<Peeling sheet with IC tag adhesive and IC tag adhesive>
First, the IC tag pressure-sensitive adhesive release sheet 14 and the IC tag pressure-sensitive adhesive body 12 will be described mainly with reference to FIGS. Moreover, after explaining these, the peeling sheet 14a with an interposer adhesive body and the interposer adhesive body 12a are demonstrated.

  As shown in FIG. 1 and FIG. 2, the IC tag pressure-sensitive adhesive release sheet 14 is electrically connected to the base material 30, the antenna 34 formed on the base material 30, and the antenna 34. The IC tag 10 having the protruding IC chip 32, the release sheet 45 on which one surface 46 is peeled off, the surface 46 on which the release sheet 45 is peeled off, and the IC chip 32 of the IC tag 10 And an adhesive layer 40 interposed between the protruding surface and the surface. In addition, through holes 47 and 42 for receiving the IC chip 32 from which the IC tag 10 protrudes are formed in the release sheet 45 and the adhesive layer 40.

  On the other hand, the IC tag adhesive body 12 includes the above-described IC tag 10 and the adhesive layer 40 attached to the surface of the IC tag 10 on which the IC chip 32 protrudes. Such an IC tag pressure-sensitive adhesive body 12 is obtained by removing the release sheet 45 from the release sheet 14 with an IC tag pressure-sensitive adhesive body. As described above, since the surface 46 facing the adhesive layer 40 of the release sheet 45 is subjected to the release treatment, the adhesive layer 40 is fixed to the IC tag 10 with a stronger adhesive force (adhesive force) than the release sheet 45. Has been. Therefore, when the IC tag 10 is peeled off from the release sheet 45, the adhesive layer 40 is peeled off from the release sheet 40 together with the IC tag 10 while being attached to the IC tag 10. That is, a so-called seal-like IC tag pressure-sensitive adhesive body 12 can be obtained from the release sheet 14 with the IC tag pressure-sensitive adhesive body, and the obtained IC tag pressure-sensitive adhesive body 12 can be directly pasted to the object to be pasted through the pressure-sensitive adhesive layer 40. .

  Hereinafter, the details of the release sheet 14 with the IC tag pressure-sensitive adhesive body and the IC tag pressure-sensitive adhesive body 12 will be described.

First, the IC tag 10 will be described.
The IC tag 10 is connected to an external device (reader / writer, etc.) (not shown) that emits electromagnetic waves for communication, or is brought into physical contact (not an electrical connection) via an antenna 34. Transmission / reception of information, for example, reading of information recorded on the IC chip 32 of the IC tag 10, writing or correction of information on the IC chip 32, and the like can be performed. Therefore, an IC circuit for performing at least such a function is written in the IC chip 32.

  As shown in FIG. 2, the IC chip 32 protrudes from the lower surface of the IC chip body 33a in which the IC circuit is written, and is electrically connected (conducted) to the IC circuit of the IC chip body 33a. And a pair of connection electrodes (also called bumps) 33b and 33b.

  On the other hand, the antenna 34 electrically connected to the IC chip 32 is supported on a nonconductive base material 30 made of, for example, paper or PET. The antenna 34 is formed by, for example, applying a conductive ink on the base material 30 using a screen printer, or transferring a conductive foil made of copper, aluminum, or the like on the base material, or on the base material. The conductive foil made of copper, aluminum, or the like formed on the substrate is etched and patterned into a desired shape, so that it can be formed on the substrate 30. In addition, the shape of the base material 30 facing the antenna 34 is not particularly limited as long as the antenna 34 can be stably supported, and various shapes can be employed.

  In the example shown in FIGS. 1 and 2, the antenna 34 is formed of a pair of substantially rod-shaped conductors, and functions as a so-called dipole antenna. As shown in FIG. 2, the IC chip 32 is disposed on the antenna 34 such that the connection electrode 33 b faces the antenna 34. The IC chip 32 is fixed on the antenna 34 with an adhesive (not shown) or the like, and protrudes on the substrate 30 by the thickness of the IC chip 32 itself. The pair of connection electrodes 33b and 33b of the IC chip 32 are electrically connected to a pair of conductors forming the antenna 34, respectively. This electrical connection can be achieved by various methods, for example, by simple contact between the connection electrode 33b and the antenna 34, or by ultrasonic bonding, or an adhesive. It may be a connection via.

  An adhesive layer 40 having a substantially uniform thickness is attached to the surface of the IC tag 10 having such a configuration on the side where the IC chip 32 is disposed. As shown in FIGS. 1 and 2, the adhesive layer 40 has a through hole 42, and the IC chip 32 from which the IC tag 10 protrudes is accommodated (arranged) in the through hole 42. Therefore, such an adhesive layer 40 is a flat antenna 34 formed on a region where the IC chip 32 is not disposed on the surface of the IC tag 10 where the IC chip 32 is disposed, that is, on the base material 30. Located mainly on the top. Therefore, the adhesive layer 40 is firmly and stably attached (fixed or fixed) on the IC tag 10 by its own adhesive force (adhesive force).

  The release sheet 45 provided on the adhesive layer 40 has a substantially uniform thickness, and is made of, for example, paper or PET. As described above, the surface of the release sheet 45 facing the pressure-sensitive adhesive layer 40 is subjected to a release process, and this release process is performed, for example, by applying silicon particles to the surface of paper or PET. By this peeling treatment, the adhesive force (adhesive force) of the adhesive layer 40 to the release sheet 45 is reduced.

  As shown in FIGS. 1 and 2, a through-hole 47 is also formed in the release sheet 45. The through holes 47 of the release sheet 45 are continuously arranged adjacent to the through holes 42 of the adhesive layer 40 and communicate with each other. Therefore, the IC chip 32 from which the IC tag 10 protrudes is accommodated (arranged) in the through hole 47.

  The thickness of the IC chip 32 of the IC tag 10 is preferably equal to or less than the thickness of the laminate 20 of the release sheet 45 and the adhesive layer 40 or less than the thickness of the laminate 20, and the thickness of the IC chip 32 is preferably the adhesive layer. More preferably, the thickness is 40 or less or less than the thickness of the laminated layer 40. When the thickness of the IC chip 32 is equal to or less than the thickness of the adhesive layer 40, the IC chip 32 provided on the antenna 34 of the IC tag 10 is completely placed in the release sheet 45 and the through holes 47 and 42 of the adhesive layer 40. When the thickness of the IC chip 32 is equal to or less than the thickness of the adhesive layer 40, the IC chip 32 can be completely accommodated in the through hole 42 of the adhesive layer 40.

