    Abstract: A device may include a substrate, a first fluid processing chip, a second fluid processing chip, a tapered channel, and a fluid actuator. The first fluid processing chip may be disposed on the substrate and may process a micro-volume of fluid. The second fluid processing chip may be disposed on the substrate and co-planar with the first fluid processing chip. The second fluid processing chip may process at least a portion of the micro-volume of fluid. The tapered channel may be disposed between the first and second fluid processing chips to transport the at least the portion of the micro-volume of fluid from the first fluid processing chip to the second fluid processing chip. The fluid actuator may be disposed proximate to the tapered channel and may control movement of the at least the portion of the micro-volume of fluid within the tapered channel.

    Abstract: An ink delivery device is described. The ink delivery device includes an ink die with a first surface. The ink delivery device also includes an overmold to encapsulate a number of surfaces of the ink die. The overmold has a second surface that is wider than the first surface. The second surface receives an adhesive to attach the ink delivery device to a printhead. The ink delivery device also includes an ink slot passing through the overmold and at least a portion of the ink die.

    Abstract: In one example, a fluid flow structure includes a fluid dispensing micro device embedded in a molding having a channel therein through which fluid may flow directly to the device. The device contains multiple fluid ejectors and multiple fluid chambers each near an ejector. Each chamber has an inlet through which fluid from the channel may enter the chamber and an outlet through which fluid may be ejected from the chamber. A perimeter of the channel surrounds the inlets but is otherwise unconstrained in size by the size of the device.
