Manufacturing method of RFID label

Abstract

The invention provides a manufacturing method of an RFID label, wherein the manufacturing method comprises the following steps of preparing materials; preparing a substrate which is provided with a first surface and a second surface that face each other; performing color printing on the first surface of the substrate for forming a colorful printed layer; material feeding, namely applying a catalyst ink on partial area of the second surface of the substrate for forming an ink layer with a specific pattern; chemical plating, namely dipping the substrate into a chemical plating trough for performing chemical film plating on the ink layer on the substrate and forming an RFID antenna which is made of copper metal on the ink layer; wafer plating, namely arranging a wafer at a preset position on the second surface of the substrate; and forming an obstructing layer, namely adhering a piece of release paper with the second surface of the substrate for covering the RFID antenna and the wafer, thereby forming the RFID label, simplifying a manufacturing process and saving cost. According to the manufacturing method of the RFID label, adhesion of the RFID antenna on a film and adhesion between the film and the substrate are not required. A required shape circuit can be formed just throgh directly performing chemical plating a film on the substrate, thereby realizing high convenience.

Description

technical field [0001] The invention relates to a method for manufacturing an RFID tag. Background technique [0002] In the known manufacturing of RFID tags, the RFID antenna and chip are first formed on a film, and then the film is pasted on a substrate. The process is complicated and time-consuming, and the cost is further increased. [0003] In addition, most RFID antennas are wrapped with metal wires and fixed on the film, which is quite expensive and has extremely low production efficiency, and it is difficult to produce lines with finer outlines. [0004] In view of this, how to produce RFID tags with relatively simple process steps, and how to improve the quality of RFID antenna lines while increasing production efficiency and reducing costs have become issues that people in the industry want to solve urgently. Contents of the invention [0005] The main purpose of the present invention is to provide a method for manufacturing an RFID tag, which has relatively sim...