  According to the release sheet 14 with the IC tag pressure-sensitive adhesive body in this embodiment, the protruding IC chip 32 is disposed in the through holes 47 and 42 provided in the release sheet 45 and the pressure-sensitive adhesive layer 40. The protrusion amount of the IC chip 32 in the IC tag 10 can be reduced by at least the total thickness of the release sheet 45 and the adhesive layer 40. Therefore, when the peeling sheet 14 with the IC tag pressure-sensitive adhesive body is overlapped or wound up, the package can be stabilized and the load applied to the IC chip 32 can be remarkably reduced. Moreover, since the unevenness | corrugation (undulation, level | step difference) of the base material 30 surface is suppressed at least, manufacture information etc. can also be correctly written in this base material 30 surface. Furthermore, the IC tag 10 can be easily peeled off from the release sheet 45 together with the adhesive layer 40, and the IC tag 10 can be directly attached to the pasting object via the adhesive layer 40. In this case, since the protruding IC chip 32 is disposed in the through hole 42 provided in the adhesive layer 40, the protruding amount of the IC chip 32 can be absorbed by at least the thickness of the adhesive layer. The IC tag 10 can be stuck to the sticking object more firmly and stably.

  Further, according to the IC tag pressure-sensitive adhesive body 12 in this embodiment, since the protruding IC chip 32 is disposed in the through hole 42 provided in the pressure-sensitive adhesive layer 40, at least the thickness of the pressure-sensitive adhesive layer 40. Only the protrusion amount of the IC chip 32 can be reduced. Thereby, the IC tag 10 can be more firmly and stably attached to the object to be attached. In addition, since unevenness (swells, steps) on the surface of the base material 30 in the state where the IC tag 10 is attached to the object to be applied is at least suppressed, writing of manufacturing information and the like on the surface of the base material 30 can be performed accurately. it can.

This is different from the embodiment shown in FIG. 1 and FIG. In the present modification shown in FIG. 4, the bridge 35 has a bridge conductor 37 such as a metal plate fixed on the base material 30 via an adhesive layer 39. The bridge conductor 37 is electrically connected to the antenna 34 formed on the substrate 30 via, for example, a silver paste 29 or the like. In the first modification of the IC tag 10 as described above, as shown in FIGS. 4 and 5, the bridge 35 (bridge conductor 37) is provided separately from the through holes 42 and 47 that receive the IC chip 32. Receiving through holes 42 and 47 are provided in the adhesive layer 40 and the release sheet 45. Accordingly, these through holes 47 and 42 accommodate not only the IC chip 32 but also the bridge 35 (bridge conductor 37). In this case, the thickness of the bridge 35, at least the bridge conductor 37, is preferably equal to or less than the thickness of the laminate 20 of the release sheet 45 and the adhesive layer 40 or less than the thickness of the laminate 20. More preferably, the electrical conductor 37 has a thickness equal to or less than the thickness of the adhesive layer 40 or less than the thickness of the adhesive layer 40.

  The above-described configuration of the bridge 35 having the bridge conductor 37 and the connection method to the antenna 34 are merely examples, and various known configurations of the bridge 35 and connection methods to the antenna 34 may be adopted. it can.

  On the other hand, in the second modification shown in FIGS. 6 and 7, an interposer adhesive body 12a having an interposer 10a and an adhesive layer 40 attached to the interposer 10a is provided on the antenna 34 of the IC tag 10. 1 and 2 and the modification shown in FIGS. 3 to 5.

  According to the first and second modifications as described above, the protrusions of the interposer 10a and the bridge 35 in the IC tag 10 can also be reduced by the through holes 47 and 42. Therefore, when the peeling sheet 14 with the IC tag pressure-sensitive adhesive body is overlapped or wound up, the load can be stabilized, and the load applied to the IC chip 32, the interposer 10a including the IC chip 32, and the bridge 35. Can be greatly reduced. Also, manufacturing information and the like can be accurately written on the surface of the substrate 30.

In addition, since the unevenness (swells, steps) on the surface of the base material 30 in the state where the interposer 10a is pasted on the antenna 34 is suppressed at least, manufacturing information and the like can be accurately written on the surface of the base material 30. .

  In the example shown in FIG. 1, the release sheet 14 a with an interposer pressure-sensitive adhesive body is provided with a plurality of interposers 10 a that are adhesively held on the release sheet 45 via separate adhesive layers 40. However, the present invention is not limited to this, and the interposer pressure-sensitive adhesive release sheet 14a may include only one interposer 10a.

<Method for producing release sheet with IC tag pressure-sensitive adhesive body, and material for release sheet with IC tag pressure-sensitive adhesive body and method for producing the same>
Next, mainly using FIG. 8 thru | or FIG. 14 and FIG. 14, the manufacturing method of the peeling sheet 14 with an IC tag adhesive body, and the release sheet material 16 with an IC tag adhesive body used for the IC sheet adhesive release sheet 14 The manufacturing method thereof will be described. Moreover, after explaining these, similarly, the manufacturing method of the release sheet 14a with an interposer adhesive body, the material 16a for release sheets with an interposer adhesive body used for the release sheet 14a with an interposer adhesive body, and its manufacturing method are demonstrated.

  FIG. 14 is a schematic view showing a method for producing the release sheet 14 with an IC tag pressure-sensitive adhesive body. FIG. 14 shows an example in which an IC tag pressure-sensitive adhesive release sheet 14 including an IC tag 10 having an antenna 34 made of a pair of substantially rod-shaped conductors shown in FIGS. 1 and 2 is manufactured. Therefore, in the manufacturing method shown in FIG. 14 and described below, the size of the conductor (antenna 34) is appropriately changed to provide an interposer 10a that can have the same configuration except for the size of the conductor. Naturally, the release sheet 14a with the interposer pressure-sensitive adhesive body can be produced by the same method.

