Passive ceramic substrate-based electronic label special for automobile and manufacturing method thereof

Abstract

The invention discloses a manufacturing method of an electronic label, which comprises the following steps of: forming latticed groove lines with a broken memory function on a soft blank material used for manufacturing a ceramic substrate by pressing a die, wherein the ceramic substrate is provided with a printed circuit etching surface and a label pasting surface; pre-firing the soft blank material having the latticed groove lines at a low temperature; firing the blank material to form the ceramic substrate at a high temperature; and laying circuits and components on the ceramic substrate. The electronic label manufactured by the method comprises the ceramic substrate with the printed circuit etching surface and the label pasting surface, the latticed groove lines which are arranged at the at least one surface of the ceramic substrate and have the broken memory function and the printed circuit attached to the ceramic substrate. The passive ceramic substrate-based electronic label special for the automobile can effectively prevent non-designated holders from removing and reusing the label to ensure the unique correspondence between the automobile and the electronic label. In addition, the electronic label can be equivalently broken together with the windshield in the state of automobile accidents and cannot cause secondary injury to the drivers and the passengers.

Description

technical field [0001] The invention relates to a radio frequency identification, in particular to a passive ceramic-based electronic tag for automobiles and a manufacturing method thereof. Background technique [0002] With the promotion and development of RFID application technology, various types of electronic tags working in the UHF frequency band are increasingly used in the field of automobile road traffic. There are increasing application demands to solve the unique correspondence between electronic tags and marked objects, anti-disassembly and reusability, and the protection of personal safety of electronic tags during use. [0003] In the application of vehicle management, the unique correspondence between the electronic tag and the marked vehicle and the anti-dismantling and multiplexing, and the electronic tag fragments will not cause secondary damage to the driver and passengers when the vehicle is in an accident state, gradually become RFID technology. Importan...

AI Technical Summary

Problems solved by technology

It is very likely that the electronic tag will be completely dismantled and misappropriated to other vehicles. It is difficult to guarantee the unique correspondence between the tag and the marked vehicle, which will cause loopholes in the supervision of vehicles.

[0007] 2. After the ceramic substrate is broken under a certain external force, it will form extremely irregular sharp fragments

Therefore, when a vehicle accident occurs, the ceramic label installed on the front windshield of the car is very likely to pose a threat to the personal safety of drivers and passengers due to broken
