Communicating is hard. It took thousands of years just for man to develop a common language. Even in our current "enlightened" state, we should not expect it to be easy to develop a common, complete method for describing all the myriad features of a printed circuit board. And it’s not. Some 50 years after Gerber was invented, we continue to rely on it as the main format for expressing design intent to downstream production. But the Gerber format was never intended to include the increasingly complex data we ask it to, and its limits are showing. But while other, more “intelligent” formats have been proposed, none has taken hold. A new consortium, backed by a Who’s Who of OEMs and EDA vendors, including Harris, Ericsson, Fujitsu, nVidia, Sanmina-SCI, Cadence,Zuken, Adiva and Downstream Technologies, has emerged and, under the auspices of the trade association IPC, seeks to develop and accelerate adoption of an open, neutrally maintained global standard to encourage innovation, improveefficiency and reduce costs. This presentation is a trip through the decades of data transfer formats, from IPC-D-350 to ODB++, looking at why those formats have failed to become true industry standards, and provides a look forward at what could, at long last, be the panacea designers have been asking for since the 1970s. |
