摘要： A Secure Digital device including a PCBA having passive components mounted on a PCB using surface mount technology (SMT) techniques, and active components (e.g., controller and flash memory) mounted using chip-on-board (COB) techniques. The components are mounted only on one side of the PCB, and then a molded plastic casing is formed over both sides of the PCB such that the components are encased in the plastic, and a thin plastic layer is formed over the PCB surface opposite to the components. The molded plastic casing is formed to include openings that expose metal contacts provided on the PCB, and ribs that separate the openings. The molded plastic casing defines a pre-molded switch slot that facilitates an insert-in switch assembly process for mounting a write protect switch. The write protect switch includes a movable switch button engaged in the switch slot, and a switch cap secured over the switch slot.

摘要： According to certain embodiments of the invention, a flash memory card is manufactured using COB processes on a PCB panel with multiple micro cards PCB substrates. These micro memory cards are laid out in an array of 3×5 matrixes of micro cards PCB substrates. A method of molding over a PCBA is utilized, contrary to a conventional method of having two or more pieces of package components to tape together. This results in a simpler structure without the notch which enables easier singulation process and the package is moisture resistance. The final product is a single piece versus two or three pieces glued up pieces and would not separate from pieces. The final product has high water and moisture resistance, low cost and fast manufacturing throughput, no seam and aesthetically more appeasing, can stack more layers of flash memory die, and be maximized XY spaces to accommodate larger size flash memory die.

摘要： A method for fabricating MicroSD devices includes forming a PCB panel having multiple PCBs arranged in parallel rows, with each PCB connected to its neighboring PCBs in each row by relatively narrow connecting bridge pieces, and separated from PCBs of adjacent rows by elongated stamped out blank slots. Passive components are attached by conventional surface mount technology (SMT) techniques. IC chips, including a MicroSD controller chip and a flash memory chip, are attached to the PCB by wire bonding or other chip-on-board (COB) technique. A molded housing is then formed over the IC chips and passive components using a mold that prevents formation of plastic on the upper surface of each PCB. The connecting bridge pieces are then cut using a used to connect each PCB to a PCB panel are then cut using a rotary saw. A front edge chamfer process is then performed.

摘要： ESD protection for a portable electronic device is provided by sandwiching a metal ground layer between prepreg (i.e., FR4 or other non-conductive PCB material) layers to form an ESD preventive PCB structure, where the metal ground layer is electrically connected to one or more of the integrated circuit (IC) components (e.g., at least one controller die, a non-volatile memory die, oscillator and passive components) that are mounted on the PCB by way of conductive via structures, and is accessible by way of one or more conductive anchor hole structures to external grounding structures. The one or more conductive anchor hole structures are positioned such that the metal ground layer is automatically electrically connected to the chassis ground of a host system when the portable device is coupled to a plug structure of the host system, e.g., by way of a metal connector jacket.
