摘要:
A flash-memory-drive card has a Universal-Serial-Bus (USB) connector. The card has a printed-circuit board (PCB) that fits into a perimeter frame that surrounds the edges of the PCB. Metal or plastic upper and lower covers are snapped onto the frame to encapsulate the PCB. The USB connector can be a Full USB connector plug that extends from the perimeter frame and has a centerline approximately matching the PCB centerline for a balanced design, or can be a slim or reduced-height USB connector plug that has a frame closure bar that fits inside closure fittings on the perimeter frame. The USB connector can also be made from a frame extension that has four frame slots through the frame. The PCB has four PCB fingers that are inserted through the frame slots during assembly so that the PCB fingers fit within depressions in the frame extension to form the USB connector plug.

A memory module assembly includes two-plate heat sink attached to one or more of the integrated circuits (e.g., memory devices) of a memory module PCBA by adhesive. The adhesive is either heat-activated or heat-cured. The adhesive is applied to either the memory devices or the heat-sink plates, and then compressed between the heat-sink plates and memory module using a fixture. The fixture is then passed through an oven to activate/cure the adhesive. The two heat sink plates are then secured by a clip to form a rigid frame.

A Serial Advanced Technology Attachment-based (SATA-based) flash memory device configured for coupling with a host machine. The device includes semiconductor memory configured for storing data and a plug having therein a plug cavity, the plug cavity having a generally L shape cavity for housing a set of SATA industry-standard signal pins in respective industry-standard positions with respect to the plug cavity. The plug additionally has a set of power pins that includes at least a first power pin. The SATA-based flash memory device employs a SATA protocol for exchanging the data with the host machine using the set of SATA industry-standard signal pins, the SATA-based flash memory device obtaining power via the set of power pins.

A Universal-Serial-Bus (USB) device includes a PCBA mounted inside a molded plastic housing structure such that metal contacts are exposed on a plug portion of the housing structure, and includes a metal plug shell attached to the housing structure such that an upper wall of the metal plug shell is spaced from the metal contacts by a predetermined gap distance. A USB controller IC is mounted onto a relatively narrow portion of the PCBA under the metal contacts to reduce overall length of the USB device. The metal plug shell is molded or snap-coupled onto tabs formed on the plug portion of the housing structure. An optional locking collar secures a rear edge of the metal plug shell to the housing structure. An optional rear cover is attached over a rear opening of the housing structure and secures a rear edge of the PCBA.

A portable memory device includes a molded housing and a printed circuit board assembly (PCBA) encased with the molded housing such that a plug connector extends from one end. A lower housing portion is produced by injection molding using a first apparatus, and then the lower housing portion is transferred to a second molding apparatus. The PCBA is mounted onto the lower housing such that the plug connector is received in a protected region. The second molding apparatus is then closed, and an upper housing portion is injected molded over the PBCA and exposed peripheral edges of the lower housing portion such that the upper housing portion becomes fused to the lower housing portion. Multiple lower housing portions connected together by plastic tethers to form a plastic strip, which facilitates efficient transfer to the second molding apparatus as a unit. The tethers are subsequently removed (e.g., singulated) to form individual memory devices.

A USB device in which all of the devices ICs are located on a lower surface of a PCB (i.e., opposite to the metal contacts) to minimize the device's thickness, and at least one of the ICs is positioned on a relatively narrow portion of the USB plug to minimize the device's length. A card-like carrier for protecting the USB device when not in use includes a frame-like base portion having peripheral walls surrounding a relatively wide main chamber, and an end portion that is attached to the base portion and includes end walls that define a relatively narrow slot communicating with the main chamber. The USB device plug structure is inserted through the main chamber into the slot until a front edge of the handle structure abuts the end walls, and then the device is rotated downward into the main chamber.

A Universal-Serial-Bus (USB) device includes a PCBA mounted inside a plastic housing molded from a hard plastic (e.g., PVC), and includes a handle portion mounted or molded over a body section of the PCBA, and a plug portion mounted or molded over a plug section of the PCBA. The plug portion of the housing is integrally connected to (i.e., molded at the same time as) the handle portion, and includes a plug substrate extending under the plug section of the PCBA and a plug shell that extends over the plug portion, forming a structural arrangement similar to a conventional male USB connector plug that allows access to metal contacts formed on the PCBA, but without having the plug shell soldered to the PCBA.

摘要:
A light-weight flash hard drive includes a printed circuit board assembly (PCBA) mounted in a housing formed by a plastic frame and a pair of metal panels that are mounted on the plastic frame over the PCBA. The PCBA includes a PC board and a plug connector that is mounted on a front edge of the PCB. The plastic frame includes first and second parallel side rails and a back end rail extending between back ends of the first and second side rails. The frame defines an open front end and a longitudinal platform for receiving and supporting the PCBA such that the plug connector is exposed through the open front end. The metal panels are either snap-coupled to the plastic frame or to each other. Alternatively, or in addition, an adhesive or insulating film is provided between the metal panels and the IC devices mounted on the PCBA.
