Kiernan,
>I'm still on my first PCB under P99SE. I need to add quite a few extra routes, >but the PCB is really dense. Can I route these on the InternalPlane layers? As the following text shows that you are talking about plane layers, I would strongly discourage you to do so, though it technically is possible. Seperated planes, especially ground planes, are a cause for trouble. If you absolutely have to place traces on them, take a 5V, 3.3V, etc. power plane for this purpose, but never a GND plane! >Should I have used Polygon pours on ordinary layers instead? I would do that. >If I am allowed to use the plane layers, then how can I tell whether I'm going to isolate some >connections from others ERC should tell you that. I never tried such a design myself, though. But ERC works fine with split planes. >and how can I clean up where the trace ploughing would >leave nasty slices / lost copper? You must keep in mind that power layers are negativ layers. You can place fills and polygons on planes, which result in no copper for these areas. >Also on plane layers can I pull the plane completely away from a particular area? Use fills, tracks, polygons, whatever you like and place them ther, where you want _no_ copper. >And finally, if I use a polygon on a normal layer, then how do I create the thermal reliefs? When you place a polygon, select "pour over same net". This does it.
