Summary of the Invention

Problems to be Solved by the Invention

[0004] There is a demand for improving the handleability when conveying or the like an aggregate sheet as described in Patent Document 1.

[0005] The present invention provides an aggregate sheet support capable of improving the handleability of an aggregate sheet, and a method for producing an aggregate sheet using the aggregate sheet support.

Means for Solving the Problems

[0006] The present invention [1] includes an aggregate sheet support comprising a support member capable of supporting an aggregate sheet that includes a printed circuit board and a frame supporting the printed circuit board and having a through hole, wherein the support member has a base portion extending in the planar direction of the aggregate sheet in a state where the aggregate sheet is supported by the support member and having a thickness in the thickness direction of the aggregate sheet, and a shaft portion disposed on one side of the base portion in the thickness direction of the base portion and inserted through the through hole of the aggregate sheet in a state where the aggregate sheet is supported by the support member.

[0007] With this configuration, the aggregate sheet can be supported by the aggregate sheet support device with a simple setup in which the shaft portion of the support member is inserted through the through-hole of the aggregate sheet.

[0008] Furthermore, by handling the aggregate sheet while it is supported by the aggregate sheet support, the handling of the aggregate sheet can be improved.

[0009] The present invention [2] includes the assembly sheet support of [1], wherein the support member is arranged on one side of the base portion in the thickness direction, and the assembly sheet is further provided with a spacer portion that is arranged between the frame of the assembly sheet and the base portion while the assembly sheet is supported by the support member.

[0010] With this configuration, the spacer portion allows the assembled sheet to be supported by the support member while being separated from the base portion.

[0011] The present invention [3] includes the assembly sheet support of [2], wherein the spacer portion is arranged around the shaft portion.

[0012] With this configuration, the portion supported by the shaft and the portion in contact with the spacer can be concentrated in the aggregate sheet.

[0013] Therefore, the contact area between the aggregate sheet and the support member can be reduced, thereby suppressing deformation of the aggregate sheet due to contact with the support member.

[0014] The present invention [4] further comprises a second support member that is stackable on one side of the support member and capable of supporting the aggregate sheet, wherein the second support member has a second base portion having thickness in the thickness direction, a second shaft portion disposed on one side of the second base portion in the thickness direction and inserted through the through hole of the aggregate sheet when the aggregate sheet is supported by the second support member, and a hole disposed on the other side of the base portion in the thickness direction, and when the support member and the second support member are stacked, the shaft portion of the support member is inserted into the hole of the second support member, wherein the aggregate sheet support is any one of the aggregate sheet support devices described in [1] to [3] above.

[0015] With this configuration, multiple support members (support member and second support member) can be connected while each of them supports the aggregate sheet.

[0016] As a result, multiple aggregate sheets can be easily handled.

[0017] The present invention [5] includes the assembly sheet support described in [4], wherein the second support member is positioned on the other side of the second base portion in the thickness direction, the assembly sheet is supported by the support member, and the support member and the second support member are stacked, and the assembly sheet support further includes a second spacer portion positioned between the frame of the assembly sheet and the second base portion.

[0018] With this configuration, the second spacer portion allows the assembled sheet to be supported by the support member while being separated from the second base portion.

[0019] The present invention [6] includes the assembly sheet support of [5] above, wherein the second spacer portion has the hole.

[0020] With this configuration, the portion supported by the shaft and the portion in contact with the second spacer can be concentrated in the aggregate sheet.

[0021] Accordingly, the contact area between the assembly sheet and the second support member can be reduced, and deformation of the assembly sheet due to contact with the second support member can be suppressed.

[0022] The present invention [7] includes the assembly sheet support according to any one of the above [4] to [6], wherein the assembly sheet support further comprises a rod for suspending the support member and the second support member, a first member supporting one end of the rod, and a second member supporting the other end of the rod.

[0023] According to such a configuration, the plurality of support members (the support member and the second support member) can be collectively handled with the rod.

[0024] The present invention [8] includes the assembly sheet support according to the above [7], wherein the support member further has an engaging portion that engages with the rod, and the second support member further has a second engaging portion that engages with the rod.

[0025] The present invention [9] includes the assembly sheet support according to any one of the above [1] to [3], wherein the assembly sheet support further comprises a rod for suspending the support member, a first member supporting one end of the rod, and a second member supporting the other end of the rod.

[0026] The present invention

[10] includes the assembly sheet support according to the above [9], wherein the support member further has an engaging portion that engages with the rod.

[0027] The present invention

[11] is a method for producing the assembly sheet using the assembly sheet support according to any one of the above [1] to

[10] , the method comprising: a pattern step of forming an insulating layer on one surface of the metal foil drawn out from a first roll that is a roll of the metal foil, forming a conductor pattern disposed on one surface of the insulating layer, and forming the through-holes in the metal foil to produce a second roll having the plurality of assembly sheets; and a cutting step of cutting each of the plurality of assembly sheets from the second roll, wherein the assembly sheet support supports the cut assembly sheet.

