A system comprises a chip (71) and a substrate (78). The chip (71) comprises a circuitry and a mounting surface (83) with first and second contacts (73, 74, 75, 76). The substrate (78) comprises a surface (90) with first and second contact pads (79, 80) and an electrically conductive pad (91) connected to the first contact pad (79) by a low-resistive connection (93). The chip (71) is attached to the substrate (78) so that the mounting surface (83) is spaced apart from the first contact pad (75) and the electrically conductive pad (91). The mounting surface (83) overlaps partly the first contact pad (79) with a first overlapping area (B1) resulting in a first stray capacitor (C1) and the electrically conductive pad (91) with a second overlapping area (B3) resulting in a second stray capacitor (C3). The first contact pad (79) and the electrically conductive pad (91) are arranged on the surface (90) of the substrate (78) such that, if the chip (21) is misaligned laterally in respect to the surface (90), then the first overlapping area (B1) increases while the second overlapping area (B3) decreases, or the first overlapping area (B1) decreases while the second overlapping area (B3) increases. |
