Hello,
I have a 2x5 pitch 1.27mm pin header connector.
Both the SFH and FTSH series of samtec can fit.
I have the footprint for both series
On PCB I would like to overlap them in this way:
but then I have a lot of DRC errors. I would not like to disable such checks. How can I solve this? Is there a footprint property for this?
best regards
Max
Either put up with the errors, or exclude each error that is not a real issue.
I have a board that has a lot of these errors, because I have SMT resistors under a through-hole socket.
If you right-click on the error you can “exclude” it.
You can’t put both footprints on the PCB at the same time, so why do you want both?
Pad layout seems to be exactly the same for those two variants. I would probably copy the biggest into a custom library, give it the name FTSH_SHF and then add some extra silkscreen for the smaller variant. That name will show up on the BOM, and during part ordering you can decide what you want to buy.
If you also want two schematic symbols, you can put them on top of each other. That makes both symbols connect to the same wires in the schematic, and the DRC errors go away. (At least for the connections, but not for the yourtyard. But whatever you do, pay attention to details. Even the glue dots can be a manufacturing reliability headache.
You could also create a new footprint in a personal library by copy/paste both footprints into the new footprint (as your 3rd picture) then delete the redundant 10 pads, text and graphics.
