The storage unit 13 stores inspection data Dt. In addition, the storage unit 13 stores wiring data Da and electrical component data Db used in the first display process and the second display process executed by the control unit 14. In this case, the wiring data Da is configured by, for example, gerber data that can specify the shape and arrangement position of each wiring W of the component mounting board 100. Further, the electrical component data Db is information that can specify the type and standard (for example, the standard value Rs of the resistance value) for each electrical component E of the component mounting board 100, and the shape and location of each electrical component E. It is comprised including.

  The control unit 14 executes various processes based on the operation signal output from the operation unit 11 and controls the display unit 12 and the inspection unit 3. Further, the control unit 14 functions as a processing unit, creates inspection data Dt based on an operation signal output from the operation unit 11, and stores it in the storage unit 13. Here, the inspection data Dt includes, for example, inspection contents, point information indicating the wiring W as an inspection point for supplying an inspection signal S (an example of an electrical signal), and guard points (Hi side of the inspection signal S). Point information indicating the wiring W as an inspection point to function as the wiring W to be supplied), the standard value Rs of the electrical component E, and a reference value for quality determination for determining the quality of the electrical component E (For example, a resistance reference value Rr) is described for each electrical component E to be inspected.

In this case, the list T is a table showing the contents of the inspection data Dt. As shown in FIG. 4, the inspection contents, inspection points, standard value Rs, and reference value Rr included in the inspection data Dt are electrical. Each component E is arranged in a list form.

  In addition, when one of the electrical components E displayed in the list T is selected in a state where the list T is displayed, the control unit 14 executes the second display process and performs the layout drawing F. (See FIGS. 3 and 5) is displayed on the display unit 12.

  In addition, when the selection operation for selecting the wiring W illustrated in the layout drawing F is performed, the control unit 14 receives information (for example, the code of the wiring W) indicating the wiring W selected by the selection operation. The inspection data Dt is created as input as point information, and the code of the wiring W is displayed in the list T.

  As shown in FIG. 1, the inspection unit 3 includes a substrate holder 21, a probe unit 22, a probing mechanism 23, a scanner unit 24, an inspection signal generation unit 25, and a measurement unit 26.

  The board holding table 21 is configured to hold the component mounting board 100. The probe unit 22 includes a plurality of probe pins 31 that can contact each wiring W of the component mounting board 100 and is configured in a jig shape.

  The scanner unit 24 includes a plurality of switches (not shown), and switches each switch to an on state or an off state according to the control of the control unit 14, whereby the probe pin 31 and the inspection signal of the probe unit 22 are transferred. Connection / disconnection (connection and disconnection) with the generation unit 25 and connection / disconnection between the probe pin 31 and the measurement unit 26 are performed. The inspection signal generator 25 generates an inspection signal S (for example, a DC constant current signal). The measurement unit 26 measures the resistance value of the electrical component E based on the voltage value of the voltage generated at both ends of the electrical component E by the supply of the inspection signal S and the current value of the inspection signal S.

  Next, a data creation method for creating inspection data Dt for the component mounting board 100 shown in FIG. 2 using the board inspection apparatus 1, and a component mounting board using the board inspection apparatus 1 based on the inspection data Dt. A method for inspecting 100 will be described with reference to the drawings.

  Prior to the inspection, inspection data Dt for the component mounting board 100 is created. In creating the inspection data Dt, the operation unit 11 is operated to instruct the start of processing. At this time, the operation unit 11 outputs an operation signal, and the control unit 14 executes the first display process according to the operation signal. In the first display process, the control unit 14 reads the wiring data Da and the electrical component data Db from the storage unit 13.

  Next, the control unit 14 determines in advance the type (name) of each electrical component E on the component mounting board 100, the inspection content corresponding to each electrical component E, and each electrical component E based on the electrical component data Db. A standard value Rs and a reference value Rr are specified. In this example, the control unit 14 specifies the reference value Rr as the same value as the standard value Rs. Next, the control unit 14 generates image data necessary to display a list T in which these pieces of information are arranged in a list form for each electrical component E. Subsequently, the control unit 14 outputs the generated image data to the display unit 12. As a result, the list T is displayed on the display unit 12 as shown in FIGS.

  Next, inspection point information (point information) for each electrical component E is input. Specifically, by operating a cursor key or a mouse on the keyboard of the operation unit 11, as shown in FIG. 4, one of the electrical components E displayed in the list T (for example, a resistor R1) Select. At this time, the control unit 14 enters the column in the list T to which the inspection point information should be input for the selected resistor R1 (for example, the “Hi side” column of the “inspection point” shown in the figure). A cursor (thick frame shown in the figure) is displayed.

  Next, the control unit 14 executes the second display process according to the operation signal output from the operation unit 11. In the second display process, the control unit 14 selects the electrical component selected from the electrical components E displayed in the list T based on the wiring data Da and the electrical component data Db read from the storage unit 13. E (in this example, the resistor R1), the wiring W (in this example, the wirings W1, W2) directly connected to the resistor R1, and the wirings W1, W2 The other electrical component E (in this example, the resistor R2 in the state where the electrical component E is not connected to the wiring W1 and the resistors R2, R6, R7 are directly connected to the wiring W2) , R6, R7), the image data necessary to display the layout F showing the layout is generated. Subsequently, the control unit 14 outputs the generated image data to the display unit 12. Thereby, as shown in FIG. 5, the layout drawing F is displayed on the display unit 12.

