    Abstract: This disclosure relates to rapid and repeatable tests that can be used to evaluate the interfacial adhesion of coatings to substrates. In particular embodiments, tests are used to assess the resistance of anodic oxides to delamination from aluminum substrates. The tests can be conducted using standard hardness test equipment such as a Vickers indenter, and yield more controlled, repeatable results than a large sample of life-cycle tests such as rock tumble tests. In particular embodiments, the tests involve forming an array of multiple indentations within the substrate such that stressed regions where the coating will likely delaminate are formed and evaluated.

    Abstract: Electronic devices, such as mobile communication devices, may include several enhancements and modification not found on traditional electronic devices. An electronic device can include a circuit board assembly that includes stacked layers of circuit components that are retained in a stacked configuration and operably connected to each other by retention features such as solder joints. Features can be provided for structural support and thermal mitigation. A battery assembly can accommodate nesting of other components, such as display components, within one or more recesses defined by variable thickness along different regions of the battery assemblies. The battery assembly can further provide a slim profile by including notches to accommodate the increased thickness of a pouch having folded flaps to seal a cell module of the battery assembly.

    Abstract: Embodiments are directed to an enclosure for an electronic device. In one aspect, an embodiment includes an enclosure having an enclosure component and an internal component that may be affixed along a bonding region. The enclosure component may be formed from an enclosure material and defines an exterior surface of the enclosure and an opening configured to receive a display. The internal component may be formed from a metal material different than the enclosure material. The bonding region may include an interstitial material that has a melting temperature that is less than a melting temperature of either one of the enclosure material or the metal material. The bonding region may also include one or more of the enclosure material or the metal material.

    Abstract: Methods of forming anodic oxide coatings on high strength aluminum alloys are described. Methods involve preventing or reducing the formation of interface-weakening species, such as zinc-sulfur compounds, at an interface between an anodic oxide coating and underlying aluminum alloy substrate during anodizing. In some embodiments, a micro-alloying element is added in very small amounts to an aluminum alloy substrate to prevent enrichment of zinc at the anodic oxide and substrate interface, thereby reducing or preventing formation of the zinc-sulfur interface-weakening species. In some embodiments, a sulfur-scavenging species is added to an aluminum alloy substrate to prevent sulfur from a sulfuric acid anodizing bath from binding with zinc and forming the zinc-sulfur interface-weakening species at the anodic oxide and substrate interface. In some embodiments, a micro-alloying element and a sulfur-scavenging species are added to an aluminum alloy substrate. Resultant anodic oxide coatings have minimal or no discoloration.
