>For the art of PCB my professor always says that the diffrent layers must be rotate of 90°.

This is good practice, but is mainly done to make routing tracks efficient.

Default Orthogonality

tracks that are at right angle to one another have minimal magnetic interference. High frequency circuits are usually set up this way.

Hi Andy,

'D. Self' makes the suggestion that if you are going to do use this kind of grounding scheme that it is best to make the star ground connection on a stub off to one side of the heavy trace between the supply caps not to the heavy trace itself. His point is that there can be extremely large currents flowing in the trace between the two caps and by moving the star ground off to one side you eliminate the possibility that one ground trace feeding into the star ground might see a different ground reference than another.
