High temperature resistant RFID electronic tag and preparation method thereof

Abstract

The invention provides a high temperature resistant RFID electronic tag and a preparation method thereof. The RFID electronic tag cooperates with a reader-writer to work, and at least comprises a tag antenna and a tag chip, wherein the tag chip is integrated with a master controller as well as an antenna RF circuit and a memory which are connected with the master controller; the tag chip is protected by adopting a secondary package to form an SMD package structure; the substrate in the antenna is a high temperature resistant ceramic antenna substrate, and silver coating layers are arranged on both the positive and negative surfaces of the ceramic antenna substrate; the tag antenna is welded and fixed on the ceramic antenna substrate; and a sealed casing is sleeved outside the RFID electronic tag, the casing is made of a high temperature resistant PPS material, and a high temperature resistant pouring sealant is filled in the casing. The product provided by the invention can withstand cooking at the temperature as high as 150 degrees centigrade and the negative pressure cooling, and can be widely applied to various industrial production lines, medical disinfection and other application environments.

Description

technical field [0001] The invention provides a high-temperature-resistant RFID electronic tag and a preparation method thereof. The tag can withstand high-temperature cooking at a temperature as high as 150° C. and is cooled by negative pressure, and belongs to the technical field of RFID electronic tags. Background technique [0002] RFID electronic tags are the physical carrier of product electronic codes (EPC). High-temperature tags are attached to items to be tracked and can be identified, read and written. Currently, they are widely used in the fields of logistics and process control. In the application of industrial production line and medical disinfection, the label will encounter high temperature and high humidity application environment. Ordinary electronic tags cannot withstand the harsh production environment, and cannot be effectively used in production line and medical disinfection control systems. Contents of the invention [0003] The invention provides a h...
