And one more thing I would like to add, if you are looking at hand-held camera-type inspection systems, stay far away from those that are made with a plastic housing. Most of these generate huge amounts of static and should not be used around electronics. In fact, there was even a GUIDEP alert for this. The manufacturers of these "inspection systems" have absolutely no knowledge or awareness of ESD with respect to using them as electronics inspection systems. When I inquired as to their suitability for use in our industry from an ESD standpoint, their response was "What is ESD?" They also said "Our product has been used by all of these different large companies with no indication of any ESD issues". Well, of course not. Who woulda thunk it?

We use standard Leica and Olympus microscopes. I have used Mantis systems at other clients but they were eventually phased out as the operators all preferred the standard scopes for clarity and the Mantis were just too large and in the way.
However, for visual inspection of heel fillets and for inspection of BGA solder balls and other tight spaces that have tall adjacent components that block direct viewing, all of the companies I work for utilize inspection prisms that work in conjunction with the standard scopes. They allow the inspectors to look in pretty much every direction, regardless of the position of the scope itself. The hand-held prisms can be purchased from a number of supply stores. 
Here is one: http://www.eis-inc.com/suppliers/productlist.asp?prod_area=270&showcase_no=200439UC2.
Please understand that some brands of these mirrors are more "robust" than others. Try some from different manufacturers and select those that your operators like best.

Subject: [TN] Fine Pitch Heel Fillets

Good Morning:

     We are looking for some enhanced tools / equipment for inspecting fine pitch leads for Class 3 compliant heel fillets. We currently use standard microscopes and Mantis systems. I'm sure there are a lot of equipment suppliers who advertise exactly what I am looking for, but I want input from actual users. Thanks.

Regards,
Steve Vargas
