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 !
