| Dec 23, 2016 at 16:58 | comment | added | Sergei Gorbikov | Nick, 10x for an extensive and swift response. In your first comment, you meant copper area while used "copper pour" as i got: "If there are multiple traces covered by a copper pour, then the copper pour will short them." I got it, some people pour copper on the top layer this way hoping to reduce crosstalk or EMI. | |
| Dec 23, 2016 at 16:48 | comment | added | Nick Alexeev | @Sergei p.s. When I wrote this I didn't have OrCAD in front of me, so this is from memory. By the way, this nomenclature isn't universal across across various PCB design packages. For example, Altium has got Solid Region and Polygon Pour. | |
| Dec 23, 2016 at 16:48 | comment | added | Nick Alexeev | @Sergei Copper pour isolates tracks that cross it. Copper pour may also be attached to a net. In that case, it will isolate all nets, except the one that it's attached to. Copper pour has got a more complex behavior. In my experience, copper pour is used more often than copper area. Here's an example of a copper pour in one of my previous questions. Notice how the copper pour had created an isolation gap around the resistors and traces. | |
| Dec 23, 2016 at 16:47 | comment | added | Nick Alexeev | @Sergei Copper area is just a polygon filled with copper. If a copper area covers a trace, then it will paint over the trace. If there are multiple traces covered by a copper area, then the copper area will paint over all of them and short them. | |

| Apr 1, 2014 at 7:31 | comment | added | Andy aka | That's how I'd do it - overlap stuff with copper. | |
