A method for producing electrical membrane panels including spaced conductive circuits on separate plastic film layers in which the membrane panels are formed on webs of the plastic films laminated together, and individual membrane panels are severed from the combined webs after being formed thereon.

Method for the manufacture of electrical membrane panels having circuits

Flexible heater panels comprising a light transmitting film substrate and a transparent conductive layer vacuum deposited on the substrate formed of (1) a light transmitting flexible plastic film substrate and (2) a vacuum deposited transparent conductive layer on a surface of the substrate selected from the group consisting of (i) a single lamina of tin oxide or indium tin oxide, (ii) a first lamina of indium oxide on the surface of the substrate and a second lamina of indium tin oxide over the first lamina, or (iii) a first lamina of tin oxide, indium oxide or indium tin oxide on the surface of the substrate, a second lamina of silver, platinum or palladium or alloys thereof over the first lamina, and a third lamina of tin oxide, indium oxide or indium tin oxide over the second lamina.