[0028] According to such a configuration, the cut aggregate sheet can be handled with the aggregate sheet support.

[0029] Therefore, the handleability of the cut aggregate sheet can be improved.

[0030] The present invention

[12] further includes the method for producing an aggregate sheet according to the above

[11] , which includes a plating step of plating the terminals of the conductor pattern in a state where the aggregate sheet is supported by the aggregate sheet support.

[0031] According to such a configuration, in the plating step, the handleability of the cut aggregate sheet can be improved. Effects of the Invention

[0035] 1. Collective Sheet First, let me explain aggregate sheets.

[0036] As shown in Figure 1, the assembled sheet 1 has a sheet shape that extends in a first direction and a second direction. The second direction is perpendicular to the first direction. The assembled sheet 1 comprises a plurality of wiring circuit boards 2 and a frame 3.

[0037] (1) Wiring circuit board Multiple wiring circuit boards 2 are arranged with spacing between them in a first direction and also with spacing between them in a second direction. Each of the multiple wiring circuit boards 2 has the same structure. Therefore, we will describe one of the multiple wiring circuit boards 2 and omit the descriptions of the other wiring circuit boards 2.

[0038] The wiring circuit board 2 extends in a first direction and a second direction. In this embodiment, the wiring circuit board 2 has a substantially rectangular shape. However, the shape of the wiring circuit board 2 is not limited.

[0039] As shown in Figures 2A and 2B, the wiring circuit board 2 has a support layer 21, a base insulating layer 22 as an example of an insulating layer, a conductor pattern 23, and a cover insulating layer 24.

[0040] (1-1) Support layer The support layer 21 supports the base insulating layer 22, the conductor pattern 23, and the cover insulating layer 24 (see Figure 2B). In this embodiment, the support layer 21 is made of metal foil. Examples of metals include stainless steel alloy and copper alloy.

[0041] The thickness of the metal foil, i.e., the thickness of the support layer 21, is, for example, 200 μm or less, preferably 150 μm or less, more preferably 50 μm or less, and more preferably 30 μm or less, and for example, 10 μm or more, preferably 15 μm or more.

[0042] (1-2) Base insulating layer The base insulating layer 22 is positioned on one surface S1 of the support layer 21 in the thickness direction. The thickness direction is perpendicular to the first and second directions. The base insulating layer 22 is positioned between the support layer 21 and the conductor pattern 23 in the thickness direction. The base insulating layer 22 insulates the support layer 21 from the conductor pattern 23. The base insulating layer 22 is made of resin. An example of the resin is polyimide.

[0043] The thickness of the base insulating layer 22 is, for example, 30 μm or less, preferably 15 μm or less, and for example, 1 μm or more, preferably 3 μm or more.

[0044] (1-3) Conductor Pattern The conductor pattern 23 is arranged on one side S11 of the base insulating layer 22 in the thickness direction. In the thickness direction, the conductor pattern 23 is arranged on the side opposite the support layer 21 to the base insulating layer 22. The shape of the conductor pattern 23 is not limited.

[0045] In this embodiment, as shown in Figure 1, the conductor pattern 23 has multiple terminals 231A, 231B, 231C, 231D, multiple terminals 232A, 232B, 232C, 232D, and multiple wires 233A, 233B, 233C, 233D. The number of terminals and wires is not limited.

[0046] (1-3-1) terminal Terminals 231A, 231B, 231C, and 231D are arranged at one end of the wiring circuit board 2 in the second direction. In this embodiment, terminals 231A, 231B, 231C, and 231D are spaced apart from each other and arranged in the first direction. Each of terminals 231A, 231B, 231C, and 231D has a corner land shape.

[0047] As shown in Figure 2A, terminal 231A has a conductor layer 2311 and a plating layer 2312.

[0048] The conductor layer 2311 is the main body portion of the terminal 231A. The conductor layer 2311 is arranged on one side S11 of the base insulating layer 22 in the thickness direction. The conductor layer 2311 is made of metal. For example, copper can be used as the metal.

[0049] The thickness of the conductive layer 2311 is, for example, 3 μm or more, preferably 5 μm or more, and for example, 50 μm or less, preferably 30 μm or less.

[0050] The plating layer 2312 covers the surface of the conductor layer 2311. The plating layer 2312 suppresses corrosion of the conductor layer 2311. The plating layer 2312 is made of a metal. For example, gold can be used as the metal.

[0051] The thickness of the plating layer 2312 is, for example, 0.1 μm or more, preferably 0.2 μm or more, and for example, 5 μm or less, preferably 4 μm or less.

[0052] Terminals 231B, 231C, and 231D have the same structure as terminal 231A. Therefore, the explanation of terminals 231B, 231C, and 231D is omitted.

