Innovation is the key: how can we create value for our customers by saving space or energy, or creating a more reliable component?

Since every component we design is custom, we create the exact part needed for each application. This process begins with a conversation between your product design team and our expert design engineers. Heatron looks at the whole device application before making recommendations as to technology, form, controls or finishing. In some cases, multiple technologies or design approaches may be appropriate, resulting in a parallel prototyping situation.

The result is products that are optimized for performance, cost and safety. Heatron models, simulates, designs, integrates and validates your component before production to identify optimal design while driving out waste.

Heatron grows with you, pacing production to your regulatory and product launch needs.

Heatron’s ISO 9001 and FDA registered manufacturing facilities produce millions of heating elements, thick film circuits and LED assemblies per year. Using our design or yours, entrusting manufacturing and assembly to Heatron simplifies your supply chain.

Regulatory Compliance

Heatron can design to meet certification requirements for FDA, RoHS, RU, CSA, CE, TÜV, UL/IEC 60601 and other regulatory requirements. We are an ISO 9001 registered facility, and FDA registered establishment, and ITAR registered.

  • Etched Mica Heaters
    Etched Mica Heaters

    Heatron’s etched mica heaters are designed with tight traces and high watt density for greater control in applications with larger dimensions in an operating temperature range of -150°C to 500°C. Additional features include high rigidity, minimal out-gassing after first power up, and mounting holes for even application of heat.

  • Polyester Etch Foil Heaters
    Polyester Etch Foil Heaters

    The new HEATFLEX polyester etch foil heaters from HEATRON are designed to utilize advanced circuit imaging combined with chemical etching in order to allow designers to distribute wattage while creating multiple heat patterns in a single heater. These heaters are constructed using an etched foil heating element, and are available with custom watt density and multi-zone controls for added efficiency.

  • Flexible Heaters for Medical Devices
    Flexible Heaters for Medical Devices

    Heatron designs, and manufactures highly engineered flexible heaters and heating solutions for the medical device industry. These flexible heaters and heating elements are found in some of the world's most innovative and award-winning medical devices.  Heatron offers a range of flexible heaters designed to meet any challenge your engineering team is facing with product design.  If there is not a flexible heater solution, Heatron’s engineering team will work directly with you to develop a customized solution that fits your need.  The lines of flexible heaters for medical devices are:

  • Heatflex Kapton® and Polyimide Etch Foil Heaters
    Heatflex Kapton® and Polyimide Etch Foil Heaters

    Heatron’s Heatflex Kapton® and polyimide etch foil heaters are very thin and feature a flexible circuit design, high dielectric strength, precise heat distribution, low outgassing, and superior tensile strength for medical devices.

  • Ceramic Core Aluminum Nitride (ALN)
    Ceramic Core Aluminum Nitride (ALN)

    Aluminum nitride (ALN) is a hard, dense, non-porous, high purity substrate. It offers excellent thermal conductivity and uniformity, superior moisture and chemical resistance, excellent size and shape capability, a precise and repeatable pattern, and distributed wattage.
