40 SMT007 MAGAZINE I MAY 2025 is granular logging of recipe tweaks pro- vides visibility into temporary, local adjust- ments that are not reflected in the main rec- ipe. e new LocalRecipeChanged message complements the existing RecipeActivated message (which still signals when a recipe is loaded or started on a machine) by captur- ing any subsequent deviations from the base- line recipe without altering the original rec- ipe definition. Standardized Unit Identification and Message Alignment CFX 2.0 also includes clarifications and minor structural updates to ensure consis- tency in data across different scenarios: • Production unit identification: e stan- dard now more clearly defines how to pop- ulate PCB PrimaryIdentifier vs. UnitIdenti- fier fields for various panel configurations. For example, if a panel has a single barcode for the entire board and contains multiple units, that one barcode should serve as the required PrimaryIdentifier while individual UnitIdentifiers may not be needed for each unit. Conversely, in a panel where each unit has its own barcode (and no overarch- ing panel code), the first unit's ID is used as the PrimaryIdentifier and each unit's barcode is reported as a UnitIdentifier. ese rules standardize how multi-up pan- els and single boards are identified in all CFX messages, ensuring traceability data is reported uniformly. • Other alignments: A number of smaller improvements were made for clar- ity and interoperability. CFX 2.0 intro- duced additional process interlocking message topics to allow for better con- trol of tools, materials, carriers, and pro- grams by a super visor y soware system such as a manufacturing execution sys- tem (MES). e data model for tray-type component feeders in SMT machines was also refined for more accurate reporting of feeder events. Various message defini- tions received minor clean-up for consis- tency (terminology alignment, etc.), all of which were included in the Version 2.0 documentation updates. ese tweaks, while not as high-profile as the new mes- sages, help to eliminate ambiguity and improve the "plug-and-play" interopera- bility that CFX ensures. Each of these enhancements in IPC-CFX 2.0 was driven by real-world manufactur- ing needs and vetted by the IPC task group to maintain compatibility with earlier ver- sions. e result is a more expansive and detailed standard, one that not only cov- ers a wider array of production processes (from automated vehicles to hand solder- ing) but also continues to deliver richer data from machines, enabling smarter analytics and more efficient operations across the con- nected factory. IPC-2591, Version 2.0 also includes updates to support usability and better visibility of equipment on the IPC-CFX-2591 Qualified Products List (QPL).
