Roberto,
Two or more layers of plating (that are not separated) are the same as
one. Happy New Year!

Subject: [IPC-600-6012] double-layer copper wrap
Hello all!
The copper wrap requirement for filled holes asks for a continous copper
from
the hole to the pad. This wrap should be at least of a certain
thickness.
I would like to have your oppinions about the acceptability of this wrap
if it is
built of two layers.
For example if 12 microns thickness is required, we built two 6 micron
layers.
Happy New Year !
