The hierarchy that has printed element
The cross reference of related application
The application requires in the priority of the U.S. Provisional Patent Application the 60/670th, 076 of submission on April 11st, 2005.
Invention field
The present invention relates to have the thin, layered structure of built-in electric function, for example display and the correlation electron device that is used to drive this display.This display and/or other function element in this structure form by typography.
Background of invention
Plastic layer stacking industry relies on heat lamination technology manufacturing credit card, identification card, loyalty card and other contain the plane token of information.This technology is to have the laminated plastics sheet stacked combination that obtains finishing stacked together of the various functions such as opaque, figure and protective layer.Each layer can be opaque or transparent, and can contain the function element such as magnetic stripe.In case each layer of expectation is assembled, this assembly just experiences hot pressing each layer is fused together to form a continuous structure.As from most of leather wallets and wallet, showing, produced more than one hundred million cards and come dealing with various requirements.Providing of card do not charged separately in many cases, so that supplier can learn its cost.
Typical assembly is by central core, the preceding graph layer that is pre-printed usually and back graph layer, magnetic stripe and gloss is provided and protects the protective clear layer of printed pattern to form.Usually in this structure, also comprise safety function part such as hologram.Smart card is then by adding microprocessor and chip is made after stacked, wherein above-mentioned interpolation is by grinding a recess and the integrated chip plate being installed and integrated circuit is realized.IC can be attached to antenna when needed, can communicate by letter via RF in contactless mode to allow IC.The preferred material that is used for existing thermosphere stacking comprises the layer made from polyvinyl chloride (PVC), polypropylene, Merlon, polyester and fusion temperature other suitable plastic between 110 ℃ to 190 ℃.
The heat lamination technology that is used for fabrication has been represented the installation card production capacity of main flow in the global range.Developed other technologies such as relying on bonding cold stacked of adhesive, but these technologies only realize in limited scope also.If any new card structure can be compatible mutually just more useful with existing heat lamination technology.
The expectation attribute of institute's complete layer stacking comprises high glaze, distortionless figure and even level and smooth surface.In addition, for financial transaction card and identification card, this structure also must be according to the ISO standard.There is the iso standard at the outpost of the tax office to define various performance requirements, such as temperature and moistureproof ability, flexibility, stacked integrality, flatness and physical size.The range of application of identification card will determine the physical characteristic of card.The physical characteristic (ID-1, ID-2 and ID-3) of card is described in ISO/IEC 7810:2003 identification card-physical characteristic to some extent.The test of card to band magnetic stripe, integrated circuit or optical memory is described in ISO/IEC 10373 identification cards-method of testing to some extent.The requirement of contact in the integrated circuit card then is suitable for the integrated circuit card of ISO/IEC 7816-1 identification card-contact-carrying.The standard of relevant protruding lettering symbol is then in ISO/IEC 7811-1:2002 identification card-record technology-part 1: provide in the type.ISO 7813 has stated the requirement that the financial transaction calorie requirement reaches.And ISO/IEC 7501 is applicable to Machine Readable Travel Documents, such as passport and visa.Another kind of identification card is the flexible thin card (TFC) that is suitable for ISO/IEC 15457.Other relevant standards are explained in appendix A.All these standards all are incorporated in this as a reference.
Can when finishing, this heat lamination technology bring great difficulty at the electronic unit of incorporating into before the heat lamination such as integrated circuit (IC), antenna, battery, display, switch and other circuit.Main difficulty is that the various thermal conduction characteristic by the various height of different parts and institute's materials used is caused.Unless the problems referred to above are fully solved, otherwise to electronic unit place in it treat stacked each layer execution heat lamination technology will cause blemish, to unacceptable distortion of internal part or damage.
RFID antenna and their chip are incorporated the thermosphere stacking in advance into.The antenna of one of copper cash, etching metal or printed silver can be connected to small IC usually, and this small IC is provided as an insert and is sandwiched in this structure as discrete layer.Heat lamination technology produces acceptable result to RFID because IC can be limited in a less zone and antenna can be done very thin.Yet more complicated structure can be difficult to produce the result that can allow the people receive owing to quantity and the vision and the ISO quality standard big or small and that will reach of each parts.
Be used for the additive method that electronic unit is incorporated in the card is related to by the mechanical means formation cavity such as grinding.A kind of in these class methods grinds card nuclear core to produce a cavity that is used for holding electronic unit.After having placed each parts, just add perfusion fluid to unnecessary milling zone so that this structure flatten.This method is relatively slow, the production cost height, and need more manufacturing process than simple laminating method.
Several different methods has been proposed in order to realize meticulousr electronic unit is incorporated into the expectation of card structure.German with reference to Patentschrift DE 19923138 C1 and Offenlegungsschrift DE 10219306 A1 teachings a kind ofly to made up the method for the isolating construction that contains electronic unit subsequently by heat lamination with the loose film of each layer of fusion by utilizing therein.This method is owing to the intrinsic changeability of original material is difficult to a large amount of realize and also need in manufacture process realizing the result that expects than stacked much more additional step.Use separation structure that each electronic unit is installed and be not enough to provide high efficiency, low cost ground to incorporate the renewable product means of electronic unit in this method of adding discrete layer subsequently.
