Problems solved by technology

[0005] The above-mentioned adhesive technology is used to protect the inlay of the circuit part inside the electronic label from the erosion of the external environment. Although the purpose of temporary sealing can be achieved, but because the adhesive part has a hidden connection seam, it will encounter organic solvents, high temperature and high pressure. , Mechanical bending and other effects are very easy to be dissolved, glued or cracked, the electronic label inlay is exposed and damaged, and the service life is relatively short

Embodiment Construction

[0022] In a preferred embodiment, the paste rubber material 111 is a silicone rubber compound, and the cut paste rubber material 111 is divided into upper and lower layers, and an electronic tag inlay 112 is sandwiched between them. Put the paste rubber 111 and the electronic label inlay 112 into the cavity of the lower mold 102, the edge of the paste rubber 111 is larger than the edge of the electronic label inlay 112, the temperature of the upper mold 101 and the lower mold 102 is 170°C to 190°C, and the molds are closed Post pressurized to 50kgf / cm 2 , exhaust after pressurization in place, enter the vulcanization time after the exhaust is completed, and open the mold after the vulcanization time is 10 minutes. The silicone rubber 113 has been vulcanized to form a whole that fully covers the internal electronic label inlay 112. The electronic tag inlay 112 inside the electronic tag 120 is a flexible circuit board, including a polyimide film 114 as a base material, an etched...

Abstract

The invention relates to an electronic tag and a production method thereof. The electronic tag is composed of an electronic tag inlay and an elastomer material integrally wrapping outside the electronic tag inlay, wherein the electronic tag is produced by adopting a hot compression molding packaging technology. The whole external of the electronic tag has no joints, therefore, an adhesive is not needed, the defects of debonding and cracking or adhesive invalidation and the like can be effectively avoided, and the service life of the electronic tag is prolonged.

Description

technical field [0001] The invention relates to an electronic tag, which belongs to the application field of radio frequency identification tags, and also relates to a manufacturing method of the electronic tag. Background technique [0002] The radio frequency identification technology can send the radio frequency signal through the reading and writing equipment, and the electronic tag sends out the information stored in the chip by virtue of the energy obtained by the induced current. The application fields of electronic tags include warehousing and logistics, identification, product anti-counterfeiting, manufacturing tracking management and a wide range of industries. Due to the complex environment in which electronic tags are applied, electronic tags require strong environmental tolerance and are not easily damaged in some applications. Applications such as: identification, tracking, and statistics of washing items in laundry; anti-counterfeiting of clothing brands; clo...
