The stereoscopic-zoom microscope provides a versatile optical viewing system. This viewing system
is used in the fault detection, fault isolation, and repair of complex microminiature circuit boards and
components. Figure 2-14 shows the microscope mounted on an adjustable stand. The microscope has a
minimum of 3.5X and a maximum of 30X magnification to detect hairline cracks in conductor runs and
stress cracks in solder joints.
