The Create Stackup form is opened.
2. Specify a name for the stackup.
A default name for the stackup is displayed, but this name is not very descriptive. The name should
be simple, yet descriptive of the stackup. In this example we are creating the flex stackup defintion,
a name like "Flex_Main" would indicate that the structure is for the flex portion of the design, and
this would be the common structure for any flexible areas in the design.
3. Select the layers in the stackup.
The layers that currently exist in the stackup can be assigned by default, or exluded by default by
selecting one of the three option buttons in the Create stackup form. The same structure of another
stackup may be copied, and then modified after creation to meet the new definition requirements.
For this step, the exclude layers option is selected.
4. Click the OK button.
