This is for a DC-DC converter.  5V @ 5A (max),
12V @ 1.2 A (max), and 3.3V @ 1.5A (max).  Assuming
1oz copper, I'm using 90 mil traces for Gnd and the
5V lines.  50 mils for the others.

At this point, I'm probably going to do this PCB
myself, since I don't want to wait past this wknd.
So it will be raw copper.

BTW, is there an (semi-)official chart of trace
width vs current capacity?  I've been using this
(also assumes solder-coated) as a basic guideline:
