Abstract
A die for a printhead is described herein. The die includes a number of fluid feed holes disposed in a line parallel to a longitudinal axis of the die, wherein the fluid feed holes are formed through a substrate of the die. The die includes a number of fluidic actuators, proximate to the fluid feed holes, to eject fluid received from the fluid feed holes. Circuitry on the die operates the fluidic actuators, wherein traces are provided in layers between adjacent fluid feed holes, connecting circuitry on each side of the fluid feed holes.
Claims13
A die for a printhead, comprising:
- a substrate having a plurality of fluid feed holes formed through the substrate, the plurality of fluid feed holes disposed in a line parallel to a longitudinal axis of the die;
- a plurality of fluidic actuators, proximate to the plurality of fluid feed holes, to eject fluid received from the plurality of fluid feed holes;
- logic circuitry and logic power lines disposed on a first side of the plurality of fluid feed holes, the logic circuitry to operate the plurality of fluidic actuators, the logic power lines being low-voltage power lines:
- power circuitry and power circuit power lines disposed on a second side of the plurality of fluid feed holes opposite the first side, the power circuitry to provide power to the plurality of fluidic actuators, the power circuit power lines being high-voltage power lines:
- and
- traces in layers between adjacent fluid feed holes of the plurality of fluid feed holes, connecting the logic circuitry and the power circuitry on each side of the plurality of fluid feed holes.
