Ralph, In the IPC-6012 subcommittee meeting we addressed some of this. We asked the IPC to provide a paper trail from IPC-RB276 to IPC-6012. Something along the lines of running a revision on IPC-RB-276 which says that the spec has been superceded by IPC-6012. Therefore, we didn't have to change a bunch of drawings to IPC-6012 at once. We just change them as needed. I believe that IPC did do this for us. NOW, when IPC-RB-276 is ordered the one sheet IPC-RB-276 with the supercede note on it is sent and a copy of IPC-6012 is sent. I think this adequately addresses our drawing issues and, hopefully, yours. Regards, Dave Sullivan Rockwell Collins, Inc.

Not too long ago, after much spec comparison and analysis, we convinced our government customers that it would be prudent to move from Mil-P-55110 to the IPC-RB-276. In the time it took to get the new drawing callout approved, re-train the pwb designers and revise their guidelines, and bring our stellar board suppliers up to speed (no small task), RB-276 had been superceded by the 6012 document. Now I just learn today that IPC-D-275 is superceded by another document. This kills efforts to streamline and standardize documentation systems. Also, when these continuous changes take place, it would be convenient to have a detailed side paper published explaining all the changes (and maybe why the changes were made). May be a lot to ask, but it would keep every user from doing it individually. Anyone else see this as a problem? That's all the whining for now.
