Description

In the present invention, when an electronic component is mainly mounted on a substrate by a mounting machine to create an electronic circuit board, an electronic component meeting various needs can be easily selected by a search operation using a display screen. The present invention relates to a mounting data creation method and apparatus for creating mounting data for mounting a selected electronic component automatically by a mounting machine without manually inputting data related to a mounting target component.

  There are various types of electronic components mounted on a board for producing various types of electronic circuit boards, and there are different kinds of parts that can be substituted. The number of parts from other companies that can be interchanged increases further. In order to create an electronic circuit board by mounting various electronic components on a substrate, it is necessary to select an electronic component that meets various needs set in the design of the electronic circuit. In mounting various types of electronic components on a substrate, it is necessary to consider that the characteristics and durability of the electronic components to be mounted and other electronic components are not affected, and that mounting is achieved properly and reliably. In recent years, with the minimization of lead pitch due to the higher density of components, the need to correctly recognize the shape of the component and mount it with high accuracy is increasing.

  The specific conditions to be considered are the types of nozzles and chucks that carry electronic components, the moving speed of the mounting head that has the nozzles and chucks, the time when electronic components are taken out from the component supply unit, and when mounting components. Necessary lowering position of the nozzle and chuck, that is, the height position when removing the component, the height position when mounting the component on the substrate, the moving speed of the substrate on which even one electronic component is mounted, especially acceleration, and There are various tolerance values.

  Various electronic components are taped to be automatically supplied to the mounting machine, accommodated in a tray, or handled as sticks or bulk components, including such component supply form and component storage pitch in that case. In addition, it is necessary to consider the so-called packaging when creating mounting data.

  On the other hand, at the stage of mounting the electronic component, recognition of the suitability and orientation of the electronic component, and replacement of an erroneous component and correction of the orientation based on the result are performed. For such inspections, inspection data is also created as mounting data from information on electronic components such as the shape and surface reflectance of electronic components, colors, colors, polarity marks, printed characters and color codes on components, etc. There is a need to.

  In order to select various electronic components according to the circuit design needs, and to create mounting data and inspection data for properly mounting the selected electronic components, each electronic component is detailed and complicated. Parts catalog books have been used in which various parts information is edited and recorded according to a predetermined classification. Depending on the part, in order to obtain necessary data, the electronic part is actually measured with a caliper or the like.

  Of course, it is difficult to search for electronic parts that meet your needs from the parts catalog book, and the optimum selection of required parts depends on how carefully you use the parts catalog book for parts selection. And spend a lot of effort and time. In particular, recently, the needs are diversified and the types of electronic components to be provided have become enormous, so the amount of information has further increased, making it more difficult to optimally select electronic components.

  In order to solve this problem, a so-called electronic component catalog has been provided in which electronic component catalog information is handled as image data for screen display and edited and stored in accordance with a predetermined classification. The electronic part image data stored in the electronic parts catalog is read out according to a predetermined classification and search by a dedicated reading device or personal computer, and is displayed on the screen. Search and select parts in a reasonably short time. A storage medium such as a CD-ROM is used for the electronic parts catalog. Image data for displaying various data of various parts on the screen as shown in FIG. It is a component electronic catalog EC or the like having image data file IMF in which data and graphic data relating to pictures, figures, etc. are collected or appropriately divided.

  This electronic component catalog EC stores image data that can be displayed on the screen in the form of photographs, drawings, tables, and graphs of various types of information such as the form, dimensions, surface condition, characteristics, and application range of electronic components. However, it naturally includes information for creating component mounting data.

  The flowchart of FIG. 24 shows a procedure for creating conventional component mounting data using such a component electronic catalog EC. This will be described. The electronic part catalog EC is read out, loaded into the apparatus, and started to be read out on the screen. Next, a command is input by a search key operation and a condition setting operation according to a predetermined classification and search procedure. As a result, the command analysis unit searches and repeats command input until one electronic component is selected.

