Board Cutout within a Footprint Pad
« on: February 20, 2024, 03:29:28 pm »
Hi,

I am trying to make a footprint for a USB C connector from Hirose.
The part number is CX90B1-24P https://datasheet.lcsc.com/lcsc/2111232030_HRS-Hirose-CX90B1-24P_C597821.pdf.

This connector has a weirdly shaped pad as shown in the following picture

I made a pad from a custom shape and placed board cutout inside.


But it doesnt work. The DRC shows a clearance issue with the board edge (although I tried exclude it with "not InBoardCutoutRegion")
and the pad itself has no cutout.
2026004-2

Any suggestions how to fix this or is it possible to create a cutout for a pad?
Thx Martin

You can place slot holes in a pad, if you change the hole shape. L shaped hole...  :palm:
Maybe two pads on top of each other?
When you think your software supports everything, connector manufacturers invent new problems...
Honestly, if it was up to me, I would just select a different part number and tell Hirose about it.
Also every connector footprint is simultaneously under and over defined in dimensions. The ones that you need are never there, but its filled with repeated info.

I switched to a connector with a more common and easier footprint.

At first I thought it has to be possible to create such a footprint.
