Description

  The present invention relates to a data processing apparatus configured to be able to correct inspection data for specifying a position of a point for probing a probe in an electrical inspection on a multi-sided board formed by arranging a plurality of circuit boards of the same type. It is about.

  As this type of apparatus, a data generation apparatus disclosed by the applicant in Japanese Patent Application Laid-Open No. 2010-107265 is known. This data generation device shows electronic component data including information that can specify the position of the tip of each connection terminal in the electronic component, the position of the electronic component on the circuit board when the electronic component is mounted on the circuit board, and the like. Electronic components are mounted based on mounter data including information and wiring pattern data (CAD data and Gerber data) including information that can specify the position and width (shape) of the wiring pattern and land on the circuit board. When inspecting a circuit board, a point (probing position) for probing the inspection probe is specified and position data is generated. Specifically, in this data generation device, the position of the tip of the connection terminal in the electronic component in the mounted state is specified based on the electronic component data and the mounter data, and the position of the land is specified based on the wiring pattern data. Thus, when it is determined that a land exists at the position of the tip of the connection terminal, the position of the land is specified as a point.

  On the other hand, due to misalignment of the wiring pattern that occurs during the manufacture of the circuit board, misalignment that occurs when the electronic component is mounted on the circuit board, the connection terminals and lands are identified at the points specified based on the above data. It may not exist. For this reason, this type of data generation apparatus is generally provided with a function of correcting the coordinates of a point by performing a correction operation. In this case, the applicant has a function of correcting the coordinates included in the position data generated for the inspection of the multi-sided board formed by arranging a plurality of circuit boards of the same type in the following procedure. A data generator is being developed. In the data generation apparatus that corrects coordinates in the first procedure (first procedure), a predetermined position (reference position) on one circuit board (reference circuit board) in the multi-sided board is used as the origin. An image indicating the positions of all points on the multi-sided board in coordinates (absolute coordinates) is displayed on the display unit. Next, the operation unit is operated to select a coordinate to be corrected from the image, and the coordinate is corrected. Subsequently, the processing unit stores the corrected coordinates in the storage unit. Further, in the data generating apparatus that corrects the coordinates in the second procedure (second procedure), the above-described reference circuit is used by utilizing the fact that the circuit boards in the multi-sided board are formed in the same shape. The position of each point in the board is indicated by coordinates (absolute coordinates) with the above reference position as the origin, and the position of each point in other circuit boards excluding the reference circuit board is the corresponding position corresponding to the reference position Are displayed on the display unit in coordinates (relative coordinates) expressed by the same values as the absolute coordinates. Next, the operation unit is operated to select a coordinate to be corrected from the image, and the coordinate is corrected. Subsequently, the processing unit stores the corrected coordinates in the storage unit.

JP 2010-107265 A (page 5-6, FIG. 1)

  However, the above-described data generation apparatus having the coordinate correction function already developed by the applicant has the following problems to be improved. That is, in the data generation apparatus that corrects the coordinates in the first procedure described above, an image showing the positions of all points on the multi-sided substrate 100 in absolute coordinates is displayed, and the absolute coordinates of the points selected from them are displayed. Configured to fix. Specifically, in this data generation apparatus, as shown in FIG. 12, for example, a multi-sided board formed by arranging four circuit boards A to D of the same type in parallel by rotating or rotating them into one sheet. The positions of points Pa to Pd corresponding to each other are displayed in absolute coordinates with the reference position P1 shown in FIG. In this state, when the point Pa of the circuit board (reference circuit board) A in the figure is moved by “10” along the X axis (that is, “10” on the right side) and by “0” along the Y axis, The absolute coordinates of the point Pa are corrected from (10, 10) to (20, 10). In addition, the points Pb to Pd corresponding to the point Pa in each circuit board B to D are determined by considering the relative positional relationship between the reference circuit board A and each circuit board B to D and the amount of movement of the point Pa. When moving by the same movement amount, the absolute coordinates of the points Pb to Pd are changed from (110, 10), (90, 190), (190, 190) to (120, 10), (80, 190), (180, 190). As described above, in this data generation apparatus, when the coordinates of the points corresponding to each other in each of the circuit boards A to D are corrected, according to the relative positional relationship between the reference circuit board A and the circuit boards B to D. Since the coordinates to be corrected are different, it is difficult to intuitively grasp the coordinates to be corrected. As a result, there is a problem that the coordinates to be corrected are likely to be erroneous.

