60 mil microcircuit device silicon die and applicable for devices with die sizes up to 14,400 square mils. For device die sizes greater than
14,400 square mils use the following values, dual-in-line, 11 C/W; flat pack and pin grid array, 10 C/W.are at the end of each trace.
resitance range is given, lower values are for five square inch aluminum PC board. Test PWB is 0.062 inches thick and typically uses
0,635 mm trace widths for power packages and 1,3 mm trace widths for non-power packages with a 100
