Abstract: This application relates to a method for forming an enclosure for a portable electronic device. The enclosure includes a metal substrate having a first b* value. The method includes forming an anodized layer that overlays and is formed from the metal substrate, wherein the anodized layer has a second b* value that is no greater than 0.3 of the first b* value and no less than 0.3 less than the first *b value.

Abstract: A component for an electronic device can include a metal alloy formed by a metal injection molding process. The metal alloy can have a composition of about 32 wt % to about 38 wt % cobalt and about 62 wt % to about 68 wt % iron.

Abstract: The embodiments described herein relate to forming anodized films that have a white appearance. In some embodiments, an anodized film having pores with light diffusing pore walls created by varying the current density during an anodizing process is described. In some embodiments, an anodized film having light diffusing micro-cracks created by a laser cracking procedure is described. In some embodiments, a sputtered layer of light diffusing aluminum is provided below an anodized film. In some embodiments, light diffusing particles are infused within openings of an anodized layer.

Abstract: The embodiments described herein relate to treatments for anodic layers. The methods described can be used to impart a white appearance for an anodized substrate. The anodized substrate can include a metal substrate and a porous anodic layer derived from the metal substrate. The porous anodic layer can include pores defined by pore walls and fissures formed within the pore walls. The fissures can act as a light scattering medium to diffusely reflect visible light. In some embodiments, the method can include forming fissures within the pore walls of the porous anodic layer. In some embodiments, exposing the porous anodic layer to an etching solution can form fissures. The method further includes removing a top portion of the porous anodic layer while retaining a portion of the porous anodic layer.

Abstract: An electronic receptacle connector includes a hybrid contact assembly that includes a contact plate that has multiple fingers, a contact positioned at a distal end of each finger and a conductor that runs along each finger and electrically couples each contact to an interconnect region positioned outside of the housing. The fingers are made from a first material and the contacts are made from a second material such that each of the first and the second materials can be independently optimized.

Abstract: An electroformed binary copper alloy comprising copper and X, where X is selected from the group consisting of Cr, Fe, W, Mo, B, Co, Ag, and P, having a yield strength of at least 600 MPa and an electrical conductivity of at least 20% IACS is disclosed.

Abstract: Techniques for forming a metal oxide from a metal substrate are disclosed. In some embodiments, the metal oxide can have an optical path difference between about 300 nm to about 1000 nm. The variations in optical path difference can impart the metal oxide to correspond to a range of pre-defined colors. In some embodiments, the optical path difference can impart the metal oxide to have an oxide color that is substantially similar to a color of a housing of a portable electronic device. In some embodiments, the metal oxide can be electrically conductive and the metal oxide can be utilized as an electrical contact of an electronic device to transmit and receive power and data from another electronic device.

Abstract: The embodiments described herein relate to forming white appearing metal oxide films by forming cracks within the metal oxide films. In some embodiments, the methods involve directing a laser beam at a metal oxide film causing portions of the metal oxide film to melt, cool, contract, and crack. The cracks have irregular surfaces that can diffusely reflect visible light incident a top surface of the metal oxide film, thereby imparting a white appearance to the metal oxide film. In some embodiments, the cracks are formed beneath a top surface of a metal oxide film, thereby leaving a continuous and uninterrupted metal oxide film top surface.

Abstract: Contacts that may be highly corrosion resistant, may be readily manufactured, and may conserve precious materials. One example may provide contacts having a layer of a precious-metal alloy to improve corrosion resistance. The precious-metal-alloy layer may be plated with a hard, durable, wear and corrosion resistant plating stack for further corrosion resistance and wear improvement. The resources consumed by a contact may be reduced by forming a bulk or substrate region of the contact using a more readily available material, such as copper or a material that is primarily copper based.
