Abstract
A method is provided for making a multi-fluid cartridge for holding multiple fluids in segregated containment localities. The cartridge body contains fluid supply paths in fluid flow communication with the containment localities. A nozzle plate is attached to a device side of each of a plurality of defined ejection head substrates on a semiconductor wafer. Each of the ejection head substrates has a fluid supply side and two or more fluid flow paths therein for supplying fluid from the supply side to the device side thereof. The fluid flow paths in the ejection head substrates have a flow path density of greater than about 1.0 flow paths per millimeter. The wafer is diced to provide a plurality of micro-fluid ejection device structures. A circuit device is attached to the device side of each of the substrates. An adhesive is stencil printed with a bond line density of at least about 1.2 mmon the micro-fluid ejection device structures or on the cartridge body. At least one of the micro-fluid ejection device structures and attached circuit is adhesively bonded to the cartridge body for flow of fluid from the containment localities to the device side thereof.
