Abstract
An inkjet printer printhead has a layering of a flexible polymer tape, a patterned barrier material that is acting as an adhesive as well as ink channels, and a substrate that has a plurality of ink expulsion devices. Each of the ink propulsion devices is aligned with an orifice hole ablated in the flexible polymer tape where the ink expels and patterns the medium beyond. To keep adhesives and encapsulants required in the assembly of the inkjet printer printhead out of the critical ink channel area near the orifice holes, fluid accumulation channels are ablated into the flexible polymer tape in a strategic location between the adhesive bead and the ink channel. These accumulation channels function as both a diversion a containment point for the excess flow of adhesive.
