Also good.

  Next, the electronic component mounting apparatus 10 will be described in more detail with reference to FIGS. 6-1 and 6-2. Since the electronic component mounting apparatus 10a has the same configuration as the electronic component mounting apparatus 10 unless otherwise specified, the description thereof is omitted. FIG. 6A is a perspective view illustrating a schematic configuration of the electronic component mounting apparatus. FIG. 6B is an explanatory diagram of a head included in the electronic component mounting apparatus according to the present embodiment. The electronic component mounting apparatus 10 illustrated in FIG. 6A is an apparatus for mounting electronic components on the collective substrate 108. The electronic component mounting apparatus 10 identifies the position of the circuit board 109 with the position symbol, and mounts the electronic component on each of the plurality of circuit boards 109. As illustrated in FIG. 6A, the electronic component mounting apparatus 10 includes a board conveyance unit 112, a component supply apparatus 114, a head 115, and an XY movement mechanism 116. The electronic component mounting apparatus 10 carries in a collective board 108 which is a set of circuit boards 109 in which position symbols and identification symbols are already associated. However, the electronic component mounting apparatus 10a carries in the collective substrate 108 in which the position symbol and the identification symbol are not associated with each other.

  The substrate transport unit 112 is a transport mechanism that transports the collective substrate 108 in the X-axis direction in the drawing. The substrate transport unit 112 includes a rail that extends in the X-axis direction, and a transport mechanism that supports the collective substrate 108 and moves the collective substrate 108 along the rail. The substrate transport unit 112 transports the collective substrate 108 in the X-axis direction by moving the collective substrate 108 along the rail by the transport mechanism in a direction in which the surface (front surface) of the collective substrate 108 faces the head 115. To do. The board transport unit 112 transports the collective board 108 supplied from a device that supplies the collective board 108 to the electronic component mounting apparatus 10 to a predetermined position on the rail. The head 115 mounts electronic components on the surface of the collective substrate 108 at the predetermined position. When the electronic components are mounted on the collective substrate 108 that has been conveyed to the predetermined position, the substrate conveyer 112 conveys the collective substrate 108 to an apparatus that performs the next step (for example, reflow). Note that various configurations can be used as the transport mechanism of the substrate transport section 112. For example, a rail disposed along the transport direction of the collective substrate 108 and an endless belt rotating along the rail are combined, and the transport mechanism that transports the collective substrate 108 on the endless belt is integrated. A belt-type transport mechanism can be used.

  The component supply device 114 is detachable from the other components of the electronic component mounting apparatus 10, and is supported by the movable support base 125 and the support base 125, and holds many electronic components to be mounted on the collective substrate 108. And a feeder unit 128 that is capable of supplying the electronic components supported by the support base 125 and held by the holding unit 126 to the head 115, that is, a state in which the electronic component can be sucked by the head 115. In the component supply device 114, the holding unit 126 and the feeder unit 128 constitute a single unit, and a large number are arranged in a row on the support base 125. The unit constituted by the holding unit 126 and the feeder unit 128 can be attached to and detached from the support base 125 and can be replaced for each unit. Note that the holding unit 126 and the feeder unit 126 of the component supply device 114 can be replaced with each other. Although various configurations can be used as the configured portion, in the present embodiment, the holding unit 126 in which the electronic component is attached to the tape, the tape is fed by a predetermined amount, and the electronic component is exposed at a predetermined position. It is the tape feeder comprised with the feeder part 128 to make. The component supply device 114 includes a supply control unit 129 as a control function. The supply control unit 129 controls information on electronic components held in the holding unit 126 and supply operations of components in the feeder unit 128. The supply control unit 129 is configured by a memory or the like that stores operations such as a CPU and various types of information. In the present embodiment, the supply control unit 129 is provided in the component supply device 114, but may be provided in the processing unit 28 of the electronic circuit production history management device 2.

