Anyone have a good way to do these? I have seen the micro rivets and solid wire methods, but none of them really seem to be worth a darn and not exactly easy to implement. Tried fooling around with some copper tape and rolling it into tubes, had a bit of luck but nothing spectacular. Tried the solid wire cylinder method, but that is a PITA if you don't have a drill the exact diameter of the wire, plus you need some sort of substrate that you can sand the ends of the wire flat. But yet PCB manufacturers are able to do them in all sizes effortlessly.
I mean just how the heck to they form the copper into such tiny tubes and cut them to length anyways? Closest thing I can imagine doing is taking some ultra-fine gauge copper wire, forming it into a coil around an inert hunk of plastic then electroplating the wires into solid tubing.
