 Attributes of the Model Based Enterprise (MBE):  Tools and processes are integrated through the application of standard information  All data abstractions for functional needs are accessible through data management interfaces  Performance verified with science based simulation environments and augmented by required physical testing  Knowledge captured and fed back through every stage of the life cycle Integrated agile & flexible engineering, manufacturing, and operations characterized by modeling, simulation, and optimization, utilizing common processes and Integrated systems/tools/data standards across the extended enterprise. Model Based Enterprise Environment

Design for X (DFx) Vision: Design rules are implemented to allow early and consistent evaluations of new designs to identify and resolve issues prior to release for production Rockwell Collins first release of DFx has been Printed Circuit Assembly (PCA) Design For manufacturability (DFm): –Abstraction of standard information from CAD data –Manufacturing rules are run against design data –Visual representation communicates to the design team –Developed in a collaborative environment Second implementation of DFx is PCA Design For testability (DFt): –Same approach as DFm Third implementation of DFx is DFm at the Line Replaceable Unit (LRU) level: –In process

Design for Manufacturability Analysis of how Suited a PCA Design is for Manufacturing –Offline Process can be Run as Often as Needed During Design Process –Process Supports Balance Between Design and Manufacturing Needs Native CAD Data –Artwork –Component Terminal Locations –Drill Location, Size –PCA Bill Of Material –Milling Data Beyond Scope of Native CAD –Configuration Management (Product ID, Revision, Approvals, Date…) –Deleted/Replaced/Unpopulated Components in PCA –Fiducials –PCB Stackup –Assembly Panel (Tabs, Cutouts) –Standard Component Catalog Data –Component Manufacturing Properties –Component Manufacturing Classification –Textual Assembly Requirements

Design for Testability Analysis of how Suited a PCA Design is for Test –Extension of DFm Data Added to DFm Data –Native CAD Data: Component Reference Designations Realized in Printed Circuit Board (PCB) Netlist Component Placement in PCA Component Terminal Locations in PCA Land Locations in PCB Connector Signal-Pin Outs CAD-Defined Test Point Locations in PCB –Data Beyond Scope of Native CAD: Special Symbols Realized in PCB Tooling Hole Locations in PCB Special Lands for Terminals, Jumpers, etc… Special Test Point Locations in PCB

Departmental Specific Encoding of Domain Specific Features: Fiducial In the printed circuit card manufacturing domain, a Fiducial is a small mark included in a PCB used to align components Fiducials are required to be included in a PCB design and must be identified to facilitate design review and Computer Aided Manufacturing (CAM) tools. A Fiducial is represented in a Specific Design Department by a part with a name = “FIDUCIAL”. “FIDUCIAL” is not a material item so the originating Department filters any Bill Of Material (BOM) related data before publishing. Another Design Department may represent a Fiducial by assigning a name to some other CAD data type; the identification string varies. Fiducial is a predefined feature data type in the layout view in AP 210. If a Department published BOM-related data from an AP 210 database, no filtering would be needed, because features are not parts, thereby reducing maintenance costs.

Departmental Specific Encoding of Domain Specific Features: Filled Via In the PCB manufacturing domain, a filled via is a small plated hole that is filled after the lamination process. Filled vias may be included for various reasons. A Filled Via is represented in a Specific Design Department by a user defined classification defined in the released drawing. The identification of the fill material is included in a note. Filled_via is a predefined data type in AP 210. Material_identification is a predefined data type in STEP that is related to the fill material through a predefined relationship in AP 210.
