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."
Dieter Bergman, a champion of technical standards passed away on July 23rd. He was 82 and is survived by his wife, two sons and a daughter.
Consortium members have expressed great sadness over the loss. "A true pioneer in the industry" and "one of the great ones" members have described him. As "the heart and soul of the IPC Designers Council, "Dieter Bergman contributed greatly to the birth and development of IPC-2581 with his passion for the standards. He really knew PCB design inside and out, and the information could be instantly retrieved right from his memory. When a question was asked, you did not receive only the response from Dieter, but also how and why the answer came about. "A ten second question would receive a 10 minute response, "members have said this to be one of many "Dieterisms." The answer usually included the what, why, and who asked for a particular item in the specification being discussed. His memory was remarkable, his mind sharp till the very end.
At IPC Apex Expo 2014, IPC awarded 11 consortium members for their exceptional contributions towards the IPC-2581 standard. These awards recognize their efforts to get the standard updated in a record time - IPC-2581 RevB was proposed, updated and approved in 12 months!
I-Connect007 hosted a round table panel discussion recently about merits of various PCB design file transfer formats, Hemant Shah from Cadence Design Systems (representin IPC-2581 Consortium), Karel Taveriner from Ucamco (talking about Gerber) and David Wiens from Mentor Graphics (talking about ODB++) joined the discussion. Panel discussion was moderated by Ben Jordan from Altium. Gerber, ODB++ and IPC-2581, they all have their strengths, so which one should you choose?
