A tube interconnect includes a tube and a header overmolded about the tube.

Overmolded tube header

The described embodiments relate to methods and systems for forming die packages. In one exemplary embodiment, the method for forming die packages contacts interface areas of a die assembly to keep the interface areas free of an insulative material. The method distributes a flowable insulative material around portions of the die assembly.

Methods and systems for forming a die package

Embodiments of the present invention comprise containers for consumable substances, such as ink, and the corresponding receiving stations, such as inkjet printers. The containers and receiving stations have mating keying features indicative of a characteristic of the consumable substance, such as the ink family. Embodiments of the mating features include protuberances with a T-shaped cross section, and corresponding T-shaped slots. Preferred embodiments of containers and receiving stations are disclosed having two keying features with four unique orientations per feature, for a total 16 key permutations.

Method and apparatus for keying ink supply containers

A multi-compartment ink-jet cartridge body structure, which includes a unitary body having a plurality of ink reservoir compartments. Each compartment includes an outlet port through which ink passes to feed the ink to an ink-jet printhead nozzle array. The body further includes a printhead nozzle array mounting region, and an ink manifold structure including a plurality of corresponding ink channels each leading from a corresponding outlet port to a feed opening formed at the printhead mounting region. The body and manifold structure are formed as a unitary one-piece structure. A lid is attached to the unitary body to cover the compartments. The body includes an external wall, and an access opening is formed in the wall adjacent the manifold structure. A seal structure attached to the body for sealing the access opening. The body structure can be fabricated by a plastic material using an injection molding process. The access opening is a mold slide insert opening in the nosepiece area, and the seal structure seals the slide insert opening. The molding process can be carried out by a three piece mold set to fabricate the body.
