Hi Michelle,
If you are looking for inner layer shorts, there
is no need to de populate, Polar produces a low
cost instrument called toneohm 950 which ise designed
to locate inner layer shorts using non destructive techniques..

Apologies for a commercial post, but its the right tool for the job...
Kind regards
