Can someone help me with this power-plane problem please?
I am attempting to make this replacement PCB for a Solartron Digital Voltmeter because the original is in too poor condition to repair.
It is a four-layer PCB with the internal layers used for +5V, which has the net designation "+5VE" (from the original circuit diagram) and "0VE" for the earthy plane 0V (again from the original circuit diagram).
When I click "Regenerate Power Plane" I get the power-planes covering the entire workspace instead of ending 0-3" inside the board edge!
What am I doing wrong here, and could I redesignate the power planes as "Copper Pour Areas", or aren't Copper Pour Areas meant to be used this way?
Would it make the PCB un-manufacturable if I tried to re-designate the Power Planes as Copper Pour Areas?

I'll give that a try – it'll almost certainly solve the issue!

Posted - 01 Feb 2023 : 15:17:37 Don't use Power Planes, use normal (mixed signal) internal layers and then create a copper pour area for the internal power planes. Far less agro!
Edit. The pcb edge to flood area distance is determined in Design Tech =>Spacings Table regardless of Copper Pour or Power Plane useage. |