Prior art require to be used the film that has specific thicknesses, and the thickness of these films may be not accurately mate with the thickness of each parts.In order to prevent this problem, manufacturer just need specify component thickness to mate each available film.The result that regular meeting during the manufacturing changeability of parts and film does not cause because highly match time.At last, this method is attempted the changeability of compensation individual component and film, but it does not solve the problem that the changeability introduced when using a plurality of parts in hierarchy increases.Itself then needs to consider the tolerance of die separation and placement its manufacturing process.
An appointed thickness that critical aspects is a whole card of requirement of some iso standard.The gross thickness of the card of iso standard appointment is 0.030 ± 0.002 inch.Because the common 0.005 inch every layer thick two-layer graph layer of calorie requirement, common 0.002 inch thick protective clear layer is so only leave the electronics core layer that 0.016 to 0.020 thickness can be used for incorporating into the functional electric subassembly.
This requirement has proposed special challenge to incorporating battery in blocking into.Current pre-packaged battery structure be generally 0.012 to 0.016 inch thick, such residual thickness that leaves just is not enough to embed battery pack easily and provides enough opacities to hide these parts.In addition, existing pack technology can cause higher package dimension changeability, and this must be considered in lamination process.
Specify flexible iso standard also to propose special challenge to electronic unit being incorporated into card.Circuit level is an importance of required consideration when making flexible product.Lamination process must generate the structure that can minimize each parts upper stress.And in card, can comprise various electronic units, such as IC, antenna, switch, battery pack, magnetic stripe emulator and display.Every kind of parts all may have different thickness, size and flexible, but must be encapsulated in the card again and the entire card flexibility that obtains expecting in the electric integrated level that keeps electronic circuit.
Expect very much display is incorporated into as the part of some card Electronic Packaging.Traditional display technology is unsuitable for incorporating into the card in accordance with ISO.Existing display has many restrictions inherently.For integrated display successfully, preferred display should be flexible, uses lower power to minimize the demand to battery pack, can below 3V, work minimizing required electronic unit quantity, and can be stacked with current process heat.
So just need a kind of like this electronics nuclear cored structure that have the electronic unit that is associated and comprise display, this structure can and reach the iso standard of relevant financial transaction card and/or identification card by heat lamination.More specifically, the card producing method that pays card to the user by applied customization final graphics layer needs a kind of electronics nuclear cored structure that the function that satisfies consumer demand can be provided.

Detailed description of the present invention
Introduce
The invention provides a kind of by electronic unit is incorporated into can by existing technology easily the electronics nuclear cored structure of heat lamination overcome the solution of the various defectives of prior art.This structure comprises a kind of device, and this device comprises the electronic unit of a plurality of expectations, such as display, battery pack or other power supplys, integrated circuit, switch, magnetic stripe emulator, antenna, intelligent chip or other input equipments.This structure comprises uses the variation of each stacked resilient coating with each layer of bridge joint and compensating unit size.Also merge pack as the part of this core layer structure and use printed electronic circuit as the part of this electronics core layer to influence desired characteristics.
As mentioned above, can incorporate multiple parts into this structure.In a nonrestrictive execution mode, display can be included in this stratification structure.Yet those of ordinary skills should be realized that by the present invention and do not comprise display in a plurality of stratification structure applications that this provides.
Display unit can be used as the sub-assembly of the electronics nuclear cored structure that embeds electronic unit and can handle it by the conventional heat lamination technology of each layer with other and meets relevant iso standard.This display unit can form the focus of smart card, label or other thin type information display structures and contain various parts.Typical parts comprise the combination of IC, display, battery pack, switch, antenna and connecting circuit.
The required IC of a certain concrete electronics nuclear core depends on terminal applies.In some cases, the chip more than two or two is necessary for carrying out required function.First will generate and/or send data based on the outside input usually.For example, in a kind of card, microprocessor after the switch input on the card from then on based on pre-programmed algorithm generation Trading Authorization number.These data are sent to display driver chip subsequently, and this chip changes into display image with data flow.Alternatively, the radio frequency receiver circuit can or obtain signal and this signal is changed into data flow and offer display driving software from specific reader from broadcasts radio waves.In other cases, single chip can not only be used to generate necessary data but also can generate desired value by driving display.If display is positioned in this structure, then IC can be used for coming and reader communication by contact mat, RF image or magnetic stripe emulator.Electronics nuclear cored structure contains needs dynamic communication to the IC that blocks external equipment therein.
Challenge comes from the different parts in the structure with change in elevation, and any one parts is all because the fabrication tolerance of each parts and film and have space variance inherently.More specifically, the IC parts do not have perfect uniformity.The variation of IC height mainly contains two sources: the difference of die height and by being attached to the caused variation of substrate.The variation of die height is the result of tolerance during silicon wafer grinds and polishes.The height change that is caused by attached die becomes along with the method for being utilized.Under the situation of utilizing the wire-bonded technology, loop height and adhesive bonding method will be introduced variation.The flip-chip attachment method can change because of the variation of tube core projection and the joining technique that utilized.In the above two kinds of cases, the use of sealant all will provide significant extra the variation.The die height that is generally used for being attached to each parts is about 0.007 to 0.012 inch when no sealant.
