Abstract
Description
Technical Field
[0001] The present invention relates to a method of forming a prelaminated inlay body for a smart card and a method of forming a smart card. Furthermore, the present invention relates to a prelaminated inlay body for a smart card and a smart card. Background Art
[0002] In general, a smart card is a physical electronic authorization device used to control access to resources. Typically, a smart card is provided as a credit card-sized plastic card formed by a card body in which one or more electrical and electronic components, such as a chip, an antenna, contact elements, etc., are integrated, wherein the card body after integration is referred to as a smart card. Many smart cards include a pattern of metal contacts for electrical connection with an integrated chip and / or are configured to allow contactless or wireless communication with the smart card. In the case of a contactless smart card, one or more antenna components are integrated into the body of the smart card to enable contactless or wireless interaction with the chip integrated into the smart card.
[0003] In order to improve the functionality of smart cards, efforts are increasingly being made to include more and more features into a single smart card. For example, one or more security feature modules are integrated into the card body of the smart card to improve the security of the smart card and / or one or more memory modules are integrated into the smart card to store sensitive personal data. Another application of smart cards aims to use the smart card as a key, which includes a key device for accessing personal belongings such as a house, a car, a room in a hotel, etc. There are many possible functional modules that need to be integrated into the smart card, such as a fingerprint sensor for implementing a biometric card and / or a dynamic CVV to implement a dynamic CVV function, one or more chip modules, a display, a battery module, an antenna module, etc.
[0004] As more and more features are added to smart cards, more and more interconnects will be integrated into the card body of the smart card. For example, when implementing a contactless smart card with biometric security features, up to twenty interconnects may be required between the printed circuit board and the feature module implementing the contactless and biometric features.
[0005] The dimensions of current smart cards are generally similar to those of credit cards. The typical size of a smart card is given by ID-1 of the ISO / IEC 7810 standard, which defines the card as nominally 85.60 mm × 53.98 mm (3.37 in × 2.13 in). Another common size is ID-000, which is nominally 25 mm × 15 mm (0.98 in × 0.59 in), which is commonly used in SIM cards. In each case, a thickness of approximately 0.76 mm (0.030 in) is given. Therefore, the size of smart cards is considered standardized and therefore will not change even if more and more features are to be integrated into the smart card. Therefore, when the number of contacts and interconnects is increased, the size of the interconnects must be adjusted proportionally to enable more and more contacts and interconnects to be integrated into the card body. It becomes a problem to provide high-quality electrical interconnects between the integrated features and the integrated circuit in the card body and to ensure reliable interconnections during the long-term use of the smart card.
[0006] When the size of contacts and interconnects, such as copper pads, is adjusted proportionally in the card body of a smart card, several problems may occur. For example, a large number of copper pads may increase the complexity of integrating the copper pads into the card body. In addition, the placement of copper pads in conventional pick-and-place processes has been shown to be less accurate when considering dimensional changes. On the one hand, this affects the tolerances of the processes used during various stages in the smart card manufacturing process, such as lamination, card cutting, card milling, and embedding one or more modules into the body. On the other hand, misplaced copper pads may impair the reliable function of any module to be connected to the copper pads. For example, the thermocompression bonding (TCB) used to equip the card body with an antenna module by bonding the copper wiring of the antenna to the copper pads in the card body may result in the milling of the copper wires (as is usually required by the TCB process), because it is difficult to control with the copper pads adjusted proportionally. These copper pads are currently considered to be reliable, easy and cost-effective interconnects in the application of smart cards.
[0007] As a clear embodiment of a smart card, a dual interface card is known in the prior art. A dual interface card is a smart card comprising two interfaces for sending and receiving information, one interface being an electrical contact for a galvanic connection and the other interface being configured for contactless sending or receiving of data, usually by means of an RF antenna. Several specific connection terminal designs are known in dual interface cards, which are designed taking into account different technical and application-related constraints. As described above, when more features are integrated into a dual interface card, the number of interconnections increases, which requires a change in the known specific connection terminal design, or even a completely new design of the connection terminal design.
