OrCAD ® DFM Checker identifies manufacturing issues often discovered by manufacturers prior to production that can result in costly time-to-market delays as designs need to be updated and reprocessed to address the issues. While manufacturers are fully capable of addressing minor issues, their resolutions are rarely fed back into the source CAD data, resulting in the same set of iterations of modifications on future design revisions. In worst-case scenarios, critical design intent may unknowingly be compromised when the manufacturer alters the source design files prior to fabrication. Overview OrCAD DFM Checker is a powerful, yet easy to use, manufac- turing analysis product. It is designed for engineers and designers who appreciate the benefits of manufacturing analysis and want to conduct it in a robust environment with ease and sensibility at all phases of the PCB design process. OrCAD DFM Checker offers comprehensive analysis to ensure the content supplied to the manufacturer will minimize costly delays. PCB designs that pass standard design rule verification within the PCB CAD system can unknowingly contain critical issues that derail an expedient transition to manufacturing and assembly. OrCAD DFM Checker identifies these design issues with the potential to result in low manufacturing and assembly yields or costly scrap, including insufficient spacing between design objects (pads, tracks, copper, drills, and vias), insufficient annular rings, acid traps, solder bridge potentials, isolated or starved thermal reliefs, and trace antennas, insufficient mask spacing, missing paste, missing solder mask, extra mask areas, and overlapping, coincidental, or redundant drills, mill path errors. Key Design Features Hierarchical Rule-Set-Driven Analysis The myriad of DFM checks and the overall analysis process can be easily managed by creating rules sets. Checks are organized into layer types and sub-categories to simplify the selection of checks to perform and the setting of corresponding parameters. Define the type and order of a group of checks (rule set) to be performed. Analysis can include netlist or layer comparison, design rule verification, fabrication, and assembly checks on the entire design, a specific layer. Analysis rule sets dramatically reduce set up and execution of the analysis and can be saved and recalled for use on any design. Rule sets can be defined for a specific PCB technology, vendor capability, or unique design requirement. Highlights • Comprehensive DFM analysis helps identify design issues with the potential to result in low manufac- turing/assembly yields or costly scrap • Checks are organized into layer types and sub-categories to simplify the selection of analysis to be performed • Checking routines can be created and stored for re-use on other designs, saving duplication effort • Addressing DFF/DFM issues helps reduce the amount of modification a fabricator makes to your design OrCAD DFM Checker Comprehensive and powerful DFM verification
