Self-Heating Sensor Chips Help Measure Thermal Resistance

The company’s line of microwave heater sensor chips employ platinum on alumina and oxidized silicon and suit a host of applications in areas from microelectronics to 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. Two options are available: the TM365 with two thermal sensors in close proximity to the heater for extremely stringent temperature control and the TM364 single sensor design with moderate temperature control. Both specify operating temperatures up to 250°C. For more details, call Bernie Hoy at State of the Art Inc., State College, PA. (800) 458-3401.
