SOTA introduces new microwave self heating sensor chips for thermal resistance measuring

Posted by John McHale

STATE COLLEGE, Pa. 13 March 2010. State of the Art, (SOTA) Inc., introduced a new line of microwave heater sensor chips utilizing platinum on alumina and oxidized silicon.

These new heater/sensors can be used applications such as microelectronics and biomedical engineering. Potential applications include determination of thermal resistance of IC chips, variable optical attenuation of arrayed waveguide gratings, and thermal management in miniature chambers (mini-cell arrays).

Available with two design options, the TM365 with two thermal sensors in close proximity to the heater for stringent temperature control, and the TM364 single sensor design with moderate temperature control. Both designs have operating temperatures as high as 250 degrees Celsius. The self-heating of the sensors is below 4 mW/ C. Applications specific, custom designs can also be developed based on the customer's drawings.
