The investigation unit 32 is activated by the operator, investigates the data of the electronic component desired by the operator from the component data recording unit 31, and after discovering the component data desired by the operator,
The survey data storage unit 33 is activated. Survey data storage unit 3
3 stores the component data investigated by the investigation unit 32. The shape data extracting unit 34 activates the shape data storage unit 35 after extracting the shape data of the parts necessary for determining the part layout from the part data stored in the survey data storage unit 33. The shape data storage unit 35
The shape data extracted by the shape data extraction unit 34 is stored together with the part name. The shape sample creation unit 36 creates a component shape sample required for component mounting layout based on the shape data of the component stored in the shape data storage unit 35, and then activates the shape sample storage unit 37. The shape sample storage unit 37 stores the shape sample created by the shape sample creation unit 36. The layout determination unit 38 determines the component mounting layout by performing a layout study based on the board size and the case size specified by the operator and the shape sample stored in the shape sample storage unit 37.

In this conventional component layout support device, the operator activates the survey section 32 to survey the component data to be mounted, and specifies the desired component group name and component name. Thereby, the investigation unit 32 investigates the component data recorded in the component data recording unit 31. When a component desired by the operator is found in the component data recording unit 31, the survey unit 32 causes the survey data storage unit 3 to operate.
3 stores the component data of the survey result. Next, the operator activates the shape data extraction unit 34 in order to extract the shape data of the component, which is necessary when considering the component mounting layout, from the component data of the survey data storage unit 33. As a result, the shape data extraction unit 34 extracts the shape data of the component stored in the survey data storage unit 33 from each component data while associating with the component name and stores the extracted shape data. Storage unit 35
To start. As a result, the shape data storage unit 35 stores the shape data extracted by the shape data extraction unit 34 together with the part name. Next, the operator activates the shape sample creating unit 36 to create a shape sample so that the shape samples can be actually arranged when the component layout is examined. The shape sample storage unit 37 stores the shape sample created by the shape sample creation unit 36. Next, the operator activates the layout determination unit 38, and causes the shape sample stored in the shape sample storage unit 37 to determine the component mounting layout so that the layout can be performed on the specified board size and enclosure size. ..

The operation will be described more specifically. When the content of the component data recording unit 31 is as shown in FIG. 7, the operator inputs the component name A to the research unit 32 in order to create a shape sample of the component A (VRAM01-ZIP), for example. As a result, the survey unit 32 reads the component data of the component name A from the component data recording unit 31 and stores it in the survey data storage unit 33 as shown in FIG. The shape data extraction unit 34 extracts shape data from the contents stored in the survey data storage unit 33 and stores it in the shape data storage unit 35 as shown in FIG. The shape sample creation unit 36 creates a shape sample from the contents stored in the shape data storage unit 35, and as shown in FIG.
Save the shape sample to. The operator repeats the input of the component name to the investigation unit 32 in order to create a shape sample necessary for performing the component mounting layout. For the shape sample of the same part, the shape sample creation unit 36 creates a shape sample by repeatedly performing the operation of creating a shape sample from the content stored in the shape data storage unit 35 and storing it in the shape sample storage unit 37. To do. With the shape sample thus created, the layout determination unit 38 performs component mounting layout according to an instruction from the operator.

As described above, in the conventional component layout support apparatus, as shown in FIG. 11, one allocated storage area is required for one operator. Therefore, when a plurality of (n names) operators try to perform a component layout, the result is as shown in FIG. 12 or 13. That is, FIG.
When the operators 1 to n (n ≧ 2) sequentially perform the component layout using the component layout support device as in No. 2, the operator 1 inputs the component name into the investigation unit 32 and creates it by the component layout support device. Parts are laid out by the sample of the shape. Similarly, operator m

Further, as shown in FIG. 13, operators 1 to n (n
Operators 1 to n (n ≧ 2) when ≧ 2) performs component layout using the component layout support device at the same time.
However, the component layout is simultaneously performed with respect to the component layout support device including a plurality of the survey data storage unit 33, the shape data storage unit 35, and the shape sample storage unit 37. That is, the operator 1 inputs the component name into the investigation unit 32 and performs the component layout using the shape sample created by the component layout support device. Similarly, the operator m (m ≦
In n), the operator inputs the part name to the investigation unit 32 at the same time as the operator 1, and performs the part layout using the shape sample created by the part layout support device.

Next, the operation of the component layout support apparatus will be described more specifically by taking the case of constructing a memory system on a substrate having a prescribed shape as an example. It should be noted that all component shapes are rectangular parallelepipeds. Now, assuming that the layout determining unit 6 stores the component name input by the operator into the input device 9 in the component list storage unit 3 as shown in FIG. 2, the shape sample creating unit 4 causes the component data managing unit 2 to operate. The component data storage unit 1 storing the component data as shown in FIG. 3 is searched for the component data according to the component name in the component list as shown in FIG. 2 stored in the component list storage unit 3. .. And the shape sample creation unit 4
Is created by creating shape sample data (the coordinates of each vertex of the rectangular parallelepiped are the shape sample data) based on the shape data of the part obtained from the part data storage unit 1 and activating the shape sample storage unit 5. Figure 4 shows the shape sample data
The shape sample storage unit 5 stores it as follows. As a result, the layout determination unit 6 causes the output device 10 to output the component shape based on the shape sample data via the output management unit 8. The operator operates the input device 9 to input an instruction regarding the component layout. That is, the operator visually examines the component mounting layout using the input device 9 and the output device 10.

Next, as shown in FIG. 5, by using the component layout support apparatus of this embodiment, the component data storage unit 1 storing the component data is shared by a plurality of operators to efficiently study the component mounting layout. The case of performing will be described. Now, it is assumed that n operators are studying the component mounting layout, and a certain operator is working using the input device 9 and the output device 10 connected to the communication line. The operator's instruction input to the input management unit 7 via the input device 9 is managed by the input management unit 7 without being confused with the instructions of other operators, and the component data management unit 2 and the component list storage unit 3 are connected to each other. It is passed to the layout determining unit 6. The name of this component is the layout determination unit 6
Thus, the data is stored in the parts list storage unit 3 for each operator's input. Then, the layout determination unit 6 activates the component data management unit 2 and applies the component data stored in the component data storage unit 1 based on the component list for each operator stored in the component list storage unit 3. Search for part data. Then, the shape sample creation unit 4 creates shape sample data based on the shape data of the searched part data, and stores the shape sample data in the shape sample storage unit 5 for each parts list (for each operator). Then, the layout determination unit 6 causes the output device 10 of each operator to output the shape sample based on the shape sample data stored in the shape sample storage unit 5 via the output management unit 8. Each operator operates the input device 9 while referring to the shape sample output to the output device 10 to perform component layout.

In this way, a parts list is created for each operator, shape data can be extracted from the part data without operator intervention by the parts list, and shape sample data is created and stored from the shape data. Therefore, compared to the conventional component layout support device,
The storage area can be reduced. Further, since the input management unit 7 and the output management unit 8 manage the operation of the input device 9 and the output device 10 connected to the communication line, it is possible to effectively use the component data among many operators who are distant from each other. You can

The shape sample storage unit and the name of the component to be laid out are stored in the component list storage unit and stored in the shape sample storage unit. Since the determination of the component layout on the basis of the shape sample data provided a layout determining section for performing interactively with the operator, since only by specifying the part name can create the shape of the part sample, it can be reduced operator intervention. Further, even when used by a plurality of operators, there is an excellent effect that the mounting layout of components can be efficiently supported without requiring a large storage area.
