SOA introduces new microwave self heating sensor chips designed for thermal resistance measuring.

State College, PA March 2010 – State of the Art (SOTA) Inc., a leading manufacturer of military and high reliability chip resistors and electrically resistive products has introduced a new line of microwave heater sensor chips utilizing platinum on alumina and oxidized silicon.

These new heater/sensors can be utilized in 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 (mini-cell arrays).

Available with two design options, 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 designs with operating temperatures up to 250° C. 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.

Reliable operation is assured by SOTA’s considerable experience and rigid quality controls. Additional high reliability screening can be provided to further enhance reliability.