  Further, in the data generation apparatus that corrects the coordinates in the second procedure, the position of each point in the reference circuit board is indicated by absolute coordinates, and the position of each point in other circuit boards excluding the reference circuit board is relatively An image indicated by coordinates is displayed on the display unit, and the coordinates of a point selected from the image are corrected. Specifically, in this data generation apparatus, as shown in FIG. 13, the position of the point Pa of the reference circuit board A on the multi-sided board 100 is displayed in absolute coordinates (10, 10) with the reference position P1 as the origin. Is done. Further, the positions of the points Pb to Pd corresponding to the point Pa on the other circuit boards B to D excluding the reference circuit board A are relative coordinates having the origin at the corresponding positions P2 to P4 corresponding to the reference position P1, that is, the point Pa. Are respectively displayed with the same coordinates (10, 10) as the coordinates indicating the position. In this case, as a result of measuring the position of the point Pd, there is a positional deviation between the designed position of the point Pd and the measured position, and in order to eliminate this positional deviation, along the X axis in FIG. When the coordinates are corrected by “−10” (that is, “10” on the left side) and by “0” along the Y axis, the coordinates of the point Pd are corrected from (10, 10) to (20, 10). That is, when the apparent position along the X axis is moved in the minus direction, it is necessary to increase the coordinates. As described above, in this data generation device, a value that causes a feeling as if the coordinate moves in the opposite direction depending on the relative positional relationship between the reference circuit board A and the other circuit boards B to D. The coordinates may be corrected. For this reason, in this data generation device, when such correction is performed, there is a problem that the coordinates to be corrected are likely to be erroneous.

  The present invention has been made in view of such a problem, and a main object of the present invention is to provide a data processing apparatus capable of accurately performing an operation of correcting the coordinates of a point for probing a probe.

  In order to achieve the above object, the data processing apparatus according to claim 1 is provided on the multi-sided board for probing an inspection probe in an electrical inspection for a multi-sided board formed by arranging a plurality of circuit boards of the same type in one. A storage unit for storing inspection data for specifying the position of a point specified in advance, a processing unit for executing a correction process for correcting the inspection data according to a correction operation, and an image based on the inspection data are displayed. A display control unit to be displayed on the display unit, wherein the display control unit is provided with the multi-surface predetermined as a reference circuit board based on the inspection data stored in the storage unit. A first display for displaying the positions of all the points in the multi-sided board with absolute coordinates having a reference position defined in advance on one circuit board in the board as an origin. The image and the position of the point in the reference circuit board are displayed in the absolute coordinates, and the position of the point in the other circuit board is displayed in relative coordinates with the corresponding position corresponding to the reference position as the origin. Either one of the second images is switched according to the selection operation and displayed on the display unit, and when the correction process is executed, the image being displayed is updated with the content of the correction process.

  The data processing device according to claim 2 is the data processing device according to claim 1, wherein the storage unit stores shape data specifying a planar shape of the multi-sided substrate, and the display control unit In the first image and the second image, the planar shape of the multi-sided substrate on which the points are plotted is displayed based on the shape data.

  In the data processing device according to claim 1, when the display control unit switches either one of the first image and the second image according to the selection operation to display on the display unit, and the correction process is executed. The displayed image is updated with the contents of the correction process. In this case, in the correction operation performed in the state where the first image is displayed, the positions of all the points are displayed in absolute coordinates. For example, this occurs between the position of the designed point and the measured position. When the coordinates of the point are corrected in order to eliminate the positional deviation, the coordinates can be corrected by inputting a coordinate value that directly reflects (increases / decreases) the positional deviation amount. As a result, unlike the correction operation performed in the state where the position of the point is displayed in the relative coordinates, depending on the relative positional relationship between the reference circuit board and other circuit boards, the coordinates may move in the opposite direction. Since the coordinates are not corrected to values that cause such a feeling, an error in the input coordinate values is prevented, and the coordinate correction operation can be performed accurately. Further, in the correction operation performed in a state where the second image is displayed, for example, when the coordinates of the points corresponding to each other are corrected, the correction is performed according to the relative positional relationship between the reference circuit board and the circuit board. Since it is possible to input and correct the same coordinate value without changing the power value, it is easy to make an input mistake when inputting a different coordinate value for each circuit board, or for each circuit board. As a result of being able to reliably prevent a situation where the coordinates are corrected to an incorrect coordinate due to a calculation error when calculating the coordinate value, the coordinate correcting operation can be performed accurately. Therefore, according to this data processing device, the first image and the second image are switched and displayed according to the mode, and the correction operation is performed in that state. Work can be performed accurately.