[0008] In particular, when more functions are integrated into the dual interface card, the number of pads to be positioned in the same available space provided by the body of the card increases greatly. For example, a typical dual interface card without other functions has two connections, and integrating one or more other electronic modules into the card increases the number of connections to up to eight or ten or even more connections. The limited space of the card body makes it necessary to adjust the pad size proportionally, thus making it more difficult to assemble the pad into the pre-laminated inlay body or the card body. The problem involved is the positional accuracy of the pad, which becomes even more important when the pad size is proportionally adjusted to a smaller size. However, the smaller pad size also results in a smaller tolerance relative to the position of the pad to avoid possible mismatches between the terminals in the card body and the contacts of the electronic modules that are later integrated into the card. This means that during the manufacture of the pre-laminated inlay body, the conductive pads need to be properly kept in place. In the current process, the adhesive tape of the pre-laminated inlay body temporarily fixes the two large pads of each dual interface card. This technique is not efficient for applications configured with multiple smaller conductive pads.
[0009] Therefore, it is generally important to efficiently design an interconnection layout that is capable of accommodating the various electronic modules associated with the functions to be integrated into the dual-interface card, and to configure the interconnections and connection terminals in the confined space of the body of the smart card so as to provide high-quality electrical contacts and interconnections between the integrated features and the integrated circuit in the card body and ensure reliable interconnections during long-term use of the smart card.
[0010] An object of the present disclosure is to provide a pre-laminated inlay body with multiple conductive pads configured in an efficient and cost-effective manner.Herein, the size and design of the copper pads and routing will be designed to efficiently use the space provided by the body of the smart card. Summary of the invention
[0011] The above problems are solved and the above objects are achieved in various aspects of the present disclosure. Some aspects relate to a method of forming a pre-laminated inlay body for a smart card according to independent claim 1, a method of forming a smart card as defined in claim 15, a pre-laminated inlay body for a smart card according to independent claim 16 and a smart card according to claim 28. More advantageous embodiments are defined in dependent claims 2 to 14 and 17 to 27.
[0012] With regard to the expression "pre-laminated inlay body" as used herein, it is understood that it is a pre-laminated body having multiple layers of insulating material, such as PVC, pre-laminated together. The pre-laminated body is an intermediate product obtained during the manufacture of a smart card. For example, an illustrative pre-laminated inlay body can be obtained by fusing together different layers of thermoplastic material into a single homogeneous sheet body, thereby embedding a substrate having at least one contact and / or interconnection in the pre-laminated inlay body.
[0013] Regarding the expression "body of the smart card", the expression mentioned in this specification refers to the physical body of the smart card. For example, depending on the stage during the manufacture of the smart card, the body of the smart card at a given stage during the manufacture is the physical body of the smart card at a given stage during the manufacture, which only includes the physical elements that physically constitute the smart card at the given stage during the manufacture. In another embodiment, the body of the finally completed smart card can be understood to include a pre-laminated inlay body and at least one feature module integrated therein.
[0014] With regard to the expression "card body", the expression refers to a pre-laminated inlay body having a top layer and / or a bottom layer and one or more optional compensation layers mounted thereto. In particular, the card body is the body of the smart card in the manufacture of the smart card at a stage after the preparation of the pre-laminated inlay body and before the integration of at least one electronic module into the body of the smart card. In other words, the card body is the body of the smart card at a manufacturing stage, at which the geometrical dimensions of the body comply with the geometrical dimensions defined according to the ISO standard for smart cards.
[0015] In a first aspect, a method for forming a pre-laminated inlay body of a smart card is provided. According to an illustrative embodiment of the present invention, the method includes: preparing at least one contact terminal patch, which is formed by a patch base layer and a plurality of conductive pads disposed on a surface of the patch base layer, wherein the plurality of conductive pads are configured on the patch base layer according to a predetermined interconnection design; preparing a pre-laminated inlay sheet having a plurality of openings formed therein, each opening being formed so as to accommodate a specific conductive pad among the conductive pads; and mounting the at least one contact terminal patch to the pre-laminated inlay sheet.
