* The standoffs shall be so located as to give a lead clearance of 0.010" minimum between the resistor body and the printed circuit board  
when the standoffs are seated on the printed circuit board. This is to allow for proper cleaning of flux and other contaminants from the unit  
after all soldering processes.