[0053] As shown in Figure 1, terminals 232A, 232B, 232C, and 232D are located at the other end of the wiring circuit board 2 in the second direction. In this embodiment, terminals 232A, 232B, 232C, and 232D are spaced apart from each other and arranged in the first direction. Each of terminals 232A, 232B, 232C, and 232D has a corner land shape.

[0054] Terminals 232A, 232B, 232C, and 232D have the same structure as terminal 231A. Therefore, the explanation of terminals 232A, 232B, 232C, and 232D is omitted.

[0055] (1-3-2) Wiring One end of wire 233A is connected to terminal 231A. The other end of wire 233A is connected to terminal 232A. Wire 233A electrically connects terminals 231A and 232A.

[0056] One end of wire 233B is connected to terminal 231B. The other end of wire 233B is connected to terminal 232B. Wire 233B electrically connects terminals 231B and 232B.

[0057] One end of wire 233C is connected to terminal 231C. The other end of wire 233C is connected to terminal 232C. Wire 233C electrically connects terminals 231C and 232C.

[0058] One end of wire 233D is connected to terminal 231D. The other end of wire 233D is connected to terminal 232D. Wire 233D electrically connects terminals 231D and 232D.

[0059] In the following explanation, terminals 231A, 231B, 231C, and 231D will each be referred to as terminal 231, terminals 232A, 232B, 232C, and 232D will each be referred to as terminal 232, and wiring 233A, 233B, 233C, and 233D will each be referred to as wiring 233.

[0060] As shown in Figure 2B, the wiring 233 is made of the same metal as the conductor layer 2311 of the terminal 231 (see Figure 2A). The thickness of the wiring 233 is, for example, 3 μm or more, preferably 5 μm or more, and for example, 50 μm or less, preferably 30 μm or less.

[0061] (1-4) Cover insulating layer As shown in Figure 1, the cover insulating layer 24 covers all the wiring 233. The cover insulating layer 24 is positioned on top of the base insulating layer 22 in the thickness direction. Note that the cover insulating layer 24 does not cover terminals 231 and 232. The cover insulating layer 24 is made of resin. For example, polyimide can be used as the resin.

[0062] The thickness of the cover insulating layer 24 is, for example, 30 μm or less, preferably 15 μm or less, and for example, 1 μm or more, preferably 3 μm or more.

[0063] (2) Frame Frame 3 is positioned around the outer periphery of the assembly sheet 1. Frame 3 surrounds multiple wiring circuit boards 2. In this embodiment, frame 3 has a frame shape. Specifically, frame 3 has a first frame 3A, a second frame 3B, a third frame 3C, and a fourth frame 3D.

[0064] The first frame 3A is positioned at one end of the aggregate sheet 1 in the first direction. The first frame 3A extends in the second direction.

[0065] The second frame 3B is positioned at the other end of the assembly sheet 1 in the first direction. The second frame 3B is positioned away from the first frame 3A in the first direction. Multiple wiring circuit boards 2 are positioned between the first frame 3A and the second frame 3B in the first direction. The second frame 3B extends in the second direction.

[0066] The third frame 3C is positioned at one end of the aggregate sheet 1 in the second direction. The third frame 3C extends in the first direction. One end of the third frame 3C in the first direction connects to one end of the first frame 3A in the second direction at corner C1 of the aggregate sheet 1. The other end of the third frame 3C in the first direction connects to one end of the second frame 3B in the second direction at corner C2 of the aggregate sheet 1.

[0067] The fourth frame 3D is positioned at the other end of the assembly sheet 1 in the second direction. The fourth frame 3D is positioned away from the third frame 3C in the second direction. Multiple wiring circuit boards 2 are positioned between the third frame 3C and the fourth frame 3D in the second direction. The fourth frame 3D extends in the first direction. One end of the fourth frame 3D in the first direction connects to the other end of the first frame 3A in the second direction at corner C3 of the assembly sheet 1. The other end of the fourth frame 3D in the first direction connects to the other end of the second frame 3B in the second direction at corner C4 of the assembly sheet 1.

[0068] As shown in Figure 2A, the frame 3 is made of metal foil. The frame 3 is made of the same metal foil as the support layer 21 of the wiring circuit board 2. Examples of metals include stainless steel alloy and copper alloy. The thickness of the metal foil, i.e., the thickness T11 of the frame 3, is, for example, 200 μm or less, preferably 150 μm or less, more preferably 50 μm or less, and more preferably 30 μm or less, and for example, 10 μm or more, preferably 15 μm or more.

[0069] If the rigidity of frame 3 is low, wrinkles may form in the assembled sheet 1 when handling it. This makes handling the assembled sheet 1 difficult. In particular, if the thickness T11 of frame 3 is thin, the rigidity of frame 3 tends to be insufficient. Specifically, if the thickness T11 of frame 3 is 50 μm or less, the rigidity of frame 3 tends to be insufficient.

