Hi Donovan, I guess it really depends on the product, how it's built and how you'd stress test it. Many arguments can be made about how far to test, then when one fails in the field was it due to manufacturing or test? But the bottom line is most

Yes, pre-loaded feeders is the best way. If you do not have that option as you are high mix or do work for different companies that have many different part numbers, I would guess that your printer will take about 15 minutes to get ready, each HSP f

For a microscope, you want one with the greatest working distance and depth of field you can get. You don't want a lot of magnification, so something like 0.7 - 20 X is good. If you are buying new, have salesmen bring them by and actually try them
