Description

Technical Field

[0001] The present disclosure relates to a circuit substrate manufacturing device and a circuit substrate manufacturing method. Background Art

[0002] Japanese Patent Publication No. 2003-48249 discloses a device that continuously presses and bonds two or more sheets with concave and convex shapes formed on at least one sheet under high vacuum, such as bonding a printed circuit board sheet with a concave and convex surface to its cover sheet. When using the device described in this document to bond two sheets together, first, the two sheets are placed between upper and lower pressing members and clamped between the upper and lower pressing members. At this time, the parts of the upper and lower pressing members that clamp the two sheets are completely sealed. When the two sheets are clamped and fixed by the upper and lower pressing members, and the lower surface of the sliding frame is tightly bonded to the upper surface of the support platform with high airtightness throughout the entire surface, an airtight partition chamber surrounded by the inner peripheral surface of the frame and the lower surface of the push block is formed on the support platform. Then, by evacuating the partition chamber, the bubbles between the two sheets can be removed. Then, the two sheets are further sandwiched between the support table and the push block and heated and pressed, thereby being thermocompression-bonded under high vacuum. Summary of the Invention

[0003] Problems to be solved by the invention

[0004] However, in circuit boards where the insulating layer is secured to a metal substrate through a press process, and the circuit portion is secured to the insulating layer through a press process, the insulating layer may be pressed toward the substrate via a sheet-like member during the press process. In such cases, the sheet-like member must be removed after the press process, but the device described in Japanese Patent Application Laid-Open No. 2003-48249 does not take this into account.

[0005] The present disclosure has been made in consideration of the above-mentioned circumstances, and an object of the present disclosure is to provide a circuit board manufacturing apparatus and a circuit board manufacturing method capable of removing sheet-like members.

[0006] Solutions for solving problems

[0007] For the manufacturing device of the circuit substrate of the first scheme, the circuit substrate comprises: a substrate formed using a metal material; an insulating layer formed into a sheet using an insulating material and fixed on the substrate; and a circuit portion formed using a conductive material and fixed on the insulating layer. The manufacturing device comprises: a peeling portion, which is provided on a path for conveying the substrate in a state where the insulating layer is fixed, and the peeling portion comprises an adsorption portion and an ejection portion, wherein the adsorption portion adsorbs the sheet-like component adhered to the insulating layer, and the ejection portion ejects air between the insulating layer and the sheet-like component.

[0008] The circuit board manufacturing apparatus according to the second aspect is the circuit board manufacturing apparatus according to the first aspect, wherein the peeling section includes a plurality of the adsorption sections arranged at intervals in the horizontal direction.

[0009] The circuit substrate manufacturing method of the third scheme uses the circuit substrate manufacturing device of the first scheme, which has: a peeling process, in which air is sprayed from the spray part to between the insulating layer and the sheet-like component while the sheet-like component is adsorbed by the adsorption part, thereby removing the sheet-like component.

[0010] With respect to the manufacturing method of the circuit substrate of the fourth scheme, in the manufacturing method of the circuit substrate of the third scheme, the manufacturing device of the circuit substrate of the second scheme is used, and in the stripping process, the plurality of adsorption parts respectively adsorb the plurality of sheet-like components located on the plurality of substrates to remove the plurality of sheet-like components.

[0011] The circuit board manufacturing apparatus of the first aspect can be applied to the manufacturing method of the third aspect, for example. In the manufacturing method of the third aspect, while the sheet-like member is being held by the suction unit, air is ejected from the ejection unit between the insulating layer and the sheet-like member to remove the sheet-like member (a peeling step). In this manner, the circuit board manufacturing apparatus of the first aspect can remove the sheet-like member.

[0012] The circuit board manufacturing apparatus of the second aspect can be applied to the manufacturing method of the fourth aspect, for example. In the fourth aspect, during the peeling step, multiple suction units each suction multiple sheet-like components located on multiple substrates to remove the multiple sheet-like components. This allows for simultaneous removal of multiple sheet-like components.

[0014] The circuit board manufacturing apparatus and circuit board manufacturing method disclosed herein have the excellent effect of being able to remove sheet-like members. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] use Figures 1 to 33 , a circuit substrate manufacturing apparatus 10 and a circuit substrate manufacturing method according to an embodiment of the present disclosure are described. It should be noted that the arrow UP shown in the figure indicates the upper side of the circuit substrate manufacturing apparatus 10. First, the schematic structure of the circuit substrate 12 is described, followed by a description of the structure of the circuit substrate manufacturing apparatus 10 and the circuit substrate manufacturing method.

[0053] (Schematic Structure of Circuit Board 12)

[0054] like Figure 1 and Figure 2 As shown, the circuit board 12 includes: a substrate 12 ; an insulating layer 16 fixed on the substrate 12 ; and a circuit portion 18 fixed on the insulating layer 16 .

[0055] The substrate 12 is formed of a metal material. It includes a rectangular plate-shaped portion 14A and a plurality of heat dissipation portions 14B protruding from the plate-shaped portion 14A. An insulating layer 16 and a circuit portion 18 are laminated and fixed to one side of the plate-shaped portion 14A in the thickness direction. The heat dissipation portions 14B protrude from the other side of the plate-shaped portion 14A in the thickness direction toward the side opposite to the plate-shaped portion 14A. For example, the heat dissipation portions 14B are cylindrical and regularly spaced apart.

[0056] The insulating layer 16 is formed in a sheet shape using an insulating material and is interposed between the plate-shaped portion 14A of the substrate 12 and the circuit portion 18 to ensure insulation between the two.

[0057] The circuit portion 18 is formed in a rectangular plate shape using a conductive material. In this embodiment, a plurality of circuit portions 18 formed in a predetermined pattern are fixed to the insulating layer 16 .

