Paragraph Number

84

In one embodiment, the graphite 810 is laid out on the substrate according to a predetermined pattern 814. Those of skill in the art will recognize that a variety of patterns 814 may be used. Preferably, the pattern 814 is a zigzag pattern that maintains an electrical path and separates lengths 816 of the graphite 810 by a predefined distance 818. Preferably, the distance 818 is selected such that a maximum amount of the resistance heat produced by a length 816 is conducted away from the length by the substrate, insulation layer 304 and the like. In addition, the distance 818 is selected such that heat conducted from one length does not impede conducting of heat from a parallel length. In addition, the distance 818 is not so large that cool or cold spots are created.