[0070] Situations in which the aggregate sheet 1 is difficult to handle include, for example, transporting the aggregate sheet 1 and the plating process in the manufacturing method of the aggregate sheet 1, which will be described later.

[0071] Furthermore, in this embodiment, the assembled sheet 1 has notches 5 between the frame 3 and the wiring circuit board 2, and between the two wiring circuit boards 2. As a result, the overall rigidity of the assembled sheet 1 is even lower. Consequently, handling the assembled sheet 1 is more difficult.

[0072] The assembled sheet 1 has a connection part 6A (see Figure 1) that connects the frame 3 to the wiring circuit board 2, and a connection part 6B (see Figure 1) that connects two wiring circuit boards 2 to each other. Multiple wiring circuit boards 2 are connected to each other via the connection part 6B and supported by the frame 3 via the connection part 6A.

[0073] As shown in Figure 1, the frame 3 has multiple through holes 31A, 31B, 31C, and 31D.

[0074] In this embodiment, through-hole 31A is located at corner C1. Through-hole 31B is located at corner C2. Through-hole 31C is located at corner C3. Through-hole 31D is located at corner C4. In this embodiment, each of the through-holes 31A, 31B, 31C, and 31D has a circular shape.

[0075] In the following description, through holes 31A, 31B, 31C, and 31D will each be referred to as through hole 31. The number, arrangement, and shape of the through holes 31 are not limited.

[0076] 2. Support for aggregated sheet Next, we will describe the sheet assembly support 10 for supporting the sheet assembly 1.

[0077] As shown in Figure 3, the sheet assembly support 10 comprises a plurality of support members 11 (11A, 11B, 11C, 11D, 11E), a plurality of rods 12 (12A, 12B, 12C, 12D), a first member 13, and a second member 14. Rods 12B and 12D are not shown.

[0078] (1) Support member Multiple support members 11A, 11B, 11C, 11D, and 11E are each capable of supporting the aggregate sheet 1. In this embodiment, support member 11A supports aggregate sheet 1A, support member 11B supports aggregate sheet 1B, support member 11C supports aggregate sheet 1C, and support member 11D supports aggregate sheet 1D. In this embodiment, support member 11E does not support aggregate sheet 1. The number of support members 11 is not limited.

[0079] As shown in Figure 4, the support member 11A has a base portion 111, a plurality of shaft portions 112 (112A, 112B, 112C, 112D), a plurality of first spacer portions 113 (113A, 113B, 113C, 113D) as an example of a spacer portion, a plurality of second spacer portions 114 (114A, 114B, 114C, 114B), and a plurality of engaging portions 115 (115A, 115B, 115C, 115D).

[0080] (1-1) Base part As shown in Figures 3 and 4, with the aggregate sheet 1A supported by the support member 11A, the base portion 111 extends in the planar direction (first direction and second direction) of the aggregate sheet 1A. With the aggregate sheet 1A supported by the support member 11A, the base portion 111 has thickness in the thickness direction of the aggregate sheet 1A.

[0081] In this embodiment, the base portion 111 has a rectangular frame shape. The shape of the base portion 111 is not limited. The base portion 111 may also be flat.

[0082] The base portion 111 is made of, for example, a resin. Examples of resins include polyethylene terephthalate, polyethylene, polypropylene, polyetheretherketone, and polycarbonate.

[0083] (1-2) Shaft As shown in Figures 4 and 5, each of the multiple shaft portions 112 is positioned on one side of the base portion 111 in the thickness direction of the base portion 111. With the aggregate sheet 1A supported by the support member 11A, shaft portion 112A is inserted through the through hole 31A (see Figure 1) of the aggregate sheet 1A, shaft portion 112B is inserted through the through hole 31B (see Figure 1) of the aggregate sheet 1A, shaft portion 112C is inserted through the through hole 31C (see Figure 1) of the aggregate sheet 1A, and shaft portion 112D is inserted through the through hole 31D (see Figure 1) of the aggregate sheet 1A. In other words, the support member 11A supports the aggregate sheet 1A by having the shaft portion 112A inserted through the through hole 31A of the aggregate sheet 1A, the shaft portion 112B inserted through the through hole 31B of the aggregate sheet 1A, the shaft portion 112C inserted through the through hole 31C of the aggregate sheet 1A, and the shaft portion 112D inserted through the through hole 31D of the aggregate sheet 1A.

[0084] The shaft portion 112A extends in the thickness direction. The shaft portion 112A has a cylindrical shape. However, the shape of the shaft portion 112A is not limited. The shape of the shaft portion 112A may be a rectangular prism. The shaft portions 112B, 112C, and 112D have the same structure as the shaft portion 112A. Therefore, the description of the shaft portions 112B, 112C, and 112D is omitted.