  The head 115 is a mechanism that sucks the electronic components held by the component supply device 114 and mounts the sucked electronic components on the collective substrate 108 moved to a predetermined position by the substrate transport unit 112. The head 115 will be described later.

  The XY moving mechanism 116 is a moving mechanism that moves the head 115 in the X-axis direction and the Y-axis direction in FIG. 6A, that is, on a plane parallel to the surface of the collective substrate 108. Part 124. The X-axis drive unit 122 is connected to the head 115 and moves the head 115 in the X-axis direction. The Y-axis drive unit 124 is connected to the head 115 via the X-axis drive unit 122, and moves the head 115 in the Y-axis direction by moving the X-axis drive unit 122 in the Y-axis direction. The XY movement mechanism 116 can move the head 115 to a position facing the collective substrate 108 or a position facing the feeder unit 128 of the component supply device 114 by moving the head 115 in the XY axis direction. The XY moving mechanism 116 adjusts the relative position between the head 115 and the collective substrate 108 by moving the head 115. Thus, the electronic component held by the head 115 can be moved to an arbitrary position on the surface of the collective substrate 108, and the electronic component can be mounted at an arbitrary position on the surface of the collective substrate 108. As the X-axis drive unit 122, various mechanisms that move the head 115 in a predetermined direction (bidirectional) can be used. As the Y-axis drive unit 124, various mechanisms that move the X-axis drive unit 122 in a predetermined direction (bidirectional) can be used. As a mechanism for moving the object in a predetermined direction (bidirectional), for example, a linear motor, a rack and pinion, a conveyance mechanism using a ball screw, a conveyance mechanism using a belt, or the like can be used.

  Next, the head 115 will be described with reference to FIG. FIG. 6B is an explanatory diagram of a head included in the electronic component mounting apparatus according to the present embodiment. The head 115 is driven by the X-axis drive unit 122. The head 115 includes a control board 160, a Z-axis motor 161, a θ motor 162, an air control valve 163, a board recognition camera 164, a barcode reader 167, a laser alignment sensor 165, and a nozzle that sucks electronic components. (Suction nozzle). The control board 160 has a drive circuit for driving the Z-axis motor 161, the air control valve 163, the θ motor 162, and the like.

  The Z-axis motor 161 moves the suction nozzle in the Z-axis direction. With this function, the Z-axis motor 161 moves the suction nozzle closer to the substrate and moves the suction nozzle closer to the substrate away from the substrate. The Z-axis motor 161 mounts the electronic component on the substrate by bringing the suction nozzle that has attracted the electronic component closer to the substrate and bringing the electronic component into contact with the terminal electrode of the substrate. The θ motor 162 rotates the suction nozzle about the Z axis. The Z axis is orthogonal to the XY plane, but the XY plane is parallel to the surface of the substrate on which the electronic component is mounted, so the θ motor 162 rotates the nozzle about an axis orthogonal to the surface of the substrate. . With this function, the θ motor 162 can adjust the positional relationship between the electronic component and the substrate.

  The air control valve 163 switches between suction of the suction nozzle and suction stop. In other words, the air control valve 163 sucks air from the opening of the suction nozzle, thereby sucking the electronic component into the opening of the suction nozzle. Further, the air control valve 163 opens the electronic component sucked by the opening of the suction nozzle from the opening by stopping the suction. The air control valve 163 controls the suction and release of the electronic component by the suction nozzle by causing the suction nozzle to perform such an operation.

  The substrate recognition camera 64 images the recognition marks provided on the suction position reference and the like in addition to the alignment marks 110 (positioning information) provided on the collective substrate 108. By this operation, the substrate recognition camera 164 detects information (position information) about the collective substrate 108 and the position of the stage that holds the collective substrate 108. The board recognition camera 164 detects the position information while electronic parts are mounted on the collective board 108, or detects the position information in teaching of the suction position of the electronic parts and inspection of the mounting position. . The laser alignment sensor 165 has a laser measurement function. With this function, information such as the distance between the head 115 and the collective substrate 108 and the inclination of the head 115 is detected.

