- the base 29 is generally rectangular in shape, and in the following description, the longitudinal direction of the base 29 is referred to as the X-axis direction, the lateral direction of the base 29 as the Y-axis direction, and the direction perpendicular to both the X-axis direction and the Y-axis direction as the Z-axis direction.
- the transport device 20 includes an X-axis slide mechanism 30 and a Y-axis slide mechanism 32.

- the X-axis slide mechanism 30 also includes an electromagnetic motor (see FIG. 2) 38, and the X-axis slider 36 is moved to any position in the X-axis direction by the drive of the electromagnetic motor 38.
- the Y-axis slide mechanism 32 also includes a Y-axis slide rail 50 and a stage 52.
- the Y-axis slide rail 50 is disposed on the base 29 so as to extend in the Y-axis direction and is movable in the X-axis direction.
- One end of the Y-axis slide rail 50 is connected to the X-axis slider 36.

- the Y-axis slide mechanism 32 has an electromagnetic motor (see FIG. 2) 56, and the stage 52 moves to any position in the Y-axis direction by driving the electromagnetic motor 56. As a result, the stage 52 moves to any position on the base 29 by driving the X-axis slide mechanism 30 and the Y-axis slide mechanism 32.
- the stage 52 has a base 60, a holding device 62, a lifting device (see FIG. 2) 64, and a heater (see FIG. 2) 66.
- the base 60 is formed in a flat plate shape, and a substrate is placed on the upper surface.
- the holding devices 62 are provided on both sides of the base 60 in the X-axis direction.
- the substrate is fixedly held by clamping both edges in the X-axis direction of the substrate placed on the base 60 between the holding devices 62.
- the lifting device 64 is disposed below the base 60, and raises and lowers the base 60.
- the heater 66 is built into the base 60, and heats the substrate placed on the base 60 to a desired temperature.
- the first modeling unit 22 is a unit that models the wiring of the circuit board, and has a first printing section 72 and a baking section 74.
- the first printing section 72 has an inkjet head (see FIG. 2) 76 that ejects metal ink in lines.
- the metal ink is a dispersion of nanometer-sized metal particles, such as silver particles, in a solvent. The surfaces of the metal particles are coated with a dispersant to prevent aggregation in the solvent.
- the inkjet head 76 ejects the metal ink from multiple nozzles, for example, by a piezo method using piezoelectric elements.
- the baking section 74 has an infrared irradiation device 78 (see Figure 2).
- the infrared irradiation device 78 is a device that irradiates the ejected metal ink with infrared rays.
- the metal ink irradiated with infrared rays is baked, and wiring is formed.
- baking of metal ink is a phenomenon in which, by applying energy, the solvent is evaporated and the protective film for the metal particles, i.e., the dispersant is decomposed, and the metal particles come into contact or fuse together, thereby increasing the conductivity. Then, by baking the metal ink, metal wiring is formed.
- the second modeling unit 23 is a unit that models the resin layer of the circuit board, and has a second printing unit 84 and a curing unit 86.
- the second printing unit 84 has an inkjet head (see FIG. 2) 88 that ejects ultraviolet curable resin.
- the ultraviolet curable resin is a resin that hardens when exposed to ultraviolet light.
- the inkjet head 88 may be, for example, a piezo type that uses a piezoelectric element, or a thermal type that heats the resin to generate bubbles and ejects the resin from multiple nozzles.
- the curing section 86 has a flattening device (see FIG. 2) 90 and an irradiation device (see FIG. 2) 92.
- the flattening device 90 flattens the top surface of the UV-curable resin discharged by the inkjet head 88, for example by leveling the surface of the UV-curable resin while scraping off excess resin with a roller or blade, thereby making the thickness of the UV-curable resin uniform.
- the irradiation device 92 has a mercury lamp or LED as a light source, and irradiates the discharged UV-curable resin with ultraviolet light. This hardens the discharged UV-curable resin, forming a resin layer.
- the third modeling unit 24 is a unit that models the connection parts between the electrodes of electronic components and the wiring on the circuit board, and has a third printing unit 100.
- the third printing unit 100 has a dispenser (see FIG. 2) 106 that dispenses conductive paste.
- the conductive paste is a resin that hardens when heated at a relatively low temperature, with micrometer-sized metal particles dispersed in it. Incidentally, the metal particles are in the form of flakes, and the viscosity of the conductive paste is relatively high compared to metal ink.
- the conductive paste dispensed by the dispenser 106 is then heated by the heater 66 built into the base 60.
- the resin in the heated conductive paste hardens.
- the resin in the conductive paste hardens and shrinks, and the flake-shaped metal particles dispersed in the resin come into contact with each other. This causes the conductive paste to exhibit conductivity.
- the resin in the conductive paste is an organic adhesive, and exerts adhesive power by hardening when heated.
- the fourth modeling unit 25 is a unit that models resin for fixing electronic components to a circuit board, and has a fourth printing unit 110.
- the fourth printing unit 110 has a dispenser 116 (see FIG. 2), which dispenses thermosetting resin.
- Thermosetting resin is resin that hardens when heated.
- the dispenser 116 is, for example, an air pulse type that uses compressed air.
- the thermosetting resin dispensed by the dispenser 116 is heated by a heater 66 built into the base 60 and hardens.
- the pressing unit 26 is a unit for pressing the circuit board, and has a pressing section 120.
- the pressing section 120 has a pressing plate (see FIG. 11) 122, a rubber plate (see FIG. 11) 124, and a cylinder (see FIG. 2) 126.
- the rubber plate 124 is molded, for example, from silicon rubber and has a plate shape.
- the pressing plate 122 is molded, for example, from steel and has a plate shape.
