Jim, Did you see the full screen photo of a quarter I posted when you asked about this before? I didn't even use a tripod for that, and the newer cheapie digital cameras with 5X Zoom and 12 Megapixels do better than my 3X 8 Megapixel GE. A cheapie GE 5X/12 camera would take ID photos of SMT chips.

The most important thing was to manually white balance the camera. Of low cost cameras CANON have by far the best optics and a "super" macro mode that focuses down to 1 cm (0.4 inch). A remote shutter release is a good idea but you can work without it.

This places the camera in a position that works great for shooting straight down at an object, like a copy stand, I've also found that, when shooting at extreme close-ups, pushing the trigger can vibrate the camera and blur the image. I use the timed trigger to eliminate that. Ken

They are made by Nikon, but cost a lot more. Leon

You can use a tripod if you're not doing this often, but harder to set up. Lighting is the biggest problem. A couple links to lighting suggestions below. I find the gallon plastic milk jug diffuser with two or three work lights with 100 watt equivalent fluorescent bulbs to be very handy. Another way of "photographing" chips is put them on a flat bed scanner. They have sufficient depth of field to scan PCBs with 0.2" tall parts.