[0085] (1-3) First spacer section Each of the multiple first spacer portions 113 is positioned on one side of the base portion 111 in the thickness direction. The first spacer portion 113A is positioned around the shaft portion 112A. The first spacer portion 113B is positioned around the shaft portion 112B. The first spacer portion 113C is positioned around the shaft portion 112C. The first spacer portion 113D is positioned around the shaft portion 112D.

[0086] As shown in Figure 3, the first spacer portion 113A is positioned in the thickness direction between the frame 3 (see Figure 1) and the base portion 111 of the aggregate sheet 1A, while the aggregate sheet 1A is supported by the support member 11A.

[0087] As shown in Figure 5A, the first spacer portion 113A extends in the thickness direction. The first spacer portion 113A has a cylindrical shape. However, the shape of the first spacer portion 113A is not limited. The shape of the first spacer portion 113A may be a rectangular prism. The diameter of the first spacer portion 113A is larger than the diameter of the shaft portion 112A and also larger than the diameter of the through hole 31A.

[0088] In the thickness direction, the dimension L1 from one side of the base portion 111 to the tip of the first spacer portion 113A is shorter than the dimension L2 from one side of the base portion 111 to the tip of the shaft portion 112A.

[0089] The first spacer sections 113B, 113C, and 113D have the same structure as the first spacer section 113A. Therefore, the description of the first spacer sections 113B, 113C, and 113D is omitted.

[0090] (1-4) Second spacer section The second spacer portion 114A is positioned in the thickness direction on the opposite side of the base portion 111 from the first spacer portion 113A. The second spacer portion 114B (see Figure 4) is positioned in the thickness direction on the opposite side of the base portion 111 from the first spacer portion 113B. The second spacer portion 114C (see Figure 4) is positioned in the thickness direction on the opposite side of the base portion 111 from the first spacer portion 113C. The second spacer portion 114D (see Figure 4) is positioned in the thickness direction on the opposite side of the base portion 111 from the first spacer portion 113D. In other words, the multiple second spacer portions 114 are positioned on the other side of the base portion 111 in the thickness direction.

[0091] In this embodiment, the second spacer portion 114A, together with the shaft portion 112A and the first spacer portion 113A, constitutes a single member that penetrates the base portion 111. The second spacer portion 114B, together with the shaft portion 112B and the first spacer portion 113B, constitutes a single member that penetrates the base portion 111. The second spacer portion 114C, together with the shaft portion 112C and the first spacer portion 113C, constitutes a single member that penetrates the base portion 111. The second spacer portion 114D, together with the shaft portion 112D and the first spacer portion 113D, constitutes a single member that penetrates the base portion 111.

[0092] The second spacer portion 114A extends in the thickness direction. The second spacer portion 114A has a cylindrical shape. However, the shape of the second spacer portion 114A is not limited. The shape of the second spacer portion 114A may be a rectangular prism. The diameter of the second spacer portion 114A is larger than the diameter of the through hole 31A.

[0093] As shown in Figures 5A and 5B, the second spacer portion 114A has a hole 1141. In other words, the support member 11A has a hole 1141. The hole 1141 is located on the other side of the base portion 111 in the thickness direction. The hole 1141 is circular in shape. The shape of the hole 1141 is not limited. The hole 1141 may be rectangular.

[0094] (1-5) Engagement part The engaging portions 115A, 115B, 115C, and 115D are arranged on the outer circumference of the base portion 111. The engaging portions 115A, 115B, 115C, and 115D are spaced apart from each other. In this embodiment, each of the engaging portions 115A, 115B, 115C, and 115D is arranged one at each of the four corners of the base portion 111. Engaging portion 115A engages with rod 12A. Engaging portion 115B engages with rod 12B. Engaging portion 115C engages with rod 12C. Engaging portion 115D engages with rod 12D.

[0095] The engaging portion 115A has a circular shape. The shape of the engaging portion 115A is not limited. The shape of the engaging portion 115A may be rectangular. The engaging portion 115A has a through hole 1151. The through hole 1151 has a circular shape. The shape of the through hole 1151 is not limited. The shape of the through hole 1151 may be rectangular. The rod 12A is inserted through the through hole 1151 of the engaging portion 115A. As a result, the engaging portion 115A engages with the rod 12A. Note that the engaging portion 115A may have a notch instead of a through hole 1151, as long as it can engage with the rod 12A.

[0096] The engaging parts 115B, 115C, and 115D have the same structure as engaging part 115A. Therefore, the description of engaging parts 115B, 115C, and 115D is omitted.

[0097] (1-6) Stack structure of multiple support members Each of the support members 11B, 11C, 11D, and 11E has the same structure as support member 11A. That is, support member 11B (second support member), like support member 11A, has a base portion 111 (second base portion), a plurality of shaft portions 112A, 112B, 112C, 112D (second shaft portion), a plurality of first spacer portions 113A, 113B, 113C, 113D, a plurality of second spacer portions 114A, 114B, 114C, 114B, and a plurality of engaging portions 115A, 115B, 115C, 115D (second engaging portions).

