NEMI Productronica Demonstration
CAMX & PDX Standards

See press release

Presentation & Demonstration (November 7, 2001)

Purpose:

To demonstrate:

  • exchange of data among supply chain partners using Product Data eXchange (PDX) standards (IPC-2571, -2576, -2577 and -2578)
  • the ability to monitor production activity on a diverse set of manufacturing equipment, from different vendors and running different software, using the Computer Aided Manufacturing using XML (CAMX) standards (IPC-2501, -2541, -2546 and -2547).

The demonstration simulates production of printed wiring boards (PWBs).

Details:

  • Transfer CAD drawings · The OEMs’ engineering departments transfer CAD drawings of products to be built to the EMS providers, using GenCAM (IPC-2511). The GenCAM file provides details about all components used on the board, the dimensions and position of each, the reference designator (RefDes) for each part, etc. It presents a "picture" of the product, showing what components go where and how they are connected. The EMS providers display and translate the GenCAM file into information about set-ups and component loading for assembly.
  • Transfer product definition data · OEMs transfer BOMs and other production definition data from their respective product data management (PDM) systems to each EMS provider’s manufacturing execution system (MES) using PDX files (IPC-2571 and -2578). These files not only provide definitive information about the relationship between the circuit board and all parts used but also include such details as an approved vendor list (AVL), approved manufacturer list (AML), serial number ranges and change history.
  • Generate customer orders · OEMs generate customer orders from their respective enterprise requirements planning (ERP) systems, and transmit orders to EMS providers using RosettaNet Partner Interface Processes™ (PIPs®). The orders are loaded into each EMS provider’s MES, giving the EMS the go-ahead to build the boards as specified.
  • Product build · Each EMS provider sets up its shop floor production line according to the product build details. Component placement machines are loaded according to the automated build, and automated testers are loaded based on testing criteria and test scenarios. Boards are then run through the SMT line · built and tested according to the customer’s specifications. Using the CAMX standards (IPC-2501, -2541, -2546 and -2547), the EMS provider is able to monitor each machine on the line through its MES. At any given time, the EMS can determine where a particular board is in the process, what the state of each machine is, where there are test failures, etc.
  • Product genealogy · After the boards are built, PDX standard IPC-2576 allows the EMS and OEM to electronically capture (and transfer) the product genealogy (i.e., "build" information). The genealogy includes details about which components from which suppliers went into a particular board, and this information gives the manufacturer the ability to track and trace components in the event of a problem. For example, if the widgets from Company A are found to be defective and cause the board to explode, the OEM will be able to recall only those board that were built using Company A’s widgets, rather than recalling all boards produced in that particular batch.

The demonstation described above utilizes:

  • Teradyne’s GR Force/SCE, a supply chain execution system
  • Teradyne’s GR Force/D2B, a GenCAM viewer
  • Agile eXpress, an application that can be used to view and create PDX packages

Show Floor Demonstration

Purpose:

To demonstrate how the use of CAMX standards ensures communication across diverse equipment vendors and hardware and software platforms, connecting the many "islands of automation" on the shop floor.

Participants:

From the Productronica show floor:
Agilent Technologies
DEK Printing Machines Ltd
Teradyne Inc. (formerly GenRad)
Panasonic
Universal Instruments

From Georgia Institute of Technology:
Fuji America
Panasonic
Siemens
Universal Instruments
Georgia Tech Framework Portal Server

Details:

Throughout the Productronica show, the vendors participating in this demonstration are representing various pieces of equipment on an SMT line. In addition to the equipment on the show floor, machines located at Georgia Tech are part of the "production line," and simulators running at Georgia Tech are emulating additional manufacturing lines.

Each piece of equipment is generating CAMX-compliant messages (IPC-2541, -2546 and ·2547) to communicate information about its status and activities. These standards define the content and structure of the messages being sent and include, for example, details such as when an item enters a machine and when it exits; the state of each machine (on/off, idle, blocked, starved); results of tests; and warnings of any problems.

Messages are transferred using the proposed IPC-2501 standard. This standard, which is currently being developed by the Georgia Tech Framework Project, defines an industry-driven framework that will simplify communication among equipment and applications on the factory floor.

The framework features a message broker, which receives and distributes all messages coming from the equipment. There is also a framework portal, which aggregates messages from multiple sources and presents the information via a web-based graphical interface. It allows multiple users to monitor critical information such as cycle time, machine utilization and work-in-progress (WIP) so that rapid decision-making can be accomplished. During the show, users will · from a single interface · be able to monitor the equipment on the show floor, the equipment located at Georgia Tech and the simulated data. They will be able to know the status of a particular machine or where a product is in the process at any given time. Users simply specify which messages they want to see from which machines, and data will be presented · through their Web browser · in an easy-to-read graphical format. It is also possible to view raw message streams.

The CAMX standards will help manufacturers drastically reduce equipment and software integration costs, increase manufacturing flexibility and accelerate the introduction of new production capacity.

RosettaNet PIPs®

In developing the PDX standards, NEMI worked closely with, and coordinated efforts between, IPC and RosettaNet to leverage efforts toward a common goal and to ensure consistency between resulting standards. IPC created the 2570 series specifically for standards resulting from NEMI’s Virtual Factory Project. RosettaNet, an industry consortium focused on development of open e-business process interfaces, worked with NEMI and IPC to integrate the PDX standards into its own Cluster 2 and Cluster 7 Partner Interface Processes™ (PIPs®). These PIPs relate to distribution and update of production information and to the exchange of technical data for manufacturing.

Several Cluster 2 Product Information PIPs (2C1-2C6) have already been ratified. These interfaces enable distribution, and periodic update, of product and detailed design information, including product change notices and product technical specifications. Additional Cluster 2 PIPs have recently gone to RosettaNet members for vote (2C7-2C10). Cluster 7 Manufacturing PIPs, which will allow the exchange of "as-built" factory floor information, collaborative design and quality information reporting, are currently in development.

About the Georgia Tech Framework Project

The Framework Implemention Project, currently underway at Georgia Tech’s Manufacturing Research Center (MARC) is a spin-off of NEMI’s Plug & Play Factory Project. With initial sponsorship from several industry leaders, the project is developing factory information system products based on IPC’s XML-based standards for electronics manufacturing.

The project’s overall goal is to develop a framework that reduces costs and decreases cycle time throughout the industry by fostering interoperability among assembly equipment and software applications. The resulting specifications will be submitted for industry review as the IPC-2501 standard. Additional information about the Framework Implementation Project can be found at www.fis.marc.gatech.edu/framework.
