Abstract:
A sensor assembly for being mounted on a circuit board (CB) comprises an interposer (I) with at least one opening (01, 02, 03, 04) extending between a first and a second main surface (MS1, MS2) of the interposer (I). The interposer (I) comprises at least two stress decoupling elements, each comprising a flexible structure (F1, F2, F3, F4) formed by a respective portion of the interposer (I) being partially enclosed by one of the at least one opening (01, 02, 03, 04). A sensor die (S) is connected to the flexible structures (F1, F2, F3, F4) on the first main surface (MS1). At least two board connection elements (SB) are arranged on the first main surface (MSI) and adapted for connecting the assembly to the circuit board (CB).
Abstract:
Es wird ein Membransensor mit einer Einfassung der Membran (2) in einer Halterung (1) am Sensorgehäuse vorgeschlagen, bei dem die Einfassung aus einer zusätzlichen Schicht (3;5;6;7) besteht, die auf der Seite der Membran (2), die dem zu sensierenden Medium ausgesetzt ist, entlang der Kante auf die Membran (2) heraufreicht und zumindest teilweise die feste Oberfläche der angrenzenden Halterung (1) bedeckt. Die Schicht (3;5;6;7) weist vorzugsweise eine Dicke auf, die nahezu keinen Einfluss auf die Strömung des mit einem Luftmassen- oder Luftgütesensor zu sensierenden Mediums hat. Die zusätzliche Schicht (3;5;6;7) kann aus einem in Dünnschicht- oder in Dickschichttechnik strukturierbarem Material gebildet sein.
