J-STD-001C requires removal of gold from (through-hole) component leads when the thickness of the gold layer is above 2.5 microns to prevent problems with embrittlement. The thickness of gold on an ENIG board typically is around 0.05 micron, resultin

I just noticed that you mention 2-5mm off, that is huge! It would seem to me that there is an external force here to move a part that far. Things such as a heavy air stream that for some reason is really hitting this part, something on the PCB unde
