Abstract
The utility model discloses a twin-core radio frequency identification (RFID) tag, which comprises a base material, two chips fixed on the base material and UHF antenna; wherein, the conduction pins of the chips are connected with the UHF antenna which belongs to aluminum film antenna, the conduction pins of the chips are bound connected with the UHF antenna through aluminum wire, the two chips fixed on the base material implement multi-criteria communication protocols on a RFID tag. The conduction pins of the chips are connected with the aluminum antenna through aluminum wire, in which way the electric property is far better than the art of flip chip, the electric resistance is slight and the sensitivity is raised deeply. The chip bonding pad produced by the art of aluminum wire binding needs not to be plated and be block up. The utility model has the advantages of sparing expensive imported equipment processing and cost greatly.
Description
Technical field
The utility model belongs to RFID (radio-frequency (RF) identification) field, particularly a kind of twin-core UHF electronic tag.
Background technology
The UHF electronic tag, also be radio-frequency (RF) tag, as data carrier, it can be by the noncontact space induction mode of uhf band, with read write line dual-mode antenna and relevant application software formation rfid system, be widely used in data identification, item tracking and the message identification etc. in industry, commerce, office and management automation field.Existing UHF electronic tag comprises base material, is fixed on chip and UHF (ultrahigh frequency) antenna on the base material, and this electronic tag mostly is the chip of simple grain, and a kind of chip can only be supported a kind of consensus standard, and purposes is single; This UHF antenna generally is to make by conductive silver paste, because the resistivity of conductive silver paste is bigger, causes the Q value of UHF antenna lower, and the sensitivity of electronic tag decreases; Simultaneously, this UHF antenna is carrying out chip nation regularly, must adopt " flip-chip " (Flip chip) technology, and the conductive pin dish of chip must be given prominence to by bed hedgehopping, and protuberate must adopt craft of gilding, thereby cost can be in any more.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of multi-usage, highly sensitive and twin-core UHF electronic tag that cost is low.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of twin-core UHF electronic tag, comprise base material, be fixed on chip piece and UHF antenna on the base material, the conductive pin of chip is connected with the UHF antenna, also include second chip block, the UHF antenna is an aluminium film antenna, and the conductive pin of chip is connected by aluminum steel nation surely with the UHF antenna.
The beneficial effects of the utility model are: base material is provided with the chip of two different models, can realize the communications protocol of many standards on an electronic tag; The conductive pin of chip directly is connected with aluminium film antenna with aluminum steel, and its electric conductivity is good more than " flip-chip " technology, and its conductive resistance rate is very little, and sensitivity improves greatly; Adopting aluminum steel nation to decide the chip bonding pad of technology simultaneously need not gold-plated and bed hedgehopping, import equipment processing that also need not be expensive, thereby cost reduces a lot.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing of I among Fig. 1;
Fig. 3 is that the A-A of Fig. 2 is to cut-open view.
Embodiment
Referring to figs. 1 through Fig. 3, a kind of twin-core UHF electronic tag, comprise base material, be fixed with chip 1 and 2 and UHF aluminium film antenna 3 on the base material respectively, chip 1 is connected with UHF aluminium film antenna 3 by aluminum steel 4 respectively with 2 conductive pin, antenna nation fixed point 5 on aluminum steel 4 one ends and the UHF aluminium film antenna 3 is fixing, and the pad nation fixed point 6 on an end and chip 1 or 2 is fixing; Two chips can be realized good resonance coupling with aluminium film antenna 3, need not to increase separately impedance matching circuit, such UHF twin-core sheet electronic tag just can be realized the function of two kinds of consensus standards, as specific embodiment, the thickness of described UHF antenna 3 is not more than 0.035mm, its length is not more than 74mm, width is not more than 42mm, wiring width is not more than 0.8mm, the coupling live width is not more than 3mm, line mouth spacing is not more than 0.55mm, chip 1 and 2 can adopt UCODE HSL and two kinds of U frequency ranges of UCODE EPC G2 Intelligent Recognition IC chip of PHILIPS Co. respectively, the conductive pin of chip directly is connected with UHF aluminium film antenna 3 with aluminum steel 4, its electric conductivity is good more than " flip-chip " technology, its conductive resistance rate is very little, sensitivity improves greatly, adopt aluminum steel nation to decide technology simultaneously, one side is less demanding to chip, pad need not gold-plated and bed hedgehopping, can reduce the cost of raw material, also needn't adopt expensive " flip-chip " equipment and " anisotropic conducting rubber " also more expensive to process on the other hand, thereby cost reduce a lot than gold.
Have, described chip 1 and 2 is fixed on the base material by fixing glue-line 11 again, and its physical stability is wanted firmly than " flip-chip " technology, avoids loosening even come off and influence being electrically connected between conductive pin and the UHF antenna 3 because of chip.
In addition; described base material comprises from top to bottom the strippable paper layer 9 and the double-sided adhesive layer 10 of bonding successively; the UV that UHF antenna 3, chip 1,2 and conductive pin thereof are wrapped in behind ultraviolet lighting protects in the glue 7; UV glue layer 7 surfaces are pasted with copperplate protection sheet 8; electronic tag just has the flexibility characteristics of similar papery like this; the bend resistance ability improves greatly, is suitable for using on the article of glass, plastics and different field such as wooden.
Above-mentioned just the utility model preferred embodiment but should not constitute restriction of the present utility model, so long as adopt the technical scheme that is equal to the utility model, and also should be within the protection domain of the invention.
