Description

Connection structure between RFID chip and antenna

[ technical field ] A

[ background ] A method for producing a semiconductor device

The electronic tag is also called as a radio frequency tag, a transponder and a data carrier; the reader is also called a reading device, a scanner, a reading head, a communicator, a reader-writer (depending on whether the electronic tag can wirelessly rewrite data). The electronic tag and the reader realize space (non-contact) coupling of radio frequency signals through a coupling element; and in the coupling channel, energy transfer and data exchange are realized according to a time sequence relation. Conventional electronic tags include an RFID chip including an RFID radio frequency part and an ultra-thin antenna loop, and are widely used in clothing, shoes, vehicles, containers, and the like.

At present, the antenna is generally obtained by etching and printing conductive paste, and then the RFID chip is directly adhered to the antenna by using the anisotropic conductive adhesive, so that the electrical connection between the RFID chip and the antenna is realized, and the external communication (transmission and reception of electromagnetic waves) is realized. The RFID tag is simple to process and low in cost, and is the mainstream processing mode at present. However, in some application occasions, the requirement for the RFID tag to bear external pressure, especially shear force, is relatively high, while the current anisotropic conductive adhesive is epoxy glue, which has relatively high self-rigidity and good performance in coping with pressure, but is slightly insufficient in coping with shear force, for example, when the RFID tag is wound around a shaft with a relatively small diameter, the rigid conductive adhesive is separated from the antenna, when the RFID chip is applied to clothing such as clothes and shoes, because the material of the clothing can be bent at will, the electronic tag using the RFID chip as a main body is inevitably bent in the process of using and transporting the clothing, and when the current electronic tag is bent, the main body of the RFID chip and the antenna are easily fixed and are not firm, and contact is poor, thereby affecting the use of the electronic tag.