  FIG. 25 is a display screen obtained by designating a large classification transistor and searching for a small classification Bi-Polish transistor (PNP) 2SA, 2SB. This screen is in a search state in which the cursor is positioned in the first part column among 62 corresponding parts. The user can search for any of the 62 parts by placing the cursor in the required parts column. As a result, one electronic component is selected, and it is possible to determine which component image data is to be displayed on the screen. Various image data regarding the determined component can be determined according to a predetermined procedure and the user's Displayed on the screen according to the operation.

  For example, when a part 2SA1022 is searched for on the screen of FIG. 25 and an explanation key is operated, image data relating to the initial explanation of the part 2SA1022 is displayed on the screen as shown in FIG.

  When search is selected on the screen of FIG. 26, a list of large classification display items that can be selected on the screen of FIG. 26 is displayed in a window as shown in FIG. When the outline drawing is selected by looking at the screen of FIG. 27 or directly from the screen of FIG. 26, image data relating to the outline as shown in FIG. 28 is displayed on the screen. When the land diagram is selected, image data relating to the land as shown in FIG. 29 is displayed on the screen. When the taping dimension is selected, image data related to the taping dimension is displayed on the screen as shown in FIG. When the reel size is selected, image data relating to the reel size is displayed on the screen as shown in FIG.

  FIG. 32 shows a state in which image data relating to the characteristic curve is displayed in a window according to the selection of the characteristic curve on the initial explanation screen when the electronic component of the motor control circuit called AN6650 is searched. FIG. 33 is an initial explanation screen of FIG. 32, in which an application circuit example is preferentially selected and displayed in a window, and further, a block diagram is selected and displayed in a window.

  The user can relatively easily select an electronic component that meets the circuit design needs while searching for the component information, and various pieces of component information necessary for creating mounting data on the selected electronic component to be mounted. Can also be visually recognized by the search operation. In addition, it is possible to freely perform a data search corresponding to a component mounting method using a chuck or a suction nozzle, a presence / absence of component recognition, a difference in a method, and the like.

  In addition, in order to create component mounting data based on data obtained by visual recognition using a component electronic catalog as described above, an automatic data processing device such as a dedicated or personal computer is used for the visual recognition. By manually inputting the mounting data for the component obtained in this way, the component mounting data is generated by performing combination data processing with the mounting position data of the component created in advance.

  The above-described conventional electronic parts catalog can be used to select electronic parts that meet the needs relatively easily by using a programmed rational search system, and to efficiently and sequentially view various data. . However, since all recorded data is image data for screen display, it cannot be used as data for automatically creating mounting data for mounting each selected electronic component. For this reason, the user needs to manually input the visual data obtained for each of the necessary electronic components sequentially by the search, as described above, to the automatic data processing device. Even with the electronic component catalog, it takes a lot of labor and time to create component mounting data.

An object of the present invention is to solve such a problem, and in addition to searching for a part screen as a parts electronic catalog similar to the conventional one, mounting data on a mounting target part selected by this search or the like is automatically obtained. The main purpose is to provide a method for creating mounting data that automatically reads component text data and automatically creates component mounting data without manual input of component data. It is.

The present invention is a mounting data creation method for receiving mounting of a mounting target component and generating mounting data for the mounting machine to mount at the mounting position, image data about the outer shape of various components including the mounting target component, and Both parts text data necessary for mounting parts such as shapes and dimensions of various parts are stored in the parts electronic catalog for each part type, and based on the mounting position data including the mounting position for the mounting target part, By reading out the image data and the part text data for each same part from the part electronic catalog , the data reading processing means, and simultaneously displaying the read image data and part text data on the screen for each same part , subjected by the search means to search and selection of various kinds some components, data generation processing means, the real And position data, based on the component text data of the selected component, and wherein the creating the mounting data.

DETAILED DESCRIPTION The method and apparatus for creating implementation data of the present invention will be described while showing some embodiments.

