Fellow TechNetters: I will submit my initial inquiry once again. During my search of IPC Standards I ran across this reference. The above stated IPC DTD makes a reference to another doc, IPC-01-645. I was not able to find a link for it. Can anyone chime in with comments and/or suggestions on this task?