- the rubber plate 124 is attached to the underside of the pressing plate 122, and the pressing plate 122 is pressed against the circuit board by the operation of the cylinder 126. As a result, the circuit board is pressed by the pressing plate 122 via the rubber plate 124.
- the force pressing the board can be controllably changed by controlling the operation of the cylinder 126.
- the mounting unit 27 is a unit that mounts electronic components on a circuit board, and has a supply section 130 and a mounting section 132.
- the supply section 130 has multiple tape feeders (see FIG. 2) 134 that feed taped electronic components one by one, and supplies the electronic components at a supply position.
- the supply section 130 is not limited to tape feeders 134, and may be a tray-type supply device that picks up and supplies electronic components from a tray.
- the supply section 130 may also be configured to include both tape-type and tray-type supply devices, or other types of supply devices.
- the mounting section 132 has a mounting head (see FIG. 2) 136 and a moving device (see FIG. 2) 138.
- the mounting head 136 has a suction nozzle (not shown) for suctioning and holding electronic components.
- the suction nozzle sucks and holds the electronic component by sucking air when negative pressure is supplied from a positive and negative pressure supply device (not shown).
- the positive and negative pressure supply device then supplies a slight positive pressure to release the electronic component.
- the moving device 138 also moves the mounting head 136 between the supply position of electronic components by the tape feeder 134 and the board placed on the base 60. As a result, in the mounting section 132, the electronic component supplied from the tape feeder 134 is held by the suction nozzle, and the electronic component held by the suction nozzle is mounted on the board.
- the control device 28 includes a controller 140 and a plurality of drive circuits 142.
- the plurality of drive circuits 142 are connected to the electromagnetic motors 38, 56, the holding device 62, the lifting device 64, the heater 66, the inkjet head 76, the infrared irradiation device 78, the inkjet head 88, the flattening device 90, the irradiation device 92, the dispenser 106, the dispenser 116, the cylinder 126, the tape feeder 134, the mounting head 136, and the moving device 138.
- the controller 140 includes a CPU, ROM, RAM, etc., and is mainly a computer, and is connected to the plurality of drive circuits 142. As a result, the operation of the transport device 20, the first modeling unit 22, the second modeling unit 23, the third modeling unit 24, the fourth modeling unit 25, the pressing unit 26, and the mounting unit 27 is controlled by the controller 140.
- a resin laminate is formed on the base 60 using the above-mentioned configuration, and wiring is formed on the upper surface of the resin laminate.
- the electrodes of the electronic components are electrically connected to the wiring via the conductive paste, and the electronic components are fixed with resin.
- a circuit board is formed by stacking multiple electronic components.
- a process for forming a circuit board will now be described. Specifically, first, the stage 52 is moved below the second modeling unit 23. Then, in the second modeling unit 23, as shown in FIG. 3, a resin laminate 152 is formed on the base 60 of the stage 52.
- the resin laminate 152 is formed by repeatedly ejecting ultraviolet curable resin from the inkjet head 88 and irradiating the ejected ultraviolet curable resin with ultraviolet light by the irradiation device 92.
- the inkjet head 88 ejects the ultraviolet curing resin in a thin film on the upper surface of the base 60.
- the ultraviolet curing resin is flattened by the flattening device 90 in the curing section 86 so that the film thickness of the ultraviolet curing resin is uniform.
- the irradiation device 92 irradiates the thin film of ultraviolet curing resin with ultraviolet light. This forms a thin film resin layer 153 on the base 60.
- the inkjet head 88 ejects a thin film of ultraviolet curable resin onto the thin film resin layer 153.
- the thin film of ultraviolet curable resin is then flattened by the flattening device 90, and the irradiation device 92 irradiates the ejected thin film of ultraviolet curable resin with ultraviolet light, thereby laminating a thin film of resin layer 153 on top of the thin film of resin layer 153.
- the ejection of ultraviolet curable resin onto the thin film of resin layer 153 and the irradiation of ultraviolet light are repeated, and multiple resin layers 153 are laminated to form a resin laminate 152.
- the stage 52 is moved below the first modeling unit 22.
- the inkjet head 76 ejects metal ink 160 in lines on the upper surface of the resin laminate 152 according to the circuit pattern, as shown in FIG. 4.
- the infrared irradiation device 78 irradiates infrared rays onto the metal ink 160 ejected according to the circuit pattern. This bakes the metal ink 160, and wiring 162 is formed on the upper surface of the resin laminate 152. Note that in FIG. 4, two wirings 162 are formed, and when distinguishing between the two wirings 162, one of the two wirings 162 is described as wiring 162a and the other is described as wiring 162b.
- the stage 52 is moved below the second modeling unit 23.
- a resin laminate 156 is formed on the resin laminate 152.
- the resin laminate 156 is formed on the resin laminate 152 so as to be continuous with the end of the wiring 162b facing the wiring 162a and the opposite end.
- the part of the resin laminate 156 that is continuous with the wiring 162b is formed as an inclined surface 157.
- the resin laminate 156 is formed by repeatedly discharging ultraviolet curable resin by the inkjet head 88, flattening by the flattening device 90, and irradiating ultraviolet light by the irradiation device 92, in the same way as the resin laminate 152.
- the stage 52 is moved below the first modeling unit 22, and in the first modeling unit 22, as shown in FIG. 6, the wiring 166 is formed on the inclined surface 157 of the resin laminate 156 so as to contact the wiring 162b.
- the wiring 166 is formed by ejecting metal ink from the inkjet head 76 and irradiating infrared rays from the infrared irradiation device 78.
- a resin laminate 168 is formed on the resin laminate 152.