[0098] Support members 11A, 11B, 11C, 11D, and 11E are stackable in the thickness direction. Specifically, support member 11B can be stacked on one side of support member 11A in the thickness direction. Support member 11C can be stacked on one side of support member 11B in the thickness direction. Support member 11D can be stacked on one side of support member 11C in the thickness direction. Support member 11E can be stacked on one side of support member 11D in the thickness direction.

[0099] With support member 11A and support member 11B stacked, the shaft portion 112A of support member 11A is inserted into the hole 1141 of the second spacer portion 114A of support member 11B, the shaft portion 112B of support member 11A is inserted into the hole 1141 of the second spacer portion 114B of support member 11B, the shaft portion 112C of support member 11A is inserted into the hole 1141 of the second spacer portion 114C of support member 11B, and the shaft portion 112D of support member 11A is inserted into the hole 1141 of the second spacer portion 114D of support member 11B.

[0100] This connects the support member 11A and the support member 11B.

[0101] Furthermore, with the aggregate sheet 1A supported by the support member 11A, and the support member 11A and the support member 11B stacked, the corner C1 (see Figure 1) of the aggregate sheet 1A supported by the support member 11A is positioned between the first spacer portion 113A of the support member 11A and the second spacer portion 114A of the support member 11B, the corner C2 (see Figure 1) is positioned between the first spacer portion 113B of the support member 11A and the second spacer portion 114B of the support member 11B, the corner C3 (see Figure 1) is positioned between the first spacer portion 113C of the support member 11A and the second spacer portion 114C of the support member 11B, and the corner C4 (see Figure 1) is positioned between the first spacer portion 113D of the support member 11A and the second spacer portion 114D of the support member 11B.

[0102] Furthermore, with the aggregate sheet 1A supported by the support member 11A, and the support member 11A and the support member 11B stacked together, the multiple second spacer portions 114A, 114B, 114C, and 114D are positioned between the frame 3 of the aggregate sheet 1A and the base portion 111 of the support member 11B.

[0103] As a result, the aggregate sheet 1A is positioned away from the base portion 111 of the support member 11A in the thickness direction.

[0104] (2) Rod Rods 12A, 12B, 12C, and 12D are components for suspending support members 11A, 11B, 11C, 11D, and 11E.

[0105] The rod 12A engages with the respective engaging portions 115A of the support members 11A, 11B, 11C, 11D, and 11E. In this embodiment, the rod 12A is inserted through the through holes 1151 of the respective engaging portions 115A of the support members 11A, 11B, 11C, 11D, and 11E.

[0106] The rod 12B engages with the respective engaging portions 115B of the support members 11A, 11B, 11C, 11D, and 11E. In this embodiment, the rod 12B is inserted through the through holes 1151 of the respective engaging portions 115B of the support members 11A, 11B, 11C, 11D, and 11E.

[0107] The rod 12C engages with the respective engaging portions 115C of the support members 11A, 11B, 11C, 11D, and 11E. In this embodiment, the rod 12C is inserted through the through holes 1151 of the respective engaging portions 115C of the support members 11A, 11B, 11C, 11D, and 11E.

[0108] The rod 12D engages with the respective engaging portions 115D of the support members 11A, 11B, 11C, 11D, and 11E. In this embodiment, the rod 12D is inserted through the through holes 1151 of the respective engaging portions 115D of the support members 11A, 11B, 11C, 11D, and 11E.

[0109] (3) First member As shown in Figure 3, the first member 13 is positioned in the thickness direction on one side of the stacked support members 11A, 11B, 11C, 11D, and 11E. The first member 13 supports one end of each of the rods 12A, 12B, 12C, and 12D.

[0110] More specifically, as shown in Figure 6, in this embodiment, the first member 13 has a rectangular frame shape. The first member 13 has a plurality of holes 131A, 131B, 131C, 131D and a handle 132.

[0111] One end of rod 12A is inserted through hole 131A. One end of rod 12B is inserted through hole 131B. One end of rod 12C is inserted through hole 131C. One end of rod 12D is inserted through hole 131D.

[0112] The handle 132 is positioned at one end of the first member 13 in the second direction. The handle 132 is grasped by an operator. The handle 132 may also be grasped by the arm of a work machine. The shape of the handle 132 is not limited. In this embodiment, the handle 132 has a substantially rectangular frame shape.

[0113] (4) Second member As shown in Figure 3, the second member 14 is positioned on the other side of the stacked support members 11A, 11B, 11C, 11D, and 11E in the thickness direction. The second member 14 is positioned on the opposite side of the first member 13 from the stacked support members 11A, 11B, 11C, 11D, and 11E in the thickness direction. The second member 14 supports the other ends of the rods 12A, 12B, 12C, and 12D. In this embodiment, the second member 14 has the same shape as the first member 13. Therefore, a description of the second member 14 is omitted. Note that the second member 14 may have a different shape from the first member 13.