[0058] (Circuit Board Manufacturing Apparatus 10 and Circuit Board Manufacturing Method)

[0059] Figure 3 and Figure 4, a block diagram schematically showing a circuit substrate manufacturing apparatus 10 (hereinafter referred to as “manufacturing apparatus 10”) used in manufacturing the circuit substrate 12 is shown. Figure 3 As shown, the manufacturing apparatus 10 includes an insulation layer cutting unit 20, a first setting unit 22, a first preheating unit 24, a first pressing unit 26, a first unloading unit 28, a first cooling unit 30, a first peeling unit 32, and a first inspection unit 34. Figure 4 As shown, the manufacturing apparatus 10 includes a circuit portion attaching unit 36 , a second installation unit 38 , a second preheating unit 40 , a second pressurizing unit 42 , a second removing unit 44 , a second cooling unit 46 , a second peeling unit 48 , and a second inspection unit 50 .

[0060] like Figure 3 、 Figure 5 as well as Figure 6 As shown, in the insulation layer cutting portion 20, the insulation layer 16 is cut into a predetermined shape and size. Figure 5 As shown in FIG. 1 , the insulating layer 16 is formed into a sheet along a film 52 formed using polyethylene terephthalate (hereinafter referred to as PET film 52). It should be noted that the PET film 52 is a sheet-like member thinner than the insulating layer 16. Figure 6 As shown, the insulating layer cutting section 20 includes: a cutting table 54 for placing the insulating layer 16 together with the PET film 52; and a cutter 56 for cutting the insulating layer 16 placed on the cutting table 54 together with the PET film 52. Furthermore, in the process in the insulating layer cutting section 20, first, the insulating layer 16 is placed (set) on the cutting table 54 together with the PET film 52 in a state where the insulating layer 16 faces downward relative to the PET film 52. Then, the cutter 56 moves on the cutting table 54 along a prescribed trajectory, thereby cutting the insulating layer 16 together with the PET film 52 into a prescribed shape and size. It should be noted that Figure 6 The cut portion is depicted by a two-dot chain line. In this embodiment, by cutting the insulating layer 16 together with the PET film 52, deformation of the insulating layer 16 near the cut portion is suppressed compared to when the insulating layer 16 is cut alone. It should be noted that each process in the insulating layer cutting unit 20 can be performed entirely automatically, or partially or entirely manually.

[0061] like Figure 3 、 Figure 7 、 Figure 8 as well as Figure 9 As shown, in the first installation portion 22, the insulating layer 16 cut into a predetermined shape and size by the insulating layer cutting portion 20 is installed on the substrate 12. Figure 7 As shown, in the first setting portion 22, a conveying portion 66 (see Figure 10) for transporting and a positioning fixture 60 engaged with the common transport fixture 58. The common transport fixture 58 includes a substrate setting portion 58A for setting the substrate 12 in an embedded state. The positioning fixture 60 is formed of the same metal material as the common transport fixture 58. A rectangular positioning hole 60A is formed in the positioning fixture 60 in a manner that penetrates in the up and down directions. In addition, the positioning fixture 60 engages with the common transport fixture 58 from the upper side, thereby limiting the movement of the positioning fixture 60 relative to the common transport fixture 58 in the horizontal direction (the direction perpendicular to the up and down direction). In addition, in the process in the first setting portion 22, first, as Figure 8 As shown in FIG. 1 , the substrate 12 is placed on the substrate placement portion 58A of the common conveying jig 58 with the plurality of heat dissipation portions 14B facing downward. Figure 9 As shown, the positioning jig 60 is engaged with the co-conveying jig 58 from above. When the positioning jig 60 is engaged with the co-conveying jig 58, the portion of the plate-shaped portion 14A of the substrate 12 to which the insulating layer 16 is fixed is exposed upward through the positioning hole 60A. Next, an adhesive is applied to the surface of the insulating layer 16 opposite the PET film 52. Next, with the side of the insulating layer 16 coated with the adhesive facing downward, the insulating layer 16 is placed in the positioning hole 60A of the positioning jig 60, and the insulating layer 16 is placed on the plate-shaped portion 14A of the substrate 12 together with the PET film 52. Next, a metal plate 62 and thick paper 64, whose shape and size as viewed from above are set to correspond to the shape and size of the insulating layer 16, are placed in the positioning hole 60A of the positioning jig 60, and the metal plate 62 and thick paper 64 are placed on the insulating layer 16 (on the PET film 52). It should be noted that all the processes in the first setting part 22 can be performed automatically, or all or part of the processes in the first setting part 22 can be performed manually.

[0062] like Figure 3 and Figure 10 As shown, in the first preheating section 24, the substrate 12 and the insulating layer 16 are heated. Figure 10 As shown, the first preheating section 24 includes a heating furnace 68, which is arranged to surround the conveying section 66 that conveys the common conveyance jig 58. The temperature within the heating furnace 68 is maintained at a predetermined temperature. Furthermore, during the process in the first preheating section 24, the common conveyance jig 58 is conveyed by the conveying section 66, thereby moving the common conveyance jig 58 within the heating furnace 68. This heats the substrate 12 placed on the common conveyance jig 58 and the insulating layer 16 provided on the substrate 12.

[0063] like Figure 3 and Figures 11 to 22As shown, the first pressurizing unit 26 as the pressurizing unit presses the insulating layer 16 provided on the substrate 12 toward the substrate 12 via the PET film 52. Figure 11 and Figure 12 As shown, the first pressurizing unit 26 comprises: a pressurizing unit main body 70 having a mechanism for pressing an upper mold 86 to be described later toward a lower mold 84; a preparation unit 72 provided adjacent to the pressurizing unit main body 70; and a heating and pressurizing unit conveying unit 73 for moving a heating and pressurizing unit 74 to be described later and the like between the pressurizing unit main body 70 and the preparation unit 72. Figure 13 As shown, the first pressurizing unit 26 includes two heating and pressurizing units 74 on which the substrate 12 and the like are placed, and an air suction unit 76 .

