No mask on vias


#1

I add vias simply by “Add vias” button. Not by creating a separate footprint for it. I noticed that I can’t add these vias to mask layer. Is it possible or I need to create custom footprint?
Kicad 5.0.0


#2

Tenting vias or not is an option in the plot output settings dialog.


#3

Thanks! But in pcbnew vias always don’t have soldermask?


#4

Or they always have. The option when generating the Gerber files is “Do not tent vias”.

It is not a decision you have to make while routing, only when plotting as Efcis said.


#5

Now, of course, this means that KiCad doesn’t support having some vias tented and others not without going through some logistical gymnastics. Essentially if you only want a few vias not tented you would have to use a via-sized single pin THT part instead of the via (and may as well call it a test point once you are doing that).


#6

I’ve requested this feature in Kicad bug tracker https://bugs.launchpad.net/kicad/+bug/1778887 It seems to be targeted for V6.

Currently my workaround is to use normal vias and add solder mask clearance with graphic circle on needed mask layer. I do this as final step of layout. In my case only minority of vias need mask removed.
