FIG.

The priority color table 1 shown in FIG.
Reference numeral 801 includes a priority and a display color. Further, although the priority order is from 1 to 6, it may be higher or lower. The failure frequency color table 1802 includes the number of failures and the display color. Further, the location name text color table 1803 is composed of a priority and a display color, and the display color is set to a color that stands out from the color of the priority color table 1801.

The operation will be described below with reference to the flow charts of FIGS.

Step S1601: Gerber data, mount data, and actual failure candidate data are read from the failure information database of the printed board unit.

Step S1602: The occupied area of the location is calculated from the coordinates of the mount data, and the actual fault candidate data is rearranged in the descending order of the occupied area of the location.

Step S1603: The head of the actual fault candidate data is set to the pointer P.

Step S1604: If the fault content of the actual fault candidate data pointed to by the pointer P is a component fault, the drawing layer is set to 1 if it is a manufacturing fault, and the drawing layer is set to 2 if it is a manufacturing fault.

Step S1605: A fill color corresponding to the priority order of the actual failure candidate data indicated by the pointer P is set with reference to the priority order color table.

Step S1606: The coordinates corresponding to the location name of the actual fault candidate data pointed to by the pointer P are obtained from the mount data, and the figure of the coordinates and the data for displaying the fault content and the number of faults at the location in a pop-up window are set. Draw on the layer.

Step S1607: It is determined whether or not the setting of the failure status display mode of the storage device is text. If it is text, the process proceeds to step S1608, and if it is not text, the process proceeds to step S1611.

Step S1608: Step S1606
Fills the shape drawn in with the specified fill color.

Step S1609: The color of the location name text corresponding to the priority of the actual failure candidate data pointed to by the pointer P is set with reference to the location name text table.

Step S1610: Referring to the fault status of the actual fault candidate data pointed by the pointer P, the inclination angle at the time of drawing the location text name is determined by the fault status (100%).
Is set to an inclination angle of 0 degree, and the inclination is set to 1 degree per 1%. Then, the process proceeds to step S1614.

Step S1611: Referring to the number of failures in the actual failure candidate data indicated by the pointer P, the number of failures is 1
In other words, if the failure occurred for the first time, the fill pattern is staggered and the inside of the figure drawn in step S1606 is painted. If the number of failures is two or more, the failure status is referred to. If the failure state exceeds 100%, it is determined that the color is in the improving direction, and if the failure situation exceeds 100%, the color is in the deteriorating direction. The inside of the drawn shape.

Step S1612: The color of the location name text corresponding to the priority of the actual failure candidate data pointed to by the pointer P is set with reference to the location name text table.

Step S1613: The inclination angle at the time of drawing the location text name is set to 0 degrees.

Step S1614: Step S1606
The angle is set at the center of the location name text at the center of the figure drawn with, and the alphabet is drawn larger than the number.

Step S1615: The pointer P is updated so as to point to the next actual failure candidate data.

Step S1616: It is determined whether all the actual fault candidate data have been processed. If the processing has been performed, the process proceeds to step S1617. If the processing has not been performed, the process proceeds to step S1617.
It returns to 1604.

Step S1617: Write data to WWW
Register in the Web data of the server. Then, the process ends.

By creating the actual fault candidate position drawing data in this manner, for example, even if there is a small location below a certain location, the small location is displayed as shown in FIG. Therefore, the location can be easily found.
In addition, the failure status is displayed by the inclination angle of the location name text as shown in FIG.
Since the location is displayed in the fill pattern of the location as shown in (b), the failure situation can be grasped only by looking at the failure candidate position drawing.

Further, when the cursor is pointed at the location of the fault candidate position drawing as shown in FIG. 21, fault information such as the fault content and the number of faults at the location is displayed, so that the fault information can be quickly obtained when necessary. Operability can be improved.

FIG. 22 shows an embodiment of the supplementary explanation of the failure candidate position display screen. In order to display the failure candidate position drawing displayed in the failure candidate position display frame in a large size, the phenomenon name list frame and the priority color frame are displayed in a small size. For this reason, the phenomenon names are abbreviated, and the explanation of the meaning of colors is omitted.

In such a case, in order to supplement the phenomenon name and meaning, a phenomenon name in the phenomenon name list frame, for example, D
The details of the phenomenon name are displayed in a pop-up window (arrow A in FIG. 22) when the cursor is held over ISP1, or the meaning of the color is displayed in a pop-up window (arrow B in FIG. 22) when the cursor is moved over the color box of the priority color frame. ).

In this example, when the cursor is moved over the phenomenon name, the details of the phenomenon name are displayed. However, the details of the phenomenon may be displayed instead of the details of the phenomenon name.

In the pop-up window, the object on which the cursor is held is an image file, and the
This can be easily realized by designating the text shown in the popup window in the ALT attribute of the MG tag.

By displaying the details of the phenomenon name and the meaning of the color box in a pop-up window in this way, it is not necessary to remember the details of the operation screen, and anyone can use it easily.