[0064] like Figure 11 As shown, the pressurizing unit main body 70 includes a hydraulic cylinder 78 and an upper die engaging portion 80 supported by the hydraulic cylinder 78. An upper die 86, described later, is detachably engaged with the upper die engaging portion 80. Furthermore, as the hydraulic cylinder 78 operates, the upper die engaging portion 80 presses the upper die 86 downward. It should be noted that the hydraulic cylinder 78 in this embodiment is composed of a high-pressure cylinder 78A and a low-pressure cylinder 78B stacked in the vertical direction.

[0065] The preparation section 72 includes an upper die lifter 82 for lifting an upper die 86 described later. The upper die 86 can be lifted or lowered relative to the lower die 84 by the operation of the upper die lifter 82.

[0066] like Figure 11 and Figure 12 As shown, the heating and pressurizing section conveying section 73 includes: a rotating section 73A that can rotate in an axial direction with the up-down direction as the axial direction; and two lower mold engaging sections 73B fixed to the upper part of the rotating section 73A. The two heating and pressurizing sections 74 described later are respectively engaged with the two lower mold engaging sections 73B. Moreover, as the rotating section 73A rotates, the lower mold engaging section 73B on one side moves from the pressurizing section main body 70 to the preparation section 72, and the lower mold engaging section 73B on the other side moves from the preparation section 72 to the pressurizing section main body 70. As a result, the heating and pressurizing section 74 on the lower mold engaging section 73B on one side moves from the pressurizing section main body 70 to the preparation section 72, and the heating and pressurizing section 74 on the lower mold engaging section 73B on the other side moves from the preparation section 72 to the pressurizing section main body 70. The position on the lower die engaging portion 73B of the preparation portion 72 is referred to as “preparation position P1 ”, and the position on the lower die engaging portion 73B of the pressurizing portion main body 70 is referred to as “pressurizing position P2 ”.

[0067] like Figure 13 As shown in FIG, the two heating and pressing parts 74 have the same structure. Figure 131 and 2 show only the heating and pressing section 74 disposed on the side of the pressing section main body 70. The heating and pressing section 74 includes a lower mold 84, an upper mold 86 engaged with the lower mold 84, and a receiving jig 88 fixed to the lower mold 84 as a substrate placement portion.

[0068] The lower mold 84 includes: a lower plate portion 84A fixed to the lower mold engaging portion 73B; and a central protrusion 84B protruding upward from the horizontal center portion of the lower plate portion 84A. A receiving fixture 88, which will be described later, is fixed to the upper surface of the central protrusion 84B. In addition, a heater 90 for heating the lower mold 84 is provided on the lower plate portion 84A. Moreover, an O-ring 92 is mounted on the central protrusion 84B. A vacuum path 84C is formed between the lower plate portion 84A and the central protrusion 84B. One end side of the vacuum path 84C is open on the upper surface of the central protrusion 84B, and the other end side is connected to the air suction portion 76 such as a vacuum pump.

[0069] The upper mold 86 is arranged on the upper side relative to the lower mold 84. The upper mold 86 comprises: an upper plate portion 86A, which is detachably connected to the upper mold engaging portion 80 and the upper mold lifting portion 82 (see Figure 11 ) engages; and a peripheral wall portion 86B protrudes downward from the horizontal end of the upper plate portion 86A. Furthermore, the upper mold 86 engages with the lower mold 84 by moving the upper mold 86 toward the lower mold 84. When the upper mold 86 and the lower mold 84 are engaged, the central protrusion 84B of the lower mold 84 is positioned inside the peripheral wall portion 86B of the upper mold 86. This creates a sealed space 94 between the upper mold 86 and the lower mold 84, surrounding the receiving fixture 88. It should be noted that when the upper mold 86 and the lower mold 84 are engaged, the gap between the central protrusion 84B of the lower mold 84 and the peripheral wall portion 86B of the upper mold 86 is sealed by an O-ring 92. Furthermore, a heater 90 for heating the upper mold 86 is provided on the upper plate portion 86A. Furthermore, the upper mold 86 includes a concentrated pressing portion 86 that protrudes downward from the horizontal center portion of the upper plate portion 86A.

[0070] Figure 14 1 shows a top view of the receiving fixture 88 viewed from above. The receiving fixture 88 is formed in a rectangular block shape. In addition, a plurality of insertion holes 88A are formed in the receiving fixture 88 and are open on the upper side. These plurality of insertion holes 88A are connected to the plurality of heat dissipation portions 14B of the substrate 12 (see FIG. Figure 1 ) correspond to each other and are regularly arranged at prescribed intervals. Figure 15 As shown, with the plurality of heat dissipating portions 14B of the substrate 12 respectively inserted into the plurality of insertion holes 88A, the substrate 12 is placed on the receiving jig 88. When the substrate 12 is placed on the receiving jig 88, the lower surface of the plate-like portion 14A (the surface of the substrate 12 that constitutes the bottom surface of the plurality of heat dissipating portions 14B) contacts the upper surface of the receiving jig 88.

[0071] Then, if Figure 16 As shown, in the process in the first pressurizing section 26, first, the substrate 12 that has completed the process in the first preheating section 24 (passed through the heating furnace 68) is set to the heating and pressurizing section 74 arranged at the preparation position P1 (setting process). Here, the substrate 12 is moved together with the positioning fixture 60 and the like by a robot (not shown) and is set to the receiving fixture 88 arranged at the preparation position P1. Then, as shown in FIG. Figure 17 As shown, by operating the upper mold lifting unit 82, the upper mold 86 and the lower mold 84 are engaged at the preparation position P1 (first insulation layer fixing step). Here, the upper mold 86 and the lower mold 84 are heated to a predetermined temperature by the aforementioned heater 90. Furthermore, when the upper mold 86 and the lower mold 84 are engaged at the preparation position P1, the air suction unit 76 is activated to suck the air from the sealed space 94 between the upper mold 86 and the lower mold 84. In other words, the sealed space 94 between the upper mold 86 and the lower mold 84 is evacuated.