  When manufacturing the peeling sheet 14 with an IC tag pressure-sensitive adhesive body, first, a sheet-like base material 31 that extends in a strip shape, and an antenna that is provided on the sheet-like base material 31 to form a plurality of antennas 34 by cutting or as they are. A sheet with an IC tag (also referred to as an IC tag material) having a conductor 36 and a plurality of IC chips 32 that are electrically connected to the antenna conductor 36 on the sheet substrate 31 and project from the sheet substrate 31. 24) Prepare and send in 24. In addition, such a sheet | seat 24 with an IC tag can be manufactured by the method etc. which were disclosed by patent document 1 (Unexamined-Japanese-Patent No. 2005-63201) mentioned above, for example.

  An example of a sheet with an IC tag is shown in FIGS. 8 and 9, and FIGS. 10 and 11. The IC tag-attached sheet 24 shown in FIGS. 8 and 9 has a plurality of pairs of antenna conductors 36 arranged along the longitudinal direction of the sheet-like base material 31, and each pair of antenna conductors 36. , 36 are connected to the IC chip 32 as they are to form the antenna 34. On the other hand, the IC tag-attached sheet 24 shown in FIGS. 10 and 11 has a pair of antenna conductors 36 that extend along the longitudinal direction of the sheet-like base material 31 and are spaced apart from each other. The antenna conductor 36 shown in FIGS. 10 and 11 is cut, for example, along the width direction perpendicular to the longitudinal direction (for example, cut along the L1 line in FIG. 10). Alternatively, by cutting into a circumferential shape surrounding the IC chip 32 (for example, by cutting along the L2 line in FIG. 10), a pair of substantially rod-shaped antennas 34 is formed.

  FIG. 14 shows a method for manufacturing the IC tag pressure-sensitive adhesive release sheet 14 using the IC tag-attached sheet 24 shown in FIGS. 10 and 11.

  As will be described later, the sheet-like substrate 31 is cut or the like to form the substrate 30 of the IC tag 10. Therefore, the sheet-like base material 31 is made of, for example, non-conductive PET or paper. Moreover, the shape of the sheet-like base material 31 is not particularly limited as long as the antenna conductor 36 can be supported.

  As shown in FIG. 14, in parallel with the feeding of the IC-tagged sheet 24, at least one surface was laminated on the release sheet 45 on which the release process was performed and the surface 46 on which the release process of the release sheet 45 was performed. The laminate 20 having the adhesive layer 40 is prepared and fed. As the laminated body 20, for example, a double-sided tape that is distributed in a wound state and can be obtained at low cost can be used. When the pressure-sensitive adhesive layer 40 is formed by applying a pressure-sensitive adhesive (adhesive) or by a pressure-sensitive adhesive sheet separated from the release sheet 45, the pressure-sensitive adhesive or the pressure-sensitive adhesive sheet is prevented from adhering to devices or products arranged around the adhesive layer 40. However, according to the present embodiment, since the adhesive layer 40 is handled as the laminate 20 with the release sheet 45, such complexity can be eliminated, and it is efficient and easy. A release sheet 14 with an IC tag pressure-sensitive adhesive body can be produced. However, the pressure-sensitive adhesive layer in the present application does not exclude a pressure-sensitive adhesive layer formed by the pressure-sensitive adhesive sheet separated from the application of the pressure-sensitive adhesive or the release sheet.

  After that, as shown in FIG. 14, the through-holes 47 and 42 correspond to the arrangement of the IC chips 32 in the sheet-like base material 31 of the sheet 24 with IC tag in the peeled sheet 45 and the adhesive layer 40 of the fed laminate 20. Are formed sequentially. In the present embodiment, the through holes 47 and 42 are formed by the punching device 60. However, the through holes 47 and 42 may be formed by a device other than the punching device 60, for example, a drill or the like.

  Next, the sheet 24 with the IC tag and the laminated body 20 that are fed in face the surface of the IC tag-attached sheet 24 on which the IC chip 32 is disposed and the surface of the laminated body 20 on the adhesive layer 40 side. At the same time, the IC chip 32 is superposed by the nip roller 64 so that the IC chip 32 is disposed in the through holes 42 and 47 of the laminate 20. The stacked IC tag-attached sheet 24 and the laminated body 20 are bonded and fixed to each other by the adhesive force of the adhesive layer 40.

  Through the steps so far, the IC tag-attached sheet 24 shown in FIG. 8 and FIG. 9 or FIG. 10 and FIG. The surface on which the IC chip 32 of the sheet 24 with IC tag protrudes (the surface of the sheet-like substrate 31 on which the IC chip protrudes, and the antenna conductor 36 formed on the surface). An adhesive layer 40 interposed between the adhesive sheet 40 and the release sheet 45, and a release sheet with an IC tag adhesive body in which through holes 42 and 47 for receiving the IC chip 32 protruding from the adhesive layer 40 are formed. Material 16 is obtained.

  Then, the cut | notch 50 which penetrates the adhesion layer 40 of the laminated body 20 from the IC tag adhesion body release sheet material 16 side of the IC tag adhesion body release sheet material 16 to the release sheet 45 is formed. The notch 50 is formed for each IC chip 32 along, for example, the L1 line and the L2 line in FIG. 10 described above, and individual antennas 34 are formed from the antenna conductor 36. Thereby, the IC tag 10 having the base material 30, the antenna 34, and the IC chip 32 connected to the antenna 34 and supported on the stacked body 20 is sequentially manufactured. In the present embodiment, the notch forming device 70 for forming the notch 50 includes a notch blade 71 along the contour of the desired IC tag 10 and a receiving member 72 arranged to face the notch blade 71. Have. The cutting blade 71 can move forward and backward toward the receiving member 72. The cutting blade 71 moves toward the receiving member 72 in a state where the IC tag pressure-sensitive adhesive sheet 16 is sandwiched between the cutting blade 71 and the receiving member 72, and penetrates the IC tag-attached sheet 24 and the pressure-sensitive adhesive layer 40. At the same time, the sheet is cut to the release sheet 45 but does not penetrate the release sheet 45 (FIG. 14).

  Next, the portion 25 other than the portion forming the IC tag 10 of the IC tag-attached sheet 24 is peeled off from the release sheet 45 together with the adhesive layer 40 facing the portion 25 and removed. Thereby, the peeling sheet 14 with an IC tag adhesive body is obtained.

