Ceramic Core Aluminum Nitride (AlN)

High thermal conductivity makes AlN an excellent choice where fast response or high levels of uniform temperatures are required. A clean, non-contaminating heat source, AlN’s high thermal conductivity prevents cracking.

  • High-temperature heater up to 1000°C
  • Excellent thermal conductivity and uniformity.
  • Hard, dense, non-porous, high purity substrate.
  • Superior moisture and chemical resistance.
  • Excellent size and shape capability.
  • Precise, repeatable pattern and distributed wattage.

Overview

Precision engineered to fit tight spaces and tolerances, Thick Film AlN heaters are found in the most critical  medical, aerospace and commercial applications. Fast ramp-up time, low leakage and excellent dielectric properties make this our highest-performing thick film alternative.

  • For high temperature applications up to 1000 °C
  • Power densities to 155 W/cm2 (1000 W/in2)
  • Superior thermal conductivity (220 W/mK)
  • Excellent dielectric properties
  • Low coefficient of thermal expansion
  • Low mass: fast temperature ramp up and cool down
  • Low leakage current
  • No out gassing with inorganic systems

Configuration Options

  • High temperature glass and conventional UV-cure resin-based solder masks or encapsulants.
  • Design single- or double-sided circuits, with one or two layers per side.
  • Larger, uneven shapes and three-dimensional configurations are possible with customization.

Wattage

  • Custom watt density designs available for added efficiency and control.
  • Multiple zone heating for greater control in target areas.
  • Distributed Wattage can be used to compensate for heat loss and create uniform temperature in application.

Voltage

  • Custom designed to operate from 2 to 480 volts; including dual voltage.
  • Functions with AC and DC voltage sources.

Surface Mount Sensors and Thermostats

  • Printed RTDs or surface-mount thermistors for direct, on-board temperature feedback and control, as well as more complex heater system assembly.
  • Large selection of thermostats and thermal fuses designed to provide maximum efficiency for your application.

Connecting Leads

  • Broad range of connection schemes available, including wire harness.
  • Custom connection solutions can be co-engineered with customer's design.
  • Power leads soldered directly to board or mechanically secured.
