The SimmScope is a first article inspection system that uses an overhead digital microsope on a motorized gantry to inspect the board - much like an AOI - except that it does not automatically make the pass/fail decisions. It is up to the operator to make the decision based on a visual comparison of the live image to the stored golden board image. The advantage over the scanning type systems is the higher resolution of the microscope for viewing small parts.
The system imports both the Gerber data and the XY list. It uses them to display a graphical "roadmap" of the board that can be used for point to point navigation. It can also be used to detect and correct errors in the pick and place program, as bad rotations will show up on the graphics. The corrected XY list can be exported back out to the Pick and place machine
A post inspection report is generated for traceabililty, as well as a color coded graphical printout. The report can also be loaded back into the machine to re-inspect areas of the PCB.
