Okay here's one for you, I can't find it in the standards, but I am sure that there is one. What is the specification for the temperature and humidity requirements when we are dimensionally inspecting circuit boards? What document is this located in and where in that document is it? I am looking for this information to add to our notes as we have a couple of holes on a circuit board that are +/- 0.001 (Don't shoot me! I didn't design it!) and with holes that tight I know I will probably need a note to cover this.
