70 Components and Constraints Page 78 This task explains how to manage components given the component constraint type. This feature is available on both the board and the manufacturing panel. Open the Scenario3.idf file and the corresponding Scenario3.lib file from the samples folder. An Assembly Product document is generated. If the configuration you are using provides access to the Assembly Design workbench, geometrical constraints are created between the board and the components, and are displayed. Within the assembly, the board needs to be anchored.

71 Page Double-click the power-jack constraint shown here in red. The Constraint Definition dialog box opens. The Assembly constraints (geometrical constraints) linking the components to the board depend on the component status. Component Status Unplaced Placed Fixed Assembly Constraint No Constraint Plane to Plane Constraint Fixity Constraint This information is transmitted through the import file (.idf), the component capability to change location is then driven by the constraint. Under certain circumstances, a component status can be modified: from unplaced to placed or fixed from placed to fixed but never from fixed to placed or unplaced, nor from placed to unplaced (in order to keep the information defined in the ECAD world).

72 Page Editing the constraint, using the More>> button, lets you modify the offset between the component and the board (IDF 3.0): The IDF 3.0 takes into account the offset which represents a mounting constraint of the component onto the board. The offset is also managed between the board and the panel.

The panel file contains the physical description of the manufacturing panel and the location of the boards and components on that panel. It can be created interactively then exported. 2. Annotations: a new section is added to the file. It contains notes for the design that can be displayed to allow the electrical and mechanical designers to communicate additional information about the design entities. They are not intended for manufacturing purpose. At the moment, they can only be modified in CATIA then exported. 3. Offset: the offset field represents the mounting offset for a component onto the board. It is also available for board mounting offset onto the panel. Placing a component creates a constraint. Editing the constraint allows you to modify the offset. It will be taken into account in the export file. 4. Properties: an optional record specifies properties for the component such as capacitance, resistance, tolerance, power_max, etc. as well as user defined attributes. You can set the values in the Properties dialog box. Your changes will be taken into account in the export file.

97 Importing Using a Catalog Page 105 This task explains how to import data from an IDF file, where the component 3D geometry is imported from a catalog. This feature is available for both the board and the manufacturing panel. 1. Open the Import.idf document from the sample directory. The.idf file contains the location of the components in the circuit board assembly. You can use a library and/or a catalog to get a better geometry of the components: the.lib file contains the 2D footprint geometry of the components. the.catalog contains the 3D (exact) geometry of the components. However, none of these files are mandatory. You can choose between several alternatives: open a library only: the 3D geometry is extruded from the 2D geometry open a library and use an existing catalog: the component exists in the catalog, its 3D geometry is imported from the catalog the component does not exist in the catalog, it is extruded from the 2D geometry and stored in the catalog if the catalog is not protected (Catalog in read/write mode box is not checked) open a library and a new catalog: the 3D geometry is extruded from the 2D geometry and stored in the newly created catalog open no library, but a catalog: the component exists in the catalog, its 3D geometry is imported from the catalog the component does not exist in the catalog, it is created with no associated geometry open neither library nor catalog, the component has no associated geometry. The Circuit Board Design dialog box opens. The first light is green: the selection is valid. The second light is yellow: you can choose a library (optional).

98 Note: If no components are available in the idf file, the light does not show any color. Page Browse using the button and select the ImportComps.lib file. The light turns green. 3. Click to activate the third light: it turns yellow and the catalog options become available. The Catalog in read/write mode option preserves your catalog from overwriting. Associate a csv file to catalog allows you to select a mapping table (csv format): the matrix gives the equivalence between the ECAD and MCAD references. Note: If no components are available in the idf file, the light is disabled (no color). 4. Browse using the button and select the Import.catalog file. The light becomes green. 5. Click OK to validate. The Status bar indicates the progression. The import is completed. Note that if you have set a catalog in the Options, it will be proposed by default.

99 Catalog Page 107 This task explains how to insert a component into a document from a catalog. The integration with the Catalog workbench lets you have access to the advanced catalog capabilities such as the component drag and drop. For more information about Catalogs, refer to CATIA - Infrastructure User's Guide. 1. Open a catalog using Start -> Infrastructure -> Catalog Editor and choose the Preview tab. 2. Open a new CATProduct document. 3. Tile the windows horizontally. It looks like this: 4. Select the components you want to insert into the CATProduct. 5. Drag and drop it onto the Product. An alternative is to copy then paste it (Ctrl-c then Ctrl-v) The components are copied in the CATProduct document

100 Using a CSV File Page 108 Most of the time, the component position on the board and its part number have origin coordinates and references which are different according to the environment taken into account (ECAD or MCAD). To import or export data respecting the original environment, it is possible to use a csv (comma delimited-like format) file together with a catalog. The default column separator used by CBD for csv files is the semi-colon ";". A line in the CSV file is made up of a pair "keyword - value" separated by semi-colons. The csv file contains a positioning matrix drawing up the mapping between the mechanical and electrical references: the matrix defines the translation on dx and dy as well as the rotation teta around dz axis to be applied to the catalog component. Let's see an example: package name;resistor: corresponds to the package number of the MCAD component. part number;res11: corresponds to the part number of the MCAD component. dx;10: indicates a translation to the x axis direction. dy;10: indicates a translation to the y axis direction. dz;0: indicates a translation to the z axis direction. teta;30: indicates a rotation around the z axis. package name;resistorelec: corresponds to the package number of the respective ECAD component. part number;res11elec: corresponds to the part number of the ECAD component. The component references (part number and package number) can also be different and are stored in the csv file. When a csv file has been used for import, this option is stored in the temporary user settings. If you export your data again, the option will be checked.
