With ceramic instead of copper, should have less expansion etc. All
zero ohm resistors would make it no real component to see anyway, just a
nice little wire carrier that stays in the hole by itself before you
solder.. But in with the original though was also that you could hide
functional resistors this way, if you really worked at it you could make
a board tougher to figure out.. Still, anyone looking at it with a
meter should spot the non-zero trace resistances fast enough, even if it
takes them a little to work out where the resistors are.
Mainly mentioned it for the idea, I hardly ever use vias myself.
Rectangular strip metal with indentions to make it snappable, and a
press to press it and split the ends over to the sides, would be a dirt
cheap via maker. Wouldn't be circular like the other rivets so no
through hole, but find metal strips already made and just sell 2 tools,
one to perf the strip, and a press to cinch them in. Still hardly worth
doing, but 10 times less cost than the circular ones..