[0016] When preparing at least one contact terminal patch, a predetermined interconnection design of the conductive gasket can be easily provided in an automated manufacturing process. In this context, the size of the conductive gasket can be proportionally adjusted to be smaller on the contact terminal patch with high precision, and the predetermined interconnection design of the conductive gasket can be provided independently of any assembly or lamination process performed during the manufacture of the pre-laminated inlay body. In addition, the patch base layer can be selected based on the material used to manufacture the pre-laminated inlay body, such as PVC, PC or similar thermoplastic materials used in the field of manufacturing pre-laminated inlay bodies, so that at least one contact terminal patch can be reliably integrated into the manufacture of the pre-laminated inlay body. Therefore, a pre-laminated inlay body with a predetermined interconnection design of a conductive gasket integrated therein can be provided for automated manufacturing of the pre-laminated inlay body in a cost-effective manner.
[0017] In a first embodiment of the first aspect, the method may further include: preparing a covering layer having at least one recess formed therein, the at least one recess being formed to accommodate at least one contact terminal patch.

The at least one recess in the pre-laminated inlay sheet is at least one location where the at least one contact terminal patch is located in the pre-laminated inlay body. The recess in the covering layer positions the contact terminal patch with reference to the pre-laminated inlay sheet. In the case where more contact terminal patches are prepared to be accommodated in the pre-laminated inlay sheet, a recess is formed for each of the contact terminal patches so that each contact terminal patch is accommodated in a specific one of the recesses, and the conductive pad of each contact terminal patch is also accommodated in a corresponding opening in the opening in the pre-laminated inlay sheet. In this way, the recess in the cover layer is aligned with the corresponding opening in the pre-laminated inlay sheet. The conductive pad and the contact terminal patch can be embedded in the pre-laminated inlay sheet and in the cover layer so that the position of the conductive pad and the contact terminal patch remains fixed accordingly during the subsequent processing during the manufacture of the pre-laminated inlay body and the smart card.
[0018] According to some illustrative examples of the first embodiment, the thickness of the cover layer is substantially equal to the thickness of the patch base layer of at least one contact terminal patch.

This embodiment of the reel-to-reel process enables the preparation of at least one contact terminal patch in an easy and automated manner, while collecting the cutting strip of conductive pad material for possible recycling of the material. Therefore, the amount of waste material can be reduced.

[0070] refer to Figure 8 The conductive pad can be arranged on the patch base layer of the contact terminal patch so that the conductive pad is not constrained to be completely located within the surface of the patch base layer in a top view. Figure 8 As shown in FIG. 5 , at least one of the configurations of the conductive pads may be configured on the patch base layer such that the conductive pad partially extends beyond the surface of the patch base layer. Thus, the conductive pad protrudes away from the patch base layer in a direction that is not parallel to the normal direction of the upper surface of the patch base layer on which the conductive pad is configured.
[0071] refer to Figure 3 , schematically showing an exploded cross-sectional view of a pre-laminated inlay body 100 according to some illustrative embodiments of the present disclosure. The pre-laminated inlay body 100 includes a plurality of contact terminal patches 10, a pre-laminated inlay sheet 20 and at least one insulating layer, such as a first laminate layer 50 and a second laminate layer 40b, such as a bottom shielding sheet. The plurality of contact terminal patches 10 include contact terminal patches 1a and contact terminal patches 1b. This does not constitute any limitation to the present disclosure, and there may be any number of terminal patches, such as at least one contact terminal patch.
[0072] According to some illustrative embodiments of the present disclosure, the size of the pre-laminated inlay sheet 20 is larger than each of the contact terminal patches 1a and 1b. Figure 3 The illustrated pre-laminated inlay sheet 20 may be one layer of PVC or may be comprised of a plurality of sub-layers (not shown) which collectively represent the pre-laminated inlay sheet 20 .
[0073] The contact terminal patch 1a is formed by a patch base layer 3a and a plurality of conductive pads 5 formed on the surface of the patch base layer 3a. Hereinafter, the surface of the patch base layer 3a on which the conductive patch 5a is disposed is referred to as the upper surface or the front surface, and the opposite surface of the patch base layer 3a is referred to as the lower surface or the bottom surface. Similarly, the contact terminal patch 1b includes a patch base layer 3b and a plurality of conductive pads 5b disposed on the front surface of the patch base layer 3b. Figure 1a , Figure 1b and Figure 8 The contact terminal patches described are provided for each of the contact terminal patches 1a and 1b.