  According to the data processing device of claim 2, the display control unit displays the planar shape of the multi-sided substrate on which the points are plotted in the first image and the second image, thereby providing multi-sided attachment. The point to be corrected in the substrate can be easily found. For this reason, according to this data processing device, the efficiency of the correction work for correcting the coordinates of the points can be sufficiently improved.

  First, the configuration of the data processing apparatus 1 shown in FIG. 1 as an example of the data processing apparatus will be described. As shown in FIG. 6, the data processing apparatus 1 includes an operation unit 2, a display unit 3, a storage unit 4, and a control unit 5. As an example, an electrical inspection for the multi-sided substrate 100 shown in an image in FIG. 6. The data (specifically, reference coordinate data Db and offset data Dd, which will be described later) for specifying the position of a point on the circuit board with which the inspection probe is brought into contact with the inspection probe can be corrected. In this case, the multi-sided substrate 100 is a substrate in which a plurality of circuit boards of the same type are arranged side by side, and in this example, as shown in FIG. The four circuit boards A to D are arranged and formed in each region divided into two. The circuit boards C and D are arranged in a state where the circuit boards A and B are rotated by 180 °. By arranging the circuit boards A to D in this way, the multi-sided board 100 is configured to be point-symmetric with respect to the center of the multi-sided board 100 as a symmetric point.

  Also, in the electrical inspection described above, as an example, in one inspection step (inspection process), in the state of probing one probe (two in total) at two points, a conductor pattern disconnection inspection or an electronic component Inspection (constant inspection) is performed. For this reason, in this electrical inspection, the inspection step is executed a plurality of times while changing the combination of each point.

  As an example, the operation unit 2 includes a keyboard and a mouse as a pointing device, and outputs an operation signal to the control unit 5 in accordance with the operation. The display unit 3 displays various images under the control of the control unit 5. Specifically, the control unit 5 displays a first image (first image) Ga and a second image (second image) Gb described later.

  The storage unit 4 includes, for example, a magnetic storage medium, a RAM, and the like, and stores an operation program for the control unit 5. Further, the storage unit 4 stores the design data of the multi-sided board 100 to be inspected (data that can specify the shape of the wiring pattern on the multi-sided board 100, the mounting position of the electronic component mounted on the multi-sided board 100, etc.). The inspection step data Da, the reference coordinate data Db, the relative data Dc, the offset data Dd, and the shape data De generated in advance are stored. These data Da to De are examples of inspection data, and as described above, the position of the point on the multi-sided substrate 100 with which the inspection probe is brought into contact when the electrical test is performed on the multi-sided substrate 100. Used to identify

  In this case, as conceptually shown in FIG. 2, the inspection step data Da includes step numbers indicating the order of inspection steps executed in the electrical inspection of the multi-sided substrate 100 (parts of which are “ Information (numbers of S1 to S4) and codes (hereinafter referred to as “probing target points”) for identifying probing targets in each inspection step (“Pa1 to P5” showing some of them). , P7, P8 ") information.

  Further, as conceptually shown in FIG. 3, the reference coordinate data Db is a circuit board (for example, circuit board A: predetermined) as a reference circuit board among the circuit boards A to D in the multi-sided board 100. Hereinafter, information of codes (also referred to as “Pa1 to Pa4” indicating part of them in the same figure) for identifying all points in the “reference circuit board A”), and coordinates of each point (X coordinate and Y coordinate) information is associated with each other. In this case, the coordinates (hereinafter also referred to as “absolute coordinates”) having the reference position P1 (see FIG. 6) defined in the reference circuit board A as the origin are adopted as the coordinates of the points in the reference coordinate data Db. .

