ABSTRACT:
A vaporizing device including a heating unit having a pair of electrical connector terminals staked to a substantially rigid substrate having a serpentine resistance type heating element printed thereon and electrically connected to the terminals. An insulating conformal layer coats the heating element, and wicks into the interstices of the region between said electrical terminals and the openings in the substrate receiving the terminals to significantly enhance the structural strength of the device. This provides an inexpensive and yet sturdy and rugged vaporizing device which may be discarded after each use.
