No Connects to Mounting Pads

Layout
1

Hi,

I am using a footprint which has 2 mounting pads. I’ve selected a symbol which contains “mounting pins” (Connector_Generic_MountingPin:Conn_01x04_MountingPin) and set the mounting pin to no connect

However, in the layout, there remains a rats-nest connection between the MP pads:

Does anyone know if its posible to set pads to be no connect/mounting pads? Do I need to use a different footprint with different pads associated with each separate mounting pad?

I’ve recently updated to V7.0.2 and I don’t remember this behaviour before.

According to the explanation in gitlab-issue 13234 (PcbNew 6.99: Multiple footprint pads with the same pad number whose symbol pin(s) are marked as unconnected raise a DRC error regardless (#13234) · Issues · KiCad / KiCad Source Code / kicad · GitLab) this behaviour is as designed:

“At the moment, KiCad assumes all pads with the same name have to be connected together.”

So you need a footprint with two different MP-pads (MP1/MP2) and a suitable symbol with 2 mounting-pins.

my solution for such cases:

  • either ignoer the remaining ratsnest-line (with a note written on the user.comments layer.)
  • or more often: such connectors are mostly used at the edge of the board. Normally there is plenty of space to simply draw a small track through the GND-zone fill beneath the connector.

Ignoring the ratsnest does no harm.
In this case, it is normal to connect those pads to a ground, as they are the connector shield and are required for EMC compliance tests to pass