  Further, the relative data Dc is data indicating the relative positional relationship between the circuit boards B to D other than the reference circuit board A and the reference circuit board A. As shown conceptually in FIG. Information indicating the separation distance along the X axis and the Y axis between the center of the circuit board A and the centers of the circuit boards B to D, and information indicating the rotation angle of the circuit boards B to D with respect to the reference circuit board A It is configured to include.

  The offset data Dd is configured to include information indicating offset values that can be individually set for every point in the multi-sided substrate 100. This offset value is used to move only one position among points corresponding to each other (for example, four points Pa1, Pb1, Pc1, and Pd1 shown in FIG. 6) in each of the circuit boards A to D. Specifically, the position of the point where the offset value is set is defined as a position moved by an offset value (distance along the X and Y axes) relative to the position of the other points corresponding to each other. The In the initial state, the offset value of each point is set to (0, 0).

  The shape data De is shape data for specifying the planar shape of the multi-sided board 100 and includes information indicating the outline of the multi-sided board 100 and the outlines of the circuit boards A to D.

  The control unit 5 functions as a display control unit and a processing unit, and controls each unit constituting the data processing device 1 and executes various processes. Specifically, the control unit 5 selects one of the first image Ga and the second image Gb based on the inspection data (each data Da to De) stored in the storage unit 4 according to the selection operation. Switch to display on display unit 3

  In this case, as shown in FIG. 6, the first image Ga includes an image (hereinafter also referred to as “first coordinate image Gc”) that displays a list of the positions of all points in the multi-sided substrate 100 in absolute coordinates, An image (hereinafter also referred to as “substrate image Gd”) in which each point (dot indicating a point) is plotted in a plan view showing a planar shape of the attached substrate 100, and an inspection performed in an electrical inspection on the multi-sided substrate 100 It is composed of an image (hereinafter also referred to as “inspection step image Ge”) that displays a list of points to be probed in the step.

  Further, as shown in FIG. 9, the second image Gb displays the position of each point in the reference circuit board A in absolute coordinates, and also shows the points in the other circuit boards B to D excluding the reference circuit board A. Coordinates (hereinafter, referred to as absolute coordinates) with corresponding positions P2 to P4 corresponding to the reference position P1 (positions moved from the reference position P1 by the positional relationship specified by the relative data Dc) as origins, respectively. An image (hereinafter also referred to as “relative coordinates”) (hereinafter referred to as “second coordinate image Gf”), and the substrate image Gd and the inspection step image Ge described above.

  Further, the control unit 5 functions as a processing unit, and executes a correction process for correcting the reference coordinate data Db and the offset data Dd according to a correction operation using the operation unit 2. Specifically, the control unit 5 sets an offset value for the point of the correction operation target (correction target) in the offset data Dd when the correction operation is performed while the first image Ga is displayed. In addition, the offset data Dd is stored (overwritten) in the storage unit 4. Thus, by correcting the offset value for the correction target point in the offset data Dd, only the coordinates of the correction target point can be corrected.

  The control unit 5 corrects the absolute coordinates corresponding to the point to be corrected in the reference coordinate data Db when the correction operation is performed while the second image Gb is displayed, and the corrected reference coordinates Data Db is stored (overwritten) in the storage unit 4. In this way, by correcting the absolute coordinates in the reference coordinate data Db, the corresponding position P2 moved from the reference position P1 by the positional relationship specified by the relative data Dc is represented by the same value as the absolute coordinates with the origin as the origin. The relative coordinates that are made can also be substantially modified.

  Further, when executing the correction process, the control unit 5 updates and displays the image (first image Ga or second image Gb) displayed on the display unit 3 with the content of the correction process.

  Next, a method for correcting the reference coordinate data Db and the offset data Dd as inspection data using the data processing device 1 and the operation of the data processing device 1 at that time will be described with reference to the drawings. In this case, inspection step data Da (see FIG. 2), reference coordinate data Db (see FIG. 3), relative data Dc (see FIG. 4), offset data Dd (see FIG. 5), and shape data De are stored in the storage unit 4 in advance. It shall be remembered.

