Trouble with pads

I hereby certify that I am not simply asking someone else to design a footprint for me.

This is an auto-generated message that is in place on the “footprints” section of the KiCad.info forum. If I remove it and ask for a footprint to be designed anyway, I understand that I will be subject to forum members telling me to go design my own footprint or referring me to a 3rd party footprint site.

Kicad version: 9.0.5

When I create a through-hole circular pad in a footprint, the copper ring on the top side is covered by solder paste (I can confirm this by turning the solder paste off in 3D view) and the ring on the bottom side is not visible. I suspect that it is there, but covered by solder mask.

What I expect is a TH pad with a blank copper ring on both sides. What am I doing wrong?

The upper pad is the (bad) one I created using the footprint editor. The lower pad is one I copied from an existing footprint of a pinheader.

Pads have some options to be set (layers which they should also have). Can’t be more precision as I have no KiCad here.

Did you create it as a SMD type pad ?

@RaptorUK look at the screenshots of the 3D model :wink:

PS: the inital default pd is a rectangular SMD pad. I then change it to a trough-hole round pad.

@Piotr I know. I compared the properties of the pad I created with those of the pad I copied from another footprint. didn’t see any difference. Maybe (probably) I’m missing something…

Attached is the test foorprint which contains the one I created and the one I copied from another footprint. I place them directly in the PCB editor (don’t use the schematic editor) and then look at the result in the 3D viewer.

So you created a SMD pad (which has a default solder paste layer) and then change the shape to a through hole pad . . . and then expect it not to have solder paste ? why would you expect that ?

If you want a through hole pad, create a through hole pad.

The SMD pad is the default (at least in my setting) when I add a pad. I have to take it from there.

Meanwhile I found the solution to my problem. Once the pad is on the PCB change it to the desired pad type (in my case a circular TH pad), right-click on the pad and apply the ‘default properties.

Now the pad looks like it should be: copper exposed on both sides of the PCB.

What is your footprint “Component type” ? Through hole or SMD ? the default pad type changes to match . . .

Yes. You’re right. That does the job too. Thanks for pointing this out.