  The barcode reader 167 reads the identification symbol from the barcode attached to the circuit board 109 at the position specified by the predetermined position symbol, and uses the read identification symbol as a representative identification symbol of the electronic circuit production history management apparatus 2. It transmits to the communication part 26. The circuit board 109 from which the representative identification symbol is read out may be the circuit board 109 of any position symbol. The circuit board 109 at a certain position symbol position may be read in advance, or the circuit board 109 at a different position symbol position may be read for each collective board 108. The reading position may be designated manually by the operator, or the reading position may be determined by a computer program. In order to shorten the mounting time, it is preferable to read out the identification symbol for the circuit board 109 located closest to the position of the waiting head 115. In any case, the identification symbol of the circuit board 109 at the position specified by one position symbol is read out for each collective substrate 108, and the identification symbol of the read circuit board 109 is used as a representative identification symbol. It is transmitted to the communication unit 26 of the electronic circuit production history management device 2.

  However, the barcode reader 167 of the electronic circuit mounting apparatus 10a is controlled by the processing unit 28 so as to read the identification symbols for all the circuit boards 109 included in the collective board 108. The read identification symbol of the circuit board 109 is transmitted to the communication unit 26 of the electronic circuit production history management apparatus 2.

  For control of the Z-axis motor 161 and θ motor 162 of the head 115, suction of air from the suction nozzle, transmission of information detected by the substrate recognition camera 164, transmission of information read by the barcode reader 167, etc. A flexible cable group 166 in which a flexible cable and a suction tube are bundled is connected to the head 115.

  The display device 22 also functions as a display device that displays information about an image captured by the head 115. The input device 24 functions as a device for inputting an operation for an operator (user) to control the electronic component mounting apparatus 10. The input device 24 sends the input operation to the processing unit 28 as an operation signal. The electronic circuit mounting apparatus 10 may be provided with an input device and a display device.

  The processing unit 28 includes a component information detection unit 28f. The processing unit 28 is held by the feeder unit 128 of the component supply device 114 based on information sent from the supply control unit 129 of the component supply device 114 via the communication unit 26 and an image photographed by the head 115, and the head 115. The electronic component information that can be picked up and mounted on the board is detected. That is, the component information detection unit 28g detects the arrangement configuration of the feeder unit 128 provided in the component supply device 114 and the supply system of electronic components. The position symbol-component identification symbol association unit 28c of the processing unit 28 is a position symbol of the circuit board 109 on which the electronic component is mounted, and information on the mounted electronic component detected by the component information detection unit 28f, that is, component identification. Associate a symbol. The above is the configuration of the electronic component management system 1 and the electronic circuit production history management apparatus 2.

  Next, the operation of the electronic circuit production history management system 1 will be described. FIG. 7 is an explanatory diagram for explaining operations performed in the electronic circuit production history management system 1. FIG. 8 is a flowchart of an electronic circuit production history management method using the electronic circuit production history management system 1. Please refer to FIG. 2 as appropriate.

  First, the identification symbol-position symbol association data creation unit 28a of the processing unit 28 creates identification symbol-position symbol association data (step S1 in FIG. 8). This is, for example, data as indicated by D1 in FIG. However, if the identification symbol-position symbol association data is stored in the identification symbol-position symbol association data storage unit 30b, step S1 and step S2 are omitted and the process starts from step S3.

  Next, the identification symbol-position symbol association data storage unit 30a of the storage unit 30 stores the identification symbol-position symbol association data (FIG. 8, step S2).

  Next, the identification symbol association unit 28b of the processing unit 28 associates the identification symbols of the plurality of circuit boards 108 included in the same collective substrate 109 to form identification symbol association data (FIG. 8, step S3). Then, the identification symbol association data storage unit 30b of the storage unit 30 stores the identification symbol association data. This data is, for example, a data set as indicated by D2 in FIG.

