IST RTD Platinum Sensors: FlipChip Series

Featured Product from Innovative Sensor Technology IST USA Division

Temperature measurement is one of the most important physical parameters when determining quality, accuracy and reliability of processes not only in industrial use, but also in almost all human activities. Temperature sensors are produced with different technologies to fit specific application requirements.

IST AG has concentrated one part of the development and manufacturing on high-end thin-film temperature sensors. This know-how is partially derived from the semiconductor industry and allows us to manufacture sensors with high accuracy, excellent long-term stability, high reliability and repeatability within a wide temperature range from -200 °C up to 1000 °C. Because of very small dimensions and low thermal mass, the thin-film temperature sensors exhibit a very short response time.

IST sensor products from the FlipChip Series are RTD Platinum sensors without leads suitable for automatic assembling on PCB by soldering and bonding.

Depending on the connection process and the required temperature range you could choose between the different types:

-          1 FC     tin-coated, LMP lead-free,   96.5Sn/3Ag/0.5Cu) ,reflow soldering (max +150oC)


-          2 FC     tin-coated, HMP soldering depot,5Sn/93.5Pb/1.5Ag , reflow soldering (max +250oC)


-          3 FC        Au-Pads (bonding pads), various types Available (max +250oC)


-          5 FC        reinforced thin film Pt-pads (solderable pads) (max +400oC)


-          6 FC        thick film Pt-pads (weldable) (max +600oC)


Benefits and Characteristics:

  •  Excellent long-term stability
