Abstract
Description
Technical Field
[0001] This application relates to components used in smart card manufacturing, and more particularly to carrier tapes for smart card modules, smart card modules, and smart cards. Background Technology
[0002] Smart cards (such as SIM cards, bank cards, etc.) consist of a smart card module. A smart card module (such as a contact smart card module) consists of a carrier tape and a chip. The carrier tape is in the form of a roll or strip, and the chip is attached to the carrier tape and connected to the carrier tape via wires.
[0003] When a smart card malfunctions, it's necessary to confirm relevant information such as product attributes (e.g., processing information) to identify and troubleshoot the problem. One approach is to read the chip information and investigate the processing history for confirmation. However, if the chip information cannot be read or the processing history is difficult to access, it becomes challenging to quickly confirm product attributes and other relevant information. Utility Model Content
[0004] The purpose of this application is to disclose a carrier tape for a smart card module, a smart card module, and a smart card, so as to quickly confirm relevant information such as product attributes.
[0005] In a first aspect, this application discloses a carrier tape for a smart card module. The carrier tape includes a visually visible identifier, which comprises multiple graphics.
[0006] In some embodiments, the smart card module carrier tape includes a base fabric and a conductive layer formed on the base fabric, the conductive layer having contacts for connecting the chip, and the identifier.
[0007] In some implementations, the plurality of graphics constitute Morse code.
[0008] In some implementations, all the graphics of the identifier are formed at the same contact point.
[0009] In some implementations, the mark is formed on the contact point with the largest area.
[0010] In some implementations, the contact is provided with a connection area for connection to the chip, and the identifier is separate from the connection area.
[0011] In some implementations, the marking is formed on the edge of the contact point.
[0012] In some embodiments, at least a portion of the plurality of patterns are notches.
[0013] In some embodiments, the notch includes at least one of the following features: a) the notches are not the same shape; b) the distances between the notches are not equal; c) the notch includes at least one of a first notch and a second notch, wherein the first notch is an arc-shaped notch; the second notch includes a first sidewall and a second sidewall; the first sidewall extends along a stepping direction perpendicular to the carrier tape of the smart card module, the second sidewall extends along the stepping direction, and is connected to the first sidewall by a chamfer.
[0014] In some embodiments, the carrier tape for the smart card module includes a base fabric, and all the markings are located on the side of the contact along the stepping direction of the carrier tape for the smart card module, or on the side of the contact in the opposite direction of the stepping direction.
[0015] Secondly, this application discloses a smart card module. The smart card module includes any of the aforementioned smart card module carrier tapes.
[0016] Thirdly, this application discloses a smart card. The smart card includes any of the aforementioned smart card modules.
[0017] For the carrier tape used in the smart card module, the smart card module, or the smart card itself, product identification and traceability are achieved based on the information corresponding to the identifier, thus serving an anti-counterfeiting function. Furthermore, since the identifier is visible to the naked eye and easily seen, combined with the different information represented by the identifier, when a product malfunctions, customers can confirm product attributes and other relevant information based on the different identifiers, without needing to read chip information or query processing history, achieving rapid confirmation of product attributes and other relevant information.

[0022] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.
[0023] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.