  Next, the electronic component mounting apparatus 10 carries in the collective substrate 108 and arranges the collective substrate at a predetermined position (FIG. 8, step S4).

  Next, the electronic component mounting apparatus 10, specifically, the barcode reader 167 mounted on the head 115, identifies the circuit board 109 located at one location on the collective board 108 and specified by a predetermined position symbol. The identification symbol is read as a representative identification symbol. (FIG. 8, step S5).

  Next, the representative identification symbol storage unit 30d of the storage unit 30 stores the read representative identification symbol (FIG. 8, step S6). The representative identification symbol storage unit 30d preferably stores the read position symbol of the circuit board 108 and the representative identification symbol as a set. This is, for example, data as indicated by D3 in FIG.

  Next, the electronic component mounting apparatus 10 mounts the electronic component identified by the component identification symbol on the circuit board 109 (FIG. 8, step S7). Specifically, the processing unit 28 sequentially designates position symbols in the electronic component mounting apparatus 10 and causes the circuit board 108 identified by the designated position symbols to mount (mount) the electronic components identified by the component identification symbols. . Then, the component information detection unit 28g of the processing unit 28 identifies the electronic components mounted on the circuit board 108 such as the type, lot number, and mounting status of the electronic components from the component supply device 114 of the electronic component mounting apparatus 10. To obtain a component identification symbol.

  Next, the position symbol-component identification symbol association unit 28c of the processing unit 28 is mounted on the circuit board 109 at the position specified by the position symbol acquired by the position information of the circuit board 109 and the component information detection unit 28g. The position identification / component identification symbol association data is obtained by associating the electronic component with the component identification symbol (FIG. 8, step S8).

  Next, the position symbol-part identification symbol association data storage unit 30c of the storage unit 30 stores the position symbol-part identification symbol association data (FIG. 8, step S9). This is, for example, data as indicated by D4 in FIG.

  Next, the processing unit 28 determines whether all the electronic components to be mounted are mounted on all the circuit boards 109 included in the collective substrate 108 (FIG. 8, step 10). If it is determined that all the electronic components are not mounted on all the circuit boards 109 (step S10, NO), the process returns to step S7, and the process of mounting the electronic components on the circuit board 108 is performed again.

  When it is determined that all the electronic components are mounted on all the circuit boards 109 (step S10, YES), the representative identification symbol collating unit 28d of the processing unit 28 associates the read representative identification symbol with the identification symbol. It collates with the set of data (FIG. 8, step S11). This corresponds to collating the data set D2 and the data D3 in FIG.

  Next, the identification symbol association data extraction unit 28e of the processing unit 28 extracts identification symbol association data including the read representative identification symbol from the set of identification symbol association data (step S12 in FIG. 8). This corresponds to extracting identification symbol association data (C001, C002, C003, C004) including the representative identification symbol C001 from the data set D2 in FIG.

  Next, the identification symbol-component identification symbol association unit 28f of the processing unit 28 determines the identification symbol and the component from the extracted identification symbol association data, the position symbol-component identification symbol association data, and the identification symbol-position symbol association data. Association with the identification symbol is performed (FIG. 8, step S13). This corresponds to obtaining data as indicated by D5 from the extracted identification symbol association data (C001, C002, C003, C004), data D1, and data D4 in FIG.

  Next, the identification symbol-part identification symbol association data storage unit 30e in the storage unit 30 stores the set of the associated identification symbol and the component identification symbol as identification symbol-part identification symbol association data (FIG. 8, step S14). ). The above is the electronic component production history management method by the electronic circuit production history management system 1.

  A computer program that realizes these procedures is stored in the storage unit 30, and is read out and processed by the processing unit 28, thereby realizing the electronic component production history management method of the present embodiment. Alternatively, the computer program for realizing these procedures is recorded on a computer-readable recording medium, and is read by the processing unit 28, whereby the electronic component production history management method of this embodiment can be realized.