  First, the operation unit 2 is operated to instruct reading of the inspection step data Da, the reference coordinate data Db, the relative data Dc, the offset data Dd, and the shape data De. At this time, the operation unit 2 outputs an operation signal, and the control unit 5 reads each data Da to De from the storage unit 4 according to the operation signal.

  Next, the operation unit 2 is operated to select one of the first image Ga and the second image Gb, and display of the selected image is instructed. Here, when correction processing is performed while the first image Ga is being displayed, the reference coordinates are simply set (or corrected) in the offset data Dd for the corrected point correction target point. Since the absolute coordinates in the data Db are not corrected, the first image Ga is selected when only the coordinates of the points of one circuit board among the circuit boards are corrected.

  When the display is instructed by selecting the first image Ga, the control unit 5 follows the operation signal output from the operation unit 2 and based on the data Da to De read from the storage unit 4, the first image Ga. Is displayed on the display unit 3.

  Specifically, the control unit 5 reads out the information on the step number of each inspection step executed in the electrical inspection on the multi-sided substrate 100 and the information on the code for identifying the probing target point in each inspection step. Extracted from the inspection step data Da. Further, the control unit 5 extracts information on absolute coordinates of all points in the reference circuit board A from the read reference coordinate data Db. Further, the control unit 5 extracts information indicating the relative positional relationship between the circuit boards B to D and the reference circuit board A from the read relative data Dc. Further, the control unit 5 determines whether or not there is a point for which an offset value is set in the read offset data Dd, and if there is, extracts information on the offset value.

  Next, the control unit 5 selects the circuit boards B to B based on the absolute coordinates of each point in the extracted reference circuit board A and the numerical values indicating the relative positional relationship between the circuit boards B to D and the reference circuit board A. Specify the absolute coordinates of each point in D. Subsequently, when there is a point for which an offset value is set, the control unit 5 corrects the absolute coordinate of the point with the offset value.

  Next, the control unit 5 specifies the planar shape of the multi-sided substrate 100 based on the read shape data De, the substrate image Gd in which each point is plotted in the plan view showing the planar shape, and all the points. A first image Ga composed of a first coordinate image Gc displaying a list of positions in absolute coordinates (or corrected absolute coordinates) and an inspection step image Ge displaying a list of probing target points in each inspection step is displayed. Image data is generated. Next, the control unit 5 outputs the generated image data to the display unit 3 to display the first image Ga on the display unit 3 as shown in FIG.

  Here, for example, as a result of measuring the position of the point Pd1 shown in FIG. 6, there is a deviation between the designed coordinates of the point Pd1 and the measured coordinates. In order to eliminate this deviation, the coordinates of the point Pd1 When correcting the above, a selection operation is performed using the operation unit 2. Specifically, as shown in FIG. 7, the mouse of the operation unit 2 is operated to move the cursor (pointer) to the display position of the coordinates of the point Pd1 in the first coordinate image Gc of the first image Ga, and then Click the mouse to select the coordinates. The selection may be made by moving the cursor to the point Pd1 plotted in the board image Gd. At this time, in accordance with the operation signal output from the operation unit 2, the control unit 5 displays an input image Gi for inputting coordinates in the vicinity of the display position of the selected coordinates.

  Subsequently, a correction operation is performed using the operation unit 2. Here, in the first image Ga, the positions of all points on the multi-sided substrate 100 are displayed in absolute coordinates with the reference position P1 as the origin. For this reason, when the position of the point Pd1 is measured with the reference position P1 as the origin, the amount of positional deviation between the measured value and the absolute coordinate is, for example, “−10” along the X axis in FIG. 10 "), when the value is" 0 "along the Y axis, the absolute coordinates may be corrected by reflecting this value as it is. Specifically, as shown in FIG. 7, the coordinates of the point Pd1 are changed from (190, 190) to (180, 190) by inputting a numerical value in the input image Gi using the keyboard of the operation unit 2. Correct it. As described above, in the correction operation performed while the first image Ga is displayed, the coordinates can be corrected by inputting the coordinates in which the positional deviation amount is reflected (increased / decreased) as it is. The situation where the coordinates are corrected is prevented, and the coordinates can be corrected accurately.

