Via Stitching - Best Practice
« on: February 11, 2017, 08:07:47 AM »
Hello,
how do you do via stitching in KiCad?
I don't need a huge amount of vias, just connect top and bottom plane together.
It seems there are two ways:
  • Creating a footprint just containing a via
  • drawing traces with vias all over the board

They both seem to make the board cluttered and don't seem to work with the remove unused track/footprints option on netlist import.

What is your workflow? What is the best way?

I use a separate single-pad footprint, usually tied to the GND net, that can be copied one-by-one or with the grid-copy tool. Together with GND filled zones it works ok.
I don't know if there's a solution to the remove-unused-footprints issue (i.e. since the stiching vias are not in the schematic/netlist you can't use remove-unused-footprints or your stiching vias will disappear).

Doesn't that mean you won't be able to tent the vias unless you cover it in the footprint?

right. I think you could create a separate tented-via footprint and use that?
Some solution where the manually inserted via-footprint won't disappear during a netlist-update (that updates/adds/removes regular footprints) would be good.
