Hello,
It might be a basic question but....... Is it OK to place vias under a micro controller?
I am designing a PCB with an ATMEGA328P and I have already some vias under it. This is how it looks like:

hi,
I assume the PCB is only double sided and the via's are PTH.?
If so, I have used this method many times, under IC.s.
Be aware some components may have a cooling heat sink in contact with the PCB, so I would not use under via's in that case.
