    I am sanding a CPU die, trying to take a die shot of it.
    Many people suggest that I should keep sanding until I can only see the bottom copper layer of the die, and it is very reflective.
    The thing is, how do I know if it is the last layer? And what will happen if I continue to sand after the last copper layer is exposed?
