    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: A photoacoustic gas sensor device is proposed for determining a value indicative of a presence or a concentration of a component in a gas. The photoacoustic gas sensor device comprises a substrate (1), and a measurement cell body (2) arranged on a first side (11) of the substrate (1). The substrate (1) and the measurement cell body (2) define a measurement cell enclosing a measurement volume (3). The measurement cell comprises an aperture (4) for a gas to enter the measurement volume (3). The device further comprises an electromagnetic radiation source (7) for emitting electromagnetic radiation (8), and a microphone (6) for measuring a sound wave (9) generated by the component in response to an absorption of electromagnetic radiation (8) by the component. The electromagnetic radiation source (7) and the microphone (6) are arranged on the first side (11) of the substrate (1) and in the measurement volume (3). The microphone (6) has a bottom port (61) facing the substrate (1), and the measurement volume (3) is communicatively coupled to the bottom port (61).