[0024] See Figure 1 and Figure 3This application discloses a carrier tape for a smart card module. The carrier tape for the smart card module includes an identifier 103. The identifier 103 is visible to the naked eye and can be formed on any visible layer of the carrier tape. In an embodiment of this application, the identifier 103 is formed on a conductive layer 1, and more specifically, the conductive layer 1 is a copper foil. Some smart card carrier tapes include one of the following layers: a cover layer / protective film, a printed layer, or a surface treatment layer, etc., and the identifier 103 can also be formed on the cover layer / protective film, the printed layer, or the surface treatment layer, etc. The identifier 103 includes multiple graphics to represent product attribute and other related information, such as the relevant manufacturer (here, relevant manufacturers typically include chip manufacturers, carrier tape manufacturers, smart card module manufacturers, and packaging and testing manufacturers, but may also include other manufacturers, and not necessarily all manufacturers). Product attribute and other related information may also include production date, production batch, etc. The number of graphics can be determined arbitrarily; it can be less than, equal to, or more than the number of manufacturers. For example, one graphic can be associated with one manufacturer, several graphics can be associated with one manufacturer, or the relationship between graphics (such as the size or distance relationship described later) can be associated with one manufacturer. For example, assume that the multiple graphics correspond to a string. The string has six characters: the first and second characters represent the chip manufacturer, the third character represents the carrier tape manufacturer, the fourth and fifth characters represent the smart card module manufacturer, and the sixth character represents the packaging and testing manufacturer. The graphics can be understood as a visual form composed of elements such as points, lines, surfaces, and numbers in two-dimensional space. For example, if the multiple patterns include points and lines, then the identifier 103 can be Morse code. For example, in Morse code, two dots followed by a dash and a dot represent the letter F (e.g., representing the chip manufacturer), two dots represent the letter I (e.g., representing the carrier tape manufacturer), four dots represent the letter H (e.g., representing the packaging and testing manufacturer), and a dot followed by two dashes and a dot represents L (e.g., representing the smart card module manufacturer). When the pattern consists of points and lines, the points can be black dots (filled circles) or circular dots (unfilled circles). The lines can be dashed or solid, and of course, include variations in line thickness. For example, if the multiple patterns are the logos of the relevant manufacturers, the identifier can be a QR code containing the logo. Essentially, this method uses a specific graphic to represent a particular manufacturer. In short, the composition of the identifier 103 is not limited, as long as it allows information such as product attributes (e.g., the relevant manufacturer) to be obtained without needing to investigate the manufacturing history or read chip information.
[0025] As described above, since the identifier includes multiple graphics, the information corresponding to the identifier enables product identification and traceability, thus serving an anti-counterfeiting function. Furthermore, because the identifier 103 is visually visible and easily seen, and considering the different information represented by the identifier 103, when a product malfunctions, customers can confirm relevant information such as product attributes (e.g., which manufacturers are involved, thereby further clarifying the malfunction or which products are affected) based on the different identifiers 103, without needing to read chip information or query processing history, achieving rapid confirmation of product attributes and other relevant information.
[0026] Please see Figure 1 and Figure 3 The conductive layer 1 has contacts 102 for connecting to the chip and the marking 103. The conductive layer 1 is divided into a plurality of contacts 102 by etching lines 101, and the etched contacts 102 conform to the ISO7816 protocol. Figure 1 dashed box and Figure 4 Six contacts 102 are shown (labeled as first contact 1021, second contact 1022, third contact 1023, fourth contact 1024, fifth contact 1025, and sixth contact 1026 for easy distinction), but the number of contacts 102 is not limited to this. The conductive layer 1 in this embodiment is copper foil, but the material of the conductive layer 1 is not limited. The carrier tape for the smart card module includes a base fabric 2, on which the conductive layer 1 is formed. The formation method is not limited; for example, the conductive layer 1 can be formed on the base fabric 2 by bonding to constitute the carrier tape for the smart card module. The base fabric 2 serves as a connector and insulator, and is punch-cut with solder pad holes 201 and serrated holes 202. The solder pad holes 201 are used for soldering wires to the contacts 102, realizing the connection between the chip and the contacts 102. The serrated holes 202 are used for stepping the carrier tape for the smart card module, for example, stepping in the direction indicated by arrow R, for processing. Those skilled in the art will understand that the embodiments described in this application can be applied to carrier tapes for smart card modules of any structure.
[0027] As described above, the contact 102 and the mark 103 are formed through the conductive layer 1, which facilitates the formation of the mark 103. For example, the contact 102 and the mark 103 can be formed by etching the conductive layer 1.
[0028] See Figure 1 and Figure 3 The plurality of graphics in the identifier 103 constitute Morse code (the graphics can form patterns, also known as Morse patterns). Morse code consists of dots and lines (dashes). Dots and lines can be circles and lines (such as straight lines), or see [reference needed]. Figure 1 and Figure 2One shape represents a dot, and another shape represents a line (dash). Here are some examples of Morse code representations of the identifier 103: two dots followed by a dash and a dot represent the letter F (e.g., a chip manufacturer); two dots represent the letter I (e.g., a carrier tape manufacturer); a dot followed by two dashes and a dot represents the letter L (e.g., a smart card module manufacturer); and four dots represent the letter H (e.g., a packaging and testing manufacturer).
