Our company has successfully fabricated bare boards using IPC-2581 with four fabricators including CC Electronics in Europe, Sierra Circuits and Sanmina in the U.S., and TTM-OPC in China. Our design flow includes Cadence SPB v16.6 for schematic capture/PCB layout and Wise VisualCAM for DFM/DFA checks, pallet design, and panelization of the single piece into the pallet.

Sierra Circuits, Sanmina, and TTM-OPC all used Genesis V10 to import the 2581 data and fabricate the bare boards. While working with Sierra Circuits and Sanmina we were performing a number of comparative checks between ODB++ and IPC-2581 in Genesis, this being the first opportunity we had to utilize Frontline Genesis V10. The results were very positive. When we engaged TTM-OPC we elected to only send the IPC-2581 data (No additional drawings, data, or external documentation). TTM-OPC were successful in building the bare boards using only an IPC-2581 dataset.

Leveraging the recent release of IPC-2581B we are now in the process of regressing PCB Assembly through our in-house Manufacturing (primarily Fuji SMT lines) using IPC-2581 data. We expect to have this fully operational by mid-year. We are also exploring the new capability introduced in Revision B that enables a collaborative exchange to enable PCB Stackup development between the OEM and Fabricator eliminating the use of spreadsheets, jpegs, and PDF files and instead using a subset of the IPC-2581B schema to exchange the BOM and parametric information of the materials selected to meet the design requirements.

IPC-2581B has come a long, long way....

Thousandsof PCB design layouts are done using Free CAD tools provided by PCB fabrication shopswhere there is no Gerber data or ODB++. Just send the entire PCB design file tothe manufacturer where you got the software. If you want to use a differentmanufacturer, they will provide you with Gerber data files for $150.

 

NowDownstream Technology has jumped into that business with the release of theirnew PCB design tool "SoloPCB" - www.fabstream.com<http://www.fabstream.com/

  

Press release –http://www.fabstream.com/news-detail.php?DownStream-Technologies-Launches-FabStream-2

 

Totally free CAD tool with integrated schematic. This PCBdesign solution is mostly used by EE engineers to get quick prototypes forcheap. But will this become popular with PCB designers? Regardless, PCB Libraries, Inc. fully supports SoloPCB in PCB Footprint Expert V2013 for PCB library automation.

Hi Matthew, More like dragging their feet, but 3 is sufficient for now, I have looked into this allot the last few months, most manufacturing and assembly suppliers will try to ignore "intelligent design intent" for as long as they can get away with it. however there are allot of DFM/DFA CAM tools out there which support it, Even the mighty Valor NPI, I have got word will be supporting this in their next release, and so is Oribitech.
 
So looking into my crystal ball I see a right royal rumble in the future between "intelligent design intent" ODB++ vs: IPC-2581, I am not sure what will become of Gerber, maybe it will always be around for the people who just want a cheap solution to their design without any verification.

Three.

So they are not hurrying to output it then Smile

Right now, Intercept's Pantheon, Cadence Allegro, Zuken CR-5000 can export IPC-2581 data but more will come soon.

CAM350 can import IPC-2581 format too.

What CAD packages can actually output it?

I love that phrase "Eliminates unexpected behavior in the Resize operation"!

Sounds like they're advertising the fact they've fixed a bug. LOL

Fantastic Tom, Thanks, I have also been told from Mentor's technical marketing, that in the next version of Valor NPI, IPC-2581 will be supported.

Frontline's Genesis CAM tool is the PCB fabrication shop's most popular front-end tool for DRC checking, panelization and setting up your designs for manufacturing. Mentor Graphics owns 50% of Frontline (Genesis).
 
They just announced in a flyer that they will be supporting IPC-2581 in Genesis V10.
 
Here's the new flyer - Genesis_v10.zip