The operable a kind of display that comprises the electrochemistry ink of the present invention discloses by in United States Patent (USP) 6.639.709 number and 6.744.549 number and U.S. Patent Publication the 2002/0171081st A1 number preceding, though scope of the present invention can also comprise other Display Techniques.Can generate each display by the conventional typography that some height change is introduced in meeting.Yet preferred display shows the significant advantage that is higher than other display technologies for this application.These advantages comprise flexibility, low-power requirements and the strong construction of standing heat lamination technology.The exemplary height of preferred display is about 0.006 inch (0.150mm).This height of display is understood slight modification by the variation of printing height and the height change of each individual components of display such as backboard film, tin indium oxide (ITO) header board film and adhesive seal pad.
Notice that this display can form with electrochemical particular ink printing.Except IC and some small-sized pad that is associated with IC and display and trace, other structures that are described on this each layer of making or assembling also can link together by laminating adhesive or the other materials of having used printing technology by printing process formation and each layer.Suitable printing process comprises screen printing, the amine benzene art of printing and intaglio art.Use these methods just can realize a large amount of, the High-efficient Production of this structure, and need not to make normally used clean of these functional structures and specific apparatus for forming thin film.That is to say, can realize to be worked into easily effective, the scalable production in enormous quantities of cost of the nuclear cored structure in the final card.

The battery pack that is suitable for using in smart card requires slim form factor.These battery pack are generally known in the art and common chemical property based on lithium technology or carbon zinc.An example of suitable pre-packaged lithium battery group can be buied from the Solicore company of Florida State Lakeland, and its Part No. is FP252903M002.Suitable pre-packaged battery pack based on the carbon zinc chemical property can be buied from the Thin Battery Technology of Ohio Cleveland, and its Part No. is 1-1-ZC.Other thin battery group technology also is known based on solid-state structure or other electro-chemical systems.Being used for power supply of the present invention can be made of main battery or secondary cell unit.Memory device such as ultracapacitor can be used for making up by reader and charging device.It is the electromotive forces with at least 1.5 volts, the capacity of at least 5 MAHs that the typical case who is used for the suitable power source of conventional IC and miscellaneous part requires, and to have maximum ga(u)ge be 0.016 " the nuclear cored structure.
Can incorporate electronics nuclear core of the present invention into as the battery pack that pre-packaged unit generates.The total thickness of the battery pack that generates is between 0.012 to 0.016 inch.The structure 100 between flexible substrate 150 and the flexible top flat 110 can be inserted or be embedded in to pre-packaged battery pack 190.Alternatively, the chemical constituent of battery pack 190 can comprise that conventional silk screen printing, the printing of amine benzene or intaglio are placed on the stepped construction 100 by each layer and the feature that deposition contains battery pack by various known printing technologies.
The energy of deriving from battery pack is the result of chemical reaction in the battery unit.The active volume of this battery pack and power supply greatly depends on the amount of the pack material that can be used for reacting.To a great extent, the volume that it can be regarded as material.Because Free Region is fixed mostly in card structure, so the expectation of maximum battery group material volume is corresponding to the expectation of maximization thickness.
Battery pack requires encapsulation to comprise pack material and to keep the electrolyte (may be subject to the influence of evaporation) of proper level.Under the situation with slim form factor battery pack insert structure 100, this encapsulation is the shape that encases the pre-packaged film of this material.The thickness of this encapsulating film is generally 0.003 to 0.005 inch, and changing into total battery pack thickness as the result of necessity encapsulation just is 0.006 to 0.010 inch.Be printed in battery pack 190 under the situation of structure 100, layer or film that utilization of the present invention contains electronics nuclear core encase this battery pack, rather than use conventional pack material.
In a kind of known battery pack printing process, as shown in figure 14, the parts of pre-packaged low profile flexible printed battery 301 comprise the watery electrolyte in printed anode 303, printed cathode 305, cathode collector 307, anode collector 308, separator 309 and the separator, and all these are included in the flexible thin pack shell 311.The cathode sets piece installing of carbon zinc battery unit comprises the manganese dioxide active material 305 of cathode collector 307 and electrolysis, and they are by minimum cracking or be not printed onto the cathode collector ink with having cracking and will adhere on the flexible sheets on it.Current-collector 307 uses template, silk screen or other suitable printing equipments to be deposited on the flexible sheets.The prescription of cathode collector ink can be to dispose the material of the electron transfer that interdischarge interval generates cathodic reduction from being enough to.In the carbon zinc battery unit of the manganese dioxide cathodes that uses electrolysis, cathode collector is carbon ink preferably.The gatherer of printing will experience suitable cured subsequently to guarantee enough oven dry and solvent evaporation.What as shown in figure 14, the known method of thin battery group printing still can cause accounting for battery pack thickness important proportion is encapsulation or shell 311.
In the present invention, the otherwise track that is used to examine cored structure is placed pack material during also being used in and setting up the nuclear cored structure.By using the encapsulating film that replaces pre-packaged battery pack among Figure 14 as the film of an electronics nuclear cored structure part, the whole nominal thickness that extra volume can be used for increasing battery capacity or reduces battery pack.An embodiment of the invention are to remove extra encapsulating film by at the rete assembly process pack material being built into electronics nuclear cored structure.
