Radio frequency identification chip and manufacturing method thereof

Abstract

The invention discloses a radio frequency identification chip and a manufacturing method thereof. The manufacturing method of the radio frequency identification chip comprises the steps that base materials are selected to form a base material layer of the radio frequency identification chip, conductive ink is printed on the base material layer to form an antenna pattern, the antenna pattern is electrically connected with an integrated circuit chip correspondingly to form a chip antenna layer of the radio frequency identification chip, and the chip antenna layer is coated with a layer of film to form a film layer of the radio frequency identification chip. According to the radio frequency identification chip and the manufacturing method thereof, complexity of the manufacturing technique of the RFID chip is reduced, manufacturing time of finished products is shortened, and manufacturing cost is reduced.

Description

technical field [0001] The invention belongs to the field of packaging, in particular to a radio frequency identification chip and a manufacturing method of the radio frequency identification chip. Background technique [0002] The entire supply chain of consumer goods from manufacturing to retail requires authentication technology. Traditional authentication technologies that rely on barcodes or 2D barcodes are low-cost but easy to counterfeit. [0003] Radio Frequency Identification (RFID) technology can automatically identify target objects and obtain relevant data through radio frequency signals, so RFID technology has been widely used. With the widespread application of RFID chips, the market demand for RFID chips is increasing. [0004] As for the RFID chip, its antenna greatly affects the performance of the RFID chip, so the manufacture of the antenna is a key link in the process of making the RFID chip. At present, the manufacturing methods of antennas are mainly e...
