I have heard this advice often.

I originally commented in my message at this point about how I found it
interesting to examine computer motherboards (but decided to delete it).
There is so much to those boards!  Some of the vias are nearly
microscopic (laser-drilled, I guess).  One thing I recently discovered
was the trace length matching in the SDRAM signals.  Some beautiful PCB
design.  I've practiced my hot air rework skills with some old
motherboards and studied their design while at the same time salvaging
some nice connectors, inductors, etc.

Colin
