Per net SMD-SMD clearance

[silvio3105]

Hi,

I have antenna/RF trace and I want to set SMD-SMD(or copper to copper) clearance for only that trace. Not sure how to do it. I put all RF traces/wires in same net class. Now, how to change clearance? Thanks.

Hi @silvio3105,

If I understand correctly what you want to do then creating a custom Same Signal Copper Clearance rule might help. You can target a specific signal and you can specifiy that this rule should apply to SMD pads only for example. You can change to other objects but keep in mind that because this is same-signal copper clearance you cannot have traces that are connected because that would violate. Here is a starting example:

Please let me know if there is anythign else I can help you with regarding the custom design rules.

Kind Regards,