  According to such a manufacturing method of the release sheet 14 with the IC tag pressure-sensitive adhesive body, the release sheet 14 with the IC tag pressure-sensitive adhesive body is manufactured using the laminate 20 having the release sheet 45 and the pressure-sensitive adhesive layer 40. The adhesive layer 40 that is difficult to handle can be easily handled as a part of the laminate 20. Moreover, by providing the through holes in the laminate 20, the through holes 47 and 42 aligned with each other can be formed in the release sheet 45 and the adhesive layer 40 at a time. Furthermore, as the laminate 20, a double-sided tape or the like that is generally widely used and available at a low cost can be used. Therefore, it is possible to inexpensively and efficiently manufacture the high-quality IC tag pressure-sensitive adhesive release sheet 14 in which the protruding IC chip 32 is disposed in the through holes 47 and 42 provided in the release sheet 45 and the adhesive layer 40. it can.

  As described above, the IC tag pressure-sensitive adhesive release sheet material 16 is obtained during the manufacturing process of the IC tag pressure-sensitive adhesive release sheet 14. As shown in FIG. 15, the IC tag pressure-sensitive adhesive release sheet 14 can be obtained simply by cutting the IC tag pressure-sensitive adhesive release sheet material 16 for each IC chip 32. Further, according to the release sheet 14 with the IC tag pressure-sensitive adhesive body obtained from the release sheet material 16 with the IC tag pressure-sensitive adhesive body, the IC tag 10 can be easily peeled off from the release sheet 45 together with the pressure-sensitive adhesive layer 40. The IC tag 10 can be attached as it is through the adhesive layer 40. In this case, since the protruding IC chip 32 is disposed in the through hole 42 provided in the adhesive layer 40, the protruding amount of the IC chip 32 can be reduced by at least the thickness of the adhesive layer 40. The IC tag 10 can be more firmly and stably attached to the object to be attached.

  Therefore, according to conditions and conditions such as the shape and production quantity of the IC tag to be manufactured, the IC tag pressure-sensitive adhesive sheet with release sheet 16 is manufactured by the manufacturing method described above, and if necessary, cutting means The IC tag pressure-sensitive adhesive release sheet material 16 may be cut by 74 to obtain individual IC tag pressure-sensitive adhesive release sheets 14. Note that the IC tag pressure-sensitive adhesive release sheet material 16 has the same effects as the IC tag pressure-sensitive adhesive release sheet 14. That is, according to the IC tag pressure-sensitive adhesive release sheet material 16 as described above, since the protruding IC chip 32 is disposed in the through holes 47 and 42 provided in the release sheet 45 and the pressure-sensitive adhesive layer 40, at least The protrusion amount of the IC chip 32 can be reduced by the total thickness of the release sheet 45 and the adhesive layer 40. Therefore, when the release material 16 with the IC tag pressure-sensitive adhesive body is stacked or wound up, the package can be stabilized and the load applied to the IC chip 32 can be remarkably reduced. Also, manufacturing information and the like can be accurately written on the surface of the sheet-like substrate 31.

  Further, according to the manufacturing method described above, the release sheet 14 with the IC tag pressure-sensitive adhesive body shown in FIGS. 3 to 5 and FIGS. 6 and 7 and the release sheet 14 with the IC tag pressure-sensitive adhesive body shown in FIGS. Each of the release sheet materials 16 with IC tag pressure-sensitive adhesive body shown can be produced.

  However, when the IC tag pressure-sensitive adhesive release sheet 14 shown in FIG. 3 to FIG. 5 or the IC tag pressure-sensitive adhesive release material 16 shown in FIG. 12 is manufactured, as shown in FIG. The antenna conductor 36 has a coiled portion that forms a coil shape, and a bridge conductor 37 that short-circuits the innermost and outermost periphery of the coiled portion. In addition, the punching device 60 uses the laminated body 20 for the bridge 35 (bridge conductor 37) corresponding to the arrangement of the bridge 35 (bridge conductor 37) on the sheet-like substrate 31 of the sheet 24 with IC tag. The through holes 42 and 47 are further formed. In this way, the release sheet 14 with an IC tag pressure-sensitive adhesive body shown in FIGS. 3 to 5 can be produced, and the release sheet material 16 with an IC tag pressure-sensitive adhesive body shown in FIG. 12 can also be produced.

  On the other hand, when the release sheet 14 with the IC tag pressure-sensitive adhesive body shown in FIGS. 6 and 7 or the release sheet material 16 with the IC tag pressure-sensitive adhesive body shown in FIG. 13 is manufactured, as shown in FIG. An IC tag-attached sheet 24 in which an interposer 10a having an IC chip 32 is disposed is prepared. Moreover, the through-hole which can arrange | position the interposer 10a containing the connection member 34a in the laminated body 20 by the punching apparatus 60 corresponding to arrangement | positioning of the interposer 10a on the sheet-like base material 31 of the sheet | seat 24 with an IC tag. 42 and 47 are formed. In this way, the release sheet 14 with an IC tag pressure-sensitive adhesive body shown in FIGS. 6 and 7 can be manufactured, and the release sheet material 16 with an IC tag pressure-sensitive adhesive body shown in FIG. 13 can also be manufactured.

  In such a modification, the protrusions of the interposer 10a and the bridge 35 in the IC tag 10 can also be reduced by the through holes 47 and 42. Therefore, when the IC tag pressure-sensitive adhesive release sheet 14 or the IC tag pressure-sensitive adhesive sheet 16 is stacked or wound, the package can be stabilized, and the IC chip 32 and the IC chip 32 are included. The load applied to the interposer 10a and the bridge 35 can be remarkably reduced. In addition, manufacturing information and the like can be accurately written on the surface of the base material 30 (the surface of the sheet-like base material 31). Further, when the IC tag 10 is attached to the object to be attached via the adhesive layer 40, not only the IC chip 32 but also the interposer 10 a and the bridge 35 protruding from the base material 30 are provided in the through hole 42 provided in the adhesive layer 40. Therefore, the amount of protrusion can be reduced by at least the thickness of the adhesive layer, whereby the IC tag 10 can be more firmly and stably attached to the object to be attached.

<Method for producing release sheet with interposer pressure-sensitive adhesive body, and material for release sheet with interposer pressure-sensitive adhesive body and method for producing the same>
Furthermore, as described above, except for the difference in the size of the conductor based on the difference in the use of the conductor connected to the IC chip 32, it is the same as the IC tag 10 having a pair of substantially rod-shaped antennas. The configuration can be adopted for the interposer 10a. Therefore, as mentioned at the beginning of the description of the manufacturing method, the release sheet 14a with the interposer pressure-sensitive adhesive body can be manufactured by the manufacturing method shown in FIG. 14, and accordingly, the manufacturing shown in FIG. The release sheet material 16a with an interposer pressure-sensitive adhesive body can be produced by the method.