(Embodiment 1)
In the first embodiment, as shown in FIG. 1A, a storage medium 12 that is a CD-ROM is used as a component electronic catalog, and various electronic devices are used by using a data processing device 3 different from the mounting machine 4. It is possible to search for parts and automatically create mounting data for each mounting target part selected by this search. The data processing device 3 has data reading processing means 1 and data creation processing means 2 as shown in FIG. The data processing apparatus 3 is preferably a personal computer, but is not limited thereto, and may be a dedicated machine. In some cases, a data processing device on the mounting machine 4 side or a control system for operation control can be used.

  The mounting machine 4 is equipped with a necessary number of component supply cassettes 5 equipped with taping components, receives supply of necessary electronic components from these component supply cassettes 5 each time, recognizes whether each component is correct, If it is not correct, the electronic component is automatically mounted on the substrate with high accuracy by taking a measure called correction. For this automatic mounting, a data processing device 8 is provided separately from the control system 7 for operation control. This data processing device 8 has a display 9, and includes an NC program which is mounting position data for each mounting target component, a supply library related to a component supply state such as an arrangement of components in a component supply unit, and predetermined components to be supplied. Based on a component library or the like for accurately and reliably recognizing and mounting on the position, an actual component supply and an operation control program for mounting the supplied component at a predetermined position are created and used in the control system 7 Control data. The mounting data C need only be created according to the individuality of the mounting machine 4 such as the function level of the mounting machine 4 and the supply form of components, and the specific contents can be freely set.

  The data reading processing means 1 is stored in advance as a component electronic catalog, together with image data IM, for various components including the mounting target component based on the position data A as shown in FIG. 2 regarding the mounting position generated for the mounting target component. From the part text data B as shown in FIG. 3 required for the mounting of the parts such as the shape, dimensions, packaging, and color of the parts stored in the medium 12, the part text data b for each mounting target part at each mounting position. Is read by automatic data processing. The data creation processing unit 2 performs automatic data processing between the mounting position data A and data including component text data b for each mounting target component at each mounting position read by the data reading processing unit 1. Receives supply of each component and creates mounting data C for mounting them on a predetermined mounting position of the board.

  The mounting data C includes, for example, an NC program as shown in FIGS. 4 to 7, a component library, an arrangement program as a supply library, and a component supply position library related to the condition of the component take-out position at the time of component supply by a tray It is.

  The mounting position data A can be created by, for example, the CAD device 11, and may be input to the data processing device 3 every time the mounting position data is created, or a list of all the mounting position data created is stored. This may be transferred to the data processing device 3, or a storage medium storing the mounting position data C may be loaded into the data processing device 3 for use. The storage medium 12 for providing the part text data B is necessary for mounting the image data IM for various parts including the parts to be mounted as shown in FIG. 8 and the parts such as the shape, size, package, and color of each part. The part text data B is edited and stored according to a predetermined classification. Therefore, the image data IM and the component text data B are used in combination, and various types of information about various electronic components are displayed on the screen according to a predetermined procedure and search, and can be used as a conventional component electronic catalog. An interface for this purpose may be provided either on the storage medium 12 side or on the data processing device 3 side. In addition, it is possible to perform necessary screen display for various electronic components using only the image data IM.

  The storage medium 12 includes a CD-ROM, a flexible disk, an optical disk, and the like, but any storage medium or storage device may be used. For post-processing such as addition, deletion, correction, and correction of data, data that can be read and written is preferable. Writing can be done using an appropriate device such as a dedicated machine or a general-purpose machine such as a personal computer, but data addition, deletion, correction, correction, etc. are automatically performed according to the mounting history of the mounting machine 4 Can also be done.

