The Footprint Expert uses the following standards / guidelines:

IPC-7352 - Mathematical model for pad stack calculation
IPC J-STD-001 - Solder joint goals for Toe, Heel and Side
IEC_61188-7 - Zero Component Orientation
FED Vol 18 - Proportional Land Dimensioning Concept

The Footprint Expert uses these standards by default, however these and dozens of other options may be easily configured to build entire libraries to your own CUSTOM requirements! Any parts previously built/saved in the Footprint Expert neutral format can be rebuilt to any CAD format, with any modified setting.

Default rotation? Change setting, batch-build!
New tolerance? Change setting, batch-build!
Different pad shapes? Line widths? etc... No problem!
Modify the Naming Conventions? done!!
Any of these updates, plus many more for your entire library? Just click "Build"!!!


Footprint Expert supports 5 Footprint Naming Conventions:
  • IPC-7351B
  • IPC-7352
  • PCB Libraries (IPC-7351C)
  • MfrName_MfrCaseCode (Non-standard Packages)
  • Your Custom Footprint Name 
You can test them in the Calculator > Design Options > Footprint and Pad Stack Naming.

Example:

QFN w/Thermal Pad
PCB Libraries (IPC-7351C) = QFN29P50_500X400X80L40X25T355X255
IPC-7351B = QFN50P500X400X80-29
IPC-7352 = QFN50P500X400X80-29T355X255
