Welcome to the real new millennium!

One of our board shops has suggested an alternative strategy to handle
through-hole vias for a PCB mounted on a flat metal plate.  They suggest that we
remove the bottom pads on all non-ground vias and then they will drill the
plated holes out to a depth of 0.010".  (The finished hole sizes for these vias
are 0.012" and 0.018".)  The previous strategy was to drill holes in the
mounting plate at the via locations.

Has anyone had any experience with this scenario?
Can you recommend any board shops that do this?
How reliable are the vias after this drilling?

Thanks for your feedback,
Roy