  As described above, according to the first embodiment, the storage medium 12 includes image data IM for various components including the mounted components, and component text data necessary for mounting the components such as the shape, size, package, and color of the components. In addition to the conventional screen search as a component electronic catalog using the component electronic catalog that also stores B, the mounting target component information of the mounting position data A created in advance for each mounting target component is also stored. In addition, a corresponding one of the component text data B stored together with the image data IM in the storage medium 12 is automatically read out to obtain component text data b for each mounting target component at each mounting position. In conventional automatic data processing using this mounting position data A and data including component text data b for each mounting target component at each mounting position For example, an NC program related to the mounting position of components required by the conventional mounting machine 4, a component library related to recognition of electronic components such as the shape, size, and color of components, and an arrangement of components in a component supply unit Necessary mounting data C called a supply library relating to the supply state of the components can be created, and mounting data C for supplying each component to the conventional mounting machine 4 and mounting them at a predetermined mounting position is generated. Can be created by automatic data processing.

  Therefore, since it is not necessary for a person to input various component data necessary for creating the mounting data C for each mounting target component, the labor and time required for creating the mounting data can be greatly reduced.

  However, depending on the model and control level of the mounting machine 4, mounting data C corresponding to it is created. Further, if the mounting data C is created in consideration of the characteristic data of the mounting machine 4, the mounting data C that matches the characteristics of the mounting machine 4 can be generated. More appropriate parts can be mounted, which means that there will be no unreasonableness or failure. The mounting data C can include inspection data for accurate component mounting. This is to determine whether the part itself and the orientation of the part held by the nozzle or chuck are appropriate, and if it is an incorrect part, replace it and mount it properly. The inspection data to be performed is generated by the component text data b obtained for each component, and the inspection data appropriate for the component to be mounted is automatically obtained. Appropriate inspection can be performed and accurate component mounting can be guaranteed.

  The storage medium 12 according to the first embodiment stores both the part text data B and the image data IM corresponding to various parts as described above. Therefore, the data reading processing means 1 reads both the image data IM and the part text data B for each part stored in the storage medium 12 for each same part according to a predetermined search operation, and the video signal D To the display 13 of the data processing device 3 so that it can be displayed on the same screen. At the same time, the part text data can be output to other parts by an output operation.

  Accordingly, in the search operation, the same parts of the image data IM and the part text data B for each part stored in the storage medium 12 are displayed on the same screen of the display 13 to search for various types of parts. Since the part text data B can be output to others as required, it can be used for various data processing.

  Further, as described above, when the data is outside the apparatus like the storage medium 12 storing the image data IM and the part text data B, the input of various data is performed by the data processing apparatus 3 which is a mounting data creating apparatus. It can be performed remotely and independently, and data can be easily changed and added. Moreover, it can be shared by various mounting machines 4.

  If the storage medium 12 storing the component text data B is used to transmit information by communication, one storage medium 12 is used without limitation on the installation location of the mounting machine 4 and is shared by many mounting machines 4. There is an advantage that it is possible to create, manage, change, and add part text data B. The communication is not particularly limited to communication methods such as wired, wireless, telephone line, and optical communication.

  Further, the data processing program executed by the data processing device 3 can be stored in an external CD-ROM 15 as shown in FIG. 9 or other appropriate storage medium. For example, as described above, the storage contents of this program include various components including the mounting target component based on the mounting position data A regarding the mounting position including the mounting angle created by controlling the data reading processing unit 1 and mounting the component. Mounting of each mounting position from component text data B necessary for mounting the component, such as the shape, dimensions, package, and color of the component, which is created in advance together with the image data IM and stored in the storage means such as the storage medium 12 Data reading program file 15a related to data reading program that reads component text data b corresponding to the target component and data creation processing means 2 to control mounting position data A and data reading related to each mounting target component Data including component text data b for each electronic component read by the processing unit 1 Al, mounter 4 is a data creation processing program file 15b a program for creating mounting data C for mounting a predetermined mounting position them supplied with the electronic components. However, the present invention is not limited to this, and a specific storage form can be freely selected.

  In this way, various programs can be input independently from the data processing device 3 that is the mounting data creation device, and programs can be easily changed or added. Moreover, it can be shared by the same kind of mounting machines 4.

