I'm a student trying to create a library part in Altium for an Analog Devices AD8232. Most IC datasheets give a recommended footprint to use, but the AD8232 datasheet only shows the IC itself:

enter image description here

I have been searching, but have been unable to find a recommended layout for this footprint.

If you were designing the footprint for this device, how would you determine the pad sizes to use?


Method #1:

Tools->IPC Footprint Wizard->QFN and go from there.

This wizard is based on IPC-7351 standard, the main standard for footprint creation. The standard is not straightforward if you want to calculate the footprint dimension by your own so it´s highly recommended to use the wizard.

Method #2:

Refer to AN-772. A Design and Manufacturing Guide for the Lead Frame Chip Scale Package (LFCSP)
