Our ceramic heaters are among the highest performance heaters available in the market today.
Leveraging the powerful coupling of Aluminum Nitride (AlN) ceramic with internal Tungsten resistance heating traces, our multi-layer technology allows for complex tungsten circuitry and integrated temperature sensing. Fralock can produce a wide range of heater sizes and shapes to satisfy the demanding requirements of our customers.

We provide engineering support including full internal thermal modeling, CFD, and CAD design services for your thermal management requirements.

Heaters are available in multilayer ceramics or metal laminates of copper or stainless steel. We can thick or thin film metalize and plate to provide brazeable, solderable, or wire-bondable surfaces.

Internal and External Channels in Aluminum Nitride

The high thermal conductivity and low coefficient of expansion of AlN are employed to carry heat away from electronic devices through internal or external micro cooling channel layers added onto the multilayer circuitry. This can either be used for temperature transition applications or simply to remove heat from devices like laser Diodes, server processors, or power modules.

   Rapid cooling is achieved using micro cooling channels

Fralock can supply temperature control systems mated to our heaters to optimize the performance for your application. Due to the unique temperature coefficient of resistance (TCR) curves of internal tungsten sensor (RTD) traces, a specially calibrated control system is necessary to realize the full performance of our heaters. These control systems can be stand-alone or modules integrated into an existing control system. They can be configured to respond in milliseconds, virtually eliminating temperature overshoot.
Fralock can provide integrated cooling solutions for our heaters which provide extremely fast temperature transition on the cool-down side of the temperature cycle. Please contact us with your specific application.
