Too many vias! Over 500 vias, plus the 30+ chips on a double sided board. Fortunately I have a machine to drill it in under 15 minutes very easily. Running wires through the vias is not fun. I am looking for ideas to "presensitize" the holes, then do some home brew bath for tin (copper, etc) plating. There will be a number of revisions, so board houses would take too long. One easy way out for the vias at least is silver epoxy which conducts very well, but not sure on its shelf life.
Anybody done this before for prototypes?