[0029] As described above, since the multiple graphics constitute Morse code, on the one hand, customers can confirm relevant information such as product attributes (e.g., related manufacturers) based on the Morse code, which is convenient. On the other hand, Morse code can be composed of simple graphics, making the multiple graphics simple and easy to manufacture (e.g., easy to form graphics through etching).
[0030] See Figure 1 and Figure 2 All the graphics of the identifier 103 are formed at the same contact point. Figure 1 and Figure 2 The identifier 103 shown consists of two graphics; more specifically, the first graphic is a first notch 1031, and the second graphic is a second notch 1032. Depending on the function of the identifier 103, in other embodiments, the identifier 103 can be formed on any one of the plurality of contacts 102 of the conductive layer; more specifically, the identifier 103 can be formed on any one of the first contact 1021, the second contact 1022, the third contact 1023, the fourth contact 1024, the fifth contact 1025, and the sixth contact 1026.
[0031] As described above, all the graphics of the logo 103 are formed on the same contact point, so customers can find the logo 103 in one place, which is convenient for confirmation; furthermore, the logo 103 only needs to be processed in one place (on one contact point), which is convenient for manufacturing the logo 103.
[0032] See Figure 1 and Figure 4 The identifier 103 is formed at the contact point with the largest area. For example... Figure 1 As shown, contact 102 includes a first contact 1021, a second contact 1022, a third contact 1023, a fourth contact 1024, a fifth contact 1025, and a sixth contact 1026. The first contact 1021 has the largest area, and the identifier 103 is formed on the first contact 1021.
[0033] As described above, the mark 103 is formed on the contact with the largest area. The largest area provides more space, which facilitates manufacturing (e.g., etching) and allows the mark 103 to be relatively large, clear, and easy to identify. Furthermore, it prevents damage to other structures during the formation of the mark 103. For example, the mark 103 can be relatively far from the connection area 104 without damaging its structure, which helps improve yield and avoids affecting the product's electrical performance. In some embodiments, the mark 103 can also be formed on the grounding contact, in which case the contact with the largest area serves as the grounding contact. Of course, the grounding contact does not necessarily have to be the contact with the largest area 102.
[0034] See Figure 4 The contact 102 is provided with a connection area 104 for connecting to the chip. The identifier 103 is separate from the connection area 104 and are two independent parts on the contact 102.
[0035] As described above, after the identifier 103 is separated from the connection area 104, there is no connection between them and they are a certain distance apart. Therefore, the identifier 103 will not affect the connection between the connection area 104 and the chip, etc., and the product has good electrical performance.
[0036] See Figure 1 , Figure 2 and Figure 4 The identifier 103 is formed on the edge of the contact 102. In this embodiment, it is not limited to the edge of the contact 102 with the largest area; for example, it can also be formed on the edge of the second contact 1022, the edge of the third contact 1023, the edge of the fourth contact 1024, the edge of the fifth contact 1025, or the edge of the sixth contact 1026. The edge can also be the edge of any side of the contact 102.
[0037] As described above, since the mark 103 is formed on the edge of the contact 102, it is more conducive to avoiding damage to the structure of the contact 102 by the mark 103, and it is also farther away from the connection area 104, resulting in better electrical performance of the product.
[0038] See Figure 1 , Figure 2 and Figure 4 The multiple graphics of the identifier 103 are all notches. Figure 1 , Figure 2 and Figure 4 The illustrations all depict eight notches. The shape of the notches is not limited; they can be U-shaped, C-shaped, trapezoidal, etc. Of course, technical personnel will understand that as long as some of the figures in the multiple figures are notches, it is acceptable.
[0039] As described above, when the mark 103 is located at the edge of the contact point 102, at least some of the multiple graphics are notches. The notches occupy a small area, which makes it easier to manufacture the notches. On the other hand, the area of the notches in contact with the human body is small, and the area of the product in contact with the human body and other industrial products is small, which helps to reduce the risk of the product being corroded by sweat, hydrochloric acid, etc.
