Hi EveryBody!
Now you have to follow this carefully before answering.
Does anyone know, how can I make homemade PCBs with galvanized vias. I mean I do not want to solder a little wire, because it leaves bumps.
That is the question I asked and I got this answer.
Industry produced PCB have vacuum metallized vias. There no galvanic technology. However, you can try put your board to the surface of electrolyte, upper side of board must be dry, but holes for vias must be fully filled with electrolyte, to provide contact with the upper copper layer. That way you can fill vias with copper, but process is slow, and copper deposit will be loose.
Is this the right answer?
Thanks in advance!

Vacuum metallization - common name. This proccess called "Chemical vapour deposition". (in fact there no vacuum, but often its called so).
This document describe silicon coating, but its similar to via metallization, except process speed and gas composition.
