An electronic component having: a substrate, a lower conductor layer provided on the substrate; an inorganic dielectric film that covers the lower conductor layer; and an upper conductor layer having an upper electrode portion provided on the inorganic dielectric film. The PTA includes a communications path, a primary test controller, and a number of local test controllers. In certain embodiments, the volumetric construct can include a rolled remodelable material processed to form a substantially unitary body. The impeller is disposed outside the furnace in the vicinity of the opening of the housing.