[0074] With respect to the contact terminal patches 1a and 1b, the upper surface or front surface of the pre-laminated inlay body 20 is determined as the surface of the pre-laminated inlay body 20 close to the conductive pads 5a, 5b of the contact terminal patches 1a and 1b. Therefore, the surface opposite to the upper surface or front surface of the pre-laminated inlay body 20 is determined as the lower surface or bottom surface of the pre-laminated inlay body 20. Figure 3 , openings 22a and 22b are formed in the pre-laminated inlay sheet 20, each of the openings 22a, 22b extending at least partially through the pre-laminated inlay sheet 20 along the thickness direction of the pre-laminated inlay sheet 20. Figure 3 The openings 22a and 22b are schematically shown as through holes extending completely through the pre-laminated inlay sheet 20 along the thickness direction of the pre-laminated inlay sheet 20, which does not constitute any limitation to the present disclosure, and the openings 22a and 22b may extend only partially into the pre-laminated inlay sheet 20 along the thickness direction of the pre-laminated inlay sheet 20. The lateral size of the openings 22a and 22b may be such that the contact terminal patches 1a and 1b are accommodated into the openings 22a and 22b with respect to the length and width dimensions perpendicular to the thickness direction of the pre-laminated inlay sheet 20. In particular, the inner diameters of the openings 22a and 22b may be selected such that the contact terminal patches 1a and 1b fit snugly into the openings 22a and 22b with reference to the length and width dimensions of the contact terminal patches 1a and 1b.
[0075] According to some illustrative embodiments of the present disclosure, the thickness of the pre-laminated inlay sheet 20 may correspond to the total height of each of the contact terminal patches 1a and 1b, so that when the contact terminal patches 1a and 1b are inserted into the openings 22a and 22b, the upper surfaces of the conductive pads 5a and 5b are substantially flush with the upper surface of the pre-laminated inlay sheet 20. In the case where the openings 22a and 22b are through holes, such as Figure 3 As shown, when the thickness of the pre-laminated inlay sheet 20 is appropriately matched to the total height of the contact terminal patches 1a, 1b, the lower surface of the contact terminal patches 1a and 1b can be substantially flush with the lower surface of the pre-laminated inlay sheet 20. Therefore, the contact terminal patches 1a and 1b can be accommodated in the openings 22a and 22b without the raised portions of the contact terminal patches 1a and 1b extending beyond the surface of the pre-laminated inlay sheet 20. In this way, reliable lamination of the layers in the pre-laminated inlay body being manufactured is ensured.
[0076] On the front surface of the pre-laminated inlay sheet 20, after the contact terminal patches 1a and 1b are accommodated in the openings, a top covering shielding sheet 40t may be provided. Thus, the pre-laminated inlay body 100 may be formed by the pre-laminated inlay sheet 20 having the accommodated contact terminal patches 1a and 1b together with the layers 50, 40b and 40t on the upper and lower surfaces of the pre-laminated inlay sheet 20, as shown in FIG.

Band B2 and band B1 can be combined so as to extend on top of each other in a stacked configuration and converge toward each other without physical contact before workstation C. At workstation C, band B2 and band B1 can be processed in the following manner.

After the electronic modules are integrated into the card body CB, the card body CB is referred to as the "body CB of the smart card SC".
[0125] like Fig. 9As shown, electronic modules M1 to M4 can be interconnected through wiring pattern WP. For example, electronic modules M1 and M2 can be directly connected through wiring pattern WP. Additionally or alternatively, the electronic module can be indirectly connected through wiring pattern WP and at least one contact terminal patch, and / or the electronic module can be in direct contact with one or more contact terminal patches. For example, contact terminal patches CP1 to CP3 can provide an interconnection pattern for connecting wiring patterns and / or electronic modules. This means that electronic modules M1 and M2 can be coupled via wiring pattern WP and contact terminal patch CP1, for example, electronic modules M3 and M4 can be connected via wiring pattern WP and contact terminal patch CP3. The wiring pattern can be connected to contact terminal patches CP1 to CP3 to implement antenna coil patterns. In some illustrative embodiments, one or more electronic modules can be connected to one or more contact terminal patches via direct electrical contact between one or more back contacts (not shown) of the electronic module and one or more specific conductive pads (not shown) of the one or more contact terminal patches. In this document, a cavity (not shown) formed in a card body for accommodating an electronic module may expose one or more conductive pads (not shown) in the card body, and when the electronic module is accommodated in the cavity, the one or more conductive pads exposed in the cavity may form electrical contact with one or more back side contacts (not shown) of the electronic module.
