I have looked profusely at IPC-6012 for a specification I could not find. I need to know if there is a specification for PTH drill accuracy and repeatability. We have a press-fit connector we are having problems with. The component manufacturer tested one of our boards and said the alignment is off 2 mils or more in some locations. I could not find what is the spec in IPC to reference to, could someone please point me to the correct document I should look at.
Sincerely,
SCOTT L
