Abstract
Examples include a fluid ejection device comprising a molded panel, an ejection die molded in the molded panel, and an integrated circuit molded in the molded panel. The ejection die comprises ejection nozzles to selectively dispense printing material. The integrated circuit receives nozzle data and controls the selective dispensation of printing material by the ejection nozzles based at least in part on the nozzle data. The molded panel has a fluid communication channel formed therethrough and fluidly connected to the ejection die.
Claims14
A fluid ejection device comprising:
- a molded panel having a fluid communication channel formed therethrough;
- at least one ejection die molded to the molded panel, the at least one ejection die comprising a plurality of ejection nozzles that are fluidly connected to the fluid communication channel, each ejection nozzle to selectively dispense printing material received from the fluid communication channel;
- and
- an integrated circuit molded into the panel and electrically connected to the ejection die, the integrated circuit to:
- receive nozzle data and control selective dispensation of printing material via the plurality of ejection nozzles based at least in part on the nozzle data.
A process comprising:
- arranging a plurality of ejection dies, each ejection die comprising a plurality of ejection nozzles;
- arranging a respective integrated circuit proximate each respective ejection die of the plurality, the respective integrated circuit to control selective dispensation of printing material via the ejection nozzles of the respective ejection die;
- forming a molded panel including the plurality of ejection dies and the respective integrated circuits;
- electrically connecting each respective election die to the respective integrated circuit with electrical conducting elements on a front surface of the molded panel;
- and
- removing portions of the molded panel to thereby form a respective fluid communication channel for each respective ejection die of the plurality, each respective fluid communication channel being thereby fluidly connected to the ejection nozzles of the respective ejection die.
A printing fluid cartridge comprising:
- a container to contain printing material;
- and
- a fluid ejection device coupled to the container, the fluid ejection device comprising:
- a molded panel having a fluid communication channel formed therein, the fluid communication channel fluidly connected to the container;
- an ejection die molded into the molded panel, the ejection die comprising a plurality of ejection nozzles, the ejection nozzles fluidly connected to the fluid communication channel, and the ejection nozzles to selectively dispense printing material received from the container via the fluid communication channel;
- and
- an integrated circuit molded into the panel and electrically connected to the ejection nozzles, the integrated circuit to control selective dispensation of printing material via the plurality of ejection nozzles.
