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,
