What is PCB in NX?

Printed Circuit Board (PCB) Flexible Printed Circuits (FPC)

ECAD / MCAD Data exchange

NX PCB.xchange & PCB.modeler


What are NX PCB.modeler & NX PCB.xchange?

PCB.modelerEmbedded into NX Defines components, board assembly, restriction areas, drilled holes…Validates the Printed Circuit Assemblies (PCA) and generates HTML reportsEnables assembly clearance checks, and other packaging tasks to be performed within an integrated environment

PCB.xchangeEmbedded into NX Application dedicated to associative data exchange with all ECAD systemsReads/writes IDF files (v.2, v.3, and v.4)Data filtering while writing NX or ECAD modelsGenerates detailed HTML reportsAssociative bi-directional exchange of PCB data with ECAD systems (the NX part is validated and changes are tracked and controlled within the NX native or Teamcenter managed environments)

Working with existing ECAD Assemblies

IDF Standard support 3 LabelsTypically the primary identifier of a component part in EDA is its Part Number the MCAD user was to create a unique part for every electrical component number, versus a unique part for every component package (unique geometry) the MCAD component collection could be as much as 10 times larger

Package Name (also called Geometry or Footprint Name) Part Name

Part Number Stored as PCB assembly component attribute
