Patent ID: 8814326

Claim:
An actuator assembly for an inkjet printer, comprising: an array of piezoelectric actuators; a diaphragm coupled with the array of piezoelectric actuators, wherein the diaphragm is configured to displace a volume of ink when one or more of the array of piezoelectric elements is excited; a standoff layer disposed adjacent to the array of piezoelectric actuators, such that the array of piezoelectric actuators is disposed between the standoff layer and the diaphragm, the standoff layer defining apertures therethrough aligned with at least some of the array of piezoelectric transducers; and a flexible printed circuit disposed adjacent to the standoff layer, the flexible printed circuit comprising: a body having a top side and a bottom side, the body defining a plurality of bumps extending from the bottom side, the plurality of bumps being aligned with and extending at least partially through the apertures of the standoff layer; a first embossed contact pad disposed on the bottom side of the body and at least partially at one or more of the plurality of bumps, the first embossed contact pad physically contacting at least one of the array of piezoelectric transducers; and a second embossed contact pad disposed on the bottom side of the body and at least partially at one or more of the plurality of bumps, the second embossed contact pad physically contacting at least one of the array of piezoelectric elements, wherein the body comprises at least one cutout relief configured to reduce movement of the second embossed contact pad caused by movement of the first embossed contact pad.
