Hi,
I see a lot of BGA Rework stations that offer optical alignment and I'm curious about how it works.
I guess you need two right angle prisms placed in a cube with a mirror on one side like in the attached picture (sorry paint is all I had) but what determines the image size you can see and how does the camera that captures the image work?
I tried googling but can nowhere find a diagram, so if anyone could draw one in paint or whatever, or has some info I'd be thankful.
