i'm trying to create an airtight soldered mount for a pipe on a pcb depth sensor board I'm designing. To do this I am trying to create a custom pad in Altium that is a ring and is also plated. I've tried converting the ring to polygons, regions and cutouts. I've not been able to get any of them to become plated.enter image description here

The picture might make this easier to understand. I want to put a plated ring of some sort in the empty ring as seen above.

    \$\begingroup\$ You can just copy your ring, and then paste it onto the solder paste layer (Change to paste layer, select Paste Special...On Current Layer). \$\endgroup\$ – The Photon Jul 5 '16 at 16:00

Why not simply place a full circle (p->u), set the thickness to your desired fitness and the solder mask to 0. The ring will be plated and no soldermask on top.

  • \$\begingroup\$ Thanks for the answer, I ended up just changing the solder mask expansion to "from rule" instead of "none" and verified that the ring was plated by viewing the gerber file. \$\endgroup\$ – n4alpaca Jul 5 '16 at 21:50