  Next, the control unit 5 executes correction processing to set the offset value for the point Pd1 in the offset data Dd to the above-described difference value (−10, 0), and the offset data Dd (corrected) The offset data Dd) is stored (overwritten) in the storage unit 4. Moreover, the control part 5 updates and displays the 1st image Ga with the content of the correction process. Specifically, as shown in FIG. 8, the control unit 5 updates the coordinates of the point Pd1 that is the target of the correction process displayed in the first image Ga to the corrected coordinates and displays them. Further, the control unit 5 updates the position of the point Pd1 to the corrected coordinate position in the plan view and displays it. Next, when there are other coordinates to be corrected, the above selection operation and correction operation are performed. At this time, the control unit 5 executes the correction process described above.

  On the other hand, when the correction process is performed while the second image Gb is displayed, the absolute coordinates corresponding to the point to be corrected in the reference coordinate data Db are corrected, and the relative coordinates are substantially corrected accordingly. Is done. That is, by correcting the coordinates of a point on one circuit board, the coordinates of the points on another circuit board corresponding to the point can also be corrected at once. Therefore, the second image Gb is selected when the coordinates of points corresponding to each other on each circuit board are corrected by a single correction operation.

  When the operation unit 2 is operated to select and display the second image Gb, the control unit 5 follows the operation signals output from the operation unit 2 to read each data Da to data read from the storage unit 4. Based on De, the second image Gb is displayed on the display unit 3.

  Specifically, as described above, the control unit 5 extracts each piece of information (step number information, code information, absolute coordinate information) from each of the data Da to De. Next, the control unit 5 determines the absolute coordinates of each point on the extracted reference circuit board A and the numerical values indicating the relative positional relationship between the circuit boards B to D and the reference circuit board A on the circuit boards B to D. Identify the relative coordinates of each point. Subsequently, when there is a point for which an offset value is set, the control unit 5 corrects the absolute coordinate or relative coordinate of the point with the offset value.

  Next, the control unit 5 displays a list of the board image Gd and the position of the point on the reference circuit board A in absolute coordinates (or corrected absolute coordinates) and the position of the points on the circuit boards B to D in relative coordinates (or The image data for displaying the second image Gb composed of the second coordinate image Gf displayed as a list with the corrected relative coordinates) and the inspection step image Ge is generated. Next, the control unit 5 outputs the generated image data to the display unit 3 to display the first image Ga on the display unit 3 as shown in FIG.

  Here, for example, there is a positional deviation between the position where the points Pa1, Pb1, Pc1, Pd1 shown in FIG. 9 are measured and the designed position, and each point Pa1, Pb1 is used to eliminate this positional deviation. , Pc1 and Pd1 are corrected using the operation unit 2 to correct the coordinates. Specifically, as shown in FIG. 10, by operating the mouse of the operation unit 2, one of the points Pa1, Pb1, Pc1, Pd1 in the second coordinate image Gf of the second image Gb (for example, The cursor (pointer) is moved to the position where the coordinates of the point Pa1) are displayed, and then the mouse is clicked to select the coordinates. The selection may be made by moving the cursor to the point Pa1 plotted in the substrate image Gd.

  Subsequently, a correction operation is performed using the operation unit 2. Specifically, as shown in FIG. 10, the coordinates of the point Pa1 are changed from (10, 10) to (20, 10) by inputting a numerical value in the input image Gi using the keyboard of the operation unit 2. Correct it.

  Next, the control unit 5 executes correction processing to correct the coordinates (absolute coordinates) of the point Pa1 in the reference coordinate data Db from (10, 10) to (20, 10), and the corrected reference coordinate data. Db is stored (overwritten) in the storage unit 4. Moreover, the control part 5 updates and displays the 2nd image Gb with the content of the correction process. Specifically, as shown in FIG. 11, the control unit 5 updates the coordinates (absolute coordinates) of the point Pa1 that is the target of the correction process displayed in the second image Gb to the corrected coordinates. Display. Further, the coordinates (relative coordinates) of the points Pb1, Pc1, and Pd1 corresponding to the point Pa1 on the circuit boards B to D are updated to the corrected coordinates and displayed. Further, the positions of the points Pa1, Pb1, Pc1, and Pd1 in the plan view are updated to the corrected coordinate positions and displayed. Next, when there are other coordinates to be corrected, the above selection operation and correction operation are performed. At this time, the control unit 5 executes the correction process described above.

