I couldn't resist the "can't see" part. I use a microscope in addition
to various other R/E stunts, and I can tell you that a multi-layer board
with the kind of circuits you have indicated, it it difficult enough to
see direct circuits, much less the backside of layer 4. They conceal the
circuit with "fake" traces. I have taken one down to the trace metal,
only to discover the + burn was not completed to the micro pin.
