Physical Size and Construction Limitations

Maximum Size: 10" × 22" (25.4 × 56.9 cm)

Dimensional Tolerance:

  • Less than 6":    ±0.030" (0.76 mm)
  • 6" to 12":    ±0.060" (1.52 mm)
  • over 12":    ±0.125" (3.17 mm)

Nominal Thickness: 0.008" (0.20 mm)

Weight: 1.5 oz./ft2 (0.05g/cm2)


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.
