Sergio,

Some are the silkscreen (the letters and symbols you see on one or both
sides of the pcb), the solder paste (used when you use surface mounting
devices), 8 phisical cooper layers and the nets, look for a general
tutorial on pcb fabrication or
http://web.wt.net/~billw/gsch2pcb/tutorial.html which is not intended to
be a PCB tutorial but is a very good resource.
