I’m a big believer in standards but I’m not so sure why IPC is pushing a Gerber Coupon Generator when it has spent so many years developing IPC-2581, a much more comprehensive electronic data format.
Now in its B revision, IPC-2581 has been implemented in trial and production, and represents the most comprehensive set of industry requirements for printed circuit board fabrication, assembly, and test in a data-centric, open, license-free, industry driven standard format. Moreover, the consortium supporting its adoption boasts more than 90 members, including all the major PCB software vendors, plus a host of major OEMs, equipment suppliers, manufacturers, and service suppliers.
It’s time the emphasis be placed on moving the industry out of the buggy era. (Pun intended.)
Full disclosure: I’ve been a member of the IPC-2581 task group since its inception, and spent several years at IPC working on the predecessors to IPC-2581.
