Abstract
An inkjet printhead assembly includes a substrate having a non-planar surface and a plurality of adhesive quantities each disposed on the non-planar surface of the substrate. As such, a plurality of printhead dies are each adhered to the non-planar surface of the substrate by one of the adhesive quantities. A thickness of at least one of the adhesive quantities varies from the thickness of another of the adhesive quantities such that the thickness of the adhesive quantities compensates for the non-planar surface of the substrate. Thus, the adhesive quantities support the printhead dies and establish a substantially coplanar relationship among the printhead dies.