  Since the electronic circuit production history management system 1 is configured as described above, the electronic circuit mounting apparatus 10 does not need to read the identification symbols for all circuit boards 109. Therefore, the time required for mounting (tact time) is shortened as compared with an electronic circuit mounting apparatus that is controlled to read the identification symbols for all circuit boards 109.

  Next, the procedure for creating identification symbol-position symbol association data (FIG. 8, step 1) will be described in more detail. FIG. 9 is a flowchart illustrating a procedure for creating identification symbol-position symbol association data. First, for example, the assembly board is carried into the electronic component mounting apparatus 10a in the electronic circuit production history management system 1a and the identification symbol assigning apparatus 13 in the electronic circuit production history management system 1b (step S101). Next, the processing unit 28 designates a position symbol of the circuit board 108 to be operated by the electronic component mounting apparatus 10a or the identification symbol assigning apparatus 13 (step S102). In the case of the electronic component mounting apparatus 10a, the work is reading of the identification symbol by the bar code reader 167, and in the case of the identification symbol applying apparatus 13, the operation is assignment of the identification symbol. Next, the electronic component mounting apparatus 10a or the identification symbol assigning apparatus 13 performs an operation on the circuit board 109 with the designated position symbol (step S103). Next, the processing unit 28 causes the electronic component mounting apparatus 10a or the identification symbol assigning device 13 as the input device 24 to transmit the identification symbol, and the processing unit 28 acquires the identification symbol of the designated position symbol (step S104). . A set of the specified position symbol and the acquired identification symbol is stored in the storage unit 30 as identification symbol-position symbol association data (step S105).

  Next, the processing unit 28 determines whether or not all position symbols of the carried-in collective substrate are designated (step S106). If all the position symbols have not been specified yet (step S106, NO), the process returns to step S102. When all the position symbols have been specified (step S106, YES), the collective board is unloaded (step S107). Next, the processing unit 28 determines whether or not all the collective boards have been worked (step S108). If it is determined that the operation is not performed on all the collective substrates (step S108, NO), the process returns to step S101, and the operation is performed on a new collective substrate. If it is determined that the operation is performed for all the collective boards (step S108, YES), the identification symbol-position symbol association data is accumulated for all the circuit boards of all the collective substrates. The association data creation procedure (step S1) ends.

  Since the electronic circuit production history management systems 1a and 1b are configured as described above, it is not necessary for the operator to manually input the circuit board position symbol and the identification symbol in association with each other. Can be performed automatically. In this embodiment, the barcode reader 167 reads, for example, a barcode as an identification symbol, but the substrate recognition camera 164 may read the identification symbol.

(Embodiment 2)
In the second embodiment, the identification symbol provided on the board includes information relating to a production program for mounting and producing electronic components on the board, and the board described above is a collective board having a plurality of circuit boards. Is characterized in that information relating to the production program for each circuit board is included in the identification symbol provided in the circuit board. The second embodiment can be realized by the electronic circuit production management system 1, 1a, 1b, 1c described in the first embodiment.

  FIG. 10 is a diagram illustrating a substrate before electronic components are mounted. FIG. 11 is a diagram illustrating the substrate after the electronic component is mounted. In the present embodiment, an example in which a plurality of electronic components having component identification symbols A to H as shown in FIG. 11 are mounted on one substrate 108a shown in FIG. Unlike the collective substrate 108 of Embodiment 1 (see FIGS. 3 and 4), the single substrate 108a corresponds to the circuit substrate 109 of the collective substrate 108.

  In the present embodiment, the identification symbol C010 has more information than, for example, the barcode (one-dimensional barcode) used as the identification symbol in the first embodiment. For example, a two-dimensional barcode can be used as the identification symbol C010. The substrate 108a is provided with a two-dimensional barcode 113 as an identification symbol C101 at a position adjacent to the alignment mark 110 as positioning information. In the present embodiment, the identification symbol C101, that is, the two-dimensional barcode 113 is an information holding unit having information (hereinafter referred to as production program information) PG010 related to a production program for producing the substrate 108a. The production program information PG010 is stored in, for example, a storage unit such as the electronic component mounting apparatus 10 or 10a illustrated in FIG. 1, FIG. 6-1, FIG.

