Examples of molded substrates are described herein. In some examples, a molded substrate may support integrated circuitry. In some examples, the molded substrate and the integrated circuitry are included in a circuitry package for a replaceable print component. In some examples, the molded substrate is relatively flat. In some examples, molding remnants may be on the molded substrate.

Molded substrates

A cassette may include a substrate and a die coupled to the substrate wherein the substrate is made of modified polyetherimide (PEI). A system for ejecting a fluid into an assay may include at least one dispense head, the at least one dispense head including a substrate and a die coupled to the substrate wherein the substrate is made of modified polyetherimide (PEI).

Cassette substrates made of polyetherimide

An electrical connection is encapsulated by dispensing an encapsulant on a first side of the electrical connection only, and directing the encapsulant to a second side of the electrical connection from the first side, where the second side generally faces opposite the first side.

Encapsulating electrical connections

An ink cartridge for an ink jet printer includes a substratum and a cover attached to the substratum and having an aperture provided therein. A printhead is attached to the substratum and provided at least partially within the aperture. At least one connector extends from the printhead into the aperture, and an adhesive material covers at least a portion of the at least one connector. At least one barrier is provided for preventing the adhesive material from flowing to locations away from the at least one connector.
