Problems solved by technology

It can be seen from the above that the cost of aluminum etching antenna is high, the process is complicated, and the thickness of the antenna is relatively thick. More importantly, the etching and cleaning process in the production process will produce a large amount of waste metal solution pollutants

Embodiment Construction

[0010] Further illustrate the present invention in conjunction with accompanying drawing and example, figure 1 It is an electronic label made by the invention. Among them, the antenna 2 of the electronic tag uses silver paste conductive ink to print the antenna pattern on the substrate through a large roller printing machine. The substrate of this example is paper. The silver paste conductive ink model is PGI-722, and the thickness of the paper is 0.12 mm, the thickness of the silver paste conductive ink antenna is 0.002mm, which is almost negligible.

[0011] Conductive ink is a special ink, which can add conductive carrier to UV ink, flexographic water-based ink or special offset printing ink to make the ink conductive. Conductive ink is mainly composed of conductive fillers (mainly metal powders, metal oxides, non-metallic powders and other composite powders), linking agents (mainly synthetic resins, photosensitive resins, low melting point plexiglass, etc.), additives (ma...

Abstract

The invention relates to an application of conductive ink in an electronic tag antenna, belonging to the technical field of an electronic tag. Based on improvement in the structure and manufacturing of the existing electronic tag antenna, the application is mainly characterized in that an antenna pattern is printed on a substrate through a large roller printing machine with silver paste conductive ink, the silver paste conductive ink mainly comprises ultra-fine silver powder, is liquid thermosetting ink and has the characteristics of strong adhesion, low temperature curing, controllable conductivity, low resistance and the like, and the electronic tag antenna can be manufactured in a printing process, the film printed with the silver paste conductive ink is thin, uniform and smooth and has an excellent performance. The production cost is greatly reduced, the manufacturing process of the electronic tag antenna is simplified, the production efficiency is increased, the total thickness of the antenna is only one sixth of that of an aluminum etched antenna, and the applications of the manufactured electronic tag can be expanded due to the low cost and thin film.

Description

technical field [0001] The invention relates to the application of a conductive ink in an electronic tag antenna. In modern society, the electronic tag greatly facilitates people's management of items, and is the main component of the Internet of Things. At present, the application of electronic tags is very extensive, including library collection management system, package management system, passenger ticket, luggage, vehicle toll management system and so on. The electronic tag antenna is an important part of the electronic tag and belongs to the field of electronic tag technology Background technique [0002] At present, the antenna of similar electronic tags at home and abroad uses aluminum etching technology to directly etch the antenna pattern. The structure of the aluminum etching antenna is the antenna pattern of aluminum foil laminated on the polyester PET plastic film substrate. The thickness of the polyester PET plastic film is 50um, the thickness of the aluminum ...
