We hope to make bigger volumes with IST AG
The perfect fit for any application
Micro heaters are used in devices requiring a small but accurate heat source with precise temperature control, such as optical interactive assistance systems. Allowing for targeted heating of tiny spaces, IST AG micro heaters are found across various industries, including automotive, laser manufacturing, humidification units, life-science, 3D printing and medical devices. They are a precision heat source for gas and humidity sensors, biopsy or tissue samples for medical analysis, or used in malignant tumor treatment. Each micro heater is individually customized and designed to fit your application’s requirements.
Benefits and Characteristics
IST AG micro heaters can be tailored to any application to enable an even heat distribution across a small surface. They allow for targeted heating of tiny spaces.
Special Form Factors
The possibilities for chip shapes as well as the geometry of heating patters are endless and can be designed to fit precisely into any application.
We design the micro heater to fit the application’s profile offering a wide selection of substrates, from alumina to zirconia.
Whether round, polygons, long and thin or square, the substrates can be cut with precision laser into any two-dimensional shape, providing the form factor needed to fit the application.
Various substrate materials can be utilized to be compatible with objects to be heated. Thermal conductivity, which influences the heat transfer from heater to object, varies for different substrates. Depending on the requirements the choice of will be made from the following selection: ceramic alumina, zirconia, sapphire, steel, copper, polyimide, aluminum nitride or silicon wafer. Ceramic substrates, for example, have excellent corrosion resistance and the highest operating temperature range.
The heat transfer from heater to object, varies for different substrates. Stainless steel has the lowest value of about 15 W/mK, aluminum nitride has the highest value up to 220 W/mK.