[0126] After fully reading this disclosure, those skilled in the art will understand that the contact terminal patches can be configured together with the wiring patterns and / or electronic modules according to a predetermined interconnection pattern, so that the limited space of the card body CB in the smart card SC can be effectively used to optimize the number of modules and wiring patterns integrated into the smart card SC. The positions of the contact terminal patches CP1 to CP3 can be set with greater precision. Furthermore, the conductive pads (in Fig. 9 The conductive pads (not shown) can be arranged on each contact terminal patch CP1 to CP3 with high precision, regardless of the processing to which the smart card SC is subjected. Therefore, the conductive pads (in the embodiment of FIG. 1 ) can be adjusted proportionally without compromising the positioning accuracy of the contact terminal patches CP1 to CP3. Fig. 9 The size and quantity of (not shown) are not shown.
[0127] The interconnection between the conductive pads of the contact terminal patch, the conductive pads of the electronic module (not shown) and the wiring pattern is not limited and can be performed by using any known interconnection technology, such as anisotropic or isotropic adhesive bonding, soldering, micro welding, etc.

[0129] like Fig.10 As shown, each of the contact terminal patches 220a, 220b may have a plurality of conductive pads 222a and 222b, respectively. At least one of the plurality of conductive pads 222a of the contact terminal patch 220a and / or at least one of the plurality of conductive pads 222b of the contact terminal patch 220b may be connected to the wiring pattern 210 and / or to an electronic module 230 integrated into the card body 200. According to some illustrative embodiments, the electronic module 230 may be one of an LED, a chip, and the like. For example, the electronic module 230 may be directly connected to at least one of the contact terminal patches 220a and 220b, or may be indirectly connected to at least one of the contact terminal patches 220a and 220b. In this regard, Fig.10 An illustrative but non-limiting embodiment is shown in which the electronic module 230 is connected to one conductive pad of the contact terminal patch 220a and one conductive pad of the contact terminal patch 220b.
[0130] Despite Fig.10 The illustrated contact terminal patches 220a and 220b are similar to the contact terminal patches 1 shown in FIG. 1 of the present disclosure, but this does not constitute any limitation to the present disclosure, and any configuration of the plurality of conductive pads 222a, 222b on each of the contact terminal patches 220a and 220b other than the configuration explicitly depicted may be provided instead. By way of example but not limitation, at least one of the contact terminal patches 220a and 220b may be formed by the present disclosure.

[0132] According to some illustrative and non-limiting embodiments herein, some conductive pads of at least one of the contact terminal patches 220a and 220b may not have any other connection to the card body and may be present to provide better mechanical stability. Fig.10 As shown, two conductive pads can directly connect the contact terminal patches 220a and 220b. Additionally or alternatively, there can be an indirect connection between the contact terminal patches 220a, 220b and the electronic module 230 that has been integrated into the pre-pressed layer inlay layer, and the card body 200 is formed by the pre-pressed layer inlay layer. In addition, the contact terminal patch 220a can have two conductive pads 222a that are directly connected to each other. In the case where there are restrictions on the connection of components (not shown) directly performed on these modules (not shown), this can help to create an interconnection between two components (not shown) on a module that is later integrated into the card body 200.
[0133] refer to Fig.10 The card body 200 shown in FIG. 1 can be used to manufacture a smart card by integrating an electronic module (not shown) into the card body 200 at the location of each of the contact terminal patches 220a and 220b. Fig.10 The card body 200 is manufactured into a smart card (not shown) having a total of two electronic modules (not shown), wherein these electronic modules (not shown) will make contact with some conductive pads provided by the contact terminal patches 220a and 220b, which are in Fig.10 In the illustration, it is not connected.
