Very interesting. One of the things that held me back from picking up =20 one of these machines a couple years ago, was the ordeal of being able =20 to add plated-through holes. Back then, there were manually-inserted =20 "eyelets", which were also relatively large. Need to re-investigate =20 if this is viable for me nowadays. I have a couple fairly-accurate =20 machines now which I could probably use to mill the PCB's, and just =20 use their through-hole plating kit. In the meanwhile, that through-hole process looks like squeegeeing =20 solder paste in the holes and reflowing them. Watched the video, but =20 I'm still unsure how it plates non-vias (holes that would have =20 component leads) and what the tolerance is on these holes. Cheers, -Neil.