[0072] Then, if Figure 18 As shown, by rotating the rotating portion 73A, the heating and pressing portion 74 disposed at the preparation position P1 moves toward the pressing position P2. At this time, the heating and pressing portion 74 disposed at the pressing position P2 moves toward the preparation position P1 (second insulating layer fixing step).

[0073] Then, if Figure 19 As shown, the upper mold engaging portion 80 is engaged with the upper mold 86, and the upper mold 86 is pressed toward the lower mold 84 at the pressing position P2, thereby pressing the insulating layer 16 toward the substrate 12 via the PET film 52. This secures the insulating layer 16 to the substrate 12 (pressing step, third insulating layer securing step). It should be noted that during the third insulating layer securing step, the state of the insulating layer 16 being pressed toward the substrate 12 is maintained for a predetermined period of time. Furthermore, during the third insulating layer securing step, while the upper mold 86 and lower mold 84 are heated by the heater 90, the sealed space 94 between the upper mold 86 and lower mold 84 is evacuated.

[0074] Simultaneously (in parallel) with the third insulating layer fixing step, the substrate 12 that has completed the step in the first preheating section 24 (passed through the heating furnace 68) is set in the heating and pressing section 74 disposed at the preparation position P1 (setting step). Figure 20 As shown, by operating the upper mold lifting unit 82, the upper mold 86 and the lower mold 84 are engaged at the preparation position P1 (the fourth insulation layer fixing step). In addition, when the upper mold 86 and the lower mold 84 are engaged at the preparation position P1, the air suction unit 76 is operated to evacuate the sealed space 94 between the upper mold 86 and the lower mold 84.

[0075] Then, if Figure 21 As shown, after the upper mold engaging portion 80 and the upper mold 86 are disengaged, the rotating portion 73A is rotated, thereby moving the heating and pressing portion 74, which has completed the third insulating layer fixing step, from the pressing position P2 to the preparation position. At this time, the heating and pressing portion 74, which has completed the fourth insulating layer fixing step, moves from the preparation position P1 to the pressing position P2 (fifth insulating layer fixing step).

[0076] Then, if Figure 22 As shown, the upper mold engaging portion 80 is engaged with the upper mold 86, and the upper mold 86 is pressed toward the lower mold 84 at the pressing position P2, thereby pressing the insulating layer 16 toward the substrate 12 via the PET film 52. In this way, the insulating layer 16 is fixed to the substrate 12 (pressing step, sixth insulating layer fixing step).

[0077] Simultaneously (and in parallel) with the sixth insulating layer fixing step, the substrate 12 to which the insulating layer 16 is fixed is removed from the heating and pressing section 74 located at the preparation position P1 (removal step). Here, a robot (not shown) operates to move the substrate 12 together with the positioning jig 60 and the like, and removes the substrate 12 from the receiving jig 88 located at the preparation position P1. The substrate 12 removed from the receiving jig 88 is returned together with the positioning jig 60 and the like to the common conveying jig 58 on the conveying section 66. Next, the substrate 12 that has completed the process performed in the first preheating section 24 (passed through the heating furnace 68) is set in the heating and pressing section 74 located at the preparation position P1 (setting step, seventh insulating layer fixing step). In this manner, by repeating the first to seventh insulating layer fixing steps, the substrates 12 and the like that have completed the processes performed in the first preheating section 24 are sequentially placed in the first pressurizing section 26. Furthermore, the substrates 12 and the like placed in the first pressurizing section 26 are sequentially sent to the next step.

[0078] In the first pressurizing section 26 of the manufacturing apparatus 10 of this embodiment, the third and fourth insulating layer fixing steps can be performed simultaneously. Furthermore, the sixth and seventh insulating layer fixing steps can be performed simultaneously. This prevents the waiting time before the steps of fixing the substrate 12 and the insulating layer 16 from being prolonged. Specifically, while the insulating layer 16 is pressed toward the substrate 12 at pressurizing position P2, the substrate 12 with the insulating layer 16 fixed thereto can be removed from the heating and pressurizing section 74 at the preparation position P1. Furthermore, while the insulating layer 16 is pressed toward the substrate 12 at pressurizing position P2, the substrate 12 before the insulating layer 16 is fixed can be placed in the heating and pressurizing section 74 at the preparation position P1. Furthermore, while the insulating layer 16 is pressed toward the substrate 12 at pressurizing position P2, the substrate 12 before the insulating layer 16 is fixed can be heated at the preparation position P1 using heaters 90 provided in the upper mold 86 and lower mold 84, respectively. Furthermore, while insulating layer 16 is being pressed toward substrate 12 at pressurizing position P2, enclosed space 94 formed between upper mold 86 and lower mold 84 can be evacuated at preparation position P1. Thus, in this embodiment, the time required to wait idly before placing substrate 12 or the like, which has completed the process in first preheating section 24, into first pressurizing section 26 can be reduced.

[0079] In addition, in this embodiment, if Figure 15 As shown, the substrate 12 is placed on the receiving jig 88, with the plurality of heat dissipating portions 14B of the substrate 12 respectively inserted into the plurality of insertion holes 88A of the receiving jig 88. When the substrate 12 is placed on the receiving jig 88, the lower surface of the plate-shaped portion 14A (the surface of the substrate 12 that constitutes the bottom surface of the plurality of heat dissipating portions 14B) contacts the upper surface of the receiving jig 88. Thus, the bottom surface of the plurality of heat dissipating portions 14B in the substrate 12 can be supported by the upper surface of the receiving jig 88. As a result, even when using a metal substrate 12 having a plurality of heat dissipating portions 14B formed in a convex shape, it is possible to pressurize the fixed portion of the insulating layer 16.

[0080] Furthermore, in this embodiment, the concentrated pressing portion 86 of the upper mold 86 is inserted into the positioning hole 60A of the positioning jig 60, thereby pressing the portion of the plate-shaped portion 14A of the substrate 12 on which the insulating layer 16 is placed. This allows the portion of the plate-shaped portion 14A of the substrate 12 on which the insulating layer 16 is placed to be pressed at a precise pinpoint.

