Hello again. Question on IPC-610 (class 3) criteria. For SMT solder joints, there appear to be criteria set for TOE overhang, but not HEEL overhang. Is this an oversite or a purposeful omission? Is there a limit on how much the heel of an "L" shaped SMT lead can be off the pad lengthwise? The obvious and defined limit is "does not violate minimum electrical clearance", but does anyone else have info on this criteria?
