I meant to include this in the original message. One, the solder balls are on the circuit side of PCB. Two, some of the vias on both top and bottom are closed and some are not. Is this a process problem with the board house(s)?

Hello All, I am having issued with insufficient solder due to via in pad. It is a 10 mils via and PCB is 70 mil thick. Six mils stencils was used since there are some 20 mils (No clean process). Any recommendation? Thank you.
