7. A suspension assembly comprising:
a baseplate;
a load beam connected to the baseplate by a hinge;
a gimbal mounted to the load beam, wherein the gimbal comprises a base portion and a tongue that are joined together by a neck portion, wherein the base portion includes a first proximal edge facing away from the tongue;
a circuit mounted on the gimbal, wherein the circuit includes a portion mounted to the base portion that includes a circuit extension region that extends beyond the first proximal edge of the base portion, wherein the circuit extension region includes a second proximal edge facing away from the tongue; and
a first PZT actuator and a second PZT actuator mounted to the suspension assembly and electrically connected to the circuit, for displacing the tongue relative to the base portion;
wherein the circuit extension region has a circuit extension region width W of at least 0.1 mm as measured in a direction extending away from the tongue relative to a furthest extending portion of the first proximal edge in the direction extending away from the tongue and a furthest extending portion of the second proximal edge in the direction extending away from the tongue.
