Ryan, not sure how much the capped vias increase cost. As far as
reliability, though, we've been using this design for many years in a
military avionics environment with good results.

Jim,
How has the cap plate filled via been working out on the production
line,
in terms or cost and reliability. We have had some customers
inquire about
the technology, but I don't have first hand knowledge.
Kind Regards
