Electrical – Leave tracks on solder layer – Altium


I want to create a PCB with some traces on the solder layer, so I can reinforce them with tin.

Those traces will use AC current and about 5 amps. So I want to create some traces with 3mm wide and tin above.

I just see options to create traces on top layer and bottom layer. How can I create a rule to create those traces on solder layer? I am not sure which layer I need to choose neither.

If you want to remove solder mask above the trace, just select all the segments of the trace and use PCB inspector to set the Solder Mask Expantion Mode to From Rule.

If you're not fussy about how the paste is added, you can also define paste expansion in the same place.
