Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for confirming an electronic component mounted on a printed circuit board, and more particularly to a monitor screen for a process of designing a wiring pattern of the printed circuit board by CAD and a mounting state of the electronic component when the design is completed. The present invention relates to a display method in a printed circuit board system of a type that is confirmed by the following.

[0002]

2. Description of the Related Art In recent years, CAD has been used for designing wiring patterns on printed circuit boards, and even when designing and mounting a complicated circuit, the CAD can be easily and accurately designed in a short time. Printed circuit board design systems are currently widely used. Here, C
AD is an abbreviation for Computer Aided Desegn, which is a type of computer software.

In this design system, it is necessary to confirm whether the design is correct or not at any time, such as at the time of the printed circuit board design process or at the time of completion. Therefore, the monitor function of the CAD is required. Utilizing this, the image of the printed circuit board that is being held as data at that time is displayed on the monitor, and the mounting status of the components (electronic components) is
Conventionally, a method that allows the user (user) to confirm has been widely adopted.

FIG. 4 shows an example of an image display of a printed circuit board on a monitor surface according to the prior art. In the figure, M is a monitor surface, on which a printed circuit board 1 is displayed. As described above, some components 6 and 7 to be mounted at an arbitrary time during the design process or at the time of completion of the design are displayed, and 8 is the coordinate origin of the printed circuit board.

Here, the printed board 1 is a double-sided wiring board having a wiring pattern on both the A side (one side, for example, the front side) and the B side (the other side, for example, the back side). The component 6 is mounted on the surface A of the printed circuit board 1, and the component 7 is mounted on the surface B.

In such a design system, a designer instructs a display to the system as needed,
In response to this, as shown in FIG. 4, the monitor surface M on which the image of the printed circuit board 1 is displayed is observed, and an arrangement is made such that necessary components can be surely mounted in an appropriate state at that time. The design work of the printed circuit board is advanced while verifying whether or not the printed circuit board is formed, and a required printed circuit board is created.

In verifying the mounting state of such electronic components, it is necessary to sequentially check whether or not a large number of components to be mounted are all placed without any omission. Using a parts list as shown in FIG. 5, a check is made as needed by comparing the part names with the parts displayed on the monitor surface M, and it is confirmed that the components are securely mounted without omission. .

However, at this time, if the number of components mounted on the printed circuit board 1 is large, where the component arbitrarily selected from the component list is on the printed circuit board 1 displayed on the monitor surface M There is a problem that it takes a long time to find.

In particular, in recent years, the number of components mounted on a printed circuit board has increased, and in some cases has increased to several hundreds. Therefore, even if the printed circuit board 1 displayed on the monitor surface M is viewed, the component may be located anywhere. It's not clear whether it's in the air or not, so not only does it take a lot of concentration and time to find it, but sometimes it's impossible to find it.

Therefore, in the prior art, in order to be able to easily find the part concerned and to easily confirm the mounting position and the mounting surface, the necessary part name is input to the system. As shown, the component is highlighted 9.

Here, as shown in the figure, the highlighting 9 makes the outline of the part R1 a thick line so that only the part is conspicuous among many parts. The component can be easily found, and the mounting position and mounting surface can be easily confirmed.

As a method of highlighting in the prior art, in addition to the above-described method of making the outline thick, a method of coloring the entire part or the outline or displaying it in a shaded manner is also used.

[0013]

However, the above-mentioned prior art is unsatisfactory in that the part can be more easily found, and there is a problem that a method for enabling more efficient identification is strongly desired. As described above, especially in recent years, the number of mounted components has increased remarkably, and many components having the same appearance are often provided on a printed circuit board being displayed.

[0014] For this reason, the point that it is necessary to search for one component from a large number of components by using only the highlighting as in the prior art remains the same, and the above-described problem occurs. .

SUMMARY OF THE INVENTION It is an object of the present invention to provide a designated component display method in a printed circuit board design system in which the component can be easily identified from a large number of components.

[0016]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a designated component display method in a printed circuit board design system in which a printed circuit board is displayed on a screen and a mounting state of electronic components is confirmed. Thereby, the electronic component is displayed at the center of the screen.

The above object is also achieved by inputting the type of the electronic component in a designated component display method in a printed circuit board design system in which a printed circuit board is displayed on a screen and a mounting state of the electronic component is confirmed. It is also achieved that a plurality of electronic components of a type are sequentially displayed at the center of the screen.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a method for displaying designated parts according to the present invention will be described in detail with reference to the illustrated embodiments.
First, the embodiment of the present invention is also directed to a printed circuit board design system using CAD, which is the same as the prior art, and furthermore, if necessary, a designer inputs a command to the system, and Thus, as shown in FIG. 4, the image of the printed circuit board 1 is displayed on the monitor surface M in the same manner.

