An actuator assembly including a flexible printed circuit and a method for making such an actuator assembly are provided. The flexible printed circuit includes a body having a top side and a bottom side, with the body defining a plurality of bumps extending from the bottom side. A first bump of the plurality of bumps is disposed adjacent to a second bump of the plurality of bumps, and the body further defines at least one relief configured to reduce movement of the second bump caused by movement of the first bump. The flexible printed circuit also includes a plurality of contact pads disposed on the bottom side of the body at least partially at the plurality of bumps, with the plurality of contacts pads being configured to be electrically coupled to a power source and to a piezoelectric transducer. |