[0114] 3. Method for manufacturing aggregate sheets Next, the manufacturing method for the aggregate sheet 1 described above will be explained.

[0115] In this embodiment, the aggregate sheet 1 is manufactured by an additive process. The manufacturing method of the aggregate sheet 1 includes a patterning step (see Figures 7A to 7C), a cutting step (see Figure 8A), and a plating step (see Figure 8B).

[0116] (1) Patterning process As shown in Figures 7A to 7C, in the patterning process, a base insulating layer 22 (see Figure 7A) and a conductor pattern 23 (see Figure 7B) are formed on one side S31 of the metal foil M drawn from a first roll R1 (not shown), which is a roll of metal foil, and through holes 31 (see Figure 7C) are formed in the metal foil M to manufacture a second roll R2 (see Figure 8A) having multiple aggregate sheets 1. During the patterning process, the metal foil M is stretched between the first roll R1 and the second roll R2.

[0117] In detail, to form the base insulating layer 22, first, a photosensitive resin solution (varnish) is applied to one side S31 of the metal foil M and dried to form a photosensitive resin coating. Next, the photosensitive resin coating is exposed to light and developed.

[0118] As a result, as shown in Figure 7A, the base insulating layer 22 is formed on one side S31 of the metal foil M.

[0119] The conductor pattern 23 is formed by electroplating.

[0120] To form the conductor pattern 23 by electroplating, a seed layer is first formed on one side S11 of the base insulating layer 22 and on one side S31 of the metal foil M. The seed layer is formed, for example, by sputtering. Examples of materials for the seed layer include chromium, copper, nickel, titanium, and alloys thereof.

[0121] Next, a plating resist is bonded to one side S11 of the base insulating layer 22 and to one side S31 of the metal foil M.

[0122] Next, the plating resist is exposed while the areas where the conductor layer 2311 (see Figure 2A) and wiring 233 (see Figure 2B) are to be formed are shielded from light.

[0123] Next, the exposed plating resist is developed. This removes the plating resist from the light-shielded areas, exposing the seed layer in the areas where the conductor layer 2311 and wiring 233 will be formed. The plating resist remains in the exposed areas, i.e., the areas where the conductor layer 2311 and wiring 233 will not be formed.

[0124] Next, a conductive layer 2311 and wiring 233 are formed on the exposed seed layer by electroplating. After the electroplating is complete, the plating resist is peeled off. Then, the seed layer that was covered by the plating resist is removed by etching.

[0125] As a result, as shown in Figure 3B, the conductor layer 2311 and the wiring 233 are formed on one side S11 of the base insulating layer 22.

[0126] Next, a cover insulating layer 24 (see Figures 1 and 2B) is formed on the base insulating layer 22 and the conductor pattern 23 in the same manner as the formation of the base insulating layer 22.

[0127] Next, as shown in Figure 7C, the metal foil M is etched to form through holes 31. In addition, notches 5 are formed between the frame 3 and the wiring circuit board 2, and between the two wiring circuit boards 2.

[0128] Based on the above, a second roll R2 having multiple aggregate sheets 1 is manufactured.

[0129] (2) Cutting process Next, after the patterning process, the cutting process is carried out.

[0130] As shown in Figure 8A, in the cutting process, each of the multiple aggregate sheets 1 is cut from the second roll R2. More specifically, the aggregate sheets 1 unwound from the second roll R2 are cut with a cutter. The cutting method is not limited. This results in multiple aggregate sheets 1 that are independent of each other.

[0131] (3) Plating process Next, after the cutting process, the plating process is carried out.

[0132] In the plating process, the conductor layers 2311 of all terminals 231 and all terminals 232 of the cut assembly sheet 1 are plated. In the plating process, the conductor layers 2311 are plated by electroless plating. As a result, a plating layer 2312 (see Figure 2A) is formed on the surface of the conductor layers 2311.

[0133] For more details, as shown in Figure 8B, the cut aggregate sheet 1 is attached to the aggregate sheet support 10, and the aggregate sheet support 10 is immersed in the plating solution.

[0134] This improves the handling of the cut aggregate sheet 1. Furthermore, when the aggregate sheet 1 is attached to the aggregate sheet support 10, the movement of the four corners C1, C2, C3, and C4 is restricted by the four shaft portions 112 (see Figure 4) of the support member 11. Therefore, it is possible to suppress the formation of wrinkles in the aggregate sheet 1 during the plating process.

[0135] 3. Effects (1) With the aggregate sheet support 10, as shown in Figure 3, the aggregate sheet 1 can be supported by the aggregate sheet support 10 with a simple configuration in which the shaft portion 112 (see Figure 4) of the support member 11 is inserted through the through hole 31 (see Figure 1) of the aggregate sheet 1.