According to the present invention, battery pack can be printed and embed in the some steps between nuclear cored structure tectonic epochs.Figure 17 shows the constitution step 1710 to 1780 according to the embedded battery group of an execution mode shown in Figure 13.Method is in one embodiment utilized silk-screen printing technique.The first step comprises that generation is used for the current-collector of anode and negative electrode.Under the chemically treated situation of carbon zinc, cathode collector is made up of conductive carbon.Current-collector is printed on the layer 110 or 150.In step 1710, the current-collector that illustrates is printed in the basic unit 150.Anode collector is by suitable conductive coating or by using conductive foil to form.Between anode and the negative electrode and the interconnection circuit between each battery use the conductive silver ink to form in step 1720 and the printing of 1770 places, above-mentioned conductive silver ink is such as being the Spraylat XCM-015 that buys from the Spraylat company of New York Pelham.Subsequently at the height of step 1730 printed cathode material with coupling core layer 145.Form anode by placing material with the height that reaches core layer 145 at step 1740 place.In step 1750, use time resilient coating that core layer 145 is laminated to basic unit 150, followingly will make more detailed description to this time resilient coating.
To be placed on the nuclear in-core such as the electric parts of display unit 160 in step 1780, and between each electronic unit and battery pack, form electrical interconnection.If want, can increase battery capacity at the extra cathode material of step 1760 printing of this assembling.Extra cathode material should not surpass the thickness of core layer 130.In case printed the cathode height of expectation, core layer 130 just uses time resilient coating to be laminated to core layer 145.This technology is produced the printed battery that is included in the trap that is formed by each core layer effectively.This battery pack is by adding battery pack electrolyte and adding shim when needed and finish to the trap that forms.Electrolyte can inject by printing or non-printing process.Alternatively, can inject and have suitable viscous agent and make it be gelatinous water.In structure side by side, the moistening battery unit of spacer is also fixing in position electrolyte.In coplanar structure, separation function spare is not only fixed electrolyte in position but also anode and negative electrode can be separated.The pack material of placing is passed through the stacked and sealed of core layer 120 sealed cell unit subsequently.
Those of ordinary skills should be realized that the anode and the negative electrode that can use various battery unit geometries to form battery pack.It should further be appreciated that and in series to produce and to connect each battery unit to increase supply voltage.The variation of battery unit geometry can be produced the anode of geometry side by side and negative electrode or by on the opposite face that anode and negative electrode is printed on each separate layer and use shim to finish battery unit and realize with the production co-planar geometry by (on a surface of layer) between each opposite face.
Under the situation of lithium cells, anode is by forming lithium metal sputtering to the substrate 150 with intended shape.The formation of interconnection is identical with the by way of example with the conductive silver printing of suitable technology such as the silk-screen printing technique of aforementioned use.Negative electrode then use with construct core layer 130,140 with 145 to form similar the becoming layer method and be printed on the core layer 150 of electrolysis liquid trap.
In the zinc battery unit, even anode is still kept conductibility at interdischarge interval under the situation that zinc just is being consumed.The positive contact that forms negative pole end in housing exterior directly links to each other with the zinc China ink, rather than electrically contacts with the anode collector that separates.Under the situation of silk screen printing, for the ink impressionability is determined best aperture openings.Make the viscosity of size that factor that this decision need consider comprises the zinc particulate, ink and realize enough capacity necessary shear and required ink thickness under other flowing properties.The suitable source of other of zinc metal comprises zinc paper tinsel or zinc mesh, and they can be as the anode of battery pack.To can be by between the battery pack tectonic epochs, it being placed on this structure and realizing as picking up a part of placing line (pick-and-place line) such as the deposition of the material of zinc paper tinsel.
For the coplanar electrodes assembling, comprise separator 309 so that still can realize ion flow each electrode of electric insulation simultaneously." coplane " electrode is shared at each core layer apparent surface's main anode surface and the interface zone between the main cathode surface as used herein.(coplanar electrodes are different from electrode side by side, (anode adds current-collector in the main anode assembling in electrode side by side, if any) surface and main cathode are assembled (negative electrode adds current-collector, be positioned at if any) same plane substantially and be printed on directly or indirectly on the monolithic base material).Separator 309 between anode and cathode layer can be papery separator, colloid separator or printing separator.In carbon zinc execution mode, use the electrode assembling that has co-planar arrangement, the papery separator that is surrounded by brown paper can be used as separator.For the carbon zinc battery execution mode in according to the present invention, electrolyte preferably soaks into the solder(ing)acid of separator.
In printing process, can also form the contact of input trace from printed battery to the IC chip 180 that leads.(not shown) in one embodiment, the current-collector that is used for an electrode extends transversely into sealing area, and the second metallicity outer end extends into sealing area and contacts with current-collector in the sealing zone simultaneously.In this execution mode, being used for the mobile conductivity of electric current is provided by the contact of the physics between inside collector and the outer end.(not shown) in another embodiment, current-collector does not have physics to contact with outer end.On the contrary, conductivity is to be provided by the electroconductive binder or the epoxy resin that are positioned at sealing area and two structures of bridge joint to small part.Electrically contacting by the contact that extends to battery pack transverse sealing outside is provided of anode and negative electrode physically separated with electrolyte.It should be understood by one skilled in the art that the contact arrangement that also can realize other.
Anode and cathode external end or contact preferably use the conductive polymer ink based on silver to be printed on the flexible non-conductive polymer substrate.Cathode collector is printed on the external cathode contact, so that this current-collector and external contact overlap in the sealing area of battery unit encapsulation or container at least.In this way, the anode ink is printed on the external anode contact, so that this anode and external contact overlap in the sealing area of cell package or container at least.
