What's even more interesting is that this is pretty accessible. Given fairly common equipment, at least in a hackerspace, you can make ~8 mil traces on plastic or FR4. Not only that, but you can make them in 3D and with plated vias.
This dude has some absolutely jaw dropping (sputtering, scanning electron microscope, waterjet etc) videos on his channel; it's definitely worth checking out the rest of his back catalogue.
- 6nf 8y agoGoogle tells me 'mil' is some kind of abbreviation for 'thou' or thousands of an inch which means 8 mil = 0.2mm
- gh02t 8y agoIt's an abbreviation for "mille", same root as the "milli" in millimeter. Common in electronics for describing trace widths and pitches, even outside of the US simply because there are lots of parts laid out in whole numbers of mils. 8 mil traces on a DIY circuit board is pretty good, it's good enough to be able to do some quite fine surface mount parts.