[0136] Furthermore, by handling the aggregate sheet 1 while it is supported by the aggregate sheet support 10, the handling of the aggregate sheet 1 can be improved.

[0137] (2) According to the aggregate sheet support 10, as shown in Figures 3 and 5A, the support member 11 has a plurality of first spacer portions 113. As shown in Figure 3, the plurality of first spacer portions 113 are arranged between the frame 3 (see Figure 1) and the base portion 111 of the aggregate sheet 1 when the aggregate sheet 1 is supported by the support member 11.

[0138] Therefore, the multiple first spacer portions 113 allow the assembled sheet 1 to be supported on the support member 11 while being separated from the base portion 111.

[0139] This allows, for example, in the plating process, the plating solution to be reliably brought into contact with the other side of the aggregate sheet 1 in the thickness direction.

[0140] (3) According to the aggregate sheet support 10, as shown in Figure 4, the first spacer portion 113 is arranged around the shaft portion 112.

[0141] Therefore, in the aggregate sheet 1, the portion supported by the shaft portion 112 and the portion in contact with the first spacer portion 113 can be concentrated in one area.

[0142] Therefore, the contact area between the aggregate sheet 1 and the support member 11 can be reduced, thereby suppressing deformation of the aggregate sheet 1 due to contact with the support member 11.

[0143] (4) With the assembled sheet support 10, as shown in Figure 3, with the support member 11A and the support member 11B stacked together, the shaft portion 112 of the support member 11A (see Figure 5A) is inserted into the hole 1141 of the support member 11B (see Figure 5A).

[0144] This allows the support member 11A to support the aggregate sheet 1A and the support member 11B to support the aggregate sheet 1B, and the support member 11A and the support member 11B to be connected.

[0145] As a result, multiple aggregate sheets 1A and 1B can be easily handled.

[0146] (5) According to the aggregate sheet support 10, as shown in Figures 3 and 5A, the support member 11 has a plurality of second spacer portions 114. As shown in Figure 3, the plurality of second spacer portions 114 are arranged between the frame 3 of the aggregate sheet 1 (see Figure 1) and the base portion 111 of the support member 11B when the aggregate sheet 1A is supported by the support member 11A and the support member 11A and the support member 11B are stacked.

[0147] Therefore, the multiple second spacer portions 114 allow the assembled sheet 1 to be supported on the support member 11A while being separated from the base portion 111 of the support member 11B.

[0148] This allows, for example, in the plating process, the plating solution to be reliably brought into contact with one side of the aggregate sheet 1 in the thickness direction.

[0149] (6) According to the aggregate sheet support 10, as shown in Figure 5B, the second spacer portion 114 has a hole 1411.

[0150] Therefore, in the aggregate sheet 1A, the portion supported by the shaft portion 112 and the portion that contacts the second spacer portion 114 of the support member 11B can be concentrated in one area.

[0151] Therefore, the contact area between the aggregate sheet 1A and the support member 11B can be reduced, thereby suppressing deformation of the aggregate sheet 1A due to contact with the support member 11B.

[0152] (7) With the aggregate sheet support 10, as shown in Figure 3, multiple support members 11A, 11B, 11C, 11D, 11E can be handled together by the rods 12A, 12B, 12C, 12D.

[0153] (8) According to the manufacturing method of the aggregate sheet 1, as shown in Figure 8B, the cut aggregate sheet 1 can be handled by the aggregate sheet support 10.

[0154] Therefore, the handling of the cut aggregate sheet 1 can be improved.

[0155] (9) According to the manufacturing method of the aggregate sheet 1, as shown in Figure 8B, the handling of the cut aggregate sheet 1 in the plating process can be improved.

[0156] 4. Variations Next, a modified example will be described. In the modified example, the same reference numerals are used for components similar to those in the above-described embodiment, and their descriptions are omitted.

[0157] (1) As shown in Figure 9, the aggregate sheet 100 may have reinforcing parts 4 that reinforce the edges of the through holes 31. Specifically, the aggregate sheet 100 has reinforcing parts 4A that reinforce the edge of the through hole 31A, reinforcing parts 4B that reinforce the edge of the through hole 31B, reinforcing parts 4C that reinforce the edge of the through hole 31C, and reinforcing parts 4D that reinforce the edge of the through hole 31D. The shapes of the reinforcing parts 4A, 4B, 4C, and 4D are not limited.

[0158] Because the edges of the through-hole 31 are reinforced by the reinforcing part 4, it is possible to prevent the frame 3 from tearing starting from the through-hole 31, and the aggregate sheet 1 can be stably suspended from the aggregate sheet support 10.

[0159] (2) The first spacer portion 113 does not have to be around the shaft portion 112. The first spacer portion 113 may be provided away from the shaft portion 112.

[0160] (3) In modified examples (1) and (2), the same effects as the embodiments described above can be obtained. [Explanation of Symbols]
