Etched Foil Element:

Made with a thin metal foil (.001"), usually a nickel base alloy, as the resistance element
Resistance pattern to be etched is designed in CAD and transferred to the foil, which is laminated to the insulating substrate; the element/substrate is then processed through an acid spray to produce the desired resistance pattern; the top layer is then added and laminated
Lead wires are attached to the heater and insulated epoxy cement
Has exceptional heat transfer due to its large flat surface area.
Can deliver uniform heat profiles with higher watt densities, providing longer operating heater life
Can also be zoned with distributed wattage or separate heating circuits to compensate for load variations
Recommended for small size heaters in large quantities.