  The creation of the mounting data C will be described more specifically. The representative example of the NC program indicating the component mounting position, the component library for recognizing various electronic components, and the various electronic components in the component supply unit. This is a supply library related to the supply of parts, such as the arrangement of parts and the conditions such as the position of picking up parts in the case of a part supply type using a tray. In the case of a component supply apparatus that operates to supply a selected component to the mounting machine 4 while mounting a large number of component supply cassettes and moving them in the direction of the feed axis as the supply library, instruction data on the mounting position of the component supply cassette There will be other necessary data. FIG. 10 is an operation screen of the display 13 in a mode for generating a part library. The search for the electronic component corresponding to each component mounting position of the component position data A is performed by the start key 16 and the cancel key 17, and the component corresponding to the component library generation model set by another start key 18 and the cancel key 19 is used. The library 20 or the like is automatically generated based on the component text data b read from the component text data B corresponding to each searched electronic component and the component position data A.

  Other items to consider regarding component mounting include the types of nozzles and chucks that carry electronic components, the moving speed of mounting heads that have nozzles and chucks, the required lowering positions of nozzles and chucks when mounting electronic components, That is, there are a mounting height on the board, a moving speed of the board on which the electronic component is mounted, particularly acceleration, and various allowable values. In addition, these various electronic components are handled, for example, by being taped or accommodated in a tray for automatic supply to a mounting machine, including such a component supply form and component storage pitch in that case, It is necessary to consider so-called packing conditions. Such data can also be automatically created as a supply library or other mounting data C.

  In addition, at the stage of mounting the electronic component, recognition of the suitability and orientation of the electronic component, and replacement of an erroneous component and correction of the orientation based on the result are performed. For such inspection, component text data B relating to other recognition of the electronic component such as the shape, surface reflectance, color, color, polarity mark, printed character and color code of the component is also required. Yes, necessary inspection data can be automatically created as mounting data C by using such component text data B.

  In some cases, the inspection data of the product substrate after the mounting of the electronic component can be automatically generated.

  If the component text data B includes data such as the package material, surface roughness, surface shape code, component shape dimensions, and component weight of the electronic component, it is best to pick up the electronic component with a nozzle. Or mounting data C that is optimally held by the chuck, the moving speed of the component mounting head equipped with the nozzle or chuck, the suction force, the moving speed of the substrate after the electronic component is mounted, especially acceleration, Mounting data C such as various allowable values, tape and tray supply form, tape and tray packaging, especially with and without cover and push-up pins, tape and tray component storage pitch, and further storage with tray If the mounting data C includes the number of rows and the pitch between rows, etc., it depends on the presence or absence of the cover peeling operation, the presence or absence of the push-up pin, and the difference in the parts feed pitch. Out once for one pitch feed can be set once stamped and say the mounting condition of 2 pitch feed.

  Next, in the screen of FIG. 15 by the operation of step # 3, the following is selected in accordance with the purpose of selecting the component that meets the needs or obtaining the component data for creating the mounting position data A relating to the selected component. Select the screen displayed on the screen. For example, an outline drawing, a recommended land, a tape shape, or the like is selected. This completes the operation of step # 4.

  For selection of the outline drawing by the operation of step # 4, image data IM corresponding to the outline of the selected electronic component and component text data B corresponding to the dimension of the selected electronic component are stored in step # 5. Are read from the storage medium 12 and synthesized, and a screen display as shown in FIG. 16 is performed in step # 6. On this screen, the outline drawing E including the dimension lines of the electronic component and the part text data F having dimensions corresponding to the dimension lines are simultaneously displayed on the screen. When the size output is selected on this display screen, the part text data B can be output elsewhere.

