Abstract

A fluid-ejection assembly includes a die, a substrate, ribs, and adhesive. The die has nozzles through which fluid is ejected. The substrate provides the fluid to the die. The ribs are within the substrate, and have rounded corners. The rounded corners are adapted to provide a predetermined characteristic. The adhesive affixes the die to the substrate.
