Abstract:
A handheld electronic device may be provided that contains a conductive housing and other conductive elements. The conductive elements may form an antenna ground plane. One or more antennas for the handheld electronic device may be formed from the ground plane and one or more associated antenna resonating elements. Transceiver circuitry may be connected to the resonating elements by transmission lines such as coaxial cables. Ferrules may be crimped to the coaxial cables. A bracket with extending members may be crimped over the ferrules to ground the coaxial cables to the housing and other conductive elements in the ground plane. The ground plane may contain an antenna slot. A dock connector and flex circuit may overlap the slot in a way that does not affect the resonant frequency of the slot. Electrical components may be isolated from the antenna using isolation elements such as inductors and resistors.

Various systems of an electronic deice and methods for manufacturing the same are provided. In some embodiments, a routing assembly is provided that may not only route a cable along a circuit board, but that may also shield and electronic component or secure an electronic component to the circuit board. In some other embodiments, there is provided a mechanism for electrically coupling two components of an electronic device that may also be visually appealing in the context of other portions of the electronic device.
Abstract:
A clamping apparatus includes a base, a vertical support member coupled to the base, and a head member coupled to the vertical support member. The head member is configured to receive and engage a portion of a coaxial cable. Additionally, the base is configured to engage through a through hole or slot arranged through a substrate and provide electrical communication between a portion of the coaxial cable and the substrate.

Abstract:
An electronic device may have a display overlapped by a cover layer. Portions of the surface of the display and cover layer may have curved profiles. The display may include a flexible substrate and may have bent edge portions protruding from a central region. Gaps may be formed between regions of pixels on a common substrate or between separate display panels. An image transport layer formed from a coherent fiber bundle or a layer of Anderson localization material configured to exhibit two-dimensional transverse Anderson localization of light may have an input surface that receives an image from adjacent display pixels and an output surface on which the image is displayed. The output surface may have a curved profile and may exhibit compound curvature. The input surface may have a profile with curved portions or other shapes. Image transport layers can be used to cover gaps between sets of pixels.

An electronic device including a housing defining an aperture, a display component positioned in the aperture, and a filler material at least partially surrounding a periphery of the display component. The filler material can contact the display component and a portion of the housing defining the aperture.
Abstract:
An electronic device may have an electrical component with a moving portion. The moving portion of the electrical component may include a moving mass and may include coils or other circuitry coupled to the moving mass. The moving mass may be supported within a support structure such as a housing structure. Springs may be coupled between walls in the housing structure and end portions of the moving mass. The coils or other circuitry on the moving mass may be coupled to flexible printed circuit cables. The flexible printed circuit cables may be coupled to the coils at the ends of the moving mass adjacent to the springs. The flexible printed circuit cables may have localized stiffeners that help prevent damage to metal traces in the cables during cable bending. The cables may have U-shapes or other suitable shapes.
Abstract:
Electronic device housing structures and other structures may be formed from molded plastic. Plastic structures such as injection molding housing structures and other structures may be provided with openings. An opening may have sidewall surfaces. Machining operations and other techniques may be used in forming the openings. Openings may be processed to enhance resistance to stress-induced cracking of the plastic structures along the sidewall surfaces. Cracking resistance may be obtained by activating the surface using heat or laser treatment and by electroplating the activated surface to form a metal liner structure. Surface treatments using applied liquid chemicals or heat may form a treated layer on the surface of an opening with enhanced cracking resistance. A plastic sleeve or other insert may form a liner structure in an opening that resists cracking. Liner structures may also be formed by applying heat or light to a coating in an opening.
Abstract:
An electrical component may be mounted on a substrate such as a ceramic substrate. Contacts may be formed on upper and lower surfaces of the substrate. The electrical component may be soldered to the contacts on the upper surface. The contacts on the lower surface may be used to solder the substrate to a printed circuit. During manufacturing, it may be desirable to use metal traces on a ceramic panel to make connections to contacts on the substrate. Following singulation of the ceramic panel to form the ceramic substrate, some of the metal traces may run to the edge of the ceramic substrate. A folded tab of the printed circuit may form a shield that covers these exposed traces. A divided metal-coated groove or a row of divided metal-coated vias running along each edge of the substrate may also provide shielding.
