About Power Planes Thickness

[MertkanTuna]

Hi all;

When i analyze open source projects like openrex, imx6 rex, all power planes thickness is 18μm. Is there any problem to change all power planes thickness 18μm to 35μm for increase current capacity?

Thank you a lot.

You can increase power plane thickness if you need.

PS: Normally I always ask for thicker power planes, some PCB manufacturers didn't want to increase it, so we left 18um