However, in the embodiment described hereafter, when the designer inputs the name of the part, that is, the part whose mounting state is to be checked into the system, the image shown in FIG. M differs greatly from the prior art in that it is configured to be displayed in M.

FIG. 1 shows a monitor surface M when the component name R1 in the table of FIG. 5 is input to the system.
When the designer inputs the part name R1, a cursor 2 consisting of a crosshair whose intersection coincides with the center of the monitor surface M is displayed from the state of FIG.

At the same time, the displayed printed circuit board 1 moves in the desired directions (up, down, left, and right) on the monitor surface M, and the image 3 of the component designated by the component name R1 that has just been input is displayed with the cursor 2 When the cursor comes to the center of the screen, the image 3 of the component having the component name R1 is finally displayed at the center of the monitor surface M, that is, at the center of the screen, as shown in FIG.
Displayed at the intersection of.

Further, in this embodiment, along with the above display, the X coordinate 4 and the Y coordinate 5 of the intersection of the cursor 2 are displayed at the lower part of the monitor surface M.

For this reason, in the printed circuit board design system to which the embodiment of the present invention is applied, the computer provided therein performs functions necessary for obtaining the display operation described with reference to FIG. And a memory that stores the parts list shown in FIG. 5 as a table together with the software.

This table uses a component name as search data (address), an X coordinate value and a Y coordinate value indicating a mounting position of the component as viewed from a coordinate origin 8 on the printed circuit board surface, an angle indicating a mounting attitude, and a mounting surface. Is tabulated so that the component mounting position is represented by the coordinates of the center point of the component, and the mounting orientation is such that the terminal arrangement direction on the component mounting surface is in the X direction. It is expressed as an angle.

This software is started in response to an input in a predetermined format from, for example, a keyboard or the like. First, the monitor screen M shown in FIG. 4 is displayed as an initial screen. Accordingly, FIG.
The processing required to display the monitor surface M shown in FIG.

Therefore, according to the embodiment in which the screen display shown in FIG. 1 is obtained, the designer inputs the part name of the part into the system by using, for example, a keyboard or the like, and then displays the contents among a large number of parts. There is no need to search for the part from, and it is sufficient to simply look at the intersection of the cursor 2 on the monitor surface M, and this alone can easily identify the part without any difficulty.

At this time, according to this embodiment,
As shown in FIG. 1, the X coordinate 4 and the Y coordinate 5 of the intersection of the cursor 2 are displayed at the lower part of the monitor surface M, so that the mounting coordinates from the origin of the part can be simultaneously and easily confirmed. be able to.

Next, another embodiment of the present invention will be described. The components to be mounted on the printed circuit board are set with a model, and are given model numbers and symbols, so that, for example, when mounting on a printed circuit board, the processing is managed according to this model. It is common.

Therefore, in the embodiment described below, with respect to parts of the same type, the cursor 2 is positioned at the center of the screen in a predetermined order, one by one, only by designating the part type, without individually designating the parts. Are displayed so as to coincide with the intersection of.

Now, the part with the part name R2 in FIG.
Assume that the components of No. 4 are of the same model, for example, the model symbol is HRXX. Then, in this embodiment, when the designer inputs the character string HRxx from the keyboard, first, as shown in FIG.
0 is displayed at the center of the screen at the intersection of the cursor 2.

Next, after a lapse of a predetermined time, for example, 10 seconds, or after a predetermined input operation, for example, operation of an execution key on a keyboard, as shown in FIG. The part 11 with the name R4 is displayed at the center of the screen so as to coincide with the intersection of the cursor 2.

Therefore, according to this embodiment, a plurality of components of the same type are displayed one by one in the center of the screen one by one as in the case of mounting the components on the printed circuit board. Also, it is possible to confirm the mounting state of the components.

In this case, the display order of the parts of the same type in this example is, in the above example, the order of the numbers in the part names from the smallest to the largest, that is, in ascending order, but there is no particular rule. Therefore, the order may be reversed in descending order, and of course, the order may be random.

[0034]

According to the present invention, it is only necessary to look at the part indicated by the cursor at the center of the display screen, and it is not necessary to find the necessary part from a large number of parts having the same appearance. Therefore, it is extremely easy to confirm the state of mounting components on the printed circuit board, and accurate verification of the printed circuit board design state can be performed easily and accurately in a short time.
