There are 3 types of copper on a PCB:
- Plane Area: Closed polygon representing a single net like power and ground. Two or more partial planes can occupy one layer each with a different net. This is known as a split plane. Planes are generally located on internal layers. Planes are created on Split/Mix layers with a pre-selected netname. Planes be automatically generated using board outline. A mixed plane contains plane area(s) and traces.
- Copper: For use as heat sinks, shielding and net bridge. A net may be assigned to Copper. Can be created in Decal Editor as a decal/footprint.
Copper Pour: Typically used for power or ground plane with insulated traces and vias passing across the plane area as long as they do not divide the area and break connectivity. It can be solid (flood) or hatched pattern. It is not filled automatically and must be poured.
- Use the Setup/Layer Definition Dialog to define each layer in your design.
- Select the plane layer and check it is set to Split/Mixed.
- Select Assign Nets.
- See the video below for detailed instructions on creating a plane shape using polygons or the board outline.
- Use Tools/Pour Manager to setup details about plane or copper areas.
6. Select Setup to edit details for hatching and flood.