Select the shape of cathode collector so that it can fully contact with the negative electrode ink, and can also preferably be formed on the zone that overlaps with negative contact in the sealing area.Oven dry current-collector ink, and in printed cathode ink and oven dry on current-collector subsequently.Be under the situation of co-planar arrangement at each electrode subsequently, separator 309 is placed between anode 303 and the negative electrode 305.
Can electrolyte be introduced battery pack structure by number of ways.In one embodiment, this method comprises that a kind of electrolyte with scheduled volume distributes to by the distribution system in the trap that forms of nuclear core construct.This trap is formed by the die-cut openings in basic unit 150 and each intermediate layer 145,130,120.The total height of trap depends on that each film thickness that is used for layer 145,130,120 is about 10 to 14 Mills.Resilient coating between layer 150/145,145/130 and 130/120 provides the battery pack sealing and prevents the electrolyte leakage of each interlayer.During heat lamination, the fusion that becomes of each battery pack layer and resilient coating is so that provide the sealing of high integrity for battery pack.If necessary, can use negative electrode and the moistening shim of anode that enhancing is provided.Alternatively, electrolyte enough colloid (for example, by using the suitable viscosity adjustment adhesive can not influence chemical property substantially) be printed on anode and the negative electrode by printing process to allow it such as silk screen or block printing.
Switch and other input blocks
Other electric components that can be integrated into electronics nuclear cored structure comprise switch contact shown in Figure 4 200 or provide or receive to the IC chip or to other devices of the input signal of entire circuit, such as transducer.
In many application, switch is the active electron device and opens the power supply of each parts necessary.Can use conventional diaphragm switch technology in the present invention.Can use the switch of various patterns, such as cheese, plate shaped or embossing shape switch.Under the situation of cheese switch, metal dome is placed on usually on the circuit of connecting compression.These domes can not be damaged or permanently damage by pressure each dome by heat lamination.
Alternatively, the electrical contact pad that is used for switch can be printed on layer 145 or be in other suitable layers in precalculated position and the degree of depth in the card.In case heat lamination is finished, can roll a cavity and place this dome and reseal this card with the flush switch dome.So, be non-typography though roll, can at first use critical piece electrogenesis in the next life daughter nucleus cored structure that is printed or is integrated into track.If require this application, this nuclear core just can have one subsequently and be rolled or the die-cut cavity that is used for this dome and still can benefiting from the typography at initial stage.Under the situation of dull and stereotyped switch, switch must be stacked under the situation of not destroying the pad of separating two one side of something of this circuit.Preferably the dome diameter is that 6 millimeters height are 0.018 inch.The dull and stereotyped switch that does not comprise the dome projection that is used to touch also uses the various layers except each layer shown in Figure 3 to make, and comprises flexible circuit layer, spacer layer and short circuit layer respectively.
Extraly or alternatively, each electronic unit can be included in layer of the present invention 145 place.Though each execution mode that illustrates uses display as an electronic unit, also can not deviate from scope of the present invention in conjunction with other devices such as magnetic stripe emulator, RF antenna or biology sensor.
Printed layers and interconnection
The surface of display unit 160 and each volumetric layer can be used for the necessary connecting circuit of bearing electric element.Because structure 100 can comprise multilayer, every layer the front and the back side all can be used for comprising the circuit of printable resistive, dielectric or miscellaneous part.Technology such as the through hole printing can be used for taking conducting channel to another side from the one side of layer.This method is known and by providing the via hole that runs through rete to realize, wherein this rete is electrically connected by providing the electric conducting material that runs through this via hole to realize.This circuit can adopt the form such as the conductive trace of other conductivity, resistive or dielectric substance known in printed silver or this area.Like this, except bring into as pre-assembling seldom several, all elements of stratification structure and parts can be printed on the track, also can be added into this track easily.For example, though IC 180 is current is by the explained hereafter beyond the printing, but also can carry out the part of the installation of this IC 180 as display unit 160 simultaneously in the track that is used to form these other layers of electronics nuclear cored structure, this IC can suitably be integrated into electronics nuclear cored structure thus.
Use typography just can at a high speed and produce each layer that has circuit feature spare that is used for multiple absolute construction in enormous quantities in the mode of sheet and/or volume at low cost.These have electric trace be printed on its one or two lip-deep pre-formation component layer subsequently just can be by individualized and in lamination process, be assembled between substrate and the top flat as mentioned above, and these layers have print structure and the via hole that matches on the position, to be provided between each layer and to lead to appropriately being electrically connected of display unit 160.
Known technology can be used for printing on printed layers or building various elements, comprises display pixel, conductive trace, resistor, switch, battery pack, capacitor and electroconductive binder.These elements or their parts can be printed on to be set up desired structure and is connected necessary use Fig. 2 A and Fig. 3 above-mentioned any layer top or bottom as a reference, and above-mentioned each layer comprises flexible circuit layer 140, first cover layer 120 and second cover layer 130.But these printed elements can also be printed on the extra layer not shown in Figure 3, but with realize by each additional layer more print surface is provided so that more complicated structure be connected.