[0081] Furthermore, in this embodiment, the concentrated pressing portion 86 of the upper mold 86 presses the portion of the plate-shaped portion 14A of the substrate 12 where the insulating layer 16 is placed, through the thick paper 64 and the metal plate 62. This allows the portion of the plate-shaped portion 14A of the substrate 12 where the insulating layer 16 is placed to be pressed evenly. Furthermore, by placing the metal plate 62 between the thick paper 64 and the insulating layer 16 (PET film 52), the unevenness of the thick paper 64 can be prevented from being transferred to the insulating layer 16.

[0082] Furthermore, in this embodiment, air suction unit 76 can suction air from sealed space 94 formed between lower mold 84 and upper mold 86. This allows for faster vacuuming around the area where insulating layer 16 is fixed, compared to a configuration in which air outside lower mold 84 and upper mold 86 is also suctioned in order to suction air from sealed space 94 formed between lower mold 84 and upper mold 86.

[0083] Furthermore, in the present embodiment, the substrate 12 and the like are heated in the process in the first preheating section 24. This can shorten the time required to heat the substrate 12 and the like in the process in the first pressurizing section 26.

[0084] It should be noted that all the steps in the first pressurizing unit 26 described above may be performed automatically, or part of the steps in the first pressurizing unit 26 may be performed manually.

[0085] like Figure 3 and Figure 23 As shown, in the first unloading section 28, the positioning jig 60 is unloaded from the common transport jig 58 transported from the first pressurizing section 26. Furthermore, in the first unloading section 28, the metal plate 62 and thick paper 64 placed on the insulating layer 16 are unloaded. It should be noted that the processes in the first unloading section 28 can be performed entirely automatically, or partially or entirely manually.

[0086] like Figure 3 and Figure 24 As shown, in the first cooling unit 30, the substrate 12 and the insulating layer 16 are cooled. Figure 24 As shown, the first cooling unit 30 includes fans 96 located above and below the conveyor unit 66 that conveys the shared transport jig 58. During the process in the first cooling unit 30, the shared transport jig 58 is conveyed by the conveyor unit 66, passing between the upper and lower fans 96. This cools the substrate 12 placed on the shared transport jig 58 and the insulating layer 16 secured thereto.

[0087] like Figure 3 and Figure 25As shown, in the first peeling portion 32 as the peeling portion, the PET film 52 is removed from the insulating layer 16. Figure 25 As shown, the first peeling section 32 includes: a suction section 98 for sucking the PET film 52; and a nozzle 100 as a spray section for spraying compressed air between the PET film 52 and the insulating layer 16. Furthermore, during the process in the first peeling section 32, the suction section 98 first sucks the horizontal center portion of the PET film 52. Next, the suction section 98 is moved while spraying compressed air between the PET film 52 and the insulating layer 16 from the nozzle 100. As a result, the PET film 52 adhered to the insulating layer 16 is peeled off from the insulating layer 16 (peeling process). It should be noted that the PET film 52 peeled off from the insulating layer 16 is transported by the suction section 98 and discarded into a predetermined container. It should be noted that the processes in the first peeling section 32 can be performed entirely automatically, or partially or entirely manually.

[0088] like Figure 3 and Figure 26 As shown, in the first inspection unit 34, it is inspected whether the insulating layer 16 is fixed to a predetermined position in the substrate 12. Figure 26 As shown, the first inspection unit 34 includes a camera 102. In addition, in the process in the first inspection unit 34, the images of the substrate 12 and the insulating layer 16 captured by the camera 102 are compared with the inspection data, thereby inspecting whether the insulating layer 16 is fixed to the specified position in the substrate 12. When the inspection result shows that the insulating layer 16 is fixed to the specified position in the substrate 12, the substrate 12 with the insulating layer 16 fixed thereto is conveyed to the next process. On the other hand, when the inspection result shows that the insulating layer 16 is not fixed to the specified position in the substrate 12, the substrate 12 with the insulating layer 16 fixed thereto is not conveyed to the next process and is discarded. It should be noted that the processes in the first inspection unit 34 can be performed entirely automatically, or partially or entirely manually.

[0089] like Figure 4 and Figure 27 As shown, in the circuit portion pasting portion 36, the circuit portion 18 is pasted to the polyurethane sheet 104. Figure 27As shown, the shape and size of the polyurethane sheet 104 as viewed in the thickness direction are set to correspond to the shape and size of the insulating layer 16. An adhesive layer to which the circuit portion 18 can be attached is formed on one side of the polyurethane sheet 104. Then, in the process in the circuit portion attaching section 36, the circuit portion 18 is attached to a predetermined position on the surface of the polyurethane sheet 104 on which the adhesive layer is formed. In this way, the circuit portion 18 is fixed to the polyurethane sheet 104. It should be noted that the processes in the circuit portion attaching section 36 can be performed entirely automatically, or partially or entirely manually.

[0090] like Figure 4 and Figure 28 As shown, in the second installation portion 38 , the circuit portion 18 fixed to the polyurethane sheet 104 is installed on the insulating layer 16 fixed to the substrate 12 .

[0091] In the process in the second installation section 38, adhesive is applied to the surface of the circuit section 18 opposite the polyurethane sheet 104. Alternatively, adhesive is applied to the portion of the insulating layer 16 to which the circuit section 18 is to be fixed. Next, with the surface of the circuit section 18 opposite the polyurethane sheet 104 facing downward, the circuit section 18 and the polyurethane sheet 104 are placed on the insulating layer 16. Next, thick paper 64 is placed on the polyurethane sheet 104. It should be noted that the various processes in the second installation section 38 can be performed entirely automatically, or partially or entirely manually.

[0092] like Figure 4 As shown, in the second preheating section 40, the substrate 12, the insulating layer 16, and the circuit section 18 are heated. It should be noted that the process in the second preheating section 40 is the same as the process in the first preheating section 24. That is, in the process in the second preheating section 40, the common transport jig 58 is transported by the transport section 66, thereby moving the common transport jig 58 in the heating furnace 68 (refer to Figure 10 ). Thus, the substrate 12, the insulating layer 16, the circuit portion 18, and the like placed on the common transport jig 58 are heated.

