Abstract:
1. A method of making a multi-fluid cartridge for holding multiple fluids in segregated containment localities, a cartridge body containing fluid supply paths in fluid flow communication with the containment localities, the method comprising: printing an adhesive with a bond line density of at least about 1.2 mm adhesively bonding a circuit device, attached to the micro-fluid ejection device structure, to the cartridge body for flow of fluid from containment localities to a device side of the micro-fluid ejection device structure, wherein the act of printing comprises one of stencil printing and screen printing, and wherein the micro-fluid ejection device structure is one of a plurality of micro-fluid ejection device structures diced from a wafer, each of the micro-fluid ejection device structures comprises an ejection head substrate and a nozzle plate, further comprising: applying a photoresist layer to the wafer adjacent a fluid supply side of the ejection head substrates; and photodefining fluid flow channels in the photoresist layer to provide fluid channels therein in fluid flow communication with fluid flow paths in the ejection head substrates.