  The production program information PG005 is, for example, an address of a production program for producing the board 108a, more specifically, a storage device such as the electronic component mounting apparatus 10 in which the production program is stored, or the electronic circuit production shown in FIG. This is information indicating an address in the production program storage unit 30f of the history management device 2. When the electronic component mounting apparatus 10 or the like that has acquired the production program information PG005 produces the board 108a, the production program information PG005 accesses the address at which the production program for producing the board 108a is stored from the production program information PG005. Is read. Then, the electronic component mounting apparatus 10 or the like mounts electronic components on the board 108a according to the read production program and produces them. Next, an electronic circuit production method according to the second embodiment will be described.

  FIG. 12 is a flowchart of an electronic circuit production method using the electronic circuit production history management system. Next, the electronic circuit production history management system 1a and the electronic component mounting apparatus 10a shown in FIG. 5A execute this electronic circuit production method. First, the electronic component mounting apparatus 10a as the input device 24 acquires the identification symbol C010 of the board 108a that has been carried in by the barcode reader 167 shown in FIG. 6 (step S201). When the identification symbol C010 can be acquired (step S202, Yes), the process proceeds to step S203. In step S203, when the electronic component mounting apparatus 10a includes production program information in the acquired identification symbol C010 (step S203, Yes), the production program for producing the board 108a that has been carried in based on the production program information. Access and read this. (Step S204). Then, the electronic component mounting apparatus 10a mounts the electronic component on the substrate 108a to produce the substrate 108a (step S205).

  When the identification symbol C010 cannot be acquired in step S202 (step S202, No), or when the production program information is not included in the identification symbol C010 acquired in step S203 (step S203, No), the electronic component mounting apparatus 10a. Is temporarily recognized as a recognition error of the identification symbol C010 by the barcode reader 167 (step S206). Next, when the production of the board 108a is continued (step S207, Yes), the operator of the electronic component mounting apparatus 10a teaches the electronic component mounting apparatus 10a an operation in which the barcode reader 167 reads the identification symbol C010. Alternatively, the identification symbol C010 is input to the electronic component mounting apparatus 10a. At this time, the operator may input the identification symbol C010 to the electronic component mounting apparatus 10a via a portable barcode reader different from the barcode reader 167 included in the electronic component mounting apparatus 10a. When the identification symbol C010 is recognized by the electronic component mounting apparatus 10a, the electronic component mounting apparatus 10a executes Step S204 and Step S205. When the production of the substrate 108a is not continued (No at Step S207), the production of the substrate 108a is finished.

  The electronic component mounting apparatus 10a associates the identification symbol C010 with the electronic component mounted on the board 108a, creates identification symbol-component identification symbol association data, and transmits it to the electronic circuit production history management device 2 shown in FIG. May be. The identification symbol-component identification symbol association data storage unit 30e of the storage unit 30 of the electronic circuit production history management device 2 stores identification symbol-component identification symbol association data transmitted from the electronic component mounting apparatus 10a. In this way, the production history of the electronic circuit can be managed. Next, a case where a collective board having a plurality of circuit boards is produced will be described.

  FIG. 13 is a diagram illustrating a collective substrate before electronic components are mounted. FIG. 14 is a diagram illustrating the collective substrate after the electronic components are mounted. FIG. 15 is a flowchart of an electronic circuit production method using the electronic circuit production history management system. In this example, when one collective board 108b shown in FIG. 13 has four circuit boards 109, as shown in FIG. 14, a plurality of electronic parts having part identification symbols A to H on each circuit board 109 are shown. An example of implementing is described.

