1. Click PCB and then, in the Assembly group, click New. The Create PCA dialog box opens.
2. Specify the name and the owner of the PCB assembly. If you want the assembly to belong to the top-level parent (root), type / for the owner.
3. Click .
4. Add the required profiles to the PCB assembly.
5. Add the parts you want to include in the assembly.
6. Update the PCB assembly to visualize the result of your additions.
7. When you are finished, you can export the PCB assembly.
To update a PCB assembly,
When you have added profiles and parts to your PCB assembly, use Update to apply these additions and changes to the PCB assembly. For instance, Update punches the cutout defined by a BOARD-CUTOUT type profile.
Proceed as follows to update a PCB assembly:
1. Click PCB and then, in the Assembly group, click Update. The Update PCA dialog box opens.
2. Click PCA and select the PCB assembly to update.
By default, the active PCB assembly is selected.
3. To change the thickness of the PCB assembly, click ChngThick in the Modify Board Thickness section and type the thickness in the PCBThick box. The placement of any parts located on the board will be adjusted automatically. For instance, if the board becomes thicker, the parts on the "rising" face of the board are raised with that face.
4. To punch holes based on profiles from one or any combination of the following sources:
◦ Part: holes are punched based on profiles included in a part.
◦ Model: holes are punched based on profiles included in a model.
◦ Board: holes are punched based on profiles included in a board.
5. To specify a punch profile, click ProfSet and select a profile from the Punch Profile Table. You can activate or deactivate a punch profile by a single click in the desired cell of the punch profile table.
6. Click to finish the operation.
An update operation on the PCB assembly moves the profiles, derived objects and the parts to their correct position with respect to the board part. The correct position of the board outline is at half of the board thickness.
Attempting to Update a named PCB assembly with no board outline profile will generate an error.
To use the Punch Profile table,
The Punch Profile Table is displayed by clicking ProfSet enables you to create an activation matrix for profiles to be included in the PCB assembly update.
For example, if you want to update the models to see only the model related mounting holes and not the model related pins, you can do the following:
1. Click PCB and then, in the Assembly group, click Update. The Update PCA dialog box opens.
2. Click Model to enable the model holes.
3. Click ProfSet to open the Punch Profile Table.
4. In the model column of the Punch Profile Table, disable the Drilled-Holes-Pin and enable the Drilled-Holes-Mtg.
5. Click in the Update PCA dialog box to Update the PCB assembly to view the change.
During the PCB assembly update, the Active settings are applied only to the clicked check boxes. For example, if a profile is set to Active for Part although the Part check box is cleared, the Active setting will be ignored during the update.
To move a PCB assembly by workplane,
Use Move by WP to move a PCB assembly by first moving an individual profile workplane of the PCB assembly. When you confirm the move by selecting OK, the rest of the PCB assembly is moved.
The Move by WP command uses the same functionality as the Position command on the Creo Elements/Direct Modeling Structure tab (in the Part & Assembly group). You can use this command when it seems easier to move or align one of the constituent profile workplanes to establish the final location of the PCB assembly, rather than to move the model of the PCB assembly (as you would with the regular Creo Elements/Direct Modeling Move command).
Proceed as follows to move a PCB assembly by its workplane:
1. Click PCB and then, in the Assembly group, click Move by WP. The Move by Profile dialog box opens.
2. Specify or select the profile whose workplane you want to move.
3. Use the functions provided in the Move by Profile dialog box to move the workplane of this profile.
4. Click . The PCA follows its workplane.
You can move a PCB assembly using the Creo Elements/Direct Modeling positioning commands. To do so, you must select the entire PCB assembly.
To change the PCA origin,
Use Modify Origin (click PCB and then, in the Assembly group, click Modify Origin) to change the origin of a PCA assembly within the same workplane. To do so, you need the distance along the x-axis and the y-axis. Proceed as follows:
1. Select the PCB assembly whose origin you want to change. By default, the current PCB assembly is selected. If you want to change the origin of a PCB assembly other than the current one, click PCA in the Move PCA Ori dialog box select the assembly from the Structure Browser.
2. Specify the X component of the move vector for the origin.
3. Specify the Y component of the move vector for the origin.
To delete a PCB item,
Use Delete to remove an item from a PCB assembly. To delete an item from the PCB assembly:
1. Click PCB and then, in the Assembly group, click Delete. The Remove dialog box opens. This item can be one of the following:
◦ a PCB assembly
◦ a part
◦ a model (only if the model is not shared by any other part)
New. The Create PCA dialog box opens.
