On: PCB Design Tutorial for Startups

Stereo zoom microscope off of craigslist was the best purchase I ever made.

I got a Leica, but you can get really good Chinese ones for $400. If you do much PCB assembly, they're killer.

I wish I had a stereo inspection scope...

I've seen used boom-mounted dental microscopes on Craigslist or eBay periodically, and can't help but think they would be perfect for PCB assembly.

It's amazing how precise our hands can be when we have better magnification. Sub-mm accuracy of movement, which is a weird evolutionary trait if you think about it—more accurate than our unaided vision allows.

We access our sub-mm digital accuracy generally by touch feedback rather than by sight feedback.
