Hi
The copper thickness requirement is the same but there is a minimum fill
requirement for blind and buried vias. The plating requirements is listed
in 6012B table 3-2, the fill requirement is stated in 3.6.2.16, beware
that for space and military avionics the requirements are tighter.

[TN] Via hole fill
Can someone be so kind as to direct me to the IPC specification that
covers filled via's. I am looking for the min average copper plating
thickness required. These are non-conductive filled via's.
Thanks in advance.Scott B. Westheimer5709 Clarks Fork DriveRaleigh, NC
