FLUID EJECTION ASSEMBLY

摘要

PROBLEM TO BE SOLVED: To provide a fluid ejection assembly capable of surely forming an image of high quality at minimum cost. SOLUTION: The fluid ejection assembly has an ejection head carrier 72; a rigid substrate 62 formed to the outline of the ejection head carrier to be fixedly positioned relative to the ejection head carrier; a conductive pattern 64 defined on the rigid substrate and configured to transmit an electric signal to an ejection head 70; and an overmolding configured to cover at least a part of the conductive pattern by creating a substantially fluid-tight seal that limits the exposure of a part of the conductive pattern to a degenerative substance.