  Hereinafter, the manufacturing method of the release sheet 14a with an interposer pressure-sensitive adhesive body, the release sheet material 16a with an interposer pressure-sensitive adhesive body, and the manufacturing method thereof will be mainly described with reference to FIGS. The same parts as those described above for the manufacturing method of the IC tag pressure-sensitive adhesive release sheet 14 and the IC tag pressure-sensitive adhesive sheet 16 and the manufacturing method thereof will be denoted by the same reference numerals, and detailed description will be repeated. Omitted.

  As shown in FIGS. 14 and 15, the release sheet 14a with an interposer pressure-sensitive adhesive body and the release sheet material 16a with an interposer pressure-sensitive adhesive body are manufactured as follows.

  First, a sheet-like base material 31 that extends in a band shape, a connection member conductor 36a that is provided on the sheet-like base material 31 and that is cut or directly forms a plurality of connection members 34a, and the sheet-like base material 31 A sheet with an interposer (also referred to as an interposer material) 24a (FIGS. 8 to 10) having a plurality of IC chips 32 electrically connected to the connecting member conductor 36a and protruding from the sheet-like base material 31 is prepared. Then send it in. The sheet 24a with an interposer is sized according to the use of the above-described sheet 24 with an IC tag and the conductors (antenna conductor 36 and connecting member conductor 36a) connected to the IC chip 32. However, the other configuration and the manufacturing method thereof can be the same. Therefore, the sheet 24a with an interposer shown in FIGS. 8 and 9 and FIGS. 10 and 11 can be used.

  As shown in FIG. 14, in parallel with the feeding of the sheet 24a with an interposer, at least one surface of the release sheet 45 is subjected to a release treatment, and the adhesive is laminated on the surface 46 of which the release sheet 45 is subjected to the release treatment. The laminate 20 having the layer 40 is prepared and fed.

  After that, the punching device 60 corresponds to the arrangement of the IC chip 32 on the sheet-like base material 31 of the sheet 24a with an interposer, as shown in FIG. The through holes 47 and 42 are sequentially formed. In the present embodiment, the through holes 47 and 42 are formed by the punching device 60.

  Next, the interposer-attached sheet 24a and the laminated body 20 are stacked while the surface of the interposer-attached sheet 24a on the side where the IC chip 32 is disposed and the surface of the laminate 30 on the adhesive layer 40 side face each other. The IC chip 32 is superposed by the nip roller 64 so that the IC chip 32 is disposed in the through holes 42 and 47 of the body 20. The superposed sheet 24 a with interposer and the laminated body 20 are bonded and fixed to each other by the adhesive force of the adhesive layer 40.

  Through the steps so far, the sheet 24a with an interposer shown in FIG. 8 and FIG. 9 or FIG. 10 and FIG. 11, the release sheet 45 on which at least one surface has been subjected to the release process, and the release process of the release sheet 45 have been performed. The surface 46 and the surface of the interposer-attached sheet 24a on which the IC chip 32 protrudes (at least one of the side of the sheet-like substrate 31 on which the IC chip 32 protrudes and the connecting member conductor 36a formed on the surface) A release sheet material 16a with an interposer pressure-sensitive adhesive body in which through-holes 42 and 47 for receiving an IC chip 32 protruding from the release sheet 45 and the adhesive layer 40 are formed. can get. And according to the obtained interposer pressure sensitive adhesive release sheet material 16a, the protruding IC chip 32 is disposed in the through holes 47 and 42 provided in the release sheet 45 and the adhesive layer 40, so at least the release The protrusion amount of the IC chip 32 can be reduced by the total thickness of the sheet 45 and the adhesive layer 40. Therefore, when the release sheet material 16a with the interposer pressure-sensitive adhesive body is piled up or wound up, the load appearance can be stabilized and the load applied to the IC chip 32 can be remarkably reduced. Also, manufacturing information and the like can be accurately written on the surface of the sheet-like substrate 31.

  Thereafter, the notch forming device 68 forms the notch 50 that penetrates the adhesive layer 40 of the laminate 20 from the interposer-attached release sheet material 16a side of the interposer-attached release sheet material 16a to the release sheet 45. By this cut 50, the IC tag 10 that is the interposer 10a including the base member 30, the connection member 34a, and the IC chip 32 connected to the connection member 34a and supported on the stacked body 20 is sequentially manufactured.

  Next, the portion 25 other than the portion forming the interposer 10a of the sheet with interposer 24a is peeled off from the release sheet 45 together with the adhesive layer 40 facing the portion 25 and removed. Thereby, the release sheet 14a with an interposer adhesive body is obtained.

  According to the manufacturing method of the release sheet 14a with the interposer pressure-sensitive adhesive body and the release sheet material 16a with the interposer pressure-sensitive adhesive body, the release sheet with the interposer pressure-sensitive adhesive body using the laminate 20 including the release sheet 45 and the pressure-sensitive adhesive layer 40. 14a and the release sheet material 16a with an interposer pressure-sensitive adhesive body are manufactured, so that the pressure-sensitive adhesive layer 40 that is difficult to handle can be easily handled as a part of the laminate 20. Moreover, by providing the through holes in the laminate 20, the through holes 47 and 42 aligned with each other can be formed in the release sheet 45 and the adhesive layer 40 at a time. Furthermore, as the laminate 20, a double-sided tape or the like that is generally widely used and available at a low cost can be used. Therefore, the high quality interposer pressure sensitive adhesive release sheet 14a and the interposer pressure sensitive adhesive release sheet material 16a in which the protruding IC chip 32 is disposed in the through holes 47 and 42 provided in the release sheet 45 and the pressure sensitive adhesive layer 40 are provided. It can be manufactured inexpensively and efficiently.

  In addition, the release sheet 14 with an interposer adhesive body can also be obtained by cutting the release sheet material 16a with an interposer adhesive body into each IC chip 32.

<Wound of IC tag pressure-sensitive adhesive material and method for producing the same>
Next, the wound body 19 of the IC tag pressure-sensitive adhesive material and the manufacturing method thereof will be described. Moreover, after explaining these, the winding body 19a of the material for interposer adhesive bodies and its manufacturing method are also demonstrated.

