Hi Technetters,

Does anyone know of any specifications that define the electrical testing
levels for an assembled backplane?
What I have always used as a definition is:
Level 1.  Top Side Pin to Bottom Side hole continuity is tested.
Level 2.  Level 1 plus Pin to Pin continuity is tested.
Level 3.  Level 2 plus all components are tested for correct values
Level 4.  Level 2 and 3 plus all active devices (IC's, etc.) are tested.
I have looked in the IPC bookstore and did not see anything (probably
looking in the wrong spot).
Would appreciate any and all comments.
Thanks,
Kerry
