Donut Pad to Ground Connection

rmerrill

I am using the Pad Editor in Ver. 17.2-2016 S011 at the moment.

I am trying to create a Pad Stack for a Non-Plated Mounting Hole that has a Donut Pad on the Outer Layers to connect to Ground.

Chassis Ground are on Internal Layers so, within the Board, I will be placing a Via and then adding a Trace to the Copper Donut Pad.

Once I define the Outer Layers as a Donut, the Usage Options at the bottom the Summary Page adds "Enable connect by touch: No"

As I seem to need to use Touch, to connect it to a via, without a DRC violation, I am expecting that this should say "Yes".

    One thought is to define the Donut Pad padstack as Plated and enable smaller multiple drills that land inside of the donut pad boundary which would connect to the internal plane layers.  All you would need is to place a separate non-plated drill padstack in the middle of the Donut Pad padstack.  It could be done all in the same package symbol with the Donut Pad connection driven by the netlist.

    Hope this help,
