And again, not looking for a mechanical solution.? Already tried eyelets...they suck for so many reasons, the foremost being inconsistency of connection. Already tried soldered wires...this also sucks...mainly being a PITA to solder and they only address vias.? Any through hole connectors can't be done this way.
Also have tried conductive inks, paints, resins.? Never got more than about 75% of the holes being conductive.