  As described above, the IC tag pressure-sensitive adhesive body 12 can be obtained by peeling off the pressure-sensitive adhesive layer 40 together with the IC tag 10 from the IC tag release sheet 14, and the IC tag pressure-sensitive adhesive body 12 is directly applied to the object to be pasted. Can do. However, when a large number of IC tags 10 are pasted on the object to be pasted, it is very complicated to peel off each IC tag 10 from the release sheet 45 each time. The same applies to the interposer 10a.

  The wound body 19 of the IC tag pressure-sensitive adhesive material and the manufacturing method thereof, and the wound body 19a of the interposer pressure-sensitive adhesive material and the manufacturing method thereof have been invented based on such knowledge.

  Hereinafter, an embodiment of a wound body 19 of an IC tag pressure-sensitive adhesive material and a method for manufacturing the same will be described with reference mainly to FIGS.

  16 is a schematic view showing a method of manufacturing the wound body 19 of the IC tag pressure-sensitive adhesive material, and FIG. 17 is a cross section of the wound body 19 of the IC tag pressure-sensitive adhesive material along the line GG in FIG. FIG. 18 is a schematic view showing a modification of the method for manufacturing the wound body 19 of the IC tag pressure-sensitive adhesive material. The manufacturing method of the wound body 19 of the IC tag pressure-sensitive adhesive material mainly includes the method of manufacturing the IC tag pressure-sensitive adhesive release sheet material 16 described with reference to FIGS. , Removing the release sheet 45 to produce the IC tag pressure-sensitive adhesive material 18, and winding the IC tag pressure-sensitive adhesive material 18, but the others are substantially the same. In FIG. 16 thru | or FIG. 17, while attaching the same code | symbol to the manufacturing method of the peeling sheet material 16 with an IC tag adhesive body, the detailed description which overlaps is abbreviate | omitted.

  By the way, in FIG. 16 thru | or FIG. 18, the IC tag adhesive body which can obtain the IC tag adhesive body 12 provided with the IC tag 10 which has the antenna 34 which consists of a pair of substantially rod-shaped conductor shown in FIG. 1 and FIG. An example is shown in which a wound body 19 of material is manufactured. Therefore, in the manufacturing method of the IC tag pressure-sensitive adhesive material shown in FIGS. 16 to 18 and described below, the size of the conductor (antenna 34) is changed as appropriate, so that the size of the conductor is the same except for the size of the conductor. Naturally, the wound body 19a of the interposer pressure-sensitive adhesive material including the interposer 10a that can be configured can be manufactured by the same method.

  When manufacturing the wound body 19 of the IC tag pressure-sensitive adhesive material, first, a plurality of antennas 34 are formed on the sheet-like base material 31 extending in a strip shape and provided on the sheet-like base material 31 and cut or left as it is. An IC tag-attached sheet 24 having an antenna conductor 36 and a plurality of IC chips 32 protruding from the sheet-like base material 31 electrically connected to the antenna conductor 36 on the sheet-like base material 31 is prepared. To do. Next, using the peeling processing device 78, the surface 25 on the side where the antenna conductor 36 of the IC tag-attached sheet 24 is not provided is peeled. The peeling process by the peeling processing device 78 is performed by applying silicon particles to the IC tag-attached sheet 24 or the like. In this way, the IC-tagged sheet 24 on which only one surface has been peeled off is fed.

  In FIG. 16 and FIG. 18 described later, a method of manufacturing the wound body 19 of the IC tag pressure-sensitive adhesive material using the IC tag-attached sheet 24 shown in FIGS. 10 and 11 is shown.

  As shown in FIG. 16, in parallel with the feeding of the IC-tagged sheet 24, the laminate 20 is prepared and fed. Thereafter, through-holes 47 and 42 corresponding to the arrangement of the IC chips 32 on the sheet-like base material 31 of the IC tag-attached sheet 24 are formed on the peeled sheet 45 and the adhesive layer 40 of the laminated body 20 fed by the punching device 60. , Will be formed sequentially.

  Next, the sheet 24 with IC tag and the laminated body 20 that are fed in face the surface of the IC tag sheet 24 on which the IC chip 32 is disposed and the surface of the laminated body 30 on the adhesive layer 40 side. At the same time, the IC chip 32 is superposed by the nip roller 64 so that the IC chip 32 is disposed in the through holes 42 and 47 of the laminate 20. The stacked IC tag-attached sheet 24 and the laminated body 20 are bonded and fixed to each other by the adhesive force of the adhesive layer 40. By the steps up to here, the release sheet material 16 with IC tag pressure-sensitive adhesive body is obtained.

  Thereafter, the release sheet 45 is peeled off (released) from the release sheet material 16 with IC tag pressure-sensitive adhesive body, whereby the IC tag pressure-sensitive adhesive material 18 is manufactured. Such an IC tag pressure-sensitive adhesive material 18 is provided on a sheet-like base material 31 that is peeled only on one surface 25 and extends in a strip shape, and on the surface on which the sheet-like base material 31 is not peeled. The antenna conductor 36 that is cut or formed as it is to form the plurality of antennas 34 and the surface that is electrically connected to the antenna conductor 36 and is not subjected to the peeling treatment of the sheet-like substrate 31. A plurality of protruding IC chips 32 and at least one of the surface of the antenna substrate 36 formed on the surface on which the sheet-like base material 31 is not peeled and on the surface (sheet 24 with an IC tag) The adhesive layer 40 is provided on the surface on which the IC chip 32 protrudes, in other words, on the surface on which the IC tag sheet 24 is not peeled (FIG. 17). . Further, the protruding IC chip 32 is disposed in a through hole 42 formed in the adhesive layer 40. By the way, as shown in FIGS. 16 and 17, the thickness of the IC chip 32 is preferably equal to or less than the thickness of the adhesive layer 40, and in this case, the IC chip 32 is completely in the through hole 42 of the adhesive layer 40. To become housed.

