For years one of the hangups for any data transfer format hoping to supplant Gerber has been the lack of independent validations that the output from a given CAD tool could be accurately read in CAM.

That’s why the IPC-2581 Consortium is right to herald today’s announcement of not one four independent validations as a “significant milestone.”

Today the Consortium published a validation matrix showing data output in Cadence Allegro and Zuken CR5000 has been correlated and validated against typical proprietary and multi-file manufacturing formats by Adiva, Wise, EasyLogix and DownStream. Those CAM vendors also are launching viewers — free, in most cases — to help users compare the data themselves.

The Consortium will take its show on the road next week, presenting a paper at Apex and also at the Cadence users group meeting in March. Both events represent an opportune time to question the members on their progress. If you can’t make the conferences, tune in to PCB Chat on Feb. 22, where the members will answer questions in our new online moderated chat forum.
