Abstract
A production method for electronic label recognizable by radio frequency is capable of making electronic label of multi-rings antenna on one plane, so to simplify the production procedure and decrease the cost.
Description
Technical field
The invention belongs to field of radio frequency identification, be specifically related to a kind of method that is used to make radio frequency recognizing electronic label.
Background technology
Typical radio frequency recognizing electronic label comprises the antenna that an individual pen closure or multi-turn closed circuit form, and at least one integrated circuit (IC) chip that is connected to antenna ends.Its with read write line between to communicate by letter be untouchable, realize by radiofrequency signal.The radiofrequency signal frequency range for example comprises 1: the low frequency frequency is at 30kHz-300kHz, and typical frequency of operation has: 125kHz, 133kHz.2: the high frequency frequency is at 3MHz-30MHz, and typical frequency of operation is 13.56MHz.3: the ultrahigh frequency frequency is greater than 400MHz, and the exemplary operation frequency is 915MHz, 2.45GHz, 5.8GHz, etc.
The classical production process of radio frequency recognizing electronic label as shown in Figure 1, be generally lead or conductive metal foil that insulation course will be arranged and on non-conductive substrate 4, coil curl formation antenna 1, antenna one end connects the integrated circuit (IC) chip 2 that back-off, the other end passes through (or perforation is passed through from B.B.P) from the non-conducting material 3 that covers on the antenna, and integrated circuit (IC) chip is linked back.Fig. 2 is the sectional view of classical production process.Fig. 3 is the integrated circuit (IC) chip synoptic diagram, and wherein antenna ends is connected (two pads can also can be with on two positions in the chip same point on one side or not on the chip diagonal line) respectively with pad 2 with integrated circuit (IC) chip pad 1.The label antenna two ends of welding chip are not conducting on electrical property.
The shortcoming of above-mentioned manufacture method is if adopt the individual pen antenna, can be on same plane with the antenna of radio frequency recognizing electronic label and chip manufacturing, but the efficient of accepting radio-frequency (RF) energy owing to the radio frequency recognizing electronic label of individual pen antenna is very low, and it is near that the electronic tag operating distance can become.And in order to make the multi-turn antenna, antenna connects back chip in manufacturing process needs to put up a bridge or bore a hole on the substrate material by non-conducting material, thereby increased the complexity of technology, increased the manufacturing time of radio electronic label, improved the manufacturing cost of radio electronic label.
Summary of the invention
The invention provides a kind of improved method that is used to make radio frequency recognizing electronic label.By this method, can make radio frequency recognizing electronic label on same plane, thereby simplify the manufacturing process of radio frequency recognizing electronic label with multi-turn antenna, reduce the manufacturing cost of radio frequency recognizing electronic label.
The present invention relates to two aspects to the improvement of original radio frequency recognizing electronic label method for making, on the one hand, the integrated circuit (IC) chip pad location mode and the connected mode that are used for making radio frequency recognizing electronic label are improved, (N is an integer to increase the N bar in chip, N＞0) (two pads can be also can be with on two positions in the chip same point on one side or not on the chip diagonal line to have the conductive channel (6) of two pads (5), material in the conductive channel can be metal or other conductive material), (N=2 among Fig. 4) as shown in Figure 4; On the other hand, make and to improve being produced on frequency identification electronic label antenna on the substrate, the antenna after the improvement no longer is continuous conducting, but is divided into discrete N+1 section, (N=2 among Fig. 5) as shown in Figure 5.In manufacturing process, integrated circuit (IC) chip back-off encapsulation (or other feasible packing forms) is being manufactured with on the substrate of antenna, there is pad that conductive channel connects that 2 * (N+1) individual Interface Matching of N+1 section antenna on 2 * (N+1) individual pads and the substrate altogether are packaged together in original two pads of chip add, so just the discrete antenna segment of N+1 section on the substrate connected into the antenna loop of a closure by the conductive channel of chip internal.
The pad at described conductive channel two ends is on the chip diagonal line or with on one side or not in chip on two of same point positions; Two pads are on the two ends of conductive channel or the passage not on two positions in same point.
Described conductive channel is shaped as straight line, broken line or curve.
Described antenna be shaped as sheet, tabular, paper tinsel shape or spiral helicine electric conductor.
By said method, just can realize in a plane that the radio frequency recognizing electronic label of multi-turn antenna is made, thereby reduce manufacturing process, reduce manufacturing cost.

Specific embodiment
The invention is further illustrated by the following examples.
Embodiment: Figure 7 shows that improved radio frequency recognizing electronic label synoptic diagram with two circle antennas, in this embodiment, the antenna (9) that is produced on the non-conductive substrate (10) is two sections not conducting metal wires mutually, and 4 soldering openings are arranged, the pad that has conductive channel to connect in the integrated circuit (IC) chip (9) is diagonal angle row portion, add original two pads, also one have 4 pads, be encapsulated in the integrated circuit (IC) chip back-off on the substrate and make its pad corresponding with the soldering opening of antenna, antenna is closed in two traps that just antenna of two sections mutual not conductings can be connected into a conducting.So just can produce the radio frequency recognizing electronic label that has two circle antennas.