For example, with reference to figure 3 and Fig. 4, can be formed for the diaphragm of switch 200 thus at first cover layer, 120 printed on top short circuit pads.As another example, can in appropriate location, second cover layer, 130 bottom, print along separate routes, be somebody's turn to do just contiguous flexible circuit layer 140 when assembling along separate routes like this, so that the circuit of expecting is skipped on the flexible circuit layer 140.Can also connect and each parts may be operably coupled to flexible circuit layer 140 to form at various other the parts of second cover layer, 130 bottoms printings, such as the electrode that is used for display 170, resistor, capacitor and antenna.In addition, the follow-up trace of printing just can form more complicated connection on same position to allow by printing transposition insulator on the each several part of expectation layer.
In another execution mode, electroconductive binder can together with non-conductive adhesive patterning in the lump be printed on the bottom of second cover layer 130 so that the electroconductive binder of patterned print can connect the expectation circuit on flexible circuit layer 140 and the layer 130.Can also realize a plurality of other printing structures, be included in the expectation layer and go up printed capacitor or resistor.The element of these printings can be installed at expectation layer upper surface alternatively.
With reference to figure 16A, existing smart card contact Cali with chip board 1610 block 1600 and and the intellignet card fetch (not shown) between form contact point.Microprocessor 1620 is attached to chip board 1610 by other the conventional attached die methods under wire-bonded, flip-chip or the chip board and traditionally by electrically and physically attached so that provide the place for data, processor and the programming that comprises on this card.In some embodiments, also provide colloid 1630 or other adhesives and holder 1640 to fix chip board 1610 and microprocessor 1620.The contact smart card is not connected to intelligent card chip the miscellaneous part in the card at present.Yet may wish this microprocessor is connected to interior other electronic units such as display or biology sensor of card.In these cases, the printed circuit on the core layer 145 can be used for providing the conducting path between intelligent card chip plate and the miscellaneous part such as IC 180.This will more at large describe following.
The battery pack interconnection
As previously mentioned, can connect and produce and connect two or more battery units to increase supply voltage.The geometry of battery unit can change, and with reference to figure 15A, in one embodiment, prints two battery pack and with side by side geometry interconnection.The anode 1550 of the anode 1540 of first battery pack and cathode collector 1560 and second battery pack and cathode collector 1570 are placed abreast and are printed.For these battery pack that are connected in series, conducting bridge 1510 is electrically connected to the anode 1540 of first battery pack to form negative pole end, and provide conducting bridge 1530 to form positive terminal, and the cathode collector 1560 of first battery pack is connected to the anode 1550 of second battery pack by conducting bridge 1520 from the cathode collector 1570 of second battery pack.
With reference to figure 15A and Figure 15 B, form the top of the conducting bridge 1510 of negative pole end as can be seen from anode 1540 guiding core layers 145.The conducting bridge 1530 that the forms positive terminal top (not shown in Figure 15 B) of core layer 145 of also leading.In order to realize running through between two batteries the interconnection of core layer 145, just on core layer 145, provide a through hole 1580.Conducting bridge 1520 bypasses are connected to the cathode collector 1560 of first battery pack under the core layer 145 by visible through hole 1580 among Figure 15 B the anode 1550 of second battery pack on the core layer 145.Similarly, provide and stretch out the cathode collector 1570 of second battery pack of conducting bridge 1530 under core layer 145 and bypass extends to the upper surface of core layer 145 to form positive terminal at these core layer 145 tops by through hole 1590.
Conducting bridge 1510,1520 and 1530 can use the conductive silver ink such as Spraylat XCM-01 to form.Referring to Figure 17, step 1720 and 1770 shows the printing of setting up these conducting bridges of a sequence part as the nuclear cored structure.Also show through hole 1580 and 1590 in the core layer 145 of Figure 17, they allow conductive ink to create the electrical connection that runs through core layer 145.
Abovely conducting bridge 1510,1520 and 1530 is described with reference to the interconnection battery pack that runs through core layer 145.Yet it will be recognized by those of ordinary skills these principles of electric conducting material guiding being crossed and running through each layer of this stepped construction and also can be applicable to other electric parts of the present invention and other layers.
Intelligent card in processing
Connecting under the electronic unit the comprised microprocessor situation of (such as, the microprocessor of driving display), the contact intelligent card chip can be removed from this structure.With reference to figure 16A, in this execution mode of the present invention, chip board 1610 is used to reader that the standard contact interface is provided at this, but does not have the back side that traditional smart card microprocessor 1620 is attached to this chip board.The microprocessor that is used to control display or miscellaneous part is served these two purposes that main memory is used for the software of element control and is usually located at the software that being used in the intelligent chip communicate by letter with external reader.
With reference to figure 16B, can use IC 180 to replace at present by the performed processing of integrated circuit in existing " smart card ".The physical structure of existing smart card is specified by iso standard 7810,7816/1 and 7816/2 usually.This structure is generally by two elements that embed in the card, and promptly printed circuit and integrated circuit (IC) chip 180 are formed.Referring to Figure 16 B, chip board 1610 is electrically connected with contact 1650, and this just allows the processing capacity of IC 180 or arrives plate 1610 from the signal of switch 1660 when chip board is positioned at standard reader.
Printed circuit shown in Figure 16 B is observed the iso standard 7816/3 that five tie points are provided for power supply and data.This chip board circuit is fixed in the groove that is provided on the card and is burned and is filled with in electric conducting material and the circuit chip by the sealing of contact projection by hermetic type.Printed circuit protective circuit chip avoids the influence of mechanical stress and static.Finish by " chip board " that comprise the contact that covers on the printed circuit with communicating by letter of chip.
