Problems solved by technology

[0007] The above-mentioned conductive sheet is usually called a carrier. The chip is placed on this carrier and then riveted to the wire end. This process is purely because the original chip manufacturer is an expedient measure for the expensive flip-packaging equipment in the early stage, because the contact surface is too large to cause the label to be damaged. The bending characteristics are very poor, and it is easy to cause the carrier and the coil to separate during use, which not only has high cost but also low yield
[0008] In actual use, users often need the thinner the electronic tag, the better, but this kind of electronic tag that uses a copper-clad plate to make the antenna, because the conductive sheet is used to connect the wire end of the antenna to make the bridge part of the antenna, the conductive sheet It itself wil

Description

technical field [0001] The invention relates to the technical field of electronic tags, in particular to a method for manufacturing a radio frequency antenna by using a resin single panel, and a radio frequency antenna and an electronic tag manufactured by using a resin single panel. Background technique [0002] With the rapid development of automatic identification technology, the application of electronic tags using radio frequency identification (Radio Frequency Identification, RFID) technology has become more and more extensive, in logistics and non-contact integrated circuit (Integrated Circuit, IC) cards, etc. all play an important role. [0003] Any electronic tag includes the RF antenna part and the RF IC chip part connected to the RF antenna. There are many ways to make the RF antenna, such as using copper clad plate, enameled wire winding, and screen printing. [0004] Among them, using copper-clad boards to make radio-frequency antennas is a relatively common ma...
