How to control the same net copper to via spacing while creating thermals in "No plane type" layer?
How to control the same net copper to via spacing while creating thermals in "No plane type" layer?
Can you give more detail on what PADS isn't doing? What are you trying to do?
i am just trying to get the values as described in the image
but when i set the via to copper clearance as 40 for this net , it is following the same value for the same net as well while creating thermals
I do not see if it would be possible without using Plane Layer and custom thermal pad definition.
Hello,
It looks like a Via that you want 40mil clearance belong to a different net. In Default Clearance rule keep clearance for Copper to Via as 10mil. Then select only the Net that other Via belong to and change clearance for that Net only for Copper to Via to be 40mil.
If all the items in your picture are indeed all belong to the same Net, follow Mr. Ershov suggestion from the earlier reply and use Plane Layer and custom thermal pad definition.

i just tried with split/mixed plane and it is working fine
Oh good, another plus for planes. I like learning something new. So far the only advantages I see for planes over pours are:
- You can remove unused pads on inner plane layers if you need to increase your copper on a plane.
- You can define antipads in your thermals instead of having to use the global clearance rules.
Ah, so you are trying to get a 10 mil antipad. How you do that depends upon which version of PADS you are running; it changed in 9.2. Search help for 'antipad', or hit help on the Pad Stacks dialog.
It's copper to via clearance rule