Chip board is as the contact mat between card receiver equipment (CAD) or the card reader.Integrated circuit (IC) chip provides logic and function as the means of communication between card and the reader.Chip also contains suitable encipheror and other necessary security procedures.
According to the present invention, IC 180 driving displays 170.Yet also the demonstration processing capacity of IC 180 can be combined with the processing capacity of existing " smart card " integrated circuit.Two chips though in individual card, can coexist, if require smart card with such as other chip communications of display driver IC 180, then each data wire need connect by one group of trace.As mentioned above, the existing chip plate has 6 or 8 connections using for this chip, and they comprise power supply or other order wires.
For fear of the shortcoming of two independent IC, display driver IC 180 can be designed to comprise and existing intelligent card chip identical functions and memory.All programmings all can be included in the IC 180 on the intelligent card chip at present, remove second microprocessor thus.In order to realize this purpose, the chip board that meets smart card contact requirement is installed in the opening in flexible top flat 110, but is not had the IC that is associated.The processor that except IC 180, no longer needs other.Can on the surface of layer 145, second cover layer 130 and/or flexible circuit layer 140, print from the chip board to IC 180 and be connected, to allow to be used for the signal inflow and outflow IC 180 of standard intelligent card agreement with the suitable of battery pack 190.
Magnetic stripe emulator
As mentioned above, in nuclear cored structure of the present invention, can comprise multiple electric parts.A kind of suitable components can be such as at United States Patent (USP) the 4th, 701, the magnetic stripe emulator of equipment described in No. 601.Have magnetic stripe emulator card can with have in order to read and to use in the lump with the transaction terminal of the transducer that connects the magnetic stripe interface.Card can comprise the converter that generates and be coded in the corresponding variation magnetic field of information on the magnetic stripe usually.Under situation of the present invention, IC 180 extracts the transaction data that is stored in the memory and output signal is offered converter.Converter generates and the corresponding variation magnetic field of this transaction information, and wherein this transaction information is to be read by the transducer in the transaction terminal.So just generated the nuclear cored structure that comprises the magnetic stripe emulator that is used for the card application.
Biology sensor
Can be integrated into the electric parts of another kind of the present invention and be any in the various biology sensors.In one embodiment, biology sensor is to be designed for the micropressure sensor of supporting captured fingerprint image.The example of this a kind of appropriate sensor is that this transducer can embed the equipment based on microprocessor by the FidelicaImage Sensor model 3002 of the Fidelica Microsystems company production of California Milpitas.When with applicable host part when integrated, transducer allows the user to carry out multiple digital certificate safety function.Similarly, nuclear cored structure of the present invention can comprise this characteristic under the situation of card application need or expectation.
Resilient coating
Because the spatial character that different parts and film have nothing in common with each other and because each individual components and be used for the variation that the ISO requirement of gained card flatness produces in different examples, the assembling of structure 100 comprises resilient coating.These shapable layers are providing size (referring to Fig. 2 A) balanced and specific " H " that permission realizes as records to top flat 110 outsides from substrate 150 outsides in electronics nuclear cored structure among the various parts.
To be applied to such as the flowed padded coaming of adhesive in the structure 100 between the two-layer or multilayer.Variation as described below, that buffer layer conditions occurs in any production batch of every kind of parts and film.For example, the height of IC 180 may be skimble-scamble or be positioned at the nominal dimension of expectation, but this variation can be compensated by resilient coating.The height dimension H of expectation can realize by the buffering at the multilayer place; Because the size that size that all as described below being laminated in together of each layer of structure 100, flowable adhesive phase are each absorption of various parts and layer to be surpassed and filling do not reach.The roll that uses after buffering is used helps to set up desired size.Cavity in the grid of each die-cut layer absorbs the flowed adhesive from the over dimensioning element.These cavitys are designed to even up each element usually.Such as IC, battery pack and display unit.Because each cavity may not be formed the size of accurate each component variation of adaptation, so some can cause the areola of each component ambient to their size a little greatly.These padded coamings that can flow are filled these cavitys and unified structure are provided.
During heat lamination, be used to form the epoxy resin of examining each rete of cored structure and also flow.Can fill by the epoxy resin that in heat lamination technology, flows at the cavity that each component ambient forms.Because this epoxy resin is filled by the cavity that preformed cavity caused, so the possibility of result is owing to the VOLUME LOSS in the flow process causes the unacceptable blemish of card face, such as crack, crackle or depression.So just use the padded coaming that can flow to be filled in the cavity that produces in the nuclear core forming process in advance, removal can cause the volume of these defectives to lack thus.
Following two resilient coatings will be described, host buffer layer and time resilient coating.These resilient coatings can have the thickness of 1.0 to 3.0 Mills and the thickness of 0.25 to 1.0 Mill respectively.The preferred thickness of host buffer layer is 2.5 Mills and the preferred thickness of inferior resilient coating is 0.5 to 1.0 Mill.
