[SI-LIST] Re: Non-Functional Pads

Chris,

As a final step in our PCB design/layout process, we
standardly remove all unconnected pads unless the via
is for a press-fit/through-hole connection, where the pads
are needed for structural integrity.  This is done
prior to shipping the files to the PCB fab.