[0040] See Figure 1 , Figure 2 and Figure 4 The notch includes at least one of the following features:
[0041] a) The shapes of the notches are not the same. Figure 1 , Figure 2 and Figure 4 The diagram illustrates a first notch 1031 and a second notch 1032 with different shapes. When the multiple shapes of the identifier 103 constitute Morse code, the first notch 1031 can represent a dot in Morse code, and the second notch 1032... The number of notches is not limited to... Figure 1 , Figure 2 and Figure 4 The two shown can be three, four, etc. Different shapes include the following: a) The two shapes are similar, for example, both gaps are C-shaped, but the sizes are not equal; b) The two shapes are completely different, for example, one gap is C-shaped and the other gap is U-shaped.
[0042] As described above, since the identifier 103 is composed of notches of different shapes, these different shapes can also serve as an element constituting the identifier. For example, the first notch 1031 represents manufacturer A, the second notch 1032 represents manufacturer B, and if the shapes of the first notch 1031 and the second notch 1032 are different, it represents manufacturer C. Thus, two notches represent three manufacturers, and so on. Ultimately, the number of graphics is less than the number of manufacturers. Therefore, the above design helps to reduce the number of graphics, facilitating the manufacturing of the carrier tape for the smart card module. Alternatively, it could be as follows... Figure 1 , Figure 2 and Figure 4 In this way, these gaps correspond to a string of information. During production, the product attributes and other relevant information associated with this string can be agreed upon in advance (such as which manufacturers). Customers can identify which manufacturers it is by seeing the string.
[0043] b) The distances between the notches are not equal. In this case, referring to the previous description of different notch shapes, the unequal distances between the notches can also be an element constituting the identifier 103. This design is beneficial for reducing the number of graphics and facilitating the manufacture of the carrier tape for the smart card module.
[0044] c) See also Figure 2 and Figure 4 The notch includes at least one of a first notch 1031 and a second notch 1032. The first notch 1031 is an arc-shaped notch, which includes a notch formed by a circular arc, such as a C-shaped notch. The second notch 1032 includes a first sidewall 10321 and a second sidewall 10322; the first sidewall 10321 is along a direction perpendicular to the stepping direction of the carrier tape of the smart card module (see...). Figure 1 The first sidewall 10321 extends perpendicular to the direction of arrow R; the two second sidewalls 10322 extend along the stepping direction respectively, located at the opposite ends of the first sidewall 10321, and are connected to the first sidewall 10321 by chamfering.
[0045] As described above, since the first notch 1031 is an arc-shaped notch, the second notch 1032 includes a first sidewall 10321 and a second sidewall 10322. The first sidewall 10321 extends along the stepping direction perpendicular to the carrier tape of the smart card module, and the second sidewall 10322 extends along the stepping direction. The first sidewall 10321 and the second sidewall 10322 are connected by a chamfer. In this way, the sidewalls of the first notch 1031 and the second notch 1032 are smooth, without burrs, etc., and are not easy to scratch people.
[0046] See Figure 1 In a direction perpendicular to the direction of the smart card module's tape stepping, all the identifiers 103 are located on the side of the contact 102 along the stepping direction. See also Figure 1 The diagram illustrates four identifiers 103, distributed along the first side 21 in the stepping direction. Each of these four identifiers 103 is located on a corresponding contact 102, on the same side as the first side 21. In other embodiments, all identifiers 103 may also be located on the side of the contact 102 in the opposite direction of the stepping direction; that is, each identifier 103 is located on a corresponding contact 102, on the same side as the second side 22. The smart card module carrier tape includes multiple... Figure 1 As shown, the entire smart card module uses a carrier tape to... Figure 1 The shown portion can be repeated. In this embodiment, the identifier 103 can be formed on the conductive layer 1 (copper foil) located on the base fabric 2, or it can be formed on the conductive layer 1.
[0047] As described above, since all the markings 103 are located on the same side of the carrier tape as the first side 21 or the second side 22, it is convenient to manufacture the markings 103.
[0048] Secondly, this application discloses a smart card module. The smart card module includes any of the aforementioned smart card module carrier tapes.
[0049] Thirdly, this application discloses a smart card. The smart card includes any of the aforementioned smart card modules.
[0050] Both the smart card and the smart card module have the beneficial effects brought by the carrier tape of the smart card module. For example, the manufacturer and other information can be quickly identified based on the identifier, thereby enabling rapid product information confirmation.
[0051] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
