Heatron|Alumina Thick Film Technology from Heatron

Heatron's alumina thick film heaters are custom designed and manufactured to meet a range of high-performance applications.  These heaters are ideal for applications requiring low profile packaging, uniform surface temperatures, high purity and chemical compatibility.  The alumina substrate can provide the highest insulation standoff per unit thickness of available heater material systems.

Alumina heaters provide ideal solutions for high-voltage AC or DC supply, small to mid-size heater, power resistor, and high-temperature circuit applications.

Operating temperatures can be up to 500 C (932°F).  The alumina dielectric can withstand greater than 5 KVAC depending on construction and design details.  Single or double sided circuits are offered.

Substrates can be produced in prototype through high-volume quantities via laser fabrication or tooled and pressed manufacturing.

Substrates for Heatron alumina heaters and circuits are typically laser-fabricated from standard sheet thicknesses of 0.010" to 0.050".   Stamped, green-scored and dry-pressed are also available for custom and high-volume applications.

Heatron alumina heaters are available on sheets substrates up to ~6" x 8" in size, which includes multiple part arrays.  For odd shape, 3D heater or larger size applications contact Heatron sales engineering.  Thick film heater circuits can be built on one or both sides.   High-temperature glass-ceramic and conventional UV-cure resin-based solder masks or encapsulants are available.  Value-added surface-mount circuit component assembly is provided in-house from Heatron, as well as more complex heater system assembly.

Voltage
Heatron alumina heaters can be custom designed to operate from 2 to 480 volts.  Series and parallel resistive heater circuits, including dual-voltage configurations are available.

Wattage
Custom watt density designs are available, providing added efficiency and control.  Our engineers can design different sections of the Heatron alumina heaters with different watt densities for surface temperature uniformity or to meet wattage targets in a given area of the heater.  Power densities greater than 20 W/in² for open air, 50 W/in² for clamp on are available.

Sensors
Heatron alumina heaters can be combined with surface-mount thermistors or RTD's for direct on-board feedback control. These SMT sensors on the heater can be provided with independent circuitry within the heater used to return the signal to the lead exit area, maintaining a desirable low profile.

Connecting Leads
Heatron alumina heater can be supplied with power leads soldered directly to the board and with a range of available SMT connectors.  Wire gages typically used are in the 18 to 26 AWG range, but a broad range of connection hardware schemes are available depending on basic heater size and design.  Custom connection solutions can be co-engineering with the customer's designers.

Agency Approvals
Heatron alumina heaters do not have specific agency approval, but have been built into many final assemblies and appliances that have US and international agency approvals.
