Hi,
By filling them completely ICT vacuum fixtures work better. However that is
probably not done today?

Subject: [TN] Why do we fill vias, anyway?
Hello all,
I've recently had some PCBs rejected for incomplete via fill. This would be
in 8 mil vias, aspect ratios between 9.5 and 10.3, to be filled and plated
over.
I realized I have no idea why, or if, it is a good idea to fill vias.
Is anyone aware of PCB failures due to incomplete via fill?
And finally, is anyone else have trouble searching the Technet archives? I
used to get good information that way, but now all my searches return zero
results.
Best regards,
