Rick,
I have seen designers use too small of a clearing on the inner plane layer
pass-throughs. I have also seen mechanical mounting holes that did not need to
be plated, get plated and cause a short. Newer DRC programs have helped reduce
such problems, but they somehow still crop up.
A good net list test, run from good net list data can also help preclude
defects. Whenever the layer count for .062" thick boards gets up to eight or
more layers, I like to have the board shop run High Pot testing on the boards.
