If the unit is metric then the screws are 2.5 mm, 3.5 mm, and 4.0 mm

Re: microscope / high magnification camera options for soldering, faults, and other examinations/inspections
It's interesting to read the various posts.
I possess both video microscopes and binocular styles as well depending upon the work being done. Out of all I usually grab a video unit first off.

Re: microscope / high magnification camera options for soldering, faults, and other examinations/inspections
I do not recommend the digital microscopes, because they don't provide
stereo vision, which is really important when working on SMT components.
I've been using stereo microscopes for at least 20

Re: microscope / high magnification camera options for soldering, faults, and other examinations/inspections
Thank you all, great input.
From these choices, it sounds like a stereo microscope on a boom would be
ideal. I do tend to work on all sorts of positions and oftentimes spill
outside of the desk/bench.
