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.)

Microsection inspections are destructive and the board can no longer be used.
