Abstract: A printhead includes a printhead die and an interconnect substrate. The printhead die includes a surface. The interconnect substrate includes electrical circuitry and a surface. The electrical circuitry is in electrical communication with the printhead die through a plurality of electrical connections. An encapsulant structure is positioned to encapsulate the plurality of electrical connections, and includes a barrier portion and a filler portion. The barrier portion includes a first wall and a second wall. The first wall is in contact with the surface of the printhead die and the second wall is in contact with the surface of the interconnect substrate. The filler portion is in contact with the plurality of electrical connections and positioned between the first wall of the barrier portion and the second wall of the barrier portion.

Abstract: A process for precision patterning or cutting of a sheet stock, such as an adhesive tape, includes the step of irradiating a surface of a sheet stock with an irradiation source to pattern or cut a part in the sheet stock. The method is particularly useful for precision cutting adhesive members, such as adhesive fluid seals, for an inkjet print cartridge.
