It was announced at the IPC-2581 Consortium Technical Committee Meeting on June 29th, that the Ballot process for the approval of “IPC-2581B Amendment 1” had met the requirements for approval with a more the 90% participant vote, all of which were in the affirmative. The ballot officially closed on July 6 whereby IPC-2581B Amendment 1 was declared “Approved”. Again, the effort put forth by the IPC-2581 Consortium Technical Committee, in conjunction with the IPC 2-16 Laminate Sub-committee, and the IPC 2-40 Electronic Documentation Sub-committee has succeeded in improving and adapting the IPC-2581 format to support the growing technology and information requirements in the Design to Manufacturing process. The IPC-2581 specification document and schema are now in the process of preparation for publication.

IPC-2581 Consortium participated in PCB West 2015 on September 16th. PCB West this year, was an impressive conference that hosted many members of the PCB design and supply chain companies, including booths from the IPC-2581 Consortium and 13 of its members. In contrast to previous years, when the questions asked at the booth were “who are you” and “what do you do,” the questions this year revolved more around the tools that support IPC-2581 and the data that it contains. The knowledge that conference attendees had of IPC-2581 shows that the awareness of IPC-2581 has grown greatly in the PCB design environment.

The 2-16 Product Data Description (Laminar View) Subcommittee (IPC-2581) met in February during the IPC APEX Expo in San Diego CA. At this meeting final details for amendments and document updates as well as slight Schema modifications were addressed. The main focus of the meeting was to focus on an amendment of IPC-2581 Revision B to IPC-2581 Revision B1.
As part of the B1 modification, more descriptions, enumerated type and qualified string enhancements were made to enable adoption of 2581 Revision B without any structural changes to the schema. Examples for enhancements include, but are not limited to items such as more layer use type descriptions (flex type materials, masks, etc.), additional properties for parts and stack-up objects. The IPC-2581 Schema Document was also updated to record the new enhancements, correct spelling, and updated items overlooked between the schema and the document.

Enhancements to the stackup and assembly data have the supply chain signing on to the electronics data transfer format.
Eighteen months ago, Fujitsu Networks Communications CAD engineering manager Gary Carter shipped CAD files for a 12-layer PCB in the IPC-2581A format to a major board fabricator. The fabricator responded, asking for a drawing and profile information. It’s all there, Carter said, it just has to be derived from the CAD file.
The fabricator proceeded, and other than missing some data for machine routing for cutouts and V groove, Carter recalls, “They worked around what their CAM tool couldn’t handle, and they built it.”

The techniques used for moving printed board design data to manufacturing have many shortcomings, but the industry has never settled on a single approach for transferring data. Over the past couple of years, IPC and the IPC-2581 Consortium have teamed up in a concerted effort to change that.
With help from the consortium, IPC recently released IPC-2581B, Generic Requirements for Printed Board Assembly Products Manufacturing Description Data and Transfer Methodology. It was completed in a short 12-month timeframe. That quick cycle underscores the high level of interest that brought together companies from throughout the supply chain.

IPC 2581 Overview
PCBs have changed significantly over the past three decades, yet to the surprise of many, we still commonly use 30-year-old ways of communicating design intent to manufacturing. These decades old data-communication formats were originally conceived to drive the emerging numerically controlled machines. The Gerber format, properly implemented, is perfectly adequate to transfer image data, but it does not transfer stackup data, materials, design intent or netlist. IPC, the trade group, has been aware of the challenges and dynamics of the PCB design and manufacturing segment and has been an ardent advocate for the replacement of old data-communication formats.
In early 2001, iNEMI (the International National Electronics Manufacturing Initiative) stepped in to lead a broad, industry-wide project to define the definitive data exchange convergence specification. The goal was to enable accurate, efficient data exchange between designers and manufacturers of printed circuit boards (PCB) and assemblies using a single XLM-based data exchange format. From this effort, an IPC committee developed a new standard, IPC-2581, Generic Requirements for Printed Board Assembly Products Manufacturing Description Data and Transfer Methodology; it was released in March 2004.

Last year the PCB West conference held a lively panel discussion about data transfer formats for PCB design and manufacturing. Most panelists and many audience members were enthusiastic about IPC-2581, a vendor-neutral, "intelligent" format that can potentially replace many of the various formats in use today. At this year's PCB West September 26, 2012, two representatives of the IPC-2581 Consortium updated the progress that's been made towards this emerging standard.
Here's some quick background. The venerable Gerber format can transfer image data to manufacturing, but it can't transfer stackup data, materials information, design intent, or netlists. Therefore, PCB designers typically ship multiple files in multiple formats to fabrication and assembly houses. One attempt to create a more inclusive, intelligent format was ODB++, but since the 2010 acquisition of Valor Computerized Systems by Mentor Graphics, that format has been owned by Mentor. Thus, there's a renewed push behind IPC-2581, which was originally released in 2004, as a PCB CAD vendor-neutral format.

IPC-2581 consortium held a chat session yesterday on Printed Circuit University, which had been cordially supported and actively participated by professionals in the industry. So far, there were more than 1000 visitors to . The moderators, led by Gary Carter from Fujitsu, answered more than 20 questions during the one hour session. The most frequently asked questions were around why IPC-2581 and what could be improved by adopting IPC-2581. In answering these questions, Gary listed several benefits of adopting IPC-2581. First of all, IPC-2581 is truly an standard developed by an internationally recognized body IPC. Secondly, IPC-2581 could improve efficiency by eliminating data interpretation and documents to drive PCB fabrication, assembly and test operations. If you adopt IPC-2581, you will have improved support for drilled/routed content, improved embedded component support and improved support to net-list for manufacturing testability.
Although the moderators tried their best to answer all the questions submitted, the one hour time was still not long enough. It shows data transfer has been an area of high interest to the industry. In order to enable, facilitate and drive the use of IPC-2581 in the industry, all consortium members will be willing to respond to all concerns and questions that people might have with IPC-2581. So if you miss the IPC-2581 Chat session on Wednesday, don’t worry. You can contact us directly on our website IPC Apex Expo (San Diego, CA) and will have a booth there as well, where members can answer your questions about the new standard.. Also, the consortium will be presenting a poster next week (February 28 – March 1) at

2011 has been another eventful year in the PCB industry. As with all industries, we have seen our share of good news and bad news, mergers and acquisition, product announcements, plant expansions and company closings. But for me, there was one announcement that stood head and shoulders above the rest fro news worthiness: the formation of the IPC-2581 Consortium.
The IPC-2581 Consortium's charter is simple: To accerlerate the adoption of IPC-2581 as an open, neutrally maintained global standard to encourage innovation, improve efficiency and reduce costs. The members of the consortium will openly support and promote the adoption and usage of IPC-2581 by enabling their products, offerings and services to import/ export/ consume IPC-2581.