  Next, with reference to the layout diagram F, the wiring W to be an inspection point for the resistor R1 is determined. Next, for example, when the wiring W1 (see FIG. 5) is determined as the inspection point for supplying the inspection signal S on the Hi side, as shown in FIG. In this case, a selection operation is performed in which an image of a line segment indicating the wiring W1 or an image of a symbol “W1” indicating the wiring W1) is selected by clicking with the mouse of the operation unit 11.

  At this time, the control unit 14 assumes that information indicating the wiring W1 selected by the selection operation (a symbol of the wiring W1) is input as point information in accordance with the operation signal output from the operation unit 11, as shown in FIG. Thus, the code is displayed in the list T (in the column “Hi side” of “inspection point” shown in the figure). Further, as shown in the figure, the control unit 14 enters a column in the list T to which information on the next inspection point is to be input (for example, a column “Lo side” of “inspection point” shown in the figure). A cursor (thick frame shown in the figure) is displayed.

  Next, for example, when the wiring W2 (see FIG. 5) is determined as the inspection point for supplying the inspection signal S on the Lo side, a selection operation for selecting the wiring W2 illustrated in the operation layout diagram F is performed. At this time, assuming that the code of the wiring W2 is input as the point information, the control unit 14 displays the code in the “Lo side” column of “inspection point” in the list T as shown in FIG. Let In addition, the control unit 14 causes the cursor to be displayed in a column in the list T to which information on the next inspection point is to be input (for example, a “guard P” column of “inspection point” shown in the figure).

  In this case, when there is no inspection point (wiring W) to be set as a guard point for the resistor R1, the input of the inspection point for the resistor R1 is terminated, and then each of the items displayed in the list T is displayed. Another one of the electrical components E (eg resistor R2) is selected. At this time, the control unit 14 executes the second display process described above, and selects the selected resistor R2, the wirings W2 and W3 directly connected to the resistor R2, and the wirings W2 and W3. Arrangement drawing F showing arrangement with resistors R1, R3, R4, R6, and R7 (see FIG. 2) directly connected is displayed on display unit 12. Next, when the wiring W to be the inspection point for the resistor R2 is selected by the selection operation, the control unit 14 displays the code of the selected wiring W in the list T as described above.

  Thereafter, similarly, each electric component E displayed in the list T is selected one by one, and the wiring W to be an inspection point for each electric component E is selected by a selection operation. Thereby, the control part 14 displays the code | symbol of the selected wiring W in the list T, as shown in FIG. Thus, the input of the point information for each electrical component E is completed. Next, the control unit 14 creates inspection data Dt including information on the inspection point input as described above, and stores it in the storage unit 13. Thus, the creation of the inspection data Dt for the component mounting board 100 is completed.

  Next, the component mounting board 100 is inspected. Specifically, the component mounting board 100 is placed and held on the board holding table 21 of the inspection unit 3. Subsequently, the operation unit 11 is operated to instruct the start of inspection. At this time, the control unit 14 moves the probe unit 22 by controlling the probing mechanism 23 of the inspection unit 3 according to the operation signal output from the operation unit 11. Thereby, the tip of each probe pin 31 of the probe unit 22 is brought into contact (probing) with each wiring W of the component mounting board 100.

  Next, the control unit 14 performs an inspection process. In this inspection process, the control unit 14 reads the inspection data Dt from the storage unit 13, and subsequently, for the electrical component E (for example, the resistor R1 shown in FIG. 2) to be inspected first based on the inspection data Dt. Identify inspection points. Next, the control unit 14 controls the inspection signal generation unit 25 of the inspection unit 3 to generate the inspection signal S. Subsequently, the control unit 14 controls the scanner unit 24 of the inspection unit 3 to inspect the probe pins 31 that are in contact with the wiring W (in this example, the wirings W1 and W2) set as the inspection point. The signal generation unit 25 and the measurement unit 26 are connected. As a result, the inspection signal S generated by the inspection signal generator 25 is supplied between the wirings W1 and W2.

  Next, the measurement unit 26 measures the resistance value based on the voltage value of the voltage between the wirings W <b> 1 and W <b> 2 generated by the supply of the inspection signal S and the current value of the inspection signal S. Subsequently, the control unit 14 compares the measurement value measured by the measurement unit 26 with the reference value Rr for quality determination included in the inspection data Dt to determine the quality of the resistor R1. Next, the control unit 14 executes the above-described processes, and performs inspection for other electrical components E. In addition, the control unit 14 causes the display unit 12 to display the determination result for each electrical component E.

  As described above, in this board inspection apparatus 1, data creation apparatus 2, and data creation method, the information on the wiring W (code of the wiring W) selected by the selection operation for selecting the wiring W in the layout drawing F is used as point information. Inspection data Dt is created.
