All Flex Heater Flex Design Considerations


All Flex engineering will work closely with you to ensure the proper
design and layout. We can also reverse engineer existing designs. The following are
typical characteristics and parameters of our heater circuit products. All Flex will review any application requirement and give you a sound design recommendation. For more information please contact our application specialists.

Applications Design Criteria Hybrid Circuits

Design parameters

Characteristics Typical Parameters
Size Range Less ½" square up to 10"X 22"
Temperature Range 80 deg – 250 deg f
Resistance Range 5 ohms – 250 ohms
Metal Thickness Range.0005-.002
Total Thickness Range .0045 - .015 w shielding
Dielectric Range /Insulation Resistance Same as flex circuits (FR)
Power 2.5 w/in2 –low end
5w/in2 – all purpose
10w/in2 -rapid warm up
Resistance Tolerance +/- 10%
Voltage 12 v up to 115 v
Coverlay thickness 1 or 2,3 and 5 mil
Other considerations:
  • Thermistor Assembly
  • Epoxy coated for environmental resistance
  • Heater can be built with multiple temperature zones
Critical Parameters to specify:
  • Temperature Range
  • Resistance (end to end)
  • Maximum Thickness
  • Power Requirements
  • Leads if required (length/ awg/ coating)
  • Length and width of heater

All Flex has the capability to quickly design, manufacture and deliver in volumes from prototype to medium production. All Flex has manufactured dozens of designs for the military, medical and industrial markets.
