Abstract
Systems and methods for aligning a transfer head assembly with a substrate are disclosed. In an embodiment a pivot mount is used for generating a feedback signal in a closed-loop motion control system. In an embodiment, the pivot mount includes primary spring arms and secondary spring arms extending between a pivot platform and a base of the pivot mount. The secondary spring arms are characterized by a lower stiffness than the primary spring arms, and strain sensing elements are located along the secondary spring arms.
