Can a vacuum deposition work? Would the vapor get into small vias, say
0.008"? Maybe a fan inside would help?

stuff.

And how to pass component into that hole? Solid wire can be used only
for "vias".
Plating is to leave hole opened but to have electric contact with both
layers.
So if the hole is plated and you put resistor lead to the hole and
solder in one side, the capilar "wick" efect will pull solder into the
hole thru to other side. If hole is not plated then you must solder in
both sides. And there is the problem. Resistors can be soldered in both
sides but what for electrolytic capacitors?!?
