Copper Balancing/ Copper Thieving creation
Max , 03-09-2021, 06:26 AM
Hello all,
Could you please share how you are designing copper balancing?
I am trying to follow the approach proposed here Via Stitching for advanced copper thieving venting patterns - YouTube, by using Via Stitching. For some reasons I cannot repour polygons out of the board outline, I am not sure if it is a setting I can play with or by default. I am using Altium 20.2.6 version.
Thanks in advance,
Max

I would be also interested to see some comments on this - I do not do that, so I am curious.

Before moving the polygons , go to "Polygon actions - explode selected polygons to free primitives"
everything else is pretty much the same

If it is balancing the copper between layers to prevent a bend board there are other options:
- place a polygon on the top too (all layers have polygons)
- Use the hatched option for the polygon
- Place polygon pour cutouts
Do remember to connect the copper as much as possible (no floating islands) as it will cause problems. https://www.youtube.com/watch?v=y4REmZlE7Jg or even better the discussion that followed (not recorded that I know of) where the floating part was discussed with Eric, Steve Sandler and Rick Hartley (if I remember correctly).
I always place polygon pours on all layers and stich them together (manually) as much as possible. Islands are removed and the net is Gnd.