[0093] like Figure 4 As shown, in the second pressurizing unit 42, the circuit unit 18 provided on the insulating layer 16 is pressed toward the substrate 12. In the process in the second pressurizing unit 42, similarly to the process in the first pressurizing unit 26, the circuit unit 18 is pressed toward the substrate 12. Figures 11 to 14The pressurizing section main body 70, the preparation section 72, the heating and pressing section transport section 73, the two heating and pressing sections 74, and the air suction section 76 are shown. Here, each process in the second pressurizing section 42 is similar to each process in the first pressurizing section 26. Therefore, in the description of each process in the second pressurizing section 42, the same figures as those used in the description of each process in the first pressurizing section 26 are used.

[0094] like Figure 16 As shown, in the process in the second press section 42, first, the substrate 12 that has completed the process in the second preheating section 40 (passed through the heating furnace 68) is set to the heating and press section 74 arranged at the preparation position P1. Here, a robot (not shown) operates to set the substrate 12 to the receiving fixture 88 arranged at the preparation position P1. Then, as shown in FIG. Figure 17 As shown, by operating the upper mold lifting unit 82, the upper mold 86 and the lower mold 84 are engaged at the preparation position P1 (first circuit unit fixing step). Here, the upper mold 86 and the lower mold 84 are heated to a predetermined temperature by the aforementioned heater 90. Furthermore, when the upper mold 86 and the lower mold 84 are engaged at the preparation position P1, the air suction unit 76 is activated to suck the air from the sealed space 94 between the upper mold 86 and the lower mold 84. In other words, the sealed space 94 between the upper mold 86 and the lower mold 84 is evacuated.

[0095] Then, if Figure 18 As shown, by rotating the rotating portion 73A, the heating and pressing portion 74 disposed at the preparation position P1 moves toward the pressing position P2. At this time, the heating and pressing portion 74 disposed at the pressing position P2 moves toward the preparation position P1 (second circuit unit fixing step).

[0096] Then, if Figure 19 As shown, the upper mold engaging portion 80 is engaged with the upper mold 86, and the upper mold 86 is pressed toward the lower mold 84 at the pressurizing position P2, thereby pressing the circuit portion 18 provided on the insulating layer 16 toward the substrate 12. In this way, the circuit portion 18 is fixed to the insulating layer 16 (third circuit portion fixing process). It should be noted that in the third circuit portion fixing process, the state of pressing the circuit portion 18 toward the substrate 12 side is maintained for a predetermined time. In addition, in the third circuit portion fixing process, the circuit portion 18 is pressed toward the substrate 12 side with a pressure lower than that in the aforementioned third insulating layer fixing process. Therefore, as an example, only the high-pressure cylinder 78A is operated in the third insulating layer fixing process, or only the low-pressure cylinder 78B is operated in the third circuit portion fixing process. In addition, in the third circuit portion fixing process, while the upper mold 86 and the lower mold 84 are heated by the heater 90, the enclosed space 94 between the upper mold 86 and the lower mold 84 is also vacuumed.

[0097] Simultaneously (in parallel) with the third circuit unit fixing step, the substrate 12 that has completed the step in the second preheating unit 40 (passed through the heating furnace 68) is set in the heating and pressing unit 74 disposed at the preparation position P1. Figure 20 As shown, by operating the upper mold lifting unit 82, the upper mold 86 and the lower mold 84 are engaged at the preparation position P1 (the fourth circuit unit fixing step). In addition, when the upper mold 86 and the lower mold 84 are engaged at the preparation position P1, the air suction unit 76 is operated to vacuum the enclosed space 94 between the upper mold 86 and the lower mold 84.

[0098] Then, if Figure 21 As shown, after the upper mold engaging portion 80 and the upper mold 86 are released, the rotating portion 73A is rotated, thereby moving the heating and pressing portion 74 that has completed the third circuit unit fixing process from the pressing position P2 to the preparation position side. At this time, the heating and pressing portion 74 that has completed the fourth circuit unit fixing process moves from the preparation position P1 to the pressing position P2 side (fifth circuit unit fixing process).

[0099] Then, if Figure 22 As shown, the upper mold engaging portion 80 is engaged with the upper mold 86, and the upper mold 86 is pressed toward the lower mold 84 at the pressing position P2, thereby pressing the circuit portion 18 provided on the insulating layer 16 toward the substrate 12. In this way, the circuit portion 18 is fixed to the insulating layer 16 (the sixth circuit portion fixing step).

[0100] Simultaneously (in parallel) with the sixth circuit unit fixing process, the substrate 12 in a state where the circuit unit 18 is fixed on the insulating layer 16 is removed from the heating and pressing section 74 arranged at the preparation position P1. Here, the substrate 12 is removed from the receiving fixture 88 arranged at the preparation position P1 by a robot not shown in the figure. The substrate 12 removed from the receiving fixture 88 is returned to the common conveying fixture 58 on the conveying section 66 again. Next, the substrate 12 that has completed the process performed by the second preheating section 40 (passed through the heating furnace 68) is set to the heating and pressing section 74 arranged at the preparation position P1 (setting process, seventh circuit unit fixing process). In this way, by repeatedly performing the first circuit unit fixing process to the seventh circuit unit fixing process, the substrates 12 and the like that have completed the process performed by the second preheating section 40 are sequentially put into the second pressing section 42. In addition, the substrates 12 and the like that have been put into the second pressing section 42 are sequentially sent to the next process.

