Not recommended, because some solder will wick down to the other side and the component on top will not solder correctly.
Remedial measure:
Remark: Before designing via-in-pad, don’t forget to talk to your PCB fabricator to find out what their capabilities are, and how much extra this costs.

I designed a PCB with an imaging sensor that is mechanically coupled to a lens assembly using four 2-56 screws. I’m noticing that even though the screws are holding the board tightly against the mechanical structure if I flick or lightly knock the the assembly the image “moves”. I’m hoping to get a few suggestions for ways to fix the PCB to the mechanical structure. Any suggestions for adhesives or the like? Something else?
It is a nice looking breadboard, but the terminals are too loose to make a good connection on any components. so I couldn’t actually use them for anything.
My PCB antennas fail to achieve resonance, though I have changed their length. Our new product project is obstructed due to this problem now. Are there any good solution else?
