That's all automated these days. And we resequence the boards before we Gerber. The PCB software generates the BOM. So it's always right. Occasionally an ECO will say to change a resistor to a capacitor, so R99 is actually a capacitor. Still no problem. -- John Larkin Highland Technology, Inc picosecond timing precision measurement jlarkin att highlandtechnology dott com http://www.highlandtechnology.com

OTOH, misspelled reference designators are a PITA. ;-)

That's bullshit. Your statistical inanity is showing.

We've had a lot of applications through Craigslist. Craigslist tends to generate a lot of activity with a small fraction appropriate to the job, but that's fine... just weed out the bad ones (graphics artsy types, unemployed MSEEs, foreigners looking for work visas). I probably have 8 good ones so far and they keep coming in. The spelling on the resumes tends to be bad, but then good PCB layout people often can't spell. -- John Larkin Highland Technology, Inc picosecond timing laser drivers and controllers jlarkin att highlandtechnology dott com http://www.highlandtechnology.com

A lot depends on the complexity of the PCBs, Are they dense multi-layer designs(6, 8, 10 etc.,) metal layer ones. Then you would need a professional who has clear understanding of vias (blind, through etc.,), ground planes on two sides of a signal plane(like in RF boards) and related but crucial details. It is doubtful if these pros will go through craigslist.

Actually, no, but it is stilted and funny. Cool, ballpark 10K zooming with high final resolution. Hilarious, all those gibberish voice commands.

The famous scene you are thinking of was "enhance" in Bladerunner. http://www.youtube.com/watch?v=qHepKd38pr0

About 3:1 superresolution is possible iff you have a very good understanding of the imaging optics psf and extremely good signal to noise. You can do slightly better for the position of very bright spikes on a dark background at infinity due to astronomical research. The general case with coloured objects not at infinity and finite depth of field is always more difficult in practice. Car numberplates can sometimes be done a bit better than the general rule of thumb.
> Refer to what was done with the MARS pictures.
Which Mars pictures do you have in mind? State of the Art before and after images for the defective Hubble telescope original optics are still about as good as it gets. You can't avoid the problem that high frequency noise is ultimately a killer. There are just too many noisy images that will blur to give exactly the same image that you recorded. You just have to pick the right one! -- Regards, Martin Brown
