Cooper Pour has holes

#1 Post by Roli » 15 Dec 2025, 22:26

In some cases I get small unfilled parts in the cooper pour. Usually this happens in the corner.
You see this holes also in the ODB++ productions files.

To fix the problem, try changing the “Line Width” value in the copper pour properties.

If I make it smaler, then I see it on an other cooper pour. I did not find a setting that works for all cooüer pours. In my opinion it is only a work around, but not practical for a long Time.

"Line Width" – size of the lines forming the copper pour. It is one of the basic copper pour parameters.
If you specify a different “Line Width” when creating a new copper pour, this value will then be applied when creating the next copper pour as well.

That the new cooper pour apply the changed line width does not really help, when on the same PCB a cooper pour has holes with 0.635mm line width and fill correctly with 0.1mm line width but an other cooper pour on the same PCB is fine with 0.635mm line width and shows holes with 0.1mm line width.
Do I really have to check every cooper pour that it has no holes in the cooper pour and adjust the line width till it's filled correctly?
or can you say my a line width that works for all cooper pours on the PCB correctly? I did not see this feature with the holes in Version 4.x.

In most cases, the copper pour area is filled without visible gaps. Only in rare cases, due to specific configuration and object placement, it may be necessary to adjust the Line Width value.
The developer periodically improves this algorithm. At the moment, in version 5.2.0.4, the pour result may differ slightly from the results in previous versions.
You can send your file to our technical support (support at diptrace.com), and we will check the pour behavior on your design in the latest version of the software.
