Example Embodiment

[0021] The present invention will be further explained below in conjunction with the drawings:

[0022] Such as Figure 1-3 As shown, a marking method for defective radio frequency tags is characterized by including the following operation steps:

[0023] (1) Preliminary testing of electronic radio frequency tags;

[0024] (2) Through the detection of step (1), screen out weak or unqualified products;

[0025] (3) Conduct conductive ink jet printing at the core position of the weak standard product or unqualified product in step (2) to form aed short-circuit path;

[0026] (4) The use of conductive materials to greatly reduce the resistance between the two contacts of the chip or the two contacts of the antenna at the corresponding position of the chip, making the weak-label RFID a defective product;

[0027] (5) In the next step of the preparation process, RFID can be judged to be defective through electrical test judgment, human visual inspection, sensor recognition or machine vision ...

Abstract

The invention discloses a marking method for defective products of radio frequency tags, and belongs to the technical field of manufacturing of electronic tags. Electric conducting ink is adopted to replace general black or red non-electric conducting ink; a printing position is changed to the outer periphery of a chip, so that two electrodes of a traditional core directly penetrate through the electric conducting ink to cause short circuit; a to d points of a traditional circuit only can pass through a b c d paths out of the chip; and a e d short-circuit paths are formed after jet printing of the electric conducting ink. As circuits at two ends of the chip generate short circuit, the traditional matching impedance amplitude of RFID Tag is reduced, the RFID Tag is failed, traditional weak marked products change to definite defective products, and are only judged as the defective products but not good products, the leaving of the weak marked defective products to customers can be effectively prevented, the operation steps are simple, the working principle is clear, the defective electronic tag positioning precision is improved, the output of the weak marked products is effectively prevented, and the operation speed and the production efficiency of electronic tags are further enhanced.

Description

technical field [0001] The invention belongs to the technical field of electronic label manufacturing, and relates to a label marking method, in particular to a marking method for defective radio frequency labels. Background technique [0002] RFID tags are widely used in logistics, drug supervision, public service, animal husbandry, etc. due to their advantages such as large storage data capacity, long reading distance, encryption of data on the tag, and free change of stored information. Moreover, its reliable anti-counterfeiting and fast reading are also decisive factors for its gradual replacement of barcodes. In actual production, when a defective product (weak label) is found, it is necessary to accurately locate the defective product and mark it. However, it is very difficult for the current RFID technology to achieve accurate positioning in the production of small-pitch multi-row and multi-column labels. . [0003] There are three types of existing RFID Dry inlay d...
