing effect is good by using the production method, small-lot production can be achieved, and the operation is easy and simple.

Description

technical field [0001] The invention relates to a conductive coil and a manufacturing method thereof, in particular to an RFID transponder coil and a manufacturing method thereof. Background technique [0002] RFID (Radio Frequency Identification), also known as radio frequency identification, is a communication technology that can identify specific targets through radio signals and read and write related data without the need to establish mechanical or optical contact between the identification system and specific targets. A complete RFID system is composed of three parts: Reader, Tag, also known as Transponder, and application software system. The reader can be a reading or reading / writing device according to the structure and technology used, and it is the information control and processing center of the RFID system. The reader is usually composed of a coupling module, a transceiver module, a control module and an interface unit. The transponder is the information carri...