  When the correction operation is performed on the coordinates (relative coordinates) of the points Pb1, Pc1, and Pd1 instead of the point Pa1, the correction is performed by inputting the same value as that in the correction operation on the absolute coordinates of the point Pa1. Do. In the above example, the correction is made from (10, 10) to (20, 10). As described above, in the correction operation performed in the state where the second coordinate image Gf is displayed, when correcting the coordinates of the points corresponding to each other, the relative positional relationship between the reference circuit board A and the circuit boards B to D is determined. Since it is possible to perform correction by inputting the same coordinate value without changing the coordinate value to be corrected according to the input, an input that is likely to occur when a different coordinate value is input for each of the circuit boards A to D. As a result of preventing errors and correction to incorrect coordinates due to calculation errors when calculating different coordinate values for each of the circuit boards A to D, the coordinate correction operation can be performed accurately. It has become.

  Subsequently, when the correcting operation and the correcting process for all the coordinates to be corrected are completed, the ending operation is performed using the operation unit 2. In response to this, the control unit 5 executes an end process.

  As described above, in the data processing device 1, the control unit 5 switches either one of the first image Ga and the second image Gb according to the selection operation and causes the display unit 3 to display the correction process. Sometimes the image being displayed is updated with the contents of the correction process. In this case, in the correction operation performed in a state where the first image Ga is displayed, the positions of all points are displayed in absolute coordinates. For example, this occurs between the position of the designed point and the measured position. When the coordinates of the point are corrected in order to eliminate the positional deviation, the coordinates can be corrected by inputting a coordinate value that directly reflects (increases / decreases) the positional deviation amount. Therefore, unlike the correction operation performed in a state where the second image Gb displaying the position of the point in relative coordinates is displayed, depending on the relative positional relationship between the reference circuit board A and the other circuit boards B to D. Does not correct the coordinates to a value that causes the sense that the coordinates move in the opposite direction, so that it is possible to prevent the mistake of the input coordinate values and to correct the coordinates accurately. . Further, in the correction operation performed while the second image Gb is displayed, when correcting the coordinates of the points corresponding to each other, according to the relative positional relationship between the reference circuit board A and the circuit boards B to D. Since it is possible to perform correction by inputting the same coordinate value without changing the coordinate value to be corrected, an input mistake that is likely to occur when inputting a different coordinate value for each of the circuit boards A to D, As a result of being able to reliably prevent a situation in which correction is made to an incorrect coordinate due to a calculation error when calculating different coordinate values for each of the circuit boards A to D, the coordinate correction operation can be performed accurately. . Therefore, according to this data processing device 1, the first image Ga and the second image Gb are switched and displayed according to the mode, and the correction operation is performed in that state. Correction work can be performed accurately.

  Further, according to the data processing apparatus 1, the controller 5 displays the planar shape of the multi-sided substrate 100 on which points are plotted in the first image Ga and the second image Gb, so that the multi-sided substrate 100 is displayed. The point to be corrected can be easily found. For this reason, according to this data processor 1, the efficiency of the correction work which corrects the coordinates of a point can fully be improved.

  Note that the data processing device 1 is not limited to the configuration described above. For example, the form of the first image Ga and the second image Gb is not limited to the form described above, and can be arbitrarily changed. Specifically, the first image Ga composed only of the first coordinate image Gc and the second image Gb composed only of the second coordinate image Gf are employed without displaying the substrate image Gd and the inspection step image Ge. You can also. In addition, the first image Ga and the second image Gb in which coordinates are displayed in the vicinity of the points plotted on the substrate image Gd can be employed.

  Moreover, although the example which operates the keyboard of the operation part 2 and inputs a coordinate numerically was mentioned above, a coordinate can also be corrected with another operation method. For example, it is possible to adopt a configuration in which the coordinates are corrected by operating the mouse to increase or decrease the coordinate values.

  In addition, although the configuration example including the operation unit 2, the display unit 3, and the storage unit 4 has been described above, the configuration including no operation unit, that is, the operation unit, the display unit, and the storage unit as an external device of the data processing device 1 is provided. A configuration to be used can also be adopted.