  For the selection of the land map by the operation of step # 4, the image data IM corresponding to the land shape of the selected electronic component and the component text data B corresponding to the land size of the selected electronic component are stepped. In step # 5, the data is read from the storage medium 12 and synthesized. In step # 6, a screen as shown in FIG. 17 is displayed. On this screen, an outline drawing G including land dimension lines and component text data H having dimensions corresponding to the respective dimension lines are simultaneously displayed on the screen. When the size output is selected on this display screen, the part text data H is input elsewhere.

  For the selection of the taping dimension by the operation of step # 4, the image data IM corresponding to the taping shape of the selected electronic component and the part text data B relating to the taping dimension of the selected electronic part are stored in the storage medium. 12 is read and synthesized, and a screen display as shown in FIG. 18 is performed in step # 6. On this screen, the form I with taping dimension lines and the part text data J having dimensions corresponding to the dimension lines are displayed.

  When the mounting position data A is created by a CAD device or the like, the mounting position data A and the component text data B stored in the storage medium 12 are used to convert various mounting data C shown in step # 7 into the data processing device 3. Can be generated automatically.

  When the reel dimensions are selected on the screen of FIG. 15, the reel image data IM and the component text data B relating to the selected electronic component are read from the storage medium 12 and synthesized, and a screen display as shown in FIG. 19 is performed. On this screen, the drawing K of the reel and the part text data L corresponding to the dimension line are displayed.

  Further, as the mounting of the electronic components according to the generated mounting data proceeds in the mounting machine 4, electronic components that require maintenance or electronic components that have become obsolete may be generated. Sometimes you want to use alternative parts. You may also want to use compatible electronic parts from other companies if your company does not have replacement parts.

  Accordingly, it is also desirable to store and manage data of replacement parts for parts for maintenance and waste products, and further, parts compatible with other companies that are desired to be used without replacement parts.

  In the first embodiment, the target data for such maintenance, waste parts and substitute parts, and target data for parts compatible with other companies are also stored as part text data B of the parts. As shown in FIG. 21, it is possible to search while displaying the screen.

  If the part text data B includes part shape, electric capacity, characteristics, mounting machine characteristics, plane graph, alternative parts, other company compatible parts, and part cost data, the mounting data C is shown in FIG. As shown in the flowchart, the component shape data, electric capacity, and characteristics automatically determine the adjacent insulation and the necessary insulation distance to see if there is interference between components when placing electronic components on the board, It is possible to set a necessary minimum arrangement interval and automatically set an optimum recommended land shape for the electronic component.

  In addition, by handling mounting machine characteristics and plane graph data, it is possible to perform a grouping process for determining mounting order and arrangement so that various electronic components to be mounted can be mounted faster.

  Furthermore, by including alternative parts, other company compatible parts, and cost data, it is possible to perform data processing so as to select and mount a part with the lowest cost. In addition, if an alternative part or another company's compatible part is different in shape and color from the original electronic part, it will be recognized as an erroneous part and error processing will occur at the stage of mounting the part, so an inspection program will be created along with the mounting data creation However, the process of rewriting the inspection data can be automatically performed.

  In addition, if the part text data B includes a code indicating a shape characteristic such as a protruding state of a connection bump on the lower surface of the part, the mounting height of the cage for mounting the part on the board by the mounting data creation program In addition, a process for determining the pushing amount or the pushing pressure can be automatically performed.

  Also, as the numerical data B of the part, the shape and size of the part, color and color, reflectance, presence and state of lead and cut lead, polarity mark, printed characters such as 1005CR, 10Ω on the part, color code, When the surface roughness and the surface material are included, it is possible to automatically perform a process of determining whether the component recognition method employed when mounting the component is a reflection method or a transmission method, depending on the shape and size of the component. Specifically, large parts are clearly visible even in the transmission method, and are easily recognized correctly. However, if they are small components, the shadow of the nozzle is reflected and only the outer shape can be recognized, so the transmission method is not suitable. Also, small parts can recognize not only the outer shape but also the leads on the lower surface when recognized by the reflection method, and even if mounted using a nozzle with a large diameter, this does not interfere with the recognition. is there. Therefore, it is possible to determine that a large electronic component is a transmission method and a small electronic component is a reflection method so that there is no erroneous inspection.