[0101] Here, in the second pressurizing portion 42 of the manufacturing device 10 of the present embodiment, the third circuit portion fixing process and the fourth circuit portion fixing process can be performed simultaneously. In addition, the sixth circuit portion fixing process and the seventh circuit portion fixing process can be performed simultaneously. Thus, it is possible to suppress the waiting time before the process of fixing the circuit portion 18 and the insulating layer 16 from becoming longer. In detail, when the circuit portion 18 is pressed toward the substrate 12 side at the pressurizing position P2, the operation of removing the substrate 12 with the circuit portion 18 fixed on the insulating layer 16 from the heating and pressing portion 74 can be performed on the preparation position P1 side. In addition, when the circuit portion 18 is pressed toward the substrate 12 side at the pressurizing position P2, the substrate 12 with the circuit portion 18 provided on the insulating layer 16 can be set to the heating and pressing portion 74 on the preparation position P1 side. Furthermore, while the circuit portion 18 is pressed toward the substrate 12 at the pressurizing position P2, the substrate 12, etc., with the circuit portion 18 provided on the insulating layer 16, can be heated by heaters 90 provided in the upper mold 86 and the lower mold 84, respectively, at the preparation position P1. Furthermore, while the circuit portion 18 is pressed toward the substrate 12 at the pressurizing position P2, the enclosed space 94 formed between the upper mold 86 and the lower mold 84 can be evacuated at the preparation position P1. Thus, in this embodiment, the time spent waiting idly before the substrate 12, etc., which has completed the process in the second preheating section 40, is placed into the second pressurizing section 42 can be reduced.

[0102] In addition, in this embodiment, if Figure 29 As shown, the substrate 12 is placed on the receiving jig 88, with the plurality of heat dissipating portions 14B of the substrate 12 respectively inserted into the plurality of insertion holes 88A of the receiving jig 88. When the substrate 12 is placed on the receiving jig 88, the lower surface of the plate-shaped portion 14A (the surface of the substrate 12 that constitutes the bottom surface of the plurality of heat dissipating portions 14B) contacts the upper surface of the receiving jig 88. Thus, the bottom surface of the plurality of heat dissipating portions 14B in the substrate 12 can be supported by the upper surface of the receiving jig 88. As a result, even when a metal substrate 12 having a plurality of heat dissipating portions 14B formed in a convex shape is used, it is possible to pressurize the fixed portion of the circuit portion 18.

[0103] Furthermore, in this embodiment, the concentrated pressing portion 86 of the upper mold 86 intensively presses the portion where the circuit portion 18 is provided. This allows the portion where the circuit portion 18 is provided to be pressed with precise positioning.

[0104] Furthermore, in this embodiment, the concentrated pressing portion 86 of the upper mold 86 presses the portion where the circuit portion 18 is located, through the thick paper 64 and the polyurethane sheet 104. When the polyurethane sheet 104 is pressed toward the substrate 12 through the thick paper 64, a portion of the polyurethane sheet 104 comes into contact with the insulating layer 16, pressing the insulating layer 16 downward. This prevents swelling in the portion of the insulating layer 16 where the circuit portion 18 is not secured. Furthermore, the polyurethane sheet absorbs any adhesive that may have overflowed from between the insulating layer 16 and the circuit portion 18.

[0105] Furthermore, in this embodiment, the air in the sealed space 94 formed between the lower mold 84 and the upper mold 86 can be sucked by the air suction portion 76. This allows for faster vacuuming around the fixing portion of the circuit portion 18, compared to a configuration in which the air in the space outside the lower mold 84 and the upper mold 86 is also sucked in order to suck the air in the sealed space 94 formed between the lower mold 84 and the upper mold 86.

[0106] Furthermore, in this embodiment, the substrate 12 and the like are heated in the process in the second preheating section 40 . This can shorten the time required to heat the substrate 12 and the like in the process in the second pressurizing section 42 .

[0107] It should be noted that the various processes in the second pressurizing unit 42 described above may all be performed automatically, or may be partially performed manually.

[0108] like Figure 4 and Figure 30 As shown, the thick paper 64 placed on the polyurethane sheet 104 is removed in the second removal section 44. It should be noted that the processes in the second removal section 44 can be performed entirely automatically, or partially or entirely manually.

[0109] like Figure 4 and Figure 31 As shown, in the second cooling unit 46, the substrate 12, the insulating layer 16 and the circuit unit 18 are cooled. Figure 31 As shown, during the process in the second cooling unit 46, the common transport jig 58 is transported by the transport unit 66, thereby passing the common transport jig 58 between the upper and lower fans 96. As a result, the substrate 12 placed on the common transport jig 58, the insulating layer 16 fixed to the substrate 12, and the circuit unit 18 fixed to the insulating layer 16 are cooled.

[0110] like Figure 4 and Figure 32 As shown, in the second peeling section 48, the polyurethane sheet 104 is removed. Figure 32As shown, the second peeling section 48 includes a gripping section 106 for gripping the polyurethane sheet 104. Furthermore, in the process in the second peeling section 48, first, the gripping section 106 grips the end portion of the polyurethane sheet 104. Then, the gripping section 106 gripping the end portion of the polyurethane sheet 104 is moved. As a result, the polyurethane sheet 104 is peeled off from the circuit section 18 and the insulating layer 16. It should be noted that the polyurethane sheet 104 peeled off from the circuit section 18 and the insulating layer 16 is transported by the gripping section 106 and discarded into a specified container. It should be noted that the processes in the second peeling section 48 can be performed entirely automatically, or the processes in the second peeling section 48 can be performed partially or entirely manually.

[0111] like Figure 4 and Figure 33 As shown, in the second inspection unit 50, it is inspected whether the circuit unit 18 is fixed to a predetermined position on the substrate 12. Figure 33 As shown, in the process in the second inspection section 50, the images of the substrate 12, the insulating layer 16, and the circuit portion 18 captured by the camera 102 are compared with the inspection data, thereby inspecting whether the circuit portion 18 is fixed at a specified position in the substrate 12. In the case where the inspection result shows that the circuit portion 18 is fixed at a specified position in the substrate 12, the substrate 12 (circuit substrate 12) with the circuit portion 18 fixed to the insulating layer 16 is shipped as a product. In contrast, in the case where the inspection result shows that the circuit portion 18 is not fixed at a specified position in the substrate 12, the substrate 12 (circuit substrate 12) with the circuit portion 18 fixed to the insulating layer 16 is not shipped as a product and is discarded. It should be noted that the processes in the second inspection section 50 can be performed entirely automatically, or the processes in the second inspection section 50 can be performed partially or entirely manually.

