Flash memory device

Flash memory device having a retractable cap

Retractable flash memory device

A portable memory card including a molded plastic casing formed over a memory device and other circuits mounted on a substrate such that the molding material extends over side edges of the substrate to provide accurate width and thickness dimensions. Contact pads are formed on a lower surface of the PCBA substrate, which is exposed through a bottom of the casing. The PCBA is fabricated on a substrate carrier, then positioned inside of a mold assembly. During the molding process, a rod extends from an upper portion of the mold assembly and pushes the substrate against the lower surface. A vacuum is then applied to hold the substrate against the lower surface of the mold, and the rod is subsequently withdrawn from the mold cavity during injection of the molten molding material. A single cavity mold assembly provides molding material extends over front and back edges of the memory card.

A low-profile Universal-Serial-Bus (USB) device includes a PCBA in which all passive components and unpackaged IC chips are attached to a single side of a PCB opposite to the metal contacts. The IC chips include, for example, a USB controller chip and a flash memory chip, or a single-chip (combined USB controller/flash memory) chip. Multiple flash IC chips are optionally stacked to increase storage capacity. The IC chip(s) are attached to the PCB by wire bonding or other chip-on-board (COB) technique. The passive components are attached by conventional surface mount technology (SMT) techniques. A molded housing is then formed over the IC chips and passive components such that the device has a uniform thickness. The low-profile USB device is optionally used as a modular insert that is mounted onto a metal case to provide a USB assembly having a plug shell similar to a standard USB male connector.

An MMC/SD core unit includes a PCBA in which all passive components and unpackaged IC chips are attached to a single side of a PCB opposite to the metal contacts. The IC chips include, for example, a controller chip and a flash memory chip, or a single-chip (combined controller/flash memory) chip. Multiple flash IC chips are optionally stacked to increase storage capacity. The IC chip(s) are attached to the PCB by wire bonding or other chip-on-board (COB) technique. The passive components are attached by conventional surface mount technology (SMT) techniques. A molded housing is then formed over the IC chips and passive components such that the device has a uniform thickness. The MMC/SD core unit is then inserted or otherwise mounted in an eternal casing to provide a finished MMC/SD device.

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.

Embodiments of a plug and cap of a Universal-Serial-Bus (USB) device have been presented. In one embodiment, a USB device includes a main body, a piece of string, and a cap. The main body has a printed circuit board assembly (PCBA) and a casing, wherein the PCBA is partially housed in the casing, and the PCBA further includes a USB connector protruding out of the casing at a first end of the casing. The piece of string is coupled to the main body and the cap. The cap is detachably coupled to the first end of the casing of the main body to cover the USB connector, wherein the cap remains indirectly coupled to the casing via the piece of string when the cap is detached from the first end of the casing to expose the USB connector.

A card-type electronic apparatus such as an SD card, a CF card, a Memory Stick card, or a USB flash drive is formed from an upper and lower cover that are bonded together at an interior seam formed using ultrasonic joining. Lower sidewalls on the lower cover create an installation pocket for the upper cover. The installation pocket not only simplifies alignment between the upper and lower covers, but also contains any bonder material overflow that might otherwise affect the external dimensions of the apparatus housing. The lower sidewalls can completely surround the upper cover, for drop in installation. Alternatively, the lower sidewalls can partially surround the upper cover, so that the upper cover can be slid into place during assembly.

A Universal-Serial-Bus (USB) device includes a PCBA mounted inside a plastic housing molded from a hard plastic (e.g., PC), and includes a handle portion mounted over a body section of the PCBA, and a plug support portion that is snap-coupled onto the housing and disposed under a plug section of the PCBA. The plug shell portion of the housing is integrally connected to (i.e., molded at the same time as or connected by way of molding to) the handle portion, and combines with the plug support structure extending under the plug section of the PCBA to form 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.

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 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 connected together to form a rigid frame.

A USB device includes a printed circuit board assembly (PCBA), a metal shell secured to a front of the PCBA, a plastic frame secured to a rear of the PCBA, and a rubber case including a case body covering the plastic frame case such that a plug shell connector extends from the second front end opening. A rubber cap is removably mounted over the plug shell connector to entirely enclose the USB device when not in use. The rubber case is molded to include a cosmetic feature, such as a soccer ball, a sports team logo, or a company logo.
