1. A suspension assembly comprising:
a rigid interposer circuit;
a sensor mounting region on the rigid interposer circuit; and
one or more flexible circuits including a first flexible circuit portion and a second flexible circuit portion configured to electrically couple the rigid interposer circuit to a printed circuit board, wherein each of the first flexible circuit portion and second flexible circuit portion are each disposed around a corner of the rigid interposer circuit and include one or more angled bends including a first angled bend comprising a first portion configured to connect to the rigid interposer circuit and a second portion angled substantially perpendicular relative to a first plane to the first portion and configured to connect to the printed circuit board that provide a reduced stiffness to enable movement of the rigid interposer circuit with respect to the printed circuit board, and a second angled bend bending the second portion such that a first part of the second portion is angled substantially perpendicular to a second part of the second portion relative to a second plane, the first plane being perpendicular to the second plane, and wherein second angled bends of each of first flexible circuit portion and second flexible circuit portion are bent around different corners of the rigid interposer circuit such that each of the first part and second part of the second portions are in parallel with edges of the rigid interposer circuit, wherein the second portion of each of the one or more flexible circuits extends outward from the first angled bend and includes an attachment feature to reduce a stress on the suspension assembly from motion in a z-axis direction and a bonded tail region adjacent to the attachment feature and comprising a series of bonds for electrically connecting to the printed circuit board.
