Needs to be steroscopic or else you'd be nailing bonds down in the wrong location. No substitute for a good stereo microscope for microelectronics work.
Maybe, but then you've got the lag and pixilation. Seems to be a solution in search of a problem. Still nothing nicer than human eyes looking through good glass of a stereo inspection microscope. Really not even the eyes, but the same posture for hours on end hurting the neck muscles. I suppose you can get used to it, but with a wire bonder there is not much leeway in adjusting the microscope position. Then again, for a guy manually wire bonding LEDs in China, it beats toiling in a rice patty.
Even the USB microscope cameras are garbage. Much better pictures just holding a digital pocket camera up to the eyepiece.
