Abstract:
The present sensing device comprises a sensor (1) for providing sensor data representative of a quantity to be measured. Together with the sensor (1) a radio frequency interface (2) for transmitting the sensor data is arranged in a casing (3). The casing (3) comprises an opening (33) for exposing a sensitive element (11) of the sensor (1) to an environment of the casing (3). A seal (4) is provided for sealing the opening (33) against an interior (3) of the casing (3). The sensing device can be used as autonomous humidity detector for detecting humidity e.g. in cars under test.
Abstract:
The sensor assembly comprises a substrate (1), such as a flexible printed circuit board, and a sensor chip (2) flip-chip mounted to the substrate (1), with a first side (3) of the sensor chip (2) facing the substrate (1). A sensing area (4) and contact pads (5) are integrated on the first side (3) of the sensor chip (2). Underfill (18) and/or solder flux is arranged between the sensor chip (2) and the substrate (1). The sensor chip (2) extends over an edge (12) of the substrate (1), with the edge (12) of the substrate (1) extending between the contact pads (5) and the sensing area (4) over the whole sensor chip (2). A dam (16) can be provided along the edge (12) of the substrate (1) for even better separation of the underfill (18) and the sensing area (4). This design allows for a simple alignment of the sensor chip on the substrate (1) and prevents underfill (18) from covering the sensing area (4).

Abstract:
In a method for manufacturing a sensor chip a spacer (3) is arranged at the front side (11) of a substrate (1) at which front side (11) a sensing element (2) is arranged, too. Holes (14) are etched for building vias (15) extending through the substrate (1) between the front side (11) of the substrate (1) and its back side (12). After etching, the holes (14) are filled with conductive material to complete the vias (15). The spacer (3) provides protection to the sensing element (2) and the sensing chip throughout the manufacturing process.

Abstract:
The sensor assembly comprises a substrate (1), such as a flexible printed circuit board, and a sensor chip (2) flip-chip mounted to the substrate (1), with a first side (3) of the sensor chip (2) facing the substrate (1). A sensing area (4) and contact pads (5) are integrated on the first side (3) of the sensor chip (2) and located in a chamber (17) between the substrate (1) and the sensor chip (2). Chamber (17) is bordered along at least two sides by a dam (16). Underfill (18) and/or solder flux is arranged between the sensor chip (2) and the substrate (1), and the dam (16) prevents the underfill from entering the chamber (17). An opening (19) extends from the chamber to the environment and is located between the substrate (1) and the sensor chip (2) or extends through the sensor chip (2).
Abstract:
In a portable electronic device components (2) consuming electrical power during operation may generate heat. A temperature sensor (1) for sensing an ambient temperature (T s ) of the portable electronic device may as a consequence not supply the correct temperature value. It is suggested to provide a compensator (4) for determining a compensated ambient temperature (T A ) dependent on at least the sensed ambient temperature (T s ) and information ( P i ) related to the electrical power consumed by at least one of the components (2). After a power down and a reactivation of the portable electronic device, actual internal states (x(b)) of the compensation model are estimated dependent on last internal states (x(a)) stored at the power down, dependent on an estimated course of the sensed temperature (T* s ) between the interruption and the reactivation, and dependent on an estimated course of the information ( P* i ) related to the electrical power consumed by the at least one heat source (2) between the interruption and the reactivation.