  In addition, as shown in FIG. 18, you may make it perform the process of peeling this peeling sheet 45 before the process of laminating the laminated body 20 and the sheet | seat 24 with an IC tag by the nip roller 64 mentioned above. That is, the release sheet 45 of the laminate 20 is peeled from the adhesive layer 40 to separate the release sheet 45 and the adhesive layer 40, and then the IC chip is placed in the through hole 42 of the adhesive layer 40 separated from the release sheet 45. The IC tag pressure-sensitive adhesive material 18 may be manufactured by superposing the IC tag-attached sheet 24 and the pressure-sensitive adhesive layer 40 in such a manner that 32 is disposed. By the way, in this case, it is preferable that the surface of the nip roller 64 in contact with the adhesive layer 40 is subjected to a peeling treatment.

  Next, the obtained IC tag pressure-sensitive adhesive material 18 is rotated so that the pressure-sensitive adhesive layer 40 faces the surface 25 on the side where the sheet-like base material 31 is peeled off. Is wound up by. In this way, the wound body 19 of the IC tag pressure-sensitive adhesive material is manufactured.

  According to such a method for manufacturing the wound body 19 of the IC tag pressure-sensitive adhesive material, the IC tag pressure-sensitive adhesive material 18 is manufactured using the laminate 20 having the release sheet 45 and the pressure-sensitive adhesive layer 40. Further, as the laminate 20, a double-sided tape or the like that is generally widely used and available at a low cost can be used. Therefore, the through-hole 42 can be easily formed in the pressure-sensitive adhesive layer 40 that is difficult to handle, and the IC tag pressure-sensitive adhesive material 18 can be manufactured at low cost.

  Further, according to the wound body 19 of the obtained IC tag pressure-sensitive adhesive material, since the protruding IC chip 32 is accommodated in the through hole 42 provided in the pressure-sensitive adhesive layer 40, at least the thickness of the pressure-sensitive adhesive layer 40. Only the protrusion amount of the IC chip 32 can be reduced. Therefore, the load form of the wound body 19 can be stabilized and the load applied to the IC chip 32 can be significantly reduced. Further, the exposed adhesive layer 40 of the IC tag adhesive material 18 faces the surface of the IC tag-attached sheet 24 that has been peeled off in the wound body 19. Therefore, according to this wound body 19, it can prevent that a suspended | floating matter etc. adhere to the adhesion layer 40, or the adhesion layer 40 contacts the exterior, Thereby, the adhesive force of the adhesion layer 40 falls. Can be prevented. From this point, it can be said that the wound body 19 of the IC tag pressure-sensitive adhesive material is suitable for transporting and storing the IC tag pressure-sensitive adhesive material 18.

  Further, the IC tag pressure-sensitive adhesive material 18 is unwound from the wound body 19 of the IC tag pressure-sensitive adhesive material, and the IC tag pressure-sensitive adhesive can be directly attached to the object to be pasted by simply cutting the material for each IC chip 32. The body 12 can be obtained. According to the IC tag pressure-sensitive adhesive body 12, since the protruding IC chip 32 is disposed in the through hole 42 provided in the pressure-sensitive adhesive layer 40, the protrusion amount of the IC chip 32 is at least the thickness of the pressure-sensitive adhesive layer 40. Can be reduced. Thereby, the IC tag 10 can be more firmly and stably attached to the object to be attached. In addition, in a state where the IC tag 10 is attached to the object to be attached, manufacturing information and the like can be accurately written on the surface of the base material 30.

  In addition, the wound body 19 of the IC tag pressure-sensitive adhesive material used for the IC tag pressure-sensitive adhesive body 12 shown in FIGS. 3 to 5 and FIGS. 6 and 7 can be manufactured by the manufacturing method described above.

  However, when the wound body 19 of the IC tag pressure-sensitive adhesive material for the IC tag pressure-sensitive adhesive body 12 shown in FIGS. 3 to 5 is manufactured, as shown in FIG. The coil-shaped part which makes a coil shape, and the conductor 37 for bridge | bridging which short-circuits the innermost periphery and outermost periphery of a coil-shaped part come to be included. Further, the punching device 60 attaches the bridge 35 (bridge conductor 37) to the laminate 20 corresponding to the arrangement of the bridge 35 (bridge conductor 37) on the sheet-like base material 31 of the sheet 24 with IC tag. Further, through holes 42 and 47 which can be disposed inside are further formed.

  On the other hand, when manufacturing the wound body 19 of the IC tag pressure-sensitive adhesive material for the IC tag pressure-sensitive adhesive body 12 shown in FIGS. 6 and 7, the IC chip 32 is provided on the antenna conductor 36 as shown in FIG. A sheet 24 with an IC tag on which the interposer 10a is arranged is prepared. Further, the punching device 60 causes the interposer 10a including the connecting member 34a (connecting member conductor 36a) in the laminated body 20 to correspond to the arrangement of the interposer 10a on the sheet-like base material 31 of the sheet 24 with the IC tag. Through-holes 42 and 47 are formed which can be arranged on the surface.

  In such a modification, the protrusions of the interposer 10a and the bridge 35 in the IC tag 10 can also be reduced by the through holes 47 and 42. Therefore, in the wound body 19 in which the IC tag adhesive material 18 is wound, the package can be stabilized, and the load applied to the IC chip 32, the interposer 10a including the IC chip 32, and the bridge 35 can be remarkably increased. It can be reduced. In addition, manufacturing information and the like can be accurately written on the surface of the base material 30 (the surface of the sheet-like base material 31). Further, when the IC tag 10 is attached to the object to be attached via the adhesive layer 40, not only the IC chip 32 but also the interposer 10 a and the bridge 35 protruding from the base material 30 are provided in the through hole 42 provided in the adhesive layer 40. Therefore, the amount of protrusion can be reduced by at least the thickness of the adhesive layer 40, whereby the IC tag 10 can be more firmly and stably attached to the object to be attached.

<Interposer Adhesive Material Roll and its Manufacturing Method>
Further, as described above, except for the difference in the size of the conductor based on the difference in the use of the conductor connected to the IC chip 32, it is the same as the IC tag 10 having a pair of substantially rod-shaped antennas 34. Such a configuration can be adopted for the interposer 10a. Therefore, as mentioned in the description of the manufacturing method of the wound body 19 of the IC tag pressure-sensitive adhesive material, the winding of the interposer pressure-sensitive adhesive material shown in FIGS. 15 to 17 is performed by the manufacturing method shown in FIGS. The body 19a can be manufactured.

  Hereinafter, the wound body 19a of the interposer pressure-sensitive adhesive material and the manufacturing method thereof will be described mainly with reference to FIGS. The same parts as those of the above-described wound body 19 of the IC tag pressure-sensitive adhesive material and the manufacturing method thereof are denoted by the same reference numerals, and detailed description thereof is omitted.

