Part Audit Review

Yes, correct the pin mapping, pin types, descriptions, metadata, and exposed-pad paste strategy.

flux

I’ll correct the symbol’s pin assignments and metadata from the datasheet, then revise the exposed-pad paste into a segmented manufacturable pattern and verify the resulting symbol and footprint.

flux

The symbol and metadata corrections are in place. The footprint API cannot safely create independent paste-only windows, so I preserved the exposed-pad copper and applied a centered paste reduction giving about 60.5% coverage; I’m now performing the final read-back verification.

flux

Corrected the pin 41–43 mapping, pin 50 label, all 77 pin types/descriptions, and part metadata. Pad 77 retains its 6.06 × 6.56 mm copper land with a reduced 4.66 × 5.16 mm paste aperture (~60.5% coverage); true window-pane segmentation is not safely supported by the current footprint API.
Verification confirmed 77 unique pins and 77 footprint pads. Details are recorded in the updated Part Audit Report.
