An extended USB plug connector includes a connector substrate including a frontend having a first set of electrical contact pins disposed thereon and a backend having a second set of electrical contact pins disposed thereon. The first set includes a first row of electrical contact pins disposed on a top surface of the connector substrate and a second row of electrical contact pins disposed in parallel with the first row of electrical contact pins and interior to the first row of electrical contact pins, where the second row includes more electrical contact pins than the first row. The second set of electrical contact pins includes a number of electrical contact pins equal to the first row and second row of electrical contact pins in total. The second set of electrical contact pins are used to connect to corresponding electrical contact pads disposed on a printed circuit board assembly having a USB controller and flash memory devices disposed thereon.

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.

Molded memory card with write protection switch assembly

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&#xd7;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.

High throughput manufacturing method for micro flash memory cards

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 using a rotary saw. A front edge chamfer process is then performed.

A microSD-to-SD adaptor card includes a base substrate having a lead frame structure, a protective cap forming a chamber that encloses eight microSD contact pins of the lead frame structure, and a thermoset plastic casing formed over the protective cap and exposed portions of the base substrate to provide the adaptor card with standard SD card dimensions. A rear opening facilitates insertion of a standard microSD card, whereby the eight contact pads on the microSD card are contacted by the eight microSD contact pins inside the chamber to allow electrical signals generated by the microSD card to be transmitted to a host system by way of a standard SD socket. A grip anchor pin is disposed inside the chamber to engage a grip notch disposed on the microSD card. A pre-molded switch slot is provided on the molded plastic casing, and an insert-in write protect switch is mounted after molding.

A USB device including a bistable mechanism that serves to bias a plug connector into one of two stable states, where the first stable state is associated with a retracted position in which the plug connector is fully retracted inside a housing, and the second stable state is associated with a deployed position in which the plug connector extends through the front opening for coupling to a host system. Movement of the plug connector form the retracted to the deployed position is performed by manually applying a force to a handle portion that protrudes through a slot defined in the housing. The bistable mechanism resists the deploying force until an equilibrium point is reach, after which the bistable mechanism releases stored potential energy to complete the deploying process and to maintain the plug connector is the deployed position.
