    Abstract: A flex circuit board provides islands of electrically isolated material surrounding openings in the flex circuit board to preserve fluid integrity of passageways passing through an electrically insulating layer of the flex circuit board. The electrically isolated islands surround exits of the passageways through the electrically insulating material and extend the passageways through an electrically conductive layer of the flex circuit board. Consequently, fluid passing through the passageways and electrically isolated islands in the flex circuit board is not subjected to electrical current.

    Abstract: A method and structure for a printhead including a plurality of electrostatic actuators may include the formation of a first conductive layer, a first dielectric layer over the first conductive layer, and a second dielectric layer over the first dielectric layer. The first and second dielectric layers may be patterned to expose the first conductive layer, then sidewalls of the first dielectric layer may be isotropically etched to recess the sidewalls under the second dielectric layer. A self-patterned second conductive layer may be formed to include a first portion that forms at least a portion of an actuator electrode and physically and electrically contacts the first conductive layer, and a second portion that physically contacts the second dielectric layer. An actuator membrane may be diffusion bonded to the second dielectric layer using the second portion of the second conductive layer.

    Abstract: 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.