[0134] Reference Fig.11 , schematically shows in top view an illustrative embodiment for manufacturing a tape 300 having a plurality of conductive pad assemblies 330 formed thereon. In the text, a plurality of contact terminal patches (not shown) can be produced from the tape 300 by appropriately cutting the tape 300 having the assemblies 330 into tape segments. Fig.11As shown, a strip of base patch material 310 may be provided. The strip of base patch material 310 may be provided with a layer of adhesive material (not shown) located on the upper surface of the strip of patch base material 310. A plurality of conductive pads 320 may be configured on the strip of patch base material 310. For example, a plurality of conductive pads 310 may be prefabricated in a desired shape, for example by stamping out conductive pads from a metal strip (not shown) or a sheet of metal (not shown) in a desired shape. After providing a plurality of conductive pads 310, each conductive pad may be mounted to the strip of patch base material 310 in a desired configuration using a pick and place technique. Each of the conductive pads placed may be fixed to the strip of patch base material 310 in a desired configuration by curing the adhesive at the placed conductive pads, for example by thermal curing or by UV curing or chemically curing the adhesive at each placed conductive pad. The tape 300 having the plurality of conductive pad assemblies 330 may be an intermediate tape wound into a reel, which may later be provided to a subsequent reel-to-reel process (e.g., as Figure 6a or 7a) and the gasket can be transferred from the belt 300 to the corresponding Figure 6a In the band B1 or Figure 7a In this embodiment, the wound tape 300 may be Figure 6a Scroll R2 or Figure 7a Scroll R2' in.
[0135] Reference Fig.12 , an optional additional process step is shown. This additional process step can be applied when a plurality of patches are produced in a reel-to-reel process, for example in the context of FIGS. 6 and 7 , wherein the conductive pads are cut or punched out of a strip of conductive pad material (see strip B2 in FIG. 6 and strip B2 in FIG. 7 ) by means of a rotary cutting or punching tool. When a rotary cutting or punching tool is used, the conductive pads are produced due to the cutting or punching geometry of the rotary cutting or punching tool as in Fig.12 The conductive pad 420a is a curved conductive pad shown in the figure. It should be noted that when the cutting or punching process is performed without using a rotating tool, such a curved conductive pad 420a is not obtained. Fig.12 In the process shown, a single conductive pad 420a is mounted on a reel 440 (see also Figure 6a-6c The tape B1 is provided by reel R1 and by Figure 7a-7c After being mounted on a base patch layer provided by a tape B1 ′ provided by a reel R1 ′ in FIG. 1 , it may happen that the conductive pad is mounted in a deformed shape due to the spin cutting process and therefore does not have a flat shape, which may impair the mechanical attachment of the conductive pad to the base patch layer.
[0136] like Fig.12As shown, a calendaring process 450 is applied to deform the pads into a generally flat shape 420b when mounted on the patch base by pressing each patch between two reels, so that the deformation of the conductive pad 420a is corrected.
[0137] Reference Fig.13a and Fig.13b , schematically shows another embodiment of a 3D-shaped conductive pad structure 520. The 3D-shaped conductive pad structure 520 may have a substantially Z-shaped shape, such as two planar portions connected by a stepped portion. When the 3D-shaped conductive pad structure 520 is integrated into the patch base layer 510, the upper planar portion is located on the top of the patch base layer 510, and the lower planar portion is accommodated in the concave portion of the patch base layer 510, as shown in FIG. Fig.13a For example, in an illustrative process flow, a strip of patch substrate material (not shown) may be provided, such as strip B1 in FIG. 6 or strip B1' in FIG. 7. The strip of patch substrate material (not shown) may be subjected to a process for forming at least one recess in the strip of patch substrate material (not shown), such as may correspond to Figure 6a In this embodiment, as shown in FIG. Figure 6a The shown coupling hole BH may be a corresponding recess. Alternatively, the size of the recess may be larger than the coupling hole, for example, a lengthy recess.
