Choose via size for Via In Pad

noisepic , 01-23-2018, 08:08 AM
Is there technical requirement for size of via in case Via in Pad. I know some reason to decide the via size is: drill should > 1/10 pcb thickness; But the bigger drill can cause accurancy in manufacturing or less solder on BGA pin. Small size via high cost, What is the optium points?
