IPC Compliant Footprint Wizard

Modified by Phil Loughhead on Jun 19, 2017

The IPC Compliant Footprint Wizard creates IPC-compliant component footprints. Rather than working from footprint dimensions, the IPC Compliant Footprint Wizard uses dimensional information from the component itself in accordance with the standards released by the IPC.

Rather than requiring you to enter the properties of the pads and tracks that are used to define the footprint, the Wizard takes the actual component dimensions as its inputs. Based on the formulas developed for the IPC-7351 standard, the Wizard then generates the footprint using standard Altium Designer objects, such as pads and tracks.

For more information about creating component footprints, see the Creating the PCB Footprint page.

This dialog is compliant with Revision B of the IPC standard 7351 - Generic Requirements for Surface Mount Design and Land Pattern Standard. IPC-7351B was released in 2010 and supersedes IPC-7351A (which was released in 2007).

Accessing the IPC Compliant Footprint Wizard

The IPC Compliant Footprint Wizard is launched by clicking Tools » IPC Compliant Footprint Wizard from a PCB Library document.

The dialog can only be accessed if the IPC Footprint Generator extension is installed as part of your Altium Designer installation. This extension is installed by default, but if it is inadvertently uninstalled, the extension can be found on the Purchased tab of the Extensions & Updates page (DXP » Extensions and Updates). 

Hover over the icon and click  to download the extension. Altium Designer must be restarted to complete installation. 

If at any time you want to uninstall the extension, find the extension on the Installed tab of the Extensions & Updates page (DXP » Extensions and Updates) and click the  icon to uninstall. Altium Designer must be restarted to complete the uninstall process. 

Wizard Navigation

  • Click Cancel to close the IPC Compliant Footprint Wizard.
  • Click Back to navigate to the previous screen.
  • Click Next to navigate to the next screen.
  • Click Finish to close the IPC Compliant Footprint Wizard
Finish is available on any page of the Wizard after selecting the component type. If you click Finish before completing the entire Wizard, the footprint will be created using the system defaults for the component type you selected.

Selecting the Component Type

Choose the family of components for which you want to create a footprint on the Select Component Type page.

Click on the component type desired. The preview region on the right-hand side of the Wizard dynamically changes to show the currently selected component and also states the type of packages that are allowed to be generated.

The following table lists the component types and packages that are supported in the Wizard.

Tips

  • Paste Masks are split into small fills for packages with a large thermal pad (sized 2.1mm x 1.6mm, or larger).
  • For packages involving gullwing leads, pads are trimmed to prevent them from otherwise extending under the package's body.
  • For small packages having a large central thermal pad, the peripheral pads are trimmed to ensure required clearance between the pads in accordance with the IPC Standard.
  • When pad trimming is applied, a warning is displayed within the dialog.

Preview Region

On the following pages for each component type, the Preview region dynamically updates to show new location, size, etc., for several settings. 
 
In the Preview region, you can click  to toggle between 2D and 3D preview images. Click the icon then select 2D or 3D, whichever is appropriate. If the current image is 3D, click the icon to further define the preview by selecting/deselecting Show Simple 3D Bodies and Show Generic Models.
 

3D STEP Models

Previewing 3D STEP Models

If desired, you can see a preview of the 3D STEP model before generating the model. Click Generate STEP Model Preview on any page in the Wizard after selecting the component type to see a preview of the 3D STEP model in the Preview region.

The default setting for the files that are created when 3D STEP models are generated is Embedded STEP files. If these default settings are correct for your needs, you can click Finish to exit the IPC® Compliant Footprint Wizard and generate the 3D STEP model.

The subsequent pages of the Wizard change depending upon the component type you selected. Find your component type in the following list and click on the link to access the information regarding that component type.