  In addition, processing for changing the amount and type of illumination light for recognizing a component can be automatically performed according to color, color and reflectance, surface roughness, and surface material. Specifically, since the mirror surface has high luminance, the reflected light cannot be recognized with strong light, and when the surface is dark, it cannot be recognized with weak light. Depending on each surface condition, the optimum light type and light amount are changed.

  Furthermore, processing for confirming and correcting the mounting direction of the component is performed according to the presence / absence and state of the lead and lead cut, and the polarity mark. In addition, it is possible to automatically perform a process for checking mounting parts from printed characters and color codes on the parts and preventing mounting of erroneous parts.

  In addition, if the part text data B includes a plurality of packing form data that can be adopted for the same kind of parts, the packing form data that can be adopted for the same kind part in the operation of creating the mounting data, for example, taping, tray, and stock. Depending on the type and capacity of the component supply mechanism, the processing to determine to adopt the supply format that can be adopted or the supply format that minimizes the mounting tact time is automatically performed based on the multiple data and the mounting machine characteristic data. Can be done automatically.

  In addition, by utilizing the fact that each component supply cassette for each component mounted on the mounting machine has a memory for managing the cassette and the components, this memory has a new size, color, and polarity. Write the supply code such as the shape code, packing form, feed pitch, and supply direction, and determine whether the part and cassette match when setting the part in the cassette. To prevent. At the same time, in the control system of the mounting machine equipped with the component supply cassette, all the information of various electronic components stored in the memory of each component supply cassette is read, and the mounting data given to this control system is created According to the program, component mounting data C including all of the read components can be generated, and components can be mounted using this. This eliminates the need for a special control system or data file.

  If the part text data B includes shape data such as the vertical, horizontal, and height of the part, the volume or weight of the part is calculated from the data, and the nozzle that handles the part based on the obtained volume or weight data. It is also possible to automatically select the chuck and to set the moving speed of the head having the nozzle and the chuck, the table moving speed, particularly the acceleration, and various allowable values.

  In addition, as part text data B, the package color code, the part shape, the recommended land shape of the part, the surface material of the part, the reflectance of the surface (if the reflectance is different for each part such as both ends and the center of the part, Including the reflectance of each part), polarity marks, printed characters and color codes on the component surface, etc., an inspection program for inspecting various components after mounting is automatically generated corresponding to the components in the mounting data Can do.

  Therefore, it is not necessary to select and set electronic components that meet the needs as in the case of mounting data creation. The type of component and the inspection data for each type are obtained by simulating the component mounting data.

  In addition, when the part text data B includes a part shape, in particular, vertical, horizontal and height sizes, and lead information, the lead data in the appearance inspection can be automatically set in the inspection program based on these. .

  In addition, if the component text data B includes the temperature characteristics of all the electronic components mounted on the same board, the component mounting data creation program automatically performs a process for setting the conditions depending on the temperature when mounting the electronic components mounted on the board. Can be done automatically. Specifically, when electronic components are mounted on both sides of the substrate, the first surface to be mounted first is set so that an electronic component having higher heat resistance characteristics than the second surface to be mounted later is mounted.

  Thus, an electronic component having a high heat resistance mounted on the first surface of the substrate is bonded using a reflow solder having a high melting point, and an electronic component having a low heat resistance mounted on the second surface uses a reflow solder having a low melting point. When the electronic component is mounted on the first surface, the electronic component is mounted on the second surface. When the electronic component is mounted on the second surface and reflow soldering is performed, the solder is melted and the mounted electronic component is dropped. It is possible to prevent the electronic component having low heat resistance from being damaged during reflow soldering when mounting the electronic component.

  In addition, if the part text data includes necessity data such as burning or refrigeration depending on whether or not it is a hygroscopic part, it can automatically perform the process of generating the handling conditions of the part together with the mounting data when mounting the part. it can.
