Embodiment Construction

[0025] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0026] Such as figure 1 Shown, a kind of manufacturing method of RFID etching aluminum antenna, comprises the following steps: 1. Aluminum foil is laminated with polyester PET plastic film; 2. Use cleaning solution to carry out surface treatment to composite aluminum foil; 3. Use ink to print ; 4. Carrying out chemical etching on the laminated synthetic aluminum foil; 5. Removing the ink on the surface of the etched aluminum antenna.

[0027] The basic material of the antenna is aluminum foil. The impurity content, material, thickness, and surface state of the aluminum foil will directly affect the quality of the product. Therefore, in order to achieve the performance index of the antenna, the aluminum content of the aluminum foil described in ...

Abstract

The invention provides a method for making a main part of antenna for radio frequency identification (RFID) of a tag, aiming to make an aluminum etched antenna which is good in electrical property, low in pollution and price, large in productivity and thin in thickness. The method for making the aluminum etched antenna comprises the following steps of: combining aluminum foil with polyster PET plastic film; 2. treating the surface of the combined composite aluminum foil with a washing solution; 3. printing with printing ink; 4. performing chemical etching on the combined composite aluminum foil; 5. removing the printing ink on the surface of the aluminum antenna after etching. The method for making a RFID etched aluminum antenna of the invention adopts the printing ink with special components, which almost prevents the environment pollution during the etching process, thereby the printing ink on the surface of the antenna after etching is easy to remove, various difficult factors in the production are overcome. The invention contributes greatly to the popularization and application of the RFID technology.

Description

technical field [0001] The invention relates to a method for manufacturing an antenna, the main part of a radio frequency identification tag. Background technique [0002] Radio Frequency Identification (RFID) technology is rapidly penetrating into every field of human life in the 21st century. As the appearance of products that have been applied, they are mainly divided into two categories. The first category is cards, which are mainly used for people management, such as various access control management, membership management, bus cards, ID cards, etc. The second category is paper labels, which are mainly used in the management of people and objects. The number of applications in this form will soon be an astronomical figure as technology continues to advance. [0003] In summary, the various applications of RFID tags are inseparable from the core part of the tag - electronic components, commonly known as "INLAYS" in English, and "core layer" in Chinese here. INLAY's man...
