Abstract
The utility model discloses an ultra-thin bending-resistant electronic tag card, comprising a surface material layer, a middle material layer, a core material layer, another middle material layer and another surface material layer which are sequentially laminated from top to bottom. The core material layer consists of a base material, an antenna coil and a chip, the antenna coil and the chip are disposed on the base material, and the chip is reversely packaged on the antenna coil by conductive adhesive. The reverse packaging technology is adopted, accordingly, the thickness of the card is reduced, bending resistance is improved, and possibility of artificial damage is reduced.
Description
Technical field
The utility model belongs to the REID field, is specifically related to the curved electronic tag card of a kind of ultra-thin folding.
Background technology
Radio RF recognition technology (Radio Frequency Idenfication; RFID) be a kind of non-contacting automatic identification technology; Through radiofrequency signal recognition objective object and obtain related data; Identification work need not manual intervention, and as the wireless version of bar code, the RFID technology has the not available waterproof of bar code, antimagnetic, high temperature resistant, long service life, read that distance is big, data can encrypt, store that data capacity is bigger, the canned data change waits advantage freely on the label.Its ultimate principle is to utilize the transport property of radiofrequency signal and space coupling (inductance or EM coupling) or radar reflection, realizes being identified the automatic identification of object.
Rfid system comprises electronic tag and reader two parts at least.Electronic tag is the data carrier of radio-frequency recognition system, and electronic tag is made up of label antenna and label special chip.RFID reader (read write line) carries out radio communication through antenna and RFID electronic tag, can realize reading or write operation tag recognition sign indicating number and internal storage data.
RF identification has been applied to aspect of social life such as ticket management, traffic dispersion, intelligent logistics at present.Because itself, the quantity of electronic tag is far longer than the quantity of reader, and it also is the electronic tag card that people contact maximum in life.In the modern society, almost everybody has card: mass transit card, bank card, medical card or the like or the like are difficult to imagine how the society that does not block us can be.
Along with the development of society, the various cards of holding in people's hand are more and more, and Ka Bao is more and more thicker, so people have higher requirement to the portability of card.And present electronic tag cartoon Chang Yinwei technology and the deficiency that designs cause the thickness of card can not satisfy the requirement of people in modern to its portability.On the other hand, because the thickness problem of present card, its suppleness also is affected, usually all can be harder, thereby the performance of anti-folding bending resistance shortcoming to some extent just, thereby also remote effect the serviceable life of card.
The formation of common passive RF product is with after antenna (Antenna) is connected by chip (Chip); The answering circuit that forms claims to reply film (Transponder INLAY); Characteristic is on thin base material, to adhere to, the about 0.08mm of base material thickness, and chip and antenna all have certain thickness; And the thickness requirement of super-thin electronic label is between 0.5 ~ 0.6mm; And the thickness of chip and antenna has just accounted for most, and the thickness of leaving plane materiel for is just very limited, and this has just limited the further attenuate of electronic tag card.
Along with the popularization and application of RFID technology in urban public tranlport system and entrance managing system, contact type intelligent card is just towards miniaturization, portable, trend development cheaply.
The utility model content
To above-mentioned deficiency of the prior art, the utility model proposes the curved electronic tag card of a kind of ultra-thin folding, with solve now existing electronic tag card thickness excessive, under the situation of stressed bending flimsy problem.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
The electronic tag card is bent in a kind of ultra-thin folding; Form by precoat laminated together successively from top to bottom, the middle bed of material, core material layer, the middle bed of material and precoat; Described core material layer comprises base material and is located at aerial coil and the chip on the base material; It is characterized in that said chip is encapsulated on the aerial coil through conducting resinl.
Said pin of chip is connected with antenna through the conducting particles in the conductive glue.
The thickness of said precoat is 0.08 ~ 0.12mm.
The thickness of the bed of material is 0.08 ~ 0.12mm in said.
The thickness of the base material of said core material layer is 0.05 ~ 0.08mm.
Than the positive encapsulation technology of tradition; The encapsulation technology of falling that the utility model adopted makes the utility model need on base material, not punch; Need not connect chip and antenna, formed bag when therefore yet just having avoided use glue to encase chip through the mode of routing; Because chip and the antenna of the utility model is extremely thin, this just greatly reduces owing to the thickness that Chip Packaging caused again, thus the electronic tag card of the utility model can do thinner.
The utility model is owing to adopt encapsulation technology; Existing relatively electronic tag the core of the card sheet position is difficult to confirm; Can produce thinness is required harsh card, the curved torsional resistance of folding significantly improves, and has reduced the possibility of artificial damage; And significantly improved production efficiency, reduced production cost.

Embodiment
In order to make the utility model clearer, the utility model is further specified below in conjunction with specific embodiment and accompanying drawing.
Embodiment:
The electronic tag card is bent in a kind of ultra-thin folding of the utility model as shown in Figure 1, is made up of precoat laminated together successively from top to bottom 100, the middle bed of material 200, core material layer 300, the middle bed of material 200 and precoat 100; Precoat 100 is processed by PET or PVC, and its thickness is 0.1mm, and the middle bed of material 200 is processed by PVC, and its thickness is 0.1mm.
Like Fig. 2, shown in Figure 3, core material layer 300 comprise base material 310 and the aerial coil 320 and chip 330 be located on the base material, base material is processed by PET, thickness is 0.06mm.
As shown in Figure 4, chip 330 is encapsulated on the aerial coil 320 through conducting resinl 340.
Conductive glue contains conducting particles, vertically be connected thereby pin of chip captures one to two conducting particles with antenna, thereby and in the horizontal each conducting particles be dispersed in do not contact mutually in the glue non-conductive.
The nude film reverse packaging process of the utility model has solved well in traditional binding technology that module thickness is thicker, and problem such as lamination is frangible has well improved the goods yield; Simultaneously, because of etching antenna and the reduction of nude film thickness, present card can be accomplished the thickness less than 0.5mm; Compare the card body of traditional 0.8mm; Reduced by about 42% PVC/PET material, only do not reduced cost, from the angle of environmental protection; Also reduce the use of plastic, protected our environment as much as possible.
The foregoing description be interpreted as only being used to the utility model is described and be not used in the restriction the utility model protection domain.After the content of having read the utility model record, those skilled in the art can do various changes or modification to the utility model, and these equivalences change and modification falls into the utility model claim institute restricted portion equally.
