Hi Susan,

But aren't test coupons built on the edge of the panels made to be
sectioned? You can do both X and Y one thermally stressed, one not and see a
lot of potential problems. This causes absolutely no damage to the board
itself.

You don't need to do 100%, but occasional sampling may not be a bad idea.
You board vendor may even prepare them for you if you request it. (They may
be doing it as part of their own evaluation.)

Hi Rick and all
In my humble opinion - visual inspections are ones that can be done and
still
allow you to use the product, if found in conformance.  Microsection
inspections are destructive and the board can no longer be used.