[0138] refer to Fig.13a, a strip of conductive gasket material (not shown) may be disposed over a strip of patch base material (not shown), and conductive gasket strips (not shown) may be cut or punched out by means of a rotary cutting or punching tool (not shown) and the conductive gasket strips (not shown) may be deformed under pressure of a pressing tool 540, so that each conductive gasket strip is deformed under pressure into a 3D-shaped conductive gasket structure 520, wherein the lower planar portion of the conductive gasket structure 520 is deformed into a recess in the patch base layer 510 using the pressing tool 540, and the upper planar portion is located on the upper surface of the patch base layer 510 and is located on top of the patch base layer 510. This process may be used in a reel-to-reel patch manufacturing process, in which a 3D-shaped conductive gasket structure 520 is formed by deforming a portion of the conductive gasket strip into a recess of the patch base layer 510. Advantageously, the upper planar portion of each conductive pad 520 on the patch base layer 510 can be positioned at different height levels depending on the thickness of the pre-laminated inlay / card body (not shown). When the lower planar portion of the conductive pad 520 is positioned in the recess of the patch base layer 510, easier access to the conductive pad 520 leading to the wiring inside the card can be provided. When the electronic module (not shown) is integrated into the card body, since the lower planar portion of the 3D-formed conductive pad structure 520 is accommodated at a lower level compared to the upper planar portion of the conductive pad structure 520 (which may be exposed to contact with the backside contacts (not shown) of the electronic module (not shown)), the contact with the internal wiring can be protected from damage when a milling process is performed.
[0139] refer to Fig.13a For mechanical stability reasons, a liner 530 may be provided below the patch base layer 510, at least temporarily until a contact terminal patch (not shown) is cut out from the patch base layer 510 after the conductive pads 520 are mounted to the patch base layer 510. For example, the liner 530 may be removed before laminating a contact terminal patch (not shown) having a plurality of conductive pads 520 into a pre-laminated inlay body.
[0140] Reference Fig.14 , some illustrative embodiments are shown, in which a 3D-shaped conductive pad 620 having a generally L-shaped or C-shaped (or U-shaped) shape is employed. Fig.14 In step S1 of the present invention, a conductive gasket 620 is provided. The conductive gasket 620 has a planar base portion 622 and at least one leg portion 624 extending perpendicularly to the base portion 622 and away from the base portion 622. When the conductive gasket 620 is mounted to the patch base layer 610, the base portion 622 is configured to lie flat on the patch base layer 610, and the leg portion 624 is oriented approximately perpendicularly to the base portion 622.
[0141] like Fig.14As shown in step S2, the legs 624 (one leg 624 (not shown) of the substantially L-shaped conductive pad and two legs 624 of the substantially C-shaped conductive pad) are inserted into the holes 612 (e.g., corresponding to the holes 612) formed in the patch base layer 610. Figures 6a to 6c For example, the pattern of the coupling holes 612 may be formed according to the conductive gasket 620 so that the conductive gasket 620 may be mounted to the patch base layer 610 by inserting the legs 624 into the holes 612 of the patch base layer 610.
[0142] Subsequently, in step S3, the leg portion 624 may be deformed to lie flat on the side of the lower surface of the patch base layer 610, while the base portion 622 of the conductive pad 620 lies flat along the upper surface of the patch base layer 610. Therefore, the conductive pad 620 is mechanically fixed to the patch base layer 610, and the conductive pad 620 may be contacted from two opposite sides of the patch base layer 610. For example, contact with the conductive pad 620 may be achieved by contacting the base portion 622 at the upper surface of the patch base layer, while other contact may be achieved by contacting the leg portion 624 of the conductive pad 620 at the lower side of the patch base layer 610.
[0143] As Fig.14 The advantage of the embodiment is that the crimping of the conductive gasket 620 to the patch base layer 610 also achieves the fixation of the conductive gasket 620 to the patch base layer 610 without the need to use additional glue for fixation.
[0144] According to some illustrative embodiments, the process may include steps S1 to S3. The process may be integrated into any of the reel-to-reel processes described above. For example, the corresponding process may include:
[0145] During cutting or punching of the conductive pad from the strip of contact material, the conductive pad may be deformed into a 3D shape having a base portion and at least one leg extending substantially vertically away from the base portion.
[0146] - The 3D formed gasket may then be placed onto the patch base layer by positioning at least one leg into a hole in the patch base layer.
[0147] - Subsequently, in a crimping process, at least one leg may be folded to lie flat beside the patch substrate layer, thereby securing the conductive pad to the patch substrate layer.