[0112] Through the above-described steps, the Figure 1 and Figure 2 The circuit substrate 12 is shown.

[0113] It should be noted that the details and each process of the manufacturing apparatus 10 described above may be changed according to the configuration of the circuit board 12 .

[0114] In addition, you can Figure 3 The insulating layer cutting unit 20, the first setting unit 22, the first preheating unit 24, the first pressing unit 26, the first removing unit 28, the first cooling unit 30, the first stripping unit 32 and the first inspection unit 34 are shown. Figure 4 The circuit portion pasting section 36, second setting section 38, second preheating section 40, second pressurizing section 42, second removal section 44, second cooling section 46, second peeling section 48 and second inspection section 50 shown are provided as common equipment, or as equipment provided separately.

[0115] (Other methods)

[0116] Next, use Figures 34 to 37 The first peeling unit 32 of the circuit board manufacturing apparatus according to another embodiment of the present disclosure will be described. Note that in the following description, descriptions of components and parts corresponding to the already described circuit board 12 and circuit board manufacturing apparatus 10 may be omitted.

[0117] like Figure 34 As shown, the first peeling unit 32 of this embodiment is moved vertically and horizontally by a moving mechanism (not shown). Specifically, the first peeling unit 32 includes a main shaft 110 supported by the moving mechanism (not shown); a support arm 112 fixed to the main shaft 110; and two suction units 98 supported by the support arm 112.

[0118] The support arm portion 112 is formed in a rectangular shape with its longitudinal direction being the horizontal direction. The longitudinal center portion of the support arm portion 112 is fixed to the lower end portion of the main shaft portion 110 .

[0119] The two adsorption units 98 have substantially the same configuration. Therefore, the configuration of one adsorption unit 98 will be described below, and the description of the configuration of the other adsorption unit 98 may be omitted.

[0120] The adsorption portion 98 includes an adsorption shaft portion 114 , an adsorption pad support portion 116 supported by the adsorption shaft portion 114 , and four adsorption pads 118 supported by the adsorption pad support portion 116 .

[0121] The suction pad support portion 116 is formed into a plate-like shape with its thickness extending in the vertical direction and extending horizontally. When viewed from above, it forms a cross shape. Specifically, the suction pad support portion 116 comprises a fixed plate portion 116A fixed to the lower end of the suction shaft portion 114, and four support plates 116B extending from the outer periphery of the fixed plate portion 116A toward the side opposite to the fixed plate portion 116A. The four support plates 116B are arranged at 90-degree intervals around the fixed plate portion 116A.

[0122] The suction pads 118 are threaded suction pads with corrugated sections in the middle in the vertical direction. Their lower ends provide suction to the PET film 52. Furthermore, the four suction pads 118 are supported on the ends of the four support plates 116B opposite the fixed plate 116A. It should be noted that the four suction pads 118 are connected to piping 120 for suctioning air from their lower surfaces.

[0123] One suction portion 98 is fixed to one side of the longitudinal dimension of the support arm 112. Furthermore, the other suction portion 98 is fixed to the other side of the longitudinal dimension of the support arm 112. Thus, the suction portion 98 on one side and the suction portion 98 on the other side are arranged side by side in the horizontal direction. It should be noted that the horizontal spacing between the suction portion 98 on one side and the suction portion 98 on the other side can also be adjusted.

[0124] In the first peeling unit 32 of the present embodiment described above, the substrate 14 with the insulating layer 16 fixed thereto is first conveyed below the first peeling unit 32. Here, two substrates 14 with the insulating layer 16 fixed thereto are conveyed below the first peeling unit 32.

[0125] Then, if Figure 35 As shown, the first peeling unit 32 is lowered, thereby causing the four adsorption pads 118 of one adsorption unit 98 to contact the PET film 52 located on one substrate 14, and causing the four adsorption pads 118 of the other adsorption unit 98 to contact the PET film 52 located on the other substrate 14.

[0126] Next, the PET film 52 is sucked by the four suction pads 118 of one suction section 98 , and the PET film 52 on the other substrate 14 is sucked by the four suction pads 118 of the other suction section 98 .

[0127] Then, if Figure 36 As shown, compressed air is ejected from nozzle 100 between the PET film 52 on one substrate 14 and the insulating layer 16. Simultaneously, compressed air is ejected from nozzle 100 between the PET film 52 on the other substrate 14 and the insulating layer 16. As a result, the PET film 52 on each substrate 14 begins to peel from the insulating layer 16.

[0128] Then, if Figure 37 As shown, the first peeling unit 32 is raised, thereby completely peeling the PET film 52 on each substrate 14 from the insulating layer 16. Through the above steps, the PET film 52 on each substrate 14 is removed from the insulating layer 16 (peeling step). In this way, the first peeling unit 32 of this embodiment can also remove the PET film 52 after the pressing step performed by the first pressing unit 26.

[0129] Furthermore, the first peeling unit 32 of this embodiment can simultaneously remove two PET films 52 on two substrates 14. Note that, by increasing the number of adsorption units 98, three or more PET films 52 on three or more substrates 14 can be simultaneously removed.

[0130] In the first peeling unit 32 of this embodiment, one suction unit 98 includes a plurality of suction pads 118. This allows the suction pad 118 to suction the PET film 52 in a more stable state than when one suction unit 98 includes one suction pad 118.

[0131] As mentioned above, one embodiment of the present disclosure has been described, but the present disclosure is not limited to the above contents, and various modifications other than the above can be implemented without departing from the scope of the present disclosure.

[0132] The disclosure of Japanese Patent Application No. 2023-001923 filed on January 10, 2023 is incorporated herein by reference in its entirety.