  When manufacturing the wound body 19a of the interposer pressure-sensitive adhesive material, first, a plurality of connection members 34a are formed on the sheet-like base material 31 extending in a strip shape and provided on the sheet-like base material 31, being cut or left as it is. A sheet 24a with an interposer having an antenna conductor 36 and a plurality of IC chips 32 that are electrically connected to the connection electrode conductor 36a on the sheet-like base material 31 and protrude from the sheet-like base material 31 is prepared. . Next, using the peeling processing device 78, the surface 25 on the side where the connection electrode conductor 36a of the IC tag-attached sheet 24 is not provided is peeled. In this way, the sheet 24a with an interposer having only one surface subjected to the peeling process is fed.

  As shown in FIG. 16, in parallel with the feeding of the sheet 24 a with interposer, the laminated body 20 is prepared and fed, and then the interposer is fed to the release sheet 45 and the adhesive layer 40 of the fed laminated body 20. Through holes 47 and 42 are sequentially formed by the punching device 60 corresponding to the arrangement of the IC chips 32 on the sheet-like base material 31 of the attached sheet 24a.

  Next, the interposer-attached sheet 24a and the laminated body 20 are stacked while the surface of the interposer-attached sheet 24a on the side where the IC chip 32 is disposed and the surface of the laminate 30 on the adhesive layer 40 side face each other. The IC chip 32 is superposed by the nip roller 64 so that the IC chip 32 is disposed in the through holes 42 and 47 of the body 20. The superposed sheet 24 a with interposer and the laminated body 20 are bonded and fixed to each other by the adhesive force of the adhesive layer 40. By the steps so far, the release sheet material 16a with an interposer pressure-sensitive adhesive body is obtained.

  Thereafter, the release sheet 45 is peeled off (released) from the release sheet material 16a with an interposer pressure-sensitive adhesive body to produce an interposer pressure-sensitive adhesive material 18a. Such an IC tag pressure-sensitive adhesive material 18a is provided on a sheet-like base material 31 that is stripped only on one surface 25 and extends in a strip shape, and on the surface on which the sheet-like base material 31 is not peeled. The connection member conductor 36a that is cut or formed as it is to form the plurality of connection members 34a, and the side that is electrically connected to the connection member conductor 36a and is not subjected to the peeling treatment of the sheet-like substrate 31 A plurality of IC chips 32 protruding from the surface of the sheet, and at least one of the surface of the sheet-like base material 31 on which the peeling treatment is not performed and the conductor 36a for the connecting member formed on the surface (interposer) Adhesive layer 4 provided on the surface of the attached sheet 24a on which the IC chip 32 protrudes, in other words, on the surface of the interposer-attached sheet 24a that has not been subjected to the peeling treatment. And a and (Figure 17). Further, the protruding IC chip 32 is disposed in a through hole 42 formed in the adhesive layer 40.

  As shown in FIG. 18, the step of removing the release sheet 45 may be performed before the step of superimposing the laminate 20 and the interposer-attached sheet 24 a by the nip roller 64 described above. That is, first, the release sheet 45 of the laminate 20 is peeled from the adhesive layer 40 to separate the release sheet 45 and the adhesive layer 40, and then inside the through-hole 42 of the adhesive layer 40 separated from the release sheet 45. The interposer pressure-sensitive adhesive body material 18a may be produced by stacking the interposer-attached sheet 24a and the adhesive layer 40 so that the IC chip 32 is disposed on the substrate. By the way, in this case, it is preferable that the surface of the nip roller 64 in contact with the adhesive layer 40 is subjected to a peeling treatment.

  Next, the obtained interposer pressure-sensitive adhesive material 18a is wound up by the winding core 80 so that the pressure-sensitive adhesive layer 40 faces the surface 25 on which the sheet-like base material 31 is peeled, A roll 19a of the interposer adhesive material is manufactured.

  According to such a method for manufacturing the wound body 19a of the interposer pressure-sensitive adhesive material, the IC tag pressure-sensitive adhesive material 18 is manufactured using the laminate 20 having the release sheet 45 and the pressure-sensitive adhesive layer 40. Further, as the laminate 20, a double-sided tape or the like that is generally widely used and available at a low cost can be used. Therefore, the through-hole 42 can be easily formed in the adhesive layer 40 that is difficult to handle, and the interposer adhesive material 18a can be manufactured at low cost.

  Further, according to the obtained wound body 19a of the interposer pressure-sensitive adhesive material, the protruding IC chip 32 is accommodated in the through hole 42 provided in the pressure-sensitive adhesive layer 40. Therefore, at least as much as the thickness of the pressure-sensitive adhesive layer 40. The amount of protrusion of the IC chip 32 can be reduced. Therefore, the load form of the wound body 19 can be stabilized and the load applied to the IC chip 32 can be significantly reduced. Further, the exposed adhesive layer 40 of the interposer adhesive material 18a faces the surface of the sheet 24a with an interposer that has been subjected to the peeling treatment in the wound body 19a. Therefore, according to this wound body 19a, it is possible to prevent floating matter or the like from adhering to the adhesive layer 40 or the adhesive layer 40 from coming into contact with the outside, thereby reducing the adhesive force of the adhesive layer 40. Can be prevented. From this point, it can be said that such a wound body 19a of the interposer pressure-sensitive adhesive material is suitable for transporting and storing the interposer pressure-sensitive adhesive material 18a.

  In addition, the interposer pressure-sensitive adhesive material 18a is unwound from the wound body 19a of the interposer pressure-sensitive adhesive material, and the interposer pressure-sensitive adhesive body 12a that can be attached to the antenna 34 as it is by simply cutting the material for each IC chip 32. Obtainable. According to the interposer pressure-sensitive adhesive body 12a, the protruding IC chip 32 is disposed in the through hole 42 provided in the pressure-sensitive adhesive layer 40. Therefore, the protrusion amount of the IC chip 32 is at least the thickness of the pressure-sensitive adhesive layer 40. Can be reduced. Thereby, the interposer 10a can be stuck on the antenna 34 more firmly and stably. In addition, in a state where the interposer 10a is attached to the antenna 34, manufacturing information and the like can be accurately written on the surface of the base material 30 (the surface of the sheet-like base material 31).
