IPC Compliant Footprints Batch Generator

Modified by Susan Riege on Feb 8, 2019

The IPC ® Footprints Batch generator dialog

Summary

This dialog allows you to generate footprint packages in PCB library files (*.PcbLib) from input files that can be Excel workbooks or comma delimited files.  

For more information about creating a component Footprint, 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).

Access

The IPC® Footprints Batch generator dialog is accessed by clicking Tools » IPC Compliant Footprints Batch generator from a PCB Library file (*.PcbLib).

The dialog can only be accessed if the IPC Footprint Generator extension is installed as part of your Altium NEXUS 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. 

Hover over the icon and click  to download the extension. Altium NEXUS 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 and click the  icon to uninstall. Altium NEXUS must be restarted to complete the uninstall process.

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 (PQFP, QFN, SOIC, and SOP), the peripheral pads are trimmed to ensure required clearance between the pads in accordance with the IPC Standard.
  • IPC footprints are always generated in metric units.
