Those of you new to power design probably haven't learned yet how crucial PCB layout is in our field. The power stage gets laid out the old-fashioned way, manually, and the reasons are discussed in the articles below.

If the experienced engineers want to add some more rules, feel free to share them here.
Or, if you have some classic real world experiences to share, that would be good too.

I have 9 basic rules I use for layout, and you can find these in article [43] and [44] in our design center. http://www.ridleyengineering.com/design-center.html [43-44] Power Supply Development Diary Parts X and XI

If you have a layout engineer not familiar with power (or even if he is) these rules can be useful to share with them.