The host buffer layer is at first described.With reference to figure 6, in the assembling process of structure 100, flexible top flat 110 is laminated to first cover layer 120 and first cover layer 120 is laminated to second cover layer 130, form top assembled layers 210 thus.Base assembled layers 220 by with all as shown in Figure 6 substrate 150, have display 170 and IC 180 display unit 160 and so on a plurality of elements and stack formation layer by layer.Use conventional lamination techniques that these element layers are stacked, and use roll to realize the expectation thickness of top assembled layers 210 and basic assembled layers 220.
Just as discussed, undesirable change in size can occur in the superimposed elements in these layers.Referring to Fig. 7, host buffer layer 230 is placed between top assembled layers 210 and the basic assembled layers 220 to even up basically and respectively changes and realize acceptable size.The host buffer layer can be used in the laminating adhesive that flows on the top assembled layers 210 as shown in Figure 8 and form.Host buffer layer 230 can by comprise silk screen, cut blocks for printing, the whole bag of tricks of impression or aniline printing is applied to top assembled layers 210.These typographies are used with top assembled layers 210 profiles and are finished as the plate of mirror image profile.Corresponding position is complementary on this plate and the top assembled layers 210, so that the abundant covering of adhesive to top assembled layers 210 grooves is provided.So, though Fig. 7 is in the resilient coating 230 that simple and clear consideration only shows unified thickness.But will have the pattern of material thickness and volume by this layer that said method is used, this pattern is selected to provide more material in order to the position that moves into cavity to a large amount of flowable materials of needs.The host buffer layer provides sufficient padded coaming to guarantee that formed size difference is compensated for and fills with the cavity during the nuclear core forms.
Referring to Fig. 9, top assembled layers 210 and basic assembled layers 220 are merged, and the size that surpasses in host buffer layer 230 each parts of absorption of patterning and the size of lack of fill, fill up height change thus to finish by the determined Desired Height size of roll.Allow any unnecessary padded coaming to ooze out and be trimmed to form the shape of expectation subsequently from the edge of emulsion sheet.
Use resilient coating that the mechanical strength of expectation can also be provided for the electronics nuclear cored structure that obtains at last.Assemble various elements and cavity by providing substantially for the structure of solid, the nuclear cored structure that obtains at last will present very gratifying hardness and mechanical integrity.In addition, use resilient coating each layer to be locked together the electric integrality that has increased the interconnection electronic circuit.Suitable cushioning layer material should have suitable viscosity or other physical characteristics are applied to typography to allow it, and it should flow and curable, thereby helps each nuclear cored structure layer is combined.Yet padded coaming needs not to be permanent adhesives.Cushioning layer material can also mix mutually with PVC or other layers and any extra printing material in the heat lamination process, so that the resin of each rete of this padded coaming and molten state and electric parts is compatible mutually.Multiple material family all is suitable for as padded coaming, such as acrylates, polyurethane rubber, plastisol, polyester or have suitable viscosity to realize other similar materials of printing and cured strength.
Except the host buffer layer 230 that adheres to flexible circuit layer 140, can also be shown in as Figure 10 and 11 and flow between other each layers and adhere to resilient coating 240 a plurality of times.Realize the height dimension expected by the compensation buffering of the multilayer place in structure 100 like this.Inferior resilient coating also is used for during manufacture each layer being bonded together.At last, inferior resilient coating and central roll make to be placed on base top or bottom by the renewable place of production to fixed structure and are separated by on the position of known distance.This expects to use milling or other technology will be very important under with the situation that connects any element in the embedded nuclear cored structure the terminal use.
Except can balanced each parts and the height dimension of layer, host buffer layer 230 and time resilient coating 240 can also be corrected other dimensional problem.For example, want stacked layer punched with the situation that is applicable to IC 180 under, may need " crossing cutting " to allow this light in structure to change places and hold IC." crossing cutting " of appearing in the nuclear of the electronics one by one cored structure changes different with the variation of IC size.Though can form the IC shape with acceptable size, their placement meetings on structure 100 change to some extent, and this will cause the change in location of needs compensation.Therefore, be mounted to this structure and after having used die-cut layer around it, may around it, form cavity at a chip.In the case, resilient coating not only will be filled up the height change of IC as shown in figure 11, also will fill IC 180 cavity volume 290 on every side.
The placement of embodiment 1-separating component and the circuit that becomes multilayer
Consistent with above-mentioned teaching, now shown in the structure that has two synthetic layers, these two layers are shown in Figure 6 to be basic unit 220 and cover layer 210 in the present invention, and they are laminated in subsequently together to form electronics nuclear cored structure.
Electronics nuclear core is constructed by place necessary parts with the suitable configurations that is used for part placement on substrate 150.Substrate can be to pass through heat lamination technology and stacked PVC or other films of each exterior layer.The preferred range of substrate thickness is between 0.001 to 0.005 inch, and preferred thickness is 0.002 inch.Use contact adhesive with each parts fix in position.
The parts that are placed on the substrate 150 comprise diaphragm switch dome, battery pack and display unit.Initial parts are placed and have been determined to alleviate the interval in district (relief area) and the various height that need even up.Expectation but do not require pre-stacked die-cut layer 145 is so that be complementary with the substrate thickness of display unit and battery pack joint.The surface of substrate can comprise and will place the switch base circuit of dome thereon.
Preferential laminating method is to use by UV irradiation, EB irradiation or the permanent laminating adhesive that is heating and curing.Basic unit is stacked can pressurize by the point (nippoint) of nipping that this layer height is set and reduces the potential height change of this layer.
