The pc532 only has 4 active layers (6 total), the 2 outer ones on each side.
Sandwiched in between these are the 2 power planes - one vcc the other gnd.
You can see all the active traces since there is nothing in-between the
power planes, the traces on the inner layers appear black.

PLEASE NOTE THAT WHEN YOU DRILL THROUGH YOU MUST BE CAREFUL NOT TWO SHORT THE
PLANES WITH BITS OF COPPER - ALSO, DO NOT USE CONDUCTIVE SCREWS FOR THE SAME
REASON. USE PLASTIC OR OTHER NON-CONDUCTIVE MEANS.

I personally would not want to drill through the board even being careful
to remove all pieces of copper from the drilling exercise - but good luck.

best regards,
