The only viable solution involved re-routing. That's a significant modification under any circumstance. It would have been easier if the BGA pads that required re-routing were on the perimeter of the BGA layout, but such was not the case.

The newly routed pads had to extend from the center of the component to outside of the package footprint so that wires could be added to the newly placed pattern of surface mount pads ...

imageStereo Zoom Microscopes: Rework’s Essential Tool

Microscopes have become essential tools in the rework and repair department. While there have been (and still are) many applications for other types of manually-operated vision systems, such as illuminated magnifiers and CCTV based systems, the importance of microscopes has been driven by the ever-shrinking size of electronic components, connections, and assemblies, and the spaces between adjacent components.

Microscopes used in this scenario are almost exclusively stereo zoom microscopes, which offer depth perception for the operator (as opposed to monocular scopes), and the ability to ...
