Technetters: Can someone tell me what the requirements are for PWB artwork stretch? I have a 12" long board where the artwork appears to be about .004" longer than the data from the gerber files. This is causing us much heartache during our screenprint process. As you would expect, it is also causing problems with 0402 tombstoning and fine pitch soldering as well. I could not find this in IPC-A-600. Thanks. Regards, Stephen M. Vargas Polaris Contract Mfg. Inc.
