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.
