I am in the process of making a requirements-document for manufacturing of a PCB. I would like to state some requirements for maximum allowable component shifting in the final PCB (both displacement and rotation). However, I can't find any (IPC) sta

Juan, I believe in term of height vs volume, volume is much better control. By the way we used Cyber Sentry 2000 which allows us to measure volume, height and area. My plant normal practice is measuring the height. Last time I did the control limit