  In the present embodiment, the two-dimensional barcode 113b that also functions as an identification symbol is an information holding unit that includes production program information PG021 to PG024 relating to a production program for producing each circuit board 109 included in the collective board 108b. . The collective substrate 108b is provided with a two-dimensional barcode 113b as an identification symbol at a position adjacent to the alignment mark 110 as positioning information.

  The production program information PG021 to PG024 is, for example, a storage device such as the electronic component mounting apparatus 10 in which a production program for producing the circuit board 109 is stored, or a production program storage of the electronic circuit production history management device 2 shown in FIG. This is information indicating an address in the part 30f. When the electronic component mounting apparatus 10 or the like that has acquired the production program information PG021 to PG024 produces the circuit board 109, the production program for producing the circuit board 109 from the production program information PG021 to PG024 is stored at an address. Access and read this production program. The electronic component mounting apparatus 10 and the like mount electronic components on the circuit board 109 according to the read production program and produce them.

  When the electronic circuit production history management system 1a and the electronic component mounting apparatus 10a shown in FIG. 5A produce the circuit board 109, the electronic component mounting apparatus 10a serving as the input device 24 is two-dimensional of the collective board 108b that has been carried in. The identification symbol of each circuit board 109 is acquired from the barcode 113b by the barcode reader 167 shown in FIG. 6 (step S301). In the present embodiment, the two-dimensional barcode 113b includes production program information PG021 to PG024.

  When the production program information PG021 to PG024 can be acquired as identification symbols (step S302, Yes), the process proceeds to step S303. In step S303, the electronic component mounting apparatus 10a determines that all the circuit boards 109 and the obtained production program information PG021 to PG024 exist for all the circuit boards 109 (Yes in step S303), based on the production program information. A production program for producing one of the circuit boards 109 of the collective board 108b that has been loaded is accessed and read. (Step S304). Then, the electronic component mounting apparatus 10a mounts the electronic component on the target circuit board 109 to produce one circuit board 109 (step S305).

  In step S306, if there is a circuit board on which no electronic component is mounted (step S306, Yes), the electronic component mounting apparatus 10a repeats steps S304 to S306. When there is no circuit board on which no electronic component is mounted (No in step S306), the production of all circuit boards 109 included in the collective board 108b is finished.

  When the production program information PG021 to PG024 cannot be acquired in step S302 (step S302, No), or the production program information PG021 to PG024 of all the circuit boards 109 are not included in step S303 (step S303, No).

Further, in the present embodiment, for example, a device that reads the identification symbol C010 provided for each electronic component mounting apparatus 10a reads the identification symbol C010, thereby determining a production program for producing the board 108a. As a result, it is not necessary to associate the production program with an identification symbol (for example, a barcode), which has been necessary in the on-demand production, that is, the setup work in which the production program is switched. Also, the production program information PG021 to PG024 of the circuit board 109 is included in the two-dimensional barcode 113b as an identification symbol for all the circuit boards 109, so that all the circuit boards 109 are obtained from one two-dimensional barcode 113b. The production program information PG021 to PG024 can be read. As a result, the number of times or time for recognizing the production program information PG021 to PG024 can be shortened. Further, identification symbols (for example, two-dimensional barcodes 113 and 113b) provided on the substrate 108 or the collective substrate 108b can be minimized. In the present embodiment, the collective board 108b only needs to have a smaller number of identification symbols than the number of the plurality of circuit boards 109, that is, the two-dimensional barcode 113b.

In step S403, when the electronic component mounting apparatus 10a includes all the circuit boards 109 and the acquired identification symbols C021 to C024 and production program information PG021 to PG024 exist for all the circuit boards 109 (Yes in step S403), Based on the production program information, a production program for producing one of the circuit boards 109 of the collective board 108b that has been loaded is accessed and read. (Step S404). Then, the electronic component mounting apparatus 10a mounts the electronic component on the target circuit board 109 to produce one circuit board 109 (step S405).
