Use unique rule hierarchy to tailor an analysis to bare-board construction, board density, or component technology. PCB Fabrication Analysis Fabrication analysis will detect specific design content that may have an adverse effect on PCB fabrication. Features such as less-than-minimal spacing, acid traps, minimal annular rings, minimum features sizes, and copper and mask slivers are just a few examples of the fabrication analysis available. Drill- related analysis includes minimal distances between drills, pads without drills, mill path errors, coincident or overlapping drills, and others. PCB Assembly Analysis Assembly analysis will detect specific PCB content that may have an adverse effect on PCB assembly. Solder and paste mask features—such as less-than-minimal mask spacing, missing masks, extra mask, and minimal mask annular rings— are examples of mask analysis available. Silkscreen-related analysis includes ink over pads, ink over mask exposures, and other checks. Error Charting Large-scale analysis can often result in a large number of reported failures. Viewing the results of large-scale analysis in chart form allows you to get to the root of the failure and quickly ascertain a remedy. Charting allows you to review specifics of the failures to identify trends or unexpected results. OrCAD DFM Checker's charting feature (Figure 1) reports the exact nature of the error and the PCB features related to that error. The charting function groups common errors so they can be quickly identified and resolved. Cross-Probing with OrCAD PCB Editor OrCAD DFM Checker is tightly integrated with OrCAD PCB Editor, allowing designers to walk through errors. Selecting errors within OrCAD DFM Checker and zooming into the error location within OrCAD PCB Editor expedites the process of finding and correcting errors in the source PCB design.
