The device includes an electrical interconnect element in contact with the contact pad of each of the fluid ejection dies to electrically interconnect the plurality of fluid ejection dies.
Claims21
1-20. (canceled)
The device of claim 21, wherein each of the fluid ejection dies includes a data contact pad for data transfer, and wherein the electrical interconnect element is in contact with the data contact pad.
A device, comprising:
- a plurality of fluid ejection dies, wherein each of the fluid ejection dies includes a contact pad and a plurality of fluid actuation devices;
- and
- an electrical interconnect element in contact with the contact pad of each of the fluid ejection dies to electrically interconnect the plurality of fluid ejection dies.
The device of claim 27, wherein each of the electrical interconnect elements is in contact with the data contact pad of one of the fluid ejection dies.
The device of claim 27, wherein at least one of the electrical interconnect elements extends across all of the fluid ejection dies of the device.
The device of claim 27, wherein at least one of the electrical interconnect elements includes a u-shaped element with two vertical portions and a horizontal portion, and wherein the horizontal portion is in contact with the data contact pad of one of the fluid ejection dies.
A device, comprising:
- a carrier including a window;
- a fluid ejection die attached to the carrier and positioned within the window, wherein the fluid ejection die includes a contact pad and a plurality of fluid actuation devices;
- and
- an electrical interconnect element that extends across the window and is in contact with the contact pad of the fluid ejection die.
A fluid ejection device, comprising:
- a carrier including a plurality of electrical interconnect elements;
- at least three fluid ejection dies attached to the carrier, wherein each of the fluid ejection dies includes a plurality of contact pads and a plurality of fluid actuation devices, and wherein each of the electrical interconnect elements is in contact with one of the contact pads of each of the fluid ejection dies.
